To reach the Green Bank Observatory, you take the road less traveled, winding through scenic and remote regions of the Allegheny Mountains and the Monongahela National Forest of West Virginia. About an hour away, you’ll start to lose cell phone service. The Green Bank Observatory – a collection of radio telescopes that search the heavens for faint radio signals from black holes, pulsars, neutron stars or gravitational waves — sits near the heart of the United States National Radio Quiet Zone, a unique area the encompasses an area of approximately 13,000 square miles, spanning the border between Virginia and West Virginia.

Here in the NRQZ, human-generated radio transmissions are limited to shield the radio telescopes from Earth-based radio signals called RFI (Radio Frequency Interference), which are high-frequency electromagnetic waves that emanate from electronic devices such as computers, cell phones, microwave ovens, and even digital cameras. Even the weakest RFI signals can drown out the faint radio waves coming from the cosmos.

“You can only use basic, old-style film cameras here within 2 miles of the Green Bank Telescope,” said Paul Vosteen, Media Specialist at Green Bank Observatory who provided a tour of the facilities. Vosteen recounted a time he took a group out to see the gigantic (and very photogenic) 100-meter Green Bank Telescope (GBT) and unwittingly, a member of the group started snapping photos with a digital camera. While he quickly got the photographer stopped, Vosteen later coyly checked in with technicians who had been running diagnostics on the GBT that day. They were scratching their heads about a strange spike in signals earlier that morning. Turns out, it was the exact moment the photographer used their digital camera. 

“The slightest electronic signal can cause interference,” Vosteen explained. “We can only use diesel vehicles here on the premises because gasoline engines have spark plugs. Everything that sparks produces radio waves.” Diesel engines, on the other hand, ignite by compression.

To keep the amount of interference on-site in check, the observatory’s control room and the nearby Science Center’s exhibit hall are completely surrounded by copper Faraday cages, wire-mesh devices built into the walls to block electromagnetic signals. Even windows are covered with a thin wire mesh, and the heavy door to the control room opens and closes like an entrance to a high-security bank vault.

Green Bank is home to six large radio telescopes ranging in size from 14 meters to 100 meters in diameter. The 20-meter and the 40-foot telescopes are full-time educational telescopes used by students around the country.

The observatory also contains many relics of radio astronomy history. There’s an exact replica of the dipole array antenna Karl Jansky used when he discovered quite by accident that radio waves were emanating from the center of the Milky Way. That was the beginning of radio astronomy as we know it today. There’s also the actual parabolic dish radio telescope (the world’s first) built by Grote Reber in 1937 to follow up on Jansky’s detection. Then there’s the 85-foot Howard E. Tatel telescope that Frank Drake used in 1960 to perform the world’s first search for extraterrestrial intelligence with Project Ozma.

GBT – “Great Big Thing”

At 485 feet (148 meters) tall, the Robert C. Byrd Green Bank Telescope (GBT – sometimes called ‘Great Big Thing’ by locals) is the tallest and most eye-catching dish at the observatory, and the largest steerable radio telescope in the world. The maneuverability of its large 100-meter dish allows it to quickly track objects across its field of view, and see 85% of the sky.

While the GBT has been in operation since 2000, as we discussed in an article last week, a new upgrade for the telescope is under development. ngRADAR is a next-generation radar system that will allow the GBT to track and map asteroids with unprecedented resolution, making GBT the most advanced planetary radar system in the world. It will also be able to study comets, moons and planets in our Solar System. When finished it will not only help astronomers study the composition of other planetary bodies, but also help defend against potential large meteor strikes on Earth by mapping the precise trajectories of asteroids that cross Earth’s orbit.

Astronomers study the Universe by capturing light from stars, planets, and galaxies. But they can also study nearby objects by shining radio light on them and analyzing the signals that echo back. This is called planetary radar, and the process can reveal incredibly detailed information about our planetary neighbors.

“When astronomers are studying light that is being made by a star, or galaxy, they’re trying to figure out its properties,” said Patrick Taylor, the project director for ngRADAR and the radar division head for the National Radio Astronomy Observatory, in our article last week. “But with radar, we already know what the properties of the signals are, and we leverage that to figure out the properties of whatever we bounced the signals off of. That allows us to characterize planetary bodies – like their shape, speed, and trajectory. That’s especially important for hazardous objects that might stray too close to Earth.”

Previously, the workhorse for planetary radar was the 1,000-foot-diameter (305 meters) Arecibo Observatory which collapsed in 2020, as well as the Goldstone 70-meter dish in California, which is primarily used for communicating with spacecraft as part of NASA’s Deep Space Network. Taylor said that the idea for ngRADAR has been discussed for years — even before Arecibo’s demise — but with the loss of Arecibo, the upgrade is even more important.

Radar signals transmitted by the ngRADAR at the GBT will reflect off astronomical objects, and those reflected signals will be received by the Very Long Baseline Array (VLBA), a network of ten observing stations located across the United States.

“The idea is for GBT is to do the transmitting almost constantly and the VLBA — either all ten of those or any subset of those telescopes — doing the receiving,” said Taylor. “This new system will allow us to characterize the surfaces of many different objects in a different frequency or wavelength that hasn’t been used before.”

Radio Frequencies

All light travels through space in waves – think of how ripples move across a pond. Each ripple has a peak and a trough, which is called a cycle. An object emitting radio waves produces many cycles in a very short period. During each cycle, the wave moves a short distance, which is called its wavelength. Radio waves have the longest wavelengths in the electromagnetic spectrum. They range from sub-millimeter lengths to over 100 kilometers.

For radio waves of all wavelengths, the number of cycles per second is called a frequency, with one cycle per second being one hertz. That means one thousand cycles per second is a kilohertz and a billion cycles per second is a gigahertz. Radio astronomers are interested in objects in a wide range of frequencies, but mostly from between 3 kilohertz and about 900 gigahertz.

“Arecibo worked at 2.38 gigahertz, the Goldstone 70-meter primarily works at 8.56 gigahertz,” said Taylor. “For ngRADAR, we are looking at even higher frequencies, at 13.7 gigahertz, something that really hasn’t been used for planetary radar before. This is a way to offer something new and different, while the capabilities of the two instruments – GBT and Goldstone – also would complement each other.”

But more importantly, since Goldstone is now “the only planetary radar game in town,” as Taylor described it, that means planetary radar in the US has a single point failure. The antennas of Goldstone Deep Space Communications Complex are busy 24 hours a day communicating with spacecraft around the Solar System.

“If Goldstone is down for whatever reason or if it’s not available because of its work with the DSN,” said Taylor, “having a radar transmitter on the GBT gives us more flexibility and redundancy.”

Taylor said there are several applications for the future of radar, from not only advancing our knowledge of objects in the Solar System and characterizing asteroids and comets, but also aiding in future robotic and crewed spaceflight.

The GBT worked with the Goldstone telescope to help confirm the success of NASA’s Double Asteroid Redirection Test (DART) mission in 2022, the first test to see if humans could successfully alter the trajectory of an asteroid. In a two-week campaign, the radio telescopes were able to track how the orbit of Dimorphos, the asteroid that was hit by DART, changed after the impact.

But the main goal ngRADAR is for is planetary defense.

“That will be one of the highest priority uses for the radar system, where we can track and characterize near earth-asteroids and comets to evaluate any hazard they might present to Earth in the future. Radar delivers very precise data that allows you to predict where these small bodies will be in the future. We can determine its size, how it rotates, what it might be made of, is it just a round ball, or does it look like a potato, or does it have a moon that you also must worry about.”

Building ngRADAR

As we discussed last week, a scaled-down prototype of ngRADAR at the GBT produced some of the highest resolution planetary radar images ever captured from Earth. Not only will the new full-scale system need to be built, but several changes will need to be made to the GBT. 

“This will be a pretty intensive infrastructure project,” Taylor explained. “We’ll have to build the transmitter and mount it onto the GBT. With the size and weight of the system, as well as the cooling systems that will be needed, extra structures will be needed to support all that.”

Taylor said the timeline for completion would depend on funding, but a reasonable goal is that in the next five years – perhaps by 2029-2030 – ngRADAR could be up and running.

But Taylor feels that ngRADAR will allow the GBT to come full circle.

“Some of the first science done with GBT was receiving radar signals when it was first inaugurated,” he said. “It’s been a receiver for radar for over 20 years but now we are trying to take the next step and have it be a transmitter as well.”

The 12th Large Hadron Collider Physics conference is taking place this week in Boston, and for the first time in a several years, I’ll be able to attend in person. I’ll post about it all week.

As part of the conference activities, I will be participating in a public event Thursday night at the Boston Public Library, a panel discussion entitled “Where the Universe and Humanity Collide.” The other panelists are Yale Professor Sarah Demers, a member of the ATLAS experiment at the Large Hadron Collider, and Dr. Katrina Miller, a particle physicis and a writer and essayist for the New York Times and other publications. We’ll be discussing the future of particle physics, talking about how we got into the field, and answering whatever questions the audience might have for us. If you’re in Boston, please consider attending!

Menstruation is occurring earlier and earlier in life for younger generations in the Western world, but researchers are puzzled as to why

Which is worse – clickbaity headlines for news articles that are factually correct, but may be playing up a sensational angle, or straight-up misinformation? It depends on what you mean by “worse”. A new study tries to address this information, with some interesting findings.

Misinformation is an increasingly important topic, one with far reaching implications for society. Our individual lives and our society is increasingly run on information. It is a critical resource, and the ability to evaluate and utilize information may be a determining factor in our quality of life. My favorite example remains Steve Jobs, because he is such a stark example. He was one of the richest people on the planet, with every physical resource at his disposal, and was a titan of an information industry. And yet he died prematurely of a potentially curable disease. He chose to delay mainstream treatment in order to pursue “natural” therapies that were ultimately worthless. We cannot know for sure what would have happened if he did not take this course, but his odds of survival would have been better.

At a societal level the most visible impact that our information ecosystems have deals with politics and public health. We are facing a rather dramatic decision regarding the next presidential election in the US, and this will ultimately be determined by how people are accessing and evaluating information. This has always been the case in a democracy, but I think most people alive today have not experienced a divergence of narrative and opinion as intense as we have today.

We also just when through the worst pandemic in a century, which brought into focus every issue dealing with misinformation. How do we deal with it in an age of social media? How do we balance the interests of making sure people get accurate health information so they can make informed choices, and freedom of speech and the value of open debate? There is no one correct answer, we just have to choose our tradeoffs.

But we can do research to at least inform our choices, to know what the tradeoffs are. That is where the new research comes in. Researchers at the MIT Sloan School of Management, publishing in Science, showed thousands of study participants 130 vaccine-related stories. They surveyed the subjects for their demographics, and asked them how the news story affected their intention to get vaccinated against COVID-19. They used this information to estimate the net effect of these vaccine-stories on society.

Their core findings are unsurprising. The more a news article suggested that vaccines could be harmful to a person’s health, the more they discouraged vaccination. Second, the more widespread the news article the more of an impact it had. Again – these are completely unsurprising findings. But then they calculated the net effect that a misleading clickbait headline of a factually correct article in the mainstream media would have vs terrible misinformation spread by social media. They found the clickbait headline would have 46 times a greater negative effect on vaccination rates than the social media misinformation.

The reason for this is because, even though the misleading mainstream article has a much lower negative impact on vaccine attitudes, it was read by far many more people. One mainstream article may be read by 54 million people, while a Facebook post flagged as misinformation may be read by only 0.3% as many people. Part of the reason this may be surprising is because we tend to intuitively underestimate the impact of very large numbers (we are just not wired to deal with such numbers). This comes up in many contexts. In medicine, we tend to intuitively focus on how typical a set of symptoms is for a disease, rather than the base rate (how common) that disease is. In reality, an atypical presentation of a common disease may be much more likely than a more typical presentation of an extremely rare disease.

The same is true with misinformation – we will intuitively give more consideration to the negative impact of an individual article rather than consider the numbers of people who may have read it, and have a hard time grasping the net effect of a small effect times millions of people.

How should we interpret these results? First, it does not mean that we should be ignoring misinformation on social media. In fact, I could argue that this research shows flagging misinformation and marginalizing it works. That was the whole point – to keep the number of people who see the extreme misinformation to a minimum.

But it also means that mainstream outlets have an extreme responsibility to be very careful with their headlines and the way they sensationalize important news. Headline writers are typically not the journalists themselves, and their whole job is to create eye-catching headlines. But responsible mainstream outlets should have editors who review and approve those headlines, and should filter out dangerous clickbait. It doesn’t matter that all the appropriate caveats are deep in the body of the article. The headlines themselves, and the opening paragraphs, need to capture an accurate gist of the story. It takes more work and consideration to create an intriguing headline that is also not misleading, but it’s worth the effort.

The Chang’e 6 moon lander touched down on 2 June and began collecting lunar rock for China’s second sample-return mission

Efforts to remove animal traps and discourage poaching in Vietnamese protected areas have been partly effective, but conservationists say other approaches are needed to safeguard threatened species

Dr. Pierre Kory and the pseudomous Substacker known as A Midwestern Doctor provide two more examples of how "anti-COVID" antivax has now become just antivax.

The post Yet another example of how “new school” anti-COVID vaccine antivaxxers have become just antivaxxers now first appeared on Science-Based Medicine.

After touching down on the moon’s far side, China’s Chang’e-6 lander is collecting samples to bring back to Earth — and sending back imagery documenting its mission.

Chang’e-6, which was launched May 3, went through weeks’ worth of in-space maneuvers that climaxed with its weekend landing in the moon’s South Pole-Aitken Basin region. The mission plan calls for the probe to collect samples of lunar soil and rock over the course of about two days, and then pack them up for the return trip.

If the operation is successful, Chang’e-6 would bring back the first fresh lunar samples ever collected on the moon’s far side — following up on the Chang’e-5 mission in 2020, which returned samples from the moon’s Earth-facing side.

The China National Space Administration said the lander used its onboard camera during its powered descent to detect obstacles autonomously and select a safe landing site. Chang’e-6 captured video imagery during the final phase of the lander’s descent and transmitted the views back to Earth. One video frame shows the shadow of the lander itself moments before touchdown.

Chang’e-6 is built to collect samples using a drill and a robotic arm. It’s also expected to gather scientific data about its surroundings using a radon detector, a negative-ion detector and a mini-rover. During surface operations, data and telemetry are being relayed between Chang’e-6 and Earth via China’s Queqiao-2 satellite.

Up to 2 kilograms (4.4 pounds) of lunar samples will be stowed inside the lander’s “ascender” stage. The rocket-powered ascender will then lift off from the surface and transfer the samples to the Chang’e-6 orbiter, which is currently in lunar orbit. Following the model set by Chang’e-5, the orbiter will head back toward Earth and release the sample capsule for atmospheric re-entry and touchdown in Inner Mongolia.

The moon’s south polar region is of particular interest because it’s thought to harbor reserves of water ice that could support lunar settlement. Studying fresh samples from the South Pole-Aitken Basin could help scientists and mission planners learn more about the region’s resources.

Chang’e-6 is the latest spacecraft in an international armada of moon landers — including Russia’s Luna 25, iSpace’s Hakuto-R and Astrobotic’s Peregrine, which were unsuccessful, plus more fruitful missions such as India’s Chandrayaan-3, Japan’s SLIM and Intuitive Machines’ Odysseus.

Coming attractions include NASA’s VIPER rover, which is currently due to be delivered to the moon late this year; and China’s Chang’e-7 mission, which features a hopping probe and is set for launch in 2026. Looking further ahead, China aims to send astronauts to the lunar surface by 2030 — not long after NASA’s Artemis 3 crewed lunar landing, currently scheduled for 2026.

This may not be Bill Maher’s funniest “bit” on his Real Time show, but it’s one of his best: a diatribe against the oppression of women in most majority-Islamic countries. He does get in a few humorous licks at American protesters who, he says, should be fighting Muslim gender apartheid instead of putting up tents and doing performative protests. And he’s right: half the population in countries like Saudi Arabia, Iran, Afghanistan and, yes, territories like Gaza, aren’t even close to having equal opportunity. This problem is sorely neglected by most Western feminists.

Not only are women surely restive under these restrictions, which are immoral because they treat people grossly unequally, but it would be much better for these societies to tap the potential of people with two X chromosomes.  It’s impossible for me to agree that maintaining gender apartheid (usually derived from bogus religious beliefs) is socially better than giving women equal opportunities. We know this is true from how Iran and Afghanistan used to be before they became fundamentalist Islamic countries, and how they are now, with veiled and monitored women agitating against the restrictions of the regimes. Do a Google Image search for “Women, Afghanistan, 1970s” and then compare it to a search for “Women, Afghanistan, 202os“. (See this post as well.)

Speaking of graduation, here are a video and some photos of convocation that took place yesterday. The expected protest by pro-Palestinian demonstrators did take place, but it wasn’t serious enough to disrupt the ceremony (see news report below), and so the seniors were able to have their Big Moment. Unfortunately, it drizzled and the ceremony was long, so many students and parents donned plastic ponchos that were provided for free. It often seems to rain on graduation day.

I have to admit that although I’ve witnessed many of these graduations, and hooded some of my students in them, I never get used to it. It’s a tremendous accomplishment (especially here, where the work is hard), and it’s heartwarming to see the students pose before and after the ceremony with their proud parents. (They used to post by Botany Pond, but it’s still under construction and fenced off.)

Because there were restrictions about being on campus, I wasn’t able to wander around freely to photograph, but here are a few things to give a flavor of the day.The police did let me film and take pictures before the ceremony and, from the door of my building, of the procession.

First a video of the beginning of the ceremony. The procession always begins with two bagpipers:

Miscellaneous shots:

Going through Hull Gate to the Quad:

Lots of selfies:

“Only the strong survive” on a mortarboard. Indeed. One of the tee-shirts they sell on campus says: “The University of Chicago: Hell does freeze over.”

There were students wearing keffiyehs, who probably participated in the subsequent walk-out during the ceremony (see below). I avoided taking photos of their faces to avoid implicating them in anything.

Foreground, my friend Eliza Ross, a pro-Israeli activist in the UChicago Maroons for Israel (along with Talia Elkin, Eliza brought charges against the Students for Justice in Palestine for disrupting a Jewish “event” in the Quad. SJP was given a slap on the wrist). I avoided showing her face, but look at her shoes:

She showed them off for me. The Hebrew says “Am Yisrael Chai”—”the people of Israel live.”

Here’s the whole set-up of the stage on the east side of the Quad, but before the students arrived. It’s a panoramic shot, so click to enlarge it.

An Instagram post from UChicago United for Palestine, alerting demonstrators to the graduation protest. I doubt that the masks are for safety against viruses; rather, they hide the identity of protestors so they can avoid punishment:

Here’s a Channel 7 news video of the pro-Palestinian protesters. There was not only a walkout during the ceremony itself, but also a group of non-University protesters to the west of the venue.  One of them, not affiliated with the University, was arrested for battery.  I tried to film the University protesters, clad in gowns and keffiyehs, as they walked out past my building, chanting “Free free Palestine”, but at that point the campus police wouldn’t let me take any pictures. I don’t think that’s a legal order, but I wasn’t about to buck the campus cops, who were clearly on high alert. Here’s a news report showing some of the protest:

As the Chicago Maroon reported in February (see my post on it here), a group of pro-Palestinian protestors who had violated University of Chicago rules by participating in sit-in in the admissions office were required to submit essays as part of their punishment.  I guess the point was to give students a chance to reflect on—and presumably repent about—their disruptive conduct. But the result was the opposite: the students doubled down in their activism and demonization of the University. Here are just two of several letters I reproduced:

“… I participated in the sit-in on November 9 because it is proven that my University has investments in weapons manufacturing companies, and I could not continue to attend classes and go about my day-to-day without thinking about how the institution I am a part of is facilitating the genocide and displacement of millions of Palestinian people. There is a long and honorable legacy of the sit-in protest being used to peacefully remind large institutions of the harm that they are causing people through their actions, a legacy that was taken up by students of UCUP. And if UChicago, a supposed stalwart of free speech, retaliates against students for taking up this form of protest and trying to communicate with administration at the University they themselves attend, what does that mean about free speech at this institution? Although I can understand the stress this may have placed on the Deans-on-Call, that was not intentional. The stress I experienced for the past several months knowing that my University is invested in companies that build bombs, and the stress that I experienced when the administration repeatedly refused to meet with us to discuss our demands, however, has been caused by the University…”

Sahar Punjwani, Class of 2024

. . . . and another:

“… The University of Chicago has, in my time here, taught me a lot. This sit-in, my arrest, and your office’s obligation to begin disciplinary proceedings against me, have taught me a lot as well that the University would rather criminalize and punish its students—those most committed not only to values of free expression but also noble pursuits of justice, equality, and liberation, and, as it has not passed my notice, most of whom are Black/Indigenous and students of color, and low-income—than meet with them and be transparent about its investments in arms companies.…

… I believe myself to be an excellent student and upstanding member of the UChicago community. I would never and have never sought to violate university policy. I sought to exercise my right to free expression, as established and championed by the Chicago Principles; and, after having attended the numerous quad tabling events, art builds, and rallies leading up to this sit-in, I felt moved to participate in this sit-in in an abundance of despair over my university’s failure to recognize its role in or even name the Israeli genocide in Gaza, where now over 22,000 Palestinians have been killed. Knowing that a Palestinian child was being killed every 10 minutes, knowing the school year in Palestine was canceled as all schools had been bombed or turned into refugee shelters, I could not continue to merely attend my classes. It is precisely because of my education that I participated in this sit-in; my education here has fostered a young mind that cannot turn a blind eye to the genocide that is taking place with my tuition money…”

Kelly Hui, Class of 2024, Student Marshal [JAC note: Hui,  was one of the four students whose degree was withheld by the University over their participation in the later Encampment, spurring a lot of protest on graduation day yesterday (see next post).

As you see, if the essays were meant to “reform” the students, they failed miserably.  The self-reflection that was supposed to teach students that “free speech” does not justify disruption (or at least disruption without punishment) led only to intensified demonization of the University and increased emphasis on its support of the so-called Israeli “genocide”. As you see, Hui, one of the students disciplined for participating in the sit-in, is now subject to disciplinary proceedings over participation in the later encampment. She is of course entitled to her views, but clearly the “essay” assignment didn’t change them.

A similar and risible attempt to get protestors to “self-educate” is the subject of Jesse Singal’s latest Substack post, dealing with protestors at New York University (NYU) who were asked to “self-educate” after illegally disrupting campus activities. But their “self-education assignment”, involving completing a complex series of exercis in a module, is even more ludicrous than was Chicago’s.

Click to read:

The background (Singal’s words are indented, and one quote he gives is doubly indented):

As you may have heard, there is a war between Israel and Hamas. As you may have also heard, there has been a surge of pro-Palestinian and/or anti-Israeli activism on many college campuses. While NYU didn’t get as much attention as its bigger and more Ivy-covered brother uptown, Columbia University, a group of students there were disciplined for their actions during protests.

Now that the dust has settled, the generous administrators at NYU have offered these students a chance to evade disciplinary action. As Ginia Bellafante reported in TheNew York Times a couple weeks ago:

While the university eventually moved to have the criminal charges against the students dropped, it initiated a disciplinary process against some of them (the university will not disclose how many) that seemed as if it had been conjured in the writers’ room of a dystopian sci-fi series. In order to return to the university, some students would be required to complete a 49-page set of readings and tasks — “modules” — known as the Ethos Integrity Series, geared at helping participants “make gains” in “moral reasoning” and “ethical decision making.” In a letter to the administration, Liam Murphy, a professor at the law school, called it “an intellectual embarrassment,” betraying the university’s mission as a training ground for independent thought and forcing students merely “to consume pages and pages of pablum.”

The Ethos Integrity Series was not the only command. Some students would be assigned a “reflection paper,” the details of which were laid out by the Office of Student Conduct. In it they would address several questions, among them: What are your values? Did the decision you made align with your personal values? What have you done or need still to do to make things right? Explicitly instructed not to “justify” their actions, the students were told to turn their papers in by May 29 in “12-point Times New Roman or similar font.”

Ben Burgis, who wrote a piece about all this in Jacobin that you should read, got a copy of the module, which he generously shared with me. You can read it here.

You should read Burgis’s piece but especially the copy of the module students were supposed to work through. The object, of course, was to convince the students, after reading and writing about morality and their own actions and values, that their illegal protests were immoral and wrong.  But as you see above, these protesters are already convinced that they were right, regardless of how much deep thought they’d devoted to their actions, and so these questions are a waste of time. NYU’s module includes, for example, a list of 42 “personal values” that you’re supposed to rank in order of importance. Here are the first ten:

Then there are a series of essays designed to promote self-reflection that leads to contrition. Here’s one:

Part 2: Essay about Sanctioned Action

In this essay, discuss the following questions using your responses from above to provide thorough reflection:

1. What was going on in your life leading up to and at the time of the sanctioned action? What influenced your decisions with regard to the sanctioned action?

2. Which of your values influenced your involvement in the situation that resulted in the sanctioned action, and which values were not considered in this situation? How so?

3. Why did you make the decisions you made regarding the action that lead to this sanction?

4. What were the outcomes of the situation and who was affected by those outcomes?

5. What have you learned (in general and about yourself) since the time of the situation that resulted in the sanctioned action?

Now think about how protesters are going to answer those questions. Here’s one more (it’s a LONG module):

9. What decision would a “Person of Character” make?

In fitting with a non-consequentialist perspective, Nash discusses asking what you would do if you were acting in character – meaning if you were acting in a manner to further your own personal, moral story that you are “attempting to live‟” (p. 15). Nash also suggests stepping into the shoes of a person who you respect and consider to be an ethical person. Identify a few of these people. The Persons of Character may be parents, professors, religious leaders, a co-worker or boss, etc. Look at the ethical dilemma from the perspective of one or two of these Moral Exemplars. What decision would these people make? Are these decisions a part of your set of options? If not, add them to the list.

You can image which “people of character” would be chosen!

The whole point is that this dumb series of modules is highly unlikely to change the minds of any protesters, particularly those who were so determined to act that they went beyond free, unsanction speech to violate university principles.  The module is not an “educational” experience in which students get to reflect on both sides of an issue. Rather, it’s designed to make students come to a predetermined conclusion—that their actions were wrong.

Singal also concludes that this exercise is fatuous, but favors leniency towards protesters, in the form of a warning for a first violation and punishment after subsequent ones. I agree with that, except that many of the protesters—like Hui mentioned above—were involved in multiple disruptions but were never given any initial warnings (Hui did participate in the essay exercise, which I suppose counts as a warning).

This stuck out to me as neatly exemplifying a certain very buzzword-heavy, bureaucracy-friendly approach to serious issues like ethics and social justice. My preference, at the end of the day, is toward leniency for nonviolent student protesters. If that means they have to fill out some idiotic form, fine. But why not do what Columbia did to some of the student protesters up there, and simply ask them to sign a document agreeing that henceforth, they will follow the student conduct guidelines? Then if they violate them again, no one can say they weren’t warned or didn’t have every opportunity to follow the rules.

This approach, on the other hand. . . it’s just debasing. It perverts the whole idea of moral inquiry and self-examination. It feels like what you get when the administrative class becomes too powerful within education.

Singal is right. Let students engage in civil disobedience if they feel strongly, and then impose the proper sanctions on them for doing so. (Until the war protests this year, accepting one’s punishment was an integral part of civil disobedience.)  But don’t try forcible education to change their views. That violates the entire purpose of a university, which is fostering free inquiry.

There was a time when maps of the Moon were created from telescopic observations and drawings. Indeed Sir Patrick Moore created maps of the Moon that were used during the historic Apollo landings. Now researchers have enhanced a technique to create accurate maps from existing satellite images. Their approach uses a technique called ‘shape-from-shading’ and involves analyzing shadows to estimate the features and shape of the terrain. Future lunar missions will be able to use the maps to identify hazards on the surface making them far safer. 

Researchers at the Brown University in Rhode Island have helped refine a process used to map the surface of the Moon making it more accurate than ever before. In their paper, published in the Planetary Science Journal and authored by Benjamin Boatwright and team details the enhancements to the mapping technique. It can generate detailed models of the Moon’s surface to highlight craters, ridges and slopes from composites of 2D images.

Highly detailed maps are of crucial importance to lunar missions and help the planners to identify the safest place to land. They can also use them to identify areas of particular interest that require further study enabling the whole mission to be far more efficient. Missions such as the Artemis project will benefit when it heads for the south pole of the Moon, an area which is not well mapped. High resolution maps of the area will aid the autonomous landing systems to avoid hazards.

Creating the maps is a time consuming job and is difficult to be accurate when lighting levels on target area are poor. The interpretation of shadows has been less than effective until now with the team addressing the issues. In their paper, the team explain how advanced computer algorithms can automate a lot of the process and improve the resolution of the generated models. Their new software gives lunar astronomers the necessary tools and information to create larger more detailed maps of the surface. 

To allow lunar scientists to create a map from images requires at least two images of the same area. Each image must be perfectly aligned with its counterpart so that features in one are in exactly the same place in the other. Until now, the technology has not been able to take multiple images of an area and create a perfect map. Boatwright said ‘We implemented an image alignment algorithm where it picks out features in one image and tries to find those same features in the other and then line them up, so that you’re not having to sit there manually tracing interest points across multiple images, which takes a lot of hours and brain power.’

Along with the image alignment algorithm, the researchers created quality control algorithms and filters to remove poor quality images from the alignment process. By only inputing good quality images to the process means the output will be of far higher quality. It is a similar model that astronomical imaging employs when processing multiple images through stacking and alignment techniques. 

To evaluate the accuracy of their work, the team compared the output from existing maps of the Moon to look for errors. To their delight, they found that maps created using their enhanced ‘shape-from-shading’ technique was more precise compared to those acquired during traditional techniques.

The post A New Way to Make Precise Maps of the Lunar Surface appeared first on Universe Today.

Six years after he announced a grand plan to fly around the moon with a crew of artists in SpaceX’s Starship rocket, Japanese billionaire Yusaku Maezawa said he was canceling the project due to delays in Starship’s development.

In a series of postings to the X social-media platform, Maezawa said he signed his contract with SpaceX “based on the assumption that dearMoon would launch by the end of 2023.”

“It’s a developmental project, so it is what it is, but it is still uncertain as to when Starship can launch,” he wrote. “I can’t plan my future in this situation, and I feel terrible making the crew members wait longer, hence the difficult decision to cancel at this point in time. I apologize to those who were excited for this project to happen.”

DearMoon crew member Yemi A.D., a Czech choreographer, talks about the mission’s cancellation.

After a selection process that attracted more than a million applicants, Maezawa named eight artists and communicators, plus two alternates, to the crew in late 2022. One of the chosen crew members was Tim Dodd, a science communicator and YouTube video creator who’s known as the “Everyday Astronaut.”

“Of course I’m extremely disappointed, having dreamt about this mission since I first heard about it in 2018 and even more for the last three years since the selection process started,” Dodd wrote in an extended posting to X.

Maezawa made his fortune by starting up what would become Zozo, Japan’s largest online clothing store. He sold most of his stake in the venture to Yahoo Japan in 2019 for around $2.3 billion. A fair amount of his riches has gone toward high-profile purchases, such as the $110.5 million acquisition of a painting by Jean-Michel Basquiat in 2017 and the estimated $80 million fare for a trip to the International Space Station in 2021.

The mega-launch system now known as Starship was at an early stage of development in 2018 when Maezawa struck a deal with SpaceX CEO Elon Musk to reserve a round-the-moon flight. The mission was envisioned as a roughly five-day trip that would give artists and performers on the level of Pablo Picasso and Michael Jackson the chance to experience space — and work that experience into their artistic creations.

The cost of the dearMoon project was never disclosed publicly, but at the time that the plan was revealed, Musk said Maezawa was providing a substantial deposit that “will have a material effect on paying for the cost of development” of the Starship system. Back then, Musk said the total development cost was on the order of $5 billion.

Developing and testing Starship has taken longer than Musk planned — which is par for the course when it comes to new types of spaceships. During the most recent Starship flight test, which took place in March, the rocket reached orbital altitude but broke up as it descended to a planned splashdown. Another flight test could take place as early as next week.

This isn’t the first time Maezawa has backtracked on his plans for spaceflight. In 2000, he pulled out of a reality-TV project that would have traced the selection of a female contestant to accompany him on a round-the-moon trip, presumably aboard Starship. Despite that precedent, the crew members for dearMoon said they were surprised by the cancellation of a trip they’d been so looking forward to.

“You didn’t ask us if we minded waiting or give us an option or discuss that you were thinking of canceling until you’d already made the decision,” Rhiannon Adam, an Irish-born photographic artist who was chosen for the crew, said in an X posting directed at Maezawa. “I can only speak for myself, but I’d have waited till it was ready.”

Another would-be spaceflier, night-sky photographer Brendan Hall, said in an online statement that “the cancellation of this mission was sudden, brief and unexpected.”

Dodd echoed that sentiment in his posting to X. “The one thing I have a hard time reconciling is the timeline,” he wrote. “Had I known that this could have ended within a year and a half of it being publicly announced, I would’ve never agreed to it. We had no prior knowledge of this possibility.”

Dodd said he remained optimistic about the long-term prospects for citizen spaceflight. “I still firmly believe that, within my lifetime, we will see missions like this happen, and while I will never be the first to do such a mission, it brings me great joy to know the future is bright and exciting,” he said.

It’s my day off, but I have to post at least one piece of news. This comes from Scholars for Peace in the Middle East, which is a pro-Israel organization whose reporting seems pretty accurate (there is lots of documentation, for example, in the article below). And that article, which you can access by clicking on the screenshot, is a longish summary of what happened in the last two months with encampments, arrests, punishments, capitulations, and so on.

If you’re interested in the campus protests, you’ll want to read the whole thing, but I’ll just post one excerpt about the concessions that universities made to protestors. Some are serious, others performative, but all were made to stop encampments and protestors.  Maybe I’m a grumpy old man, but I would stop illegal disruptions, like encampments, in their tracks using sanctions, and would be very loath to “bargain” with protestors who enacted illegal disruptions. (If protests are legal and student “demands” worth considering, it’s another matter. But institutional neutrality, at least a Chicago, would prohibit almost any concessions for protestors, as it did indeed.)

The excerpt:

At Northwestern University concessions included a promise to reveal its investments and to establish an investment advisory board with student participation which will advise trustees, student involvement in assessing university vendors, as well as two professorships and five scholarships for Palestinians, and a ‘Middle Eastern and North African’ residential unit.

Brown University promised protestors that after a student presentation divestment would be voted on by trustees. The students identified a number of aerospace and defense companies they alleged were complicit in “grave human rights violations” including Northrup Grumman, Boeing, and General Dynamics.

• At the University of Wisconsin-Milwaukee administrators agreed to permit anti-Israel students to present the case for divestment to trustees, called the situation a “plausible genocide,” condemned destruction in Gaza, and demanded a ceasefire. The chancellor later apologized for weighing in on “deeply complex geopolitical and historical issues.”
• The University of Washington agreed to demands from the “United Front for Palestinian Liberation” including student representation on a divestment committee, free tuition for 20 Gazan students, a faculty committee to examine academic boycotts, and a “Center for Scholarship of Palestine.”
• Within the University of California system the Berkeley administration agreed to a divestment task force and the chancellor called for a ‘permanent ceasefire.’ The Riverside administration agreed to similar terms and also terminated a variety of overseas programs including in Israel, which had been the target of long term pressure.
• Goldsmiths College agreed to student demands after a five week occupation, including scholarships for Palestinian students, a review of investment policy, and renaming a theater in honor of Palestinian journalist Shireen Abu Akleh.
• Trinity University announced “divestment from equity investments in Israeli companies that have activities in the Occupied Palestinian Territory and appear on the UN Blacklist in this regard.” It will also bring in Gazan students and faculty and review student exchange programs. The decision came after protestors blockaded the exhibit of the Book of Kells which earns the school some €350,000 a week during the summer.
• Union Theological Seminary announced that it would “identify all investments, both domestic and global, that support and profit from the present killing of innocent civilians in Palestine” in order to “withdraw support from companies profiting from the war.”
• The New School for Social Research agreed to hold a divestment vote in June “from industries implicated in military and police violence in Gaza and the West Bank, and all global militarized conflict such as companies or subsidiaries involved in weapons manufacturing, military supplies and equipment, military communication, and public surveillance technology.”
• Bard College announced an agreement with protestors that included disclosure of investments, strengthening ties with a branch campus in East Jerusalem, and “support of appropriate challenges — political, social, and legal— to Executive Order 157,” banning investments in institutions or companies that boycott Israel.

The most extreme example of concessions to students came at Sonoma State University where the president, Mike Lee, agreed to fully divest from Israel, permit an SJP ‘advisory council’ to oversee the agreement with protestors, introduce ’Palestine’ and a ‘Palestine Studies’ program, and to ban all Israel programs. Cal State administrators, however, quickly accused Lee of “insubordination” and forced his retraction and then retirement. Acting President Nathan Evans then met with protestors after they disrupted commencement.

Many of these colleges, in their concessionary pronouncements, violated any principle of institutional neutrality. These violations include terminating programs to Israel, calling for “permanent ceasefire,” and declaring that they’d divest.  Preferential admission of students from Gaza is surely illegal under Title IV (see below), as is preferential hiring of scholars from Gaza, a Title VI violation involving employment discrimination.

My view is that when the dust settles after graduation, the protesters will have accomplished very little with their demands, and certainly will not have done anything to influence the war.  The problem is that the Gaza issue will remain alive for some time, even after Israel destroys Hamas, and so the whole thing is likely to start up again in the fall, turning colleges once more into Social Justice Factories instead of places of learning.

Here’s a few words from the article about where I was a few weeks ago, and where Maarten Boudry tells me things are even worse than depicted below.

The most significant and real Israel boycotts have emerged in the Netherlands. Ghent University [JAC: Not in the Netherlands!] severed ties with three Israeli research institutions on the grounds they are “problematic according to the Ghent University human rights test” while Leiden University has put exchange programs with Israeli universities on hold and “will assess all our current ties with Israeli institutions and joint research projects.” The university also stated it will also not admit Israeli students from Tel Aviv University or Hebrew University “until after an evaluation.”

And the summary of just this section (the whole article is much longer):

Overall the universities appear to have provided a mixture of performative and real concessions. Some appear to be simply delaying tactics, postponing confrontations until the fall semester. Funding Gazan students and creating ‘Palestine studies’ centers, however, guarantees future campus radicalization by introducing anti-Israel extremists. The privileged admission of Palestinian students also appears to be in violation of Title IV of the Higher Education Act while the creation of residential and Muslim-only spaces reinforces campus identity politics.

Observers also note that most institutions invest in index funds rather than individual stocks, making removal of specific companies difficult or impossible. Nor is it assured that even individual institutions with less complex finances could divest. William College’s decision not to divest and not to embrace ‘environmental, social, and governance’ (ESG) guidelines was specifically explained as a function of the inherent practical and moral difficulty involved. State anti-BDS laws also complicate divestment.

It’s been a very long academic year. . . .

Now from Cole and Marmalade we have a very rare “Unicorn Cat”. Click to read (see also Cheezburger.com and reddit)

The latest rare unicorn cat, a cat that almost doesn’t look real, is capturing lots of hearts online. Is this cat for real? Or is it an AI image? Who can tell anymore? It’s rapidly getting harder to say what’s artificial intelligence versus authentic these days. We see people believing in fakes so much, so it’s (unfortunately) a legitimate question in 2024.

However, this unicorn’s human promises he’s very much real, supplying more images.

Meet Bruce, a kitty so unusual that his mama has had to tell folks on Reddit, “He is real.”

According to the post, Bruce is a Minuet, a cross between a Persian and a Munchkin with shorter legs. But if so, he’s unlike any cat we’ve seen.

As you can see, Bruce appears to be Tuxie on his face but with the palest silvery blue eyes. That alone is unusual as most tuxedo adults will have a pale greenish or yellow eye color. Unfortunately, it suggests Bruce might be the result of the breeder’s efforts to produce cats with the “Dominant Blue Eye” trait. 

All photos from u/No_Secretary8854

. . . . Considering that it looks like Bruce is a combination of two cats, this unicorn kitty may be a genetic chimera. These cats, like the famous Venus, the two-faced cat, may have different eye colors and appear as two felines split right down the middle to make one animal!

Put very simply, a chimera has at least two different sets of DNA after the fusion of fertilized eggs or zygotes. They can sometimes be both male and female at once, leading people to speculate about Bruce’s gender, which could factually be ambiguous and nonbinary. Since the kitty seems to show the tortie or calico color (almost always female), it’s an added level of oddity that the name suggests he’s fully male too. It’s even rarer!

Whatever the case, Bruce is adorable and lovable and behaves like any cat being handled at the vet. Thus, we must acknowledge that the colors, however pretty or rare, don’t really matter at all.

But they do matter because these colors get the cat a lot of attention! Still, why don’t they say something about the secondary sexual characteristic of the cat? Does it have male or female genitals, for one thing?

From Meowingtons.com we hear about cats that once delivered mail in Belgium. Bad idea! Click to read:

 

An excerpt:

Once upon a time in the Belgian town of Liège, the postal system was taken over, briefly, by cats.

, , , But as intelligent and skilled as cats are, we know that even our feline friends have their limitations. Which is why when a city in 1870s Belgium decided to use cats to deliver mail, a system that relies on a timeline that doesn’t exactly suit the ideal 17-hour sleep schedule of a cay … well, it should come as no surprise that it was relatively short-lived.

Nevertheless, in the 1870s, the city of Liège, Belgium hired a grand 37 cats to deliver mail. Messages were to be tied around the cats’ necks in waterproof bags to prevent any damage to the letters. The idea was to allow the citizens of Liège and surrounding villages to easily communicate with each other.

“Unless the criminal class of dogs undertakes to waylay and rob the mail-cats, the messages will be delivered with rapidity and safety,” The New York Times reported. One particularly dedicated feline delivered his letter safe and sound in less than five hours! However, the other felines took up to a day to deliver mail to their own homes, preferring a leisurely stroll and maybe a saucer of milk along the way.

Sadly, there are no photos of this horrible idea, but the BBC does have a section on Post Office Cats in its “working cats” post (more later). Excerpts:

In 1868 three cats were formally employed as mousers at the Money Order Office in London. They were “paid” a wage of one shilling a week – which went towards their upkeep – and were given a six-month probationary period.

They obviously did their job efficiently as in 1873 they were awarded an increase of 6d a week. The official use of cats soon spread to other post offices.

According to the Postal Museum, the most popular cat of all was Tibs. Born in November 1950, at his biggest he weighed 23lbs (10.4kg) and lived in the Post Office headquarters’ refreshment club in the basement of the building in central London. During his 14 years’ service he kept the building rodent-free.

Wikipedia has an article on “Tibs the Great” with a photo and more information:

Tibs worked at Post Office Headquarters in London for 14 years, and was officially employed and paid 2s 6d per week. He worked in the basement. He was cared for by Alf Talbut, cleaner at the church of St. Martin’s Le Grand, who had also owned his mother, Minnie.[4] During his 14 years, Tibs kept the Post Office headquarters completely free of mice.[1]

In 1952, there was “public outrage” that the cats had not had a pay rise since 1873, and the next year there was a question in the House of Commons, asking the Assistant Postmaster-General, David Gammans, “when the allowance payable for the maintenance of cats in his department was last raised?”[1]

Tibs died in December 1964; he had been suffering from oral cancer. He received obituaries in several newspapers. By the time of his death he had grown to 23 lb (10 kg) in weight, probably due to living in one of the staff dining rooms, rather than from eating rats.

. . . The last cat employed at Post Office headquarters was Blackie, who died in 1984, which coincided with cloth sacks being replaced with rodent-resistant plastic sacks.[2]

Here’s Tibs’s obituary printed in the Post Office Magazine:

Also from Cole and Marmalade: Karma for an animal abuser (click to read):

Being cruel to animals or other people always comes back to bite the person doing the abuse. But so often, it seems Karma has extreme patience, and justice is not swift enough for our liking.

Well, for a couple of people who were abusive to animals, the trouble that came for them is all they may ever be remembered for. Over 75 years later, their stories are remembered as anecdotes shared all over the world. 

It’s amazing to think that this story from 1949 in France is still circulating around the world today. It’s all about the swift justice that came after a man named Henri Villette tried to drown a kitten. Who could have sympathy for what became of him?

Here are some news stories, with one in French:

Today, people remember Villette only as a sort of fable that tells a moral. Most versions are attributed to the Associated Press and appeared in newspapers in the United States, like the Gettysburg Times and the Ironwood Daily Globe from Michigan and the Des Moines Tribune from Iowa in 1949. The Daily Mirror in Sydney, Australia also shared the story as well as the Singapore Free Press.

More:

The story also appeared in TIME magazine, dating to October 3, 1949, with more interesting details.

“Cool and confident in his superior strength and wisdom one day last week, Henri Villette, a 67-year-old barrelmaker of Alencon, clapped an unwanted kitten into a musette bag and set out for the Sarthe River to drown it. On the river’s bank he slipped and fell. The kitten crawled to safety. Henri’s drowned body was found later by local firemen,” the story states.

There’s also a story of an abused d*g who was thrown into a well by an odious man, but the d*g lived seven months in the well, eating corpses thrown down by other people, before it was rescued. Here it is, but brush up on your French!

Lagnaiappe: a physics cat (see here):

Here’s the story from Atlas Obscura, complete with a reprint of the paper, signed by both human and cat authors:

Jack H. Hetherington was a professor of physics at Michigan State University in 1975, when he finished what would become an influential and often-cited physics paper. The academic writing, entitled Two-, Three-, and Four-Atom Exchange Effects in bcc 3He, was an in-depth exploration of atomic behavior at different temperatures. It would have flown over the heads of most lay people, not to mention cats.

He was all set to send it to Physical Review Letters, which today describes itself as “the world’s premier physics letter journal.” However, before he dispatched it, Hetherington gave the paper to a colleague to get one last set of eyes on the piece. This is when he ran into a strange problem. Hetherington had used the royal “we” throughout the paper. As his colleague pointed out, Physical Review Letters generally only published papers using plural pronouns and adjectives like “we” and “our” if the paper had multiple authors.

. . .Hetherington wrote that after giving the issue “an evening’s thought,” he decided the paper was so good that it required rapid publishing. Unwilling to go back and replace the plural voice in the document, he did the next best thing and just added a second author: his Siamese cat, Chester. Of course just listing “Chester” as a co-author probably wouldn’t fly, so he invented the name F.D.C. Willard. The “F.D.C.” stood for “Felix Domesticus, Chester.” Willard had been the name of Chester’s father.

Portraying F.D.C. Willard as one of his colleagues at Michigan State, Hetherington submitted his paper, and it was published in issue 35 of Physical Review Letters.

Today we have part 2 of ecologist Susan Harrison‘s visit to the Dry Tortugas, with today’s photos comprising seabirds. Susan’s captions are indented, and you can enlarge the photos by clicking on them. Part 1 is here, and I’ll add the two paragraphs of her introduction below.

Dry Tortugas seabird colonies

Introduction to last part:

The Dry Tortugas are the westernmost of the Florida Keys, lying just over 100 miles from the mainland. These tiny sandy islands, or cays, are uninhabited by people but essential to bird life.  They support  breeding colonies of some unusual seabirds, and they are the North American landfall for many spring-migrating songbirds.

Dry Tortugas National Park was created to protect these birds, and human visitors can go to only one island:  Garden Cay, which supports Fort Jefferson, a huge crumbling installation begun in 1846 and abandoned in 1906.  The fort saw use as a Civil War prison, a quarantine, and a coaling station, but its war-worn look is an illusion.  Somehow the engineers of the day did not realize that iron fittings exposed to salt water would expand and tear apart its brick walls.

And today’s post:

In an earlier post I showed the migratory birds that use the low sandy islands (cays) of the Dry Tortugas chain as a stopover en route to North America.  Today’s post shows another set of birds that rely on the Dry Tortugas: several species of tropical pelagic seabirds that spend most of their lives at sea, and nest on the cays where there are no predatory mammals.

Fort Jefferson, the epicenter of Dry Tortugas National Park, with the rest of Garden Cay on the right:

In April, Magnificent Frigatebirds (Fregata magnificens) circled constantly above the fort.  Females have white chests, males are dark with red throat pouches, and juveniles have white heads.

Magnificent Frigatebirds:

The Magnificent Frigatebird breeding colony lies on some tiny islands next to Garden Cay.  Their nesting trees were damaged by recent hurricanes.

Thousands of Sooty Terns (Onychoprion fuscatus) and Brown Noddies (Anous stolidus) nest on the sandy flats next to the fort, together with a few of their rarer cousins, the Bridled Tern (Onchyoprion anaethetus) and Black Noddy (Anous minutus).   A few miles away, a very small cay supports a colony of Brown Boobies (Sula leucogaster) and Masked Boobies (Sula dactylatra).

*According to the NYT, Trump went bananas after his conviction yesterday, but what else did you expect given the verdict?

As America began to absorb on Friday the conviction of Donald J. Trump, a first for a U.S. president, he criticized the criminal case and attacked the judge who oversaw his trial.

Mr. Trump, in a rambling and misleading 33-minute speech, derided the trial as “rigged” and made numerous false statements about what had taken place in court. His remarks came after he was found guilty on Thursday of all 34 felony counts of falsifying records to cover up a sex scandal that threatened to derail his 2016 presidential campaign.

Mr. Trump, who said he would appeal the verdict, continued to attack people who testified against him in the seven-week trial, specifically his former fixer, Michael D. Cohen, the star witness for the prosecution. He also admitted that he had gotten “very upset” with his lawyers.

He called the judge, Juan M. Merchan, the “devil.”

. . . At Trump Tower on Friday, Mr. Trump reprised his usual campaign attacks on immigrants and made numerous false representations about U.S. border policies under President Biden. He falsely claimed that American children couldn’t play Little League Baseball games anymore because undocumented immigrants were setting up too many tents.

Well, I’ll venture to predict (though I won’t be able to prove it) that Trump’s conviction will hurt his election chances in November. He is a convicted felon, and among the undecided voters that could make a difference. Plus he’s a bull-goose looney.

*Democratic Senator Tim Manchin from West Virginia, always a renegade, has changed his party affiliation to “independent”.  Last winter he announced he wouldn’t be running again, but this suggests he will. And, if he’s elected, it means the Democrats will be even less able than before to count on his vote.

Democratic Sen. Joe Manchin III of West Virginia announced Friday that he has changed his party registration to independent, fueling speculation he could run for office again in November after announcing his retirement last year.

“My commitment to do everything I can to bring our country together has led me to register as an independent with no party affiliation,” Manchin wrote on X.

Manchin did not immediately say anything about his political plans. But the move allows him to possibly reconsider his plan to not seek reelection — or to run for governor, a job he previously held.

Aug. 1 is the deadline for independent candidates to file for office in West Virginia. Manchin was facing a Saturday deadline to register as an independent and still have a chance to file as an independent candidate this election.

The centrist senator announced in November 2023 that he would not run for another term, handing Republicans a likely pickup seat in solidly red West Virginia. The GOP nominee for the seat is the state’s governor, Jim Justice.

. . .For months, Manchin flirted with running for president as an independent or third-party candidate, worrying Democrats who anticipated a close rematch between President Biden and former president Donald Trump. But Manchin announced in February that he would “not be involved in a presidential run” this year.

Speculation has picked up in recent weeks that Manchin may be mulling a return to the governor’s office, though he reportedly said this week he would not enter the race. He said he is supporting the Democratic nominee, Steve Williams.

If Manchin decides to run for Senate again, he could have a fighting chance in a race that otherwise favors the GOP. CNN reported in March that Senate Majority Leader Charles E. Schumer (D-N.Y.) has talked with Manchin about running for reelection as an independent. At the time, Manchin said he did not expect to do so.

In fact, the guy is so much of a renegade that we don’t know what he’s going to do. All we can guess is that he’s going to run for something. 

*The war in Gaza, now that the IDF is operating around Rafah, has become a real mess, as the three-man war cabinet has become split about what to do. The dissent involves whether to prioritize defeating Hamas or getting the hostages released (I suspect that a lot of them are actually dead.)

As the fighting continues, the debate in Israel over the necessary next steps is becoming more intense. The issue has not set the ruling coalition against all or part of the public. Rather, the divisions bisect the government and have split the three-man war cabinet consisting of Prime Minister Benjamin Netanyahu, Minister of Defense Yoav Gallant and Chief of the General Staff Benny Ganz. The matter of who wins this debate, along with the issue of western pressure on Israel, are likely to determine the outcome of the war.

Former Chief of Staff Gadi Eizenkot, an observer in the war cabinet who is closely aligned with Gantz, was, according to Israel’s Channel 12 News channel, reported to have told the Knesset’s foreign affairs and defence committee last week that Israel should pause its Rafah operation in order to conclude an agreement for the release of the 128 Israeli hostages remaining in Hamas captivity.

While Eizenkot clarified in his statement that Israel would be able to recommence the fighting at a later date, this seems to be at odds with reality. The position of the Gaza Hamas leadership throughout has been that a hostage deal was possible only if Israel were to agree to a long-term cessation of the war. So if Israel really wishes to go down the route of prioritising the release of hostages, the cost is almost certainly an admission of defeat in the eight month-long military campaign in Gaza. Defeat in this context means the cessation of hostilities without the destruction of the Hamas ruling authority in Gaza.

. . .Among those in Israel who seek an early end of the war and a central emphasis on getting hostages released, this reality is accepted, rather than blurred. Thus Zehava Golan, a former leader of the left wing Meretz party, stated the matter plainly in a column in the Haaretz newspaper on Wednesday: ‘We need to bring back the hostages via a deal now, establish a state commission of inquiry to look into the events of 7 October and the conduct of this war, and stop the war itself,’ she wrote.

On the other side, Netanyahu and his allies reject the Hamas demand for an end to the war, seeing this (accurately) as representing surrender to the Islamist movement. Netanyahu, however, in a fudge of his own, was reported to have indignantly rejected the notion that he and those around him were refusing to give the team negotiating on the issue of the hostages a mandate that could lead to a successful agreement. But given that Hamas is clearly and openly demanding the end of the war as a price for agreement, it follows logically that any negotiating mandate that clearly rejects any such outcome does in fact then undermine the chance for a successful agreement on the hostages.

The reason for both Netanyahu and Eizenkot’s obfuscations is that the Israeli mainstream debate is not yet able to openly confront the horrific nature of the strategic position into which the Hamas leadership has placed it. Namely that it must either concede defeat to the Gaza Islamists, or follow a path that may well seal the fate of the 128 remaining Israeli hostages in Gaza.

This is a horrible dilemma; you lose the hostages or risk losing your country. What should the war cabinet do? They’ll probably continue going after Rafah and leave the hostages as a secondary consideration, for Netanyahu runs the war cabinet and a majority of Israelis want the IDF to persist in Rafah.  The cold-hearted calculus might say that if you let Hamas persist in power and rescue all the hostages (Remember that we don’t know how many are still alive, and Hamas won’t say), in the long run more Israelis will die from terrorism than lives will be saved by recouping the hostages. But it’s still a horrible thing to do—making a calculus of lives. But this is an existential war for Israel, and those of us who pay attention now have to force ourselves to just sit back and try to disengage. After all, there’s little we can do.

*As always, I’ll steal three items from Nellie Bowles’s weekly summary of the news, called this week “The Trial of the Century of the Week“. Actually, I’ll steal four this week so I can slip in the loon Candace Owens:

→ What Chinese propaganda? A new poll of young people by the firm Blueprint finds that a huge percentage of them think America is basically hell. Specifically, they see it as “a dying empire led by bad people.” Also: they need a ride to lacrosse practice. Some 51 percent agreed that the U.S. political system “doesn’t work for people like me,” and 64 percent supported the idea that “America is in decline.” Only 26 percent think it matters who wins the next election. Now, I’m not going to say this can be traced back entirely to the fact that the youth have hooked their eyes to a Chinese propaganda machine, but it does raise the question. Like, I’m not happy about our presidential choices either, but I do think things are different if one or the other is chosen. Does that make me a patriot?

→ Candace Owens going full crazy: Our favorite right-wing influencer is not antisemitic but is just obsessed with the Jews, specifically tracking how various evil acts and empires in history can all be traced to Jewish influence. This is the vibe these days: “I will grant you that Stalin’s ancestry is still hotly debated. My Georgian friend tells me that his real name ‘Djugashivilli’ literally translates into ‘child of Judah’ and that everyone in Georgia knows he was Jewish but that is hearsay and hardly admissible as a fact. What we do know for a fact is that Stalin spoke Yiddish and his three wives were all Jews.” Hmm. Candace’s rantings—to her more than 5 million followers on Twitter/X alone—continue.  [See this refutation of Owen’s tweet “the vibe”.]

Here are a few tweets I found by Candace Owens (click to go to tweet).  She has 5.1 MILLION followers.

→ The polling problem is Biden, not Dems: Democratic Senate candidates in swing states are doing great, according to a new poll from the quite reliable Cook Political Report. While Biden is projected to lose to Trump in the noted states, the Dems’ Senate candidates are doing extremely well. Many are differentiating themselves from the Biden administration on unpopular-for-Dems issues like the border, in that they’re arguing they don’t want a fully open border. They’re playing up their pro-choice bona fides and displaying their youth and virility through confident, youthful exhibitions like cheering in jerseys at a soccer game. Makes you wonder: If Biden had stepped aside for another candidate, would Trump be in the lead right now? The poll results image is best on desktop, unfortunately for my cell phone readers:

→ Campus update: Harvard’s Students for Justice in Palestine group called for an escalation of “intifada,” which historically means attacks on Jews: “Escalate protests to an open intifada in every capital and city.” Columbia’s chapter of the same influential club explained: “Supporting a 2 state solution is an inherently zionist position as zionism means that you believe in Israel’s right to exist.” And Harvard’s commencement speaker, journalist Maria A. Ressa, defended herself against allegations of antisemitism with more antisemitism in her speech: “I was. . . called antisemitic by power and money because they want power and money.” Well, that clears that one up.

And then all of a sudden, Harvard decided to slow down on weighing in. They’re out of the condemnation game, they say, mostly, at least right now, maybe not forever.

*In the latest Weekly Dish, “The consistency of their genius,” Andrew Sullivan leaves the Trump conviction to one side and analyzes two pop-culture phenomena that he admires, the musical group The Pet Shop boys and the television show “South Park.”

In fact, I want to celebrate what still rocks my world: the staggeringly consistent, supremely intelligent, and self-assured genius of two unique duos still powering forward in two different worlds: South Park and Pet Shop Boys.

That those brand names are more recognizable than their creators — Matt Stone and Trey Parker, Neil Tennant and Chris Lowe — tells you something of what they have in common: a commitment to their own unique creativity, rather than their fame, and the discipline and grit to explore it for decades. Anti-celebrities, in their time but never of it, perfectionist but unafraid of failure, these two duos are proof, it seems to me, that a democratic culture, even one as decadent as ours, can still spawn excellence and intelligence, spanning high and low, and generating what I can only call joy.

South Park is going into its 27th season. And it has rarely been better. (I simply can’t believe so many people I meet say they haven’t watched in years. You’ve been missing out!) The new special on obesity — a deft masterclass of social commentary — has a brutal takedown of suburban white women jonesing for doses of Ozempic like meth-heads; a definitive — and musical! — digression into the insanity of the American healthcare system; pure, character-driven humor in a figure like Randy Marsh — a far subtler parody of the average American male than Homer Simpson; and, of course, Eric Cartman — the “big-boned” fat-ass kid whose capacity for pure evil was first truly captured in the epic “Scott Tenorman Must Die.”

You can read books on Ozempic, scan op-eds, absorb TikToks, and even listen to the Dishcast! — but nothing out there captures every single possible social and medical and psychological wrinkle of this new drug than this hour of crude cartoons. Yes, there are fart jokes. There are always fart jokes. But fart jokes amid a sophisticated and deeply informed parody of insurance companies? Or, in other episodes, toilet humor guiding us through the cowardice of Disney, the dopey vanity of Kanye, the wokification of Hollywood, the exploitation of black college athletes, the evil of cable companies, the hollowness of hate-crime laws, the creepiness of Christian rock, or the money-making behind legal weed? Only South Park pulls this off. Only South Park gets away with all of it.

It’s a 1990s high-low formula at root, sophisticated cultural and political knowingness married to crude cartoons, silly accents, m’kay, and a talking Christmas turd, Mr Hankey. Generationally, it really marked a moment when merging these two worlds seemed the most creative option — not an abandonment of seriousness, but the attachment of a humane levity to it. South Park can be brutal, but it is never cruel. Unless you’re Barbra Streisand or Bono. And virtually every character (even Eric) is redeemable. Except Meghan Markle.

I don’t get cable t.v., not because I can’t afford it pecuniarily but because I can’t afford it timewise or mentally: there are too many books to read. But when I read a paean like the one above, it does make me sad that I don’t watch the show.  The episodes I’ve seen I have liked, but isnt that true of a lot of television shows.   I can afford to get hooked on new shows when there are places to see and books to read.  (This, of course, is just my subjective preferences and I don’t fault anyone who stays glued to the t.v. Wait a minute: yes I do. I don’t fault people who are selective in what t.v. they watch.

Meanwhile in Dobrzyn, Hili is down by the Vistula River, having walkies with Malgorzata and Andrzej:

Hili: May we return home? A: Why? Hili: There is something alarming in the air. In Polish: Hili:: Czy możemy wrócić do domu? Ja: Dlaczego? Hili: Jest coś niepokojącego w powietrzu.

From Luana. The free speech that was affirmed was that of the National Rifle Association, and though I dislike them intensely, I also think that their free speech rights must be preserved regardless of how odious they are. From CBS News:

The Supreme Court on Thursday ruled in favor of the National Rifle Association in a dispute over whether its free speech rights were violated when the top financial regulator for New York state pushed banks and insurance companies to sever ties with the gun rights group.

The court said in a unanimous opinion written by Justice Sonia Sotomayor that the NRA “plausibly alleged” that the New York regulator violated the First Amendment by coercing regulated entities to end their business relationships with the NRA in order to “punish or suppress” the group’s pro-gun rights advocacy.

“The critical takeaway is that the First Amendment prohibits government officials from wielding their power selectively to punish or suppress speech, directly or (as alleged here) through private intermediaries,” Sotomayor wrote.

This morning, the Supreme Court unanimously reaffirmed a foundational First Amendment principle: “A government official cannot coerce a private party to punish or suppress disfavored speech on her behalf.”

So much of what we hear about China and Russia today likens the relationship between these two autocracies and the West to a “rivalry” or a “great-power competition.” Some might consider it alarmist to say we are in the midst of a second Cold War, but that may be the only responsible way to describe today’s state of affairs.

What’s more, we have come a long way from Mao Zedong’s infamous observation that “political power grows out of the barrel of a gun.” Now we live in an age more aptly described by Vladimir Putin’s cryptic prophecy that “artificial intelligence is the future not only of Russia, but of all mankind, and whoever becomes the leader in this sphere will become ruler of the world.”

George S. Takach’s incisive and meticulously researched new volume, Cold War 2.0, is the book we need to thoroughly understand these frightening and perilous times. In the geopolitical sphere, there are no more pressing issues than the appalling mechanizations of a surveillance state in China, Russia’s brazen attempt to assert its autocratic model in Ukraine, and China’s increasingly likely plans to do the same in Taiwan.

But the key here, Takach argues, is that our new Cold War is not only ideological but technological: the side that prevails in Cold War 2.0 will be the one that bests the other in mastering the greatest innovations of our time. Artificial intelligence sits in our pockets every day—but what about AI that coordinates military operations and missile defense systems? Or the highly sophisticated semiconductor chips and quantum computers that power those missiles and a host of other weapons? And, where recently we have seen remarkable feats of bio-engineering to produce vaccines at record speed, shouldn’t we be concerned how catastrophic it would be if bio-engineering were co-opted for nefarious purposes?

Takach thoroughly examines how each of these innovations will shape the tension between democracy and autocracy, and how each will play a central role in this second Cold War. Finally, he crafts a precise blueprint for how Western democracies should handle these innovations to respond to the looming threat of autocracy—and ultimately prevail over it.

George S. Takach holds a bachelor’s degree in history, political economy, and philosophy from the University of Toronto; a graduate degree from the Norman Paterson School of International Affairs at Carleton University; and a law degree from the University of Toronto. For forty years, he practiced technology law at McCarthy Tétrault, Canada’s premier law firm. He has written three books on technology law/tech commercial subjects. Cold War 2.0: Artificial Intelligence in the New Battle between China, Russia, and America is his first book for a general audience. He lives in Toronto.

Shermer and Takach discuss:

• Mao Zedong, 1927: “Political Power grows out of the barrel of a gun.”
• Vladimir Putin: “artificial intelligence is the future not only of Russia, but of all mankind, and whoever becomes the leader in this sphere will become ruler of the world.”
• What is AI and what will it be able to do in the coming decades?
• China’s surveillance state
• Russia and Ukraine
• Cold War 1.0: Autocracy, Democracy and Technology
• Cold War 2.0: AI and Autocracy and Democracy
• semiconductor chip supremacy
• quantum computing
• biotechnology
• China and Taiwan
• How China’s invasion of Taiwan is likely to unfold, and what the U.S. can do about it.
