Schantz on Origins of Special Relativity

Hans G. Schantz posts a discussion of sources for Einstein and relativity:
Perhaps the evidence is only circumstantial that Einstein plagiarized relativity, but should we extend the benefit of the doubt to one who has clearly hidden the evidence?

By failing to note his influencers and predecessors, like PoincarĂ© and Hendrik Antoon Lorentz (1853–1928), Einstein created lasting disputes about the extent to which his thinking was original and how much it was derivative. ... The point is, they should not have had to do this. Einstein exhibited a shockingly cavalier attitude toward citing references throughout his career.

There is some question about whether Einstein saw Lorentz's 1904 paper and Poincare's 1905 paper on relativity. But it is pretty clear that he read their earlier papers.

In particular, in 1905 Einstein got the constant speed of light and the Lorentz transformations from Lorentz, and he got clock synchronization of the relativity principle from Poincare. He only got the crucial idea of four-dimensional Minkowski space from Minkowski several years later. It is not clear that he ever accepted the geometrical interpretation that is common in textbooks today.

How Colleges got Politicized

English professor Michael W. Clune writes:
We Asked for It
The politicization of research, hiring, and teaching made professors sitting ducks.

Over the past 10 years, I have watched in horror as academe set itself up for the existential crisis that has now arrived. Starting around 2014, many disciplines — including my own, English — changed their mission. Professors began to see the traditional values and methods of their fields — such as the careful weighing of evidence and the commitment to shared standards of reasoned argument — as complicit in histories of oppression. As a result, many professors and fields began to reframe their work as a kind of political activism.

In reading articles and book manuscripts for peer review, or in reviewing files when conducting faculty job searches, I found that nearly every scholar now justifies their work in political terms. This interpretation of a novel or poem, that historical intervention, is valuable because it will contribute to the achievement of progressive political goals. Nor was this change limited to the humanities. Venerable scientific journals — such as Nature — now explicitly endorse political candidates; computer-science and math departments present their work as advancing social justice. Claims in academic arguments are routinely judged in terms of their likely political effects.

The costs of explicitly tying the academic enterprise to partisan politics in a democracy were eminently foreseeable and are now coming into sharp focus. Public opinion of higher education is at an all-time low. The incoming Trump administration plans to use the accreditation process to end the politicization of higher education — and to tax and fine institutions up to “100 percent” of their endowment. I believe these threats are serious because of a simple political calculation of my own: If Trump announced that he was taxing wealthy endowments down to zero, the majority of Americans would stand up and cheer.

It was all unnecessary. Colleges could have stayed out of overtly political issues, especially the ones outside their professional expertise.

Update: Here is an example of how far colleges have degenerated, from a Jewish magazine:

A man sentenced to life imprisonment for involvement in the murder of four Jews in a French synagogue bombing is teaching a “social justice” course at a Canadian university.

Dr Hassan Diab, a Lebanese-Canadian citizen, was found guilty by a French court for taking part in the 1980 bombing outside the Rue Copernic Reform synagogue in Paris, which killed four people and injured 46.

He is employed at Carleton University, in Ottawa, Canada, as a teacher in sociology and is delivering a class this autumn titled “Social Justice in Action”.

Horgan defends SciAm Politicization

I mentioned that the SciAm Editor is Fired, and former SciAm writer seems to be the only one defending her.

He maligns evolutionist Jerry Coyne, who argues back. See also Jesse Singal.

I post this so that you can see that it is a real dispute. The SciAm editor would surely say that scientists should be aware of the dangers of Trump fascism or transphobia or some other political issue. I wish the magazine would stick to science. Others can debate the pros and cons of Trump.

If SciAm were to address political issues, then it should at least provide some balanced coverage. But no, it forbids any articles expressing contrary views. Sorry, that is not a scientific view.

Update: Michael Shermer adds his experience::

I wrote 214 consecutive monthly columns for Sci Am, from 2001–19. Only two of these were rejected, both in 2018.

SciAm Editor is Fired

Jerry Coyne reports:
The facts are that Helmuth had a total social-media meltdown the night of the election (see her tweets here), for which she later apologized (see tweet here).  People called for her to be fired given the tenor of what she wrote, but I’ve never done that. We don’t know if she resigned or was fired, and it really makes no difference.
Her tweets revealed her to be a crazy leftist Trump-hater, but I would not have fired her for that. I do not believe in canceling people for emotional outbursts of silly opinions.

She should have been fired for turning Scientific American into a radical woke propaganda magazine that put ideology ahead of science. Trump just announced appointing RFKjr to HHS yesterday afternoon, and SciAm already has an article attacking him!

Update: More info at Unherd:

Four years ago, it made a presidential endorsement in support of Joe Biden for the first time in its 175-year history. ...

Helmuth’s tenure also saw the publication of articles that blurred the lines between scientific research and activism. A 2021 article, “From Civil Rights to Black Lives Matter”, addressed what makes various social justice movements successful. “Social movements have likely existed for as long as oppressive human societies have, but only in the past few centuries has their praxis […] developed into a craft, to be learned and honed,” the article read. Several articles argued in favour of abortions, with one headline claiming: “Third-Trimester Abortions Are Moral and Necessary Health Care.”

The outlet published numerous articles promoting transgender medical interventions. It also published articles advocating against age restrictions for these procedures. One such article claimed that “a decade of research shows such treatment reduces depression, suicidality and other devastating consequences of trans preteens and teens being forced to undergo puberty in the sex they were assigned at birth”, a proposition that has come under international scrutiny in recent years.

Academics are Depressed about Trump

Peter Woit is depressed about the election, and rants that now we are Living in a Post-truth World
On the American democracy front, the Trump phenomenon embodies post-truth in its purest form, with the full triumph now of a movement devoted to saying whatever will get them to power, with less than no interest in whether any of it is true.
He complains that super-smart physicists promote untenable string theory, or as one comment says:
Indeed, if Physics PhDs can look you in the eye and say that they really believe that wormholes form when you entangle spins simply because Maldacena and Susskind say so, why should you be so surprised that people get taken in by demagogues?
Okay, but Woit also complains that big money was allowed to influence the election, that Fox News was allowed to be different from the other networks, and that Trump won the less educated voters and lost the more educated voters!

This make no sense. The big money outspent Trump maybe 3-to-1, or 5-to-1, in the election.

If the super-high-IQ super-educated physicsts can be wrong about string theory and entangled electron wormholes, then why can't they be wrong about Trump?

The whole idea that the Democrats are on the side of Truth, and Trump is opposed, is absurd. These Trump-haters cannot give any examples.

Kamala Harris knows nothing about science. The closest she gets is dopey babbling like:

So, let me say this: This is an issue that Josi actually highlighted in terms of the importance of this. The Governor and I and we were all doing a tour of the library here and talking about the significance of the passage of time. Right? The significance of the passage of time.

So, when you think about it, there is great significance to the passage of time in terms of what we need to do to lay these wires, what we need to do to create these jobs. And there is such great significance to the passage of time when we think about a day in the life of our children and what that means to the future of our nation, depending on whether or not they have the resources they need to achieve their God-given talent.

She also said she believes in Astrology!

I don't want to pick on Woit, as he lives in a bubble where no one supports Trump. Most of American elite academia have Trump Derangement Syndrome. They have no grasp of what Trumpism is about, and can only babble platitudes about Truth.

I cannot even figure out what Woit means by "post-truth", as he only gives a few hints. He mentions Newt Gingrich, who was House Speaker for several years in the 1990s. He is mostly known for passing some reforms, after the other party controlled for decades. He mentions Fox News reporting on Clinton Whitewater, but that was an investigation ordered by Clinton's attorney general. Not much came of it. Mentions a Michio Kaku book on parallel universes. Yes, that is all a big fantasy.

Perhaps Woit is alluding to Trump's reputation for exaggeration. Yes, he sometimes exaggerates. He claimed to pull off the greatest comeback in American political history, if not world history. Dubious. Nevertheless, he is a much more authentical character than Kamala Harris. He is what he appears to be. Harria was unable or unwilling to say who she is, and what her agenda is. She convinced people that she is pro-abortion and hates Trump, and nothing else. Those voting for her had very little idea what she stood for.

Harris and Walz also told a great many lies.

I think Woit is from another country, and may have very little understanding of American politics. His criticisms are lazy and stupid. Trump was President for four years, and it was four years of peace and prosperity. Disagree with him if you want, but most of the opposition to him consists of calling him a fascist. His decisive win in the election is from a common and informed view that he was the much better candidate.

Attention for Hossenfelder's Science Channel

NPR reports:
The dark days of the COVID-19 pandemic helped transform Sabine Hossenfelder into an unlikely social media star. ...

Hossenfelder's science channel has also become a ready platform for her somewhat contrarian views on the state of physics. Among them is what she sees as the problem of beauty, the pursuit of simplicity. Specifically, how her colleagues who try to fathom the fundamental underpinnings of the universe are obsessed with it. ...

But as we seek answers in a complex universe, Hossenfelder cautions that the quest for simplicity could be a dead end. ...

Posting videos to the internet, it turns out, generates a more reliable revenue stream to fund her work in quantum gravity.

Her videos have a lot of good info, but quantum gravity is a waste of time.

A less favorable review from Professor Dave:

Sabine Hossenfelder is a very popular science communicator who focuses largely on topics in physics. Although much of her content is effective and without issue, there is an undercurrent of anti-establishment rhetoric that has grown immensely as of late, and it is an enormous problem. Sabine is a not a charlatan like most of my other targets, and this is not a hit piece, but rather commentary on this aspect of her work and how it came to be. If you are a fan of hers, consider this perspective.
Professor Dave is not a professor, and not a physicist. His main complaint is that she has harsh words for those doing Physics research, and he says there is lots of good reseach. But her main gripes are with those doing dead-end research in certain foundational and speculative areas.

She has a new video in response, where she doubles down on her point that the last 50 years have made no progress in foundational issues.

I would say quantum gravity is one of those dead-end areas where all or nearly all research is worthless.

Actually I might argue that foundational Physics has made negative progress, as many have jumped on absurd theories like many-worlds.

Because Professor Dave is not a physicist, I don't think he appeciates how much theoretical Physics has lost its way.

Both of these channels have a lot of worthwhile videos. My main beef with her is that she subscribes to superdeterminism, a concept contrary to the whole scientific enterprise.

Update: Professor Dave has doubled down with another attack video:

I criticized some unprofessional behavior regarding her choice of titles, thumbnails, and generalized deceptive anti-science rhetoric which has clearly been fueling science denial among the public in large numbers. ... All of those people wanted to talk about academia, so let's talk about academia a little bit in this video, while also addressing an unbelievably immature response video from Sabine where she doubled down on all of her bullshit rhetoric and made things much, much worse for herself.
He goes on to say Hossenfelder is a science denier.
This is how we get politicians voted into office 4:40 with fascist leanings. This is how the slide down the slippery slope towards theocracy 4:45 gains momentum. This is how we get people trying to force religion into public schools, and into federal laws. With Trump returning to office, he may follow through with his promise 4:56 to put RFK in charge of the department of health. RFK. An anti-vaxxer who has said that chemicals 5:03 in the environment can turn kids gay and trans and that HIV does not cause AIDS, may soon be 5:10 in charge of the FDA, NIH, USDA, and CDC. Are you listening to me? ...

As a global society we are sliding towards idiocracy, 5:37 and our survival as a species is at stake. Sabine feeds people narratives that are conducive to 5:43 those modes of thought, and in doing so she is pushing them further down the pseudoscience pipeline where they are more likely to be ensnared by actual demagogues and charlatans.

Meanwhile, Dr. Bee is back with My problem with the black hole information loss problem. She has legitimate complaints about unscientific papers about black hole information physics. Prof. Dave wants to blame her for Trump getting elected.
