Most accurate in the history of science

New paper:
Quantum Electrodynamics (QED) is considered the most accurate theory in the history of science. However, this precision is limited to a single experimental value: the anomalous magnetic moment of the electron (g-factor). The calculation of the electron g-factor was carried out in 1950 by Karplus and Kroll. Seven years later, Petermann detected and corrected a serious error in the calculation of a Feynman diagram; however, neither the original calculation nor the subsequent correction was ever published.Therefore, the entire prestige of QED depends on the calculation of a single Feynman diagram (IIc) that has never been published and cannot be independently verified.
If this is really the most accurate and impressive prediction in the history of science, you are probably thinking that the theorists and experimentalists worked independently. Nope.

The theorists, who did it wrong, knew about the experimental value they were supposed to match. And they matched it, but the experimental value was wrong. The theoretical value happened to be also wrong in the same way. Then the experiment got redone to give a more accurate value, and an embarrassing disagreement with theory. So the theoretical value was redone, with this knowledge, and the new theoretical value matched the new experiment. The details were never published.

I have heard of experiments being cooked to match the theory. The history of this seems to be the opposite.

Bohm and his groundbreaking ideas

I just got an email (ie, spam) saying:
If you are considering a gift to a family member or a friend this THANKSGIVING, why not consider the gift of David Bohm and his groundbreaking ideas. Bohm’s ideas are an enduring gift to mankind, enabling a paradigm shift for the transformation of self and society.

The recent and current political events taking place in the United States and the Covid-19 pandemic has given us all time to reflect on the vulnerability of our Political, Economic, Spiritual and Social structures. David Bohm’s enduring answers to mankind’s big questions opens a door to coherence, wholeness and interconnectedness. We just need to pay more attention!

So once again we want to THANK YOU all so much for your support and encourage you to share INFINITE POTENTIAL with family, friends and those who you feel would appreciate the gift of Bohm.

Wow, is that a reference to Pres. Trump challenging the vote count in several states? That and some flu-like virus are supposed to make me purchase a movie about David Bohm and give it to a friend for Thanksgiving?!

Let us be clear about his groundbreaking ideas. He believed in (1) Communism; (2) determinism; and (3) spooky action-at-distance. Each of these is fundamentally wrong, and we should be happy that we live in a world where they are wrong. The world would be a depressing place if any of these were correct.

But do they "opens [sic] a door to coherence, wholeness and interconnectedness"? I don't know what there nuts are even thinking, and I watched the movie. I post this in case anyone else wants to try to figure it out.

For more reading, try his biography, or philosophical essays. I previously posted a link to the movie, but it has been taken down.

The dark state is erased

Mikhail Gromov, one of the greatest living geometers, once wrote:
This common and unfortunate fact of the lack of an adequate presentation of basic ideas and motivations of almost any mathematical theory is, probably, due to the binary nature of mathematical perception: either you have no inkling of an idea or, once you have understood it, this very idea appears so embarrassingly obvious that you feel reluctant to say it aloud; moreover, once your mind switches from the state of darkness to the light, all memory of the dark state is erased and it becomes impossible to conceive the existence of another mind for which the idea appears nonobvious.
This is actually a common view among mathematicians, but only mathematicians. It is one of the things that makes Mathematics difficult for outsiders.

SciAm says: Always trust the experts

SciAm reports:
To Understand How Science Denial Works, Look to History

The same tactics used to cast doubt on the dangers of smoking and climate change are now being used to downplay COVID

By Naomi Oreskes | Scientific American December 2020 Issue ...

But while the events of 2020 may feel unprecedented, the social pattern of rejecting scientific evidence did not suddenly appear this year. There was never any good scientific reason for rejecting the expert advice on COVID, just as there has never been any good scientific reason for doubting that humans evolved, that vaccines save lives, and that greenhouse gases are driving disruptive climate change.

SciAm blogger John Horgan posts a somewhat contrary opinion.

There certainly was good scientific reason for doubting expert advice on COVID.

First of all, much of the advice has been contradictory, such as whether to wear face masks.

Second, none of their predictions have come true.

Third, there was never much scientific support for their policies, such as closing the schools.

As I write this, there is a new set of lockdown orders. I believe that they are doing more harm than good. As far as I can see, there is not even any good published analysis to support these policies.

The experiment that made Einstein famous

Einstein became world-famous on 7 November 1919, following press publication of a meeting held in London on 6 November 1919 where the results were announced of two British expeditions led by Eddington, Dyson and Davidson to measure how much background starlight is bent as it passes the Sun. Three data sets were obtained: two showed the measured deflection matched the theoretical prediction of Einstein's 1915 Theory of General Relativity, and became the official result; the third was discarded as defective. At the time, the experimental result was accepted by the expert astronomical community.
This made Einstein world-famous, as the NY Times headline was:
LIGHTS ALL ASKEW IN THE HEAVENS; Men of Science More or Less Agog Over Results of Eclipse Observations. EINSTEIN THEORY TRIUMPHS Stars Not Where They Seemed or Were Calculated to be, but Nobody Need Worry. A BOOK FOR 12 WISE MEN No More in All the World Could Comprehend It, Said Einstein When His Daring Publishers Accepted It.
There has long been some controversy about this, as they discarded the result that would have agree with Newtonian gravity. It is often cited as an example of scientists seeing what they want to see.

This paper argues that the orginal eclipse experiment was legitimate.

Many religions do reject free will

Evolutionist Jerry Coyne posts commonly against theism and free will, and complains
about a video on the physics of free will:
O’Dowd seems hung up on predictability as an important part of free will. But all of us, including hard determinists like me, realize that we will never be able to predict human behavior with 100% certainty. Not only do too many factors impact our brains and behavior, but, as O’Dowd points out, the uncertainty principle bars us from even knowing certain fundamental properties of quantum-behaving particles (although those may have a negligible effect on behavior). But whether or not we can predict behavior seems to me irrelevant about whether or not we have free will.
Coyne denies free will because he believes in determinism, but he oddly says predictability is irrelevant.

I was more surprised by this statement:

And, of course, libertarian free will is an underpinning of all Abrahamic religions.
No, it is not.

See the Wikipedia article on Free will in theology. Islam is always talking about the will of Allah determining everything. Humans have no free will. Free will plays no role in Judaism.

Catholics and Mormon believe in free will. Protestant Christians have varying views, but many of them partially or wholly reject free will.

The video says free will is “the most directly verifiably real thing you will ever observe”. [at 12:30] I agree with this. You can just close your eyes and make a choice. You can sense your free will more directly and you can sense the Sun rising in the East.

Coyne acts as if he has to disprove all the religions, and then convince everyone that they do not have free will, in order to teach them some superior atheist world view. The truth is more nearly the opposite. Religion is encouraging a denial of free will, and then bad morals.

Covariant with respect to Lorentz transformations

Philosopher Harvey R. Brown has a nice new paper on Noether and symmetry. He comments:
Einstein's 1905 derivation of the Lorentz transformations rested on two fundamental symmetry principles: the relativity principle (dynamical equivalence of inertial frames) and the isotropy of space, alongside the postulate governing the constancy of the speed of light with respect to the "resting" frame.74 The justification of all these principles did not rest, for Einstein, on any a priori notions about the structure of space and time, but was based on "plenty of experiential knowledge" related to mechanics and electrodynamics.75 Later, he would stress that the theory of special relativity could be summarised in one principle: "all natural laws must be so conditioned that they are covariant with respect to Lorentz transformations".76 This allowed Einstein to say that the theory transcended Maxwell's equations, and what he saw as the awkward emphasis on the role of light in his 1905 formulation.77 Special relativity is essentially a constraint in the sense that a symmetry is being imposed on the fundamental equations of all the non-gravitational interactions.
These EInstein opinions are from 1940 and later, long after that 1905 paper.

The principle that all natural laws must be so conditioned that they are covariant with respect to Lorentz transformations was written by Poincare in 1905 and Minkowski in 1907, but not endorsed by Einstein until about 1915. If that is really the essence of special relativity, then all the credit should go to Poincare and Minkowski, as Einstein contributed nothing to this line of thought.

This is the biggest reason I believe Einstein should not be credited with the discovery of special relativity. It is not just that others had the formula earlier. It is that the essence of the theory is Lorentz covariance, and Einstein did not even understand the concept until many years after others had published it and gained widespread acceptance.

The Brown paper does have a good discussion of the history of Noether's theorem. Nowadays, conservation of momentum and energy are considered synonomous with symmetries of spacetime. This was one of the most important insights of XX century Physics.

Scientists aghast as Trump not repudiated

Nature, the leading British science publication, endorsed Joe Biden and now reports:
Scientists aghast as hopes for landslide Biden election victory vanish With so many votes cast for Trump in US election, some researchers conclude that they must work harder to communicate the importance of facts, science and truth.

As the possibility of a land-slide victory for US presidential candidate Joe Biden vanished in the wee hours of 4 November, some scientists saw the deadlocked election as a sign of their own failure to communicate the importance of science, evidence and truth to the general population.

“This election is not going to be a decisive national categorical repudiation of Trump, regardless of who wins the presidency,” says James Lindley Wilson, a political scientist who studies elections and democracy at the University of Chicago. ...

But as in 2016, Trump outperformed polls suggesting that his opponent was positioned for a potential landslide victory. ...

“Evidently a lot of Floridians are in denial about climate change,” says Oreskes. “How do we fix that? I don’t know, but obviously what we’ve been doing has not worked.”

Michael Lubell, a physicist at the City College of New York who tracks science policy, worries about what the results of the election say about the value that many Americans put on truth.

The article was written before Biden claimed victory.

I am a big believer in science, evidence, and truth, but never had any understanding of any scientific issue, ever before he went senile. There was no scientific reason to prefer Biden over Trump. The election was decided over other issues.

I am aghast at how the scientific establishment has been politicized, and signed onto a left-wing agenda.

Biden's first act, as apparent President-elect, was science-related:
A professor with the Yale School of Medicine will serve as a co-chair of President-elect Joe Biden’s task force on the coronavirus, according to a report from CNN. ...

According to her biography on the Yale School of Medicine website, Nunez-Smith’s “research focuses on promoting health and health care equity for structurally marginalized populations with an emphasis on supporting health care workforce diversity and development, developing patient reported measurements of health care quality, and identifying regional strategies to reduce the global burden of non-communicable diseases.”

Pres. Trump appointed experts for their competence in the field. This is obviously being appointed for her skin color, sex, and attention to "structurally marginalized populations", whatever they are. Her research does not even involve communicable diseases, and may not know any more about COVID-19 than I do.

If these scientists and science organizations were really so focused on "science, evidence and truth", then they would be criticizing this appointment. They will not.

Update: Scott Aaronson celebrates the Biden-Harris win, and says "I would love for Twitter to deactivate Trump’s account". No mention of any possibility of new policies that would make America a better place.

The comments point out that the Trump administration lacked the foreign policy disasters of the previous Bush and Obama administrations. One comment points out that 70 million citizens voted for Trump, and they certainly did not believe that Trump was sent by God to fight Satanic pedophiles, as Aaronson had claimed. It is clear that his support for Biden was just Trump hatred.

Another comment says:

I don’t see how anyone who has listened to Trump’s diatribes over the past four years and still chose to vote for him could be anything other than a right wing authoritarian.
So we have 70 million right-wing authoritarians? No, I don't know any.

If Trump were really an authoritarian, he would have used the COVID-19 crisis to seize new powers, and to order compliance with his policies. He did not. Instead, Joe Biden has promised to order dictatorial mandates such as wearing masks.

SciAm: 7 Presidential differences

SciAm lists 7 ways the election will affect science issues. I paraphrase:
Pandenmic. Biden's plan is essentially the same as what Trump has done, with the main difference that Biden says that he will order a national mask-wearing mandate. However, Biden's web site omits mentioning the mask mandate.

Clean air. The Trump administration has brought the cleanest air ever, but Biden promises to reduce CO2 by shutting down the fossil fuel industry.

Health care. Trump has reduced medical and drug costs, and expanded health care options. Biden promises a "public option" so that govt plans would replace private health insurance.

Peace. Under Trump the world has been the most peaceful ever. Biden says that he will end the sanctions against Iran.

Immigration. Trump has reduced legal and illegal immigration. Biden would move toward open borders, and policies that systematically replace American jobs with foreigners.

Space. Trump has us going back to the Moon. Biden may kill that.

Federal land. Trump has used federal land to gain energy independence. Biden will shut that down.

It is notable what SciAm does not say. There is no claim that Trump failed to fund some important area of science, that he censored any good science, or that he failed to follow expert advice on COVID-19 or anything else. It does criticize him with comments like this:
His own chief of staff recently admitted that “we are not going to control the pandemic.”
That's right, we are not going to control it. The pandemic is going to run its course. Some policies have probably reduced its spread, and some treatments have improved, and we may soon have vaccines. But none of these things will eliminate the virus.
If Trump remains in power, his administration will likely continue to restrict people born elsewhere from entering the country, driving many stars of artificial intelligence, quantum computing and other fields to take their valuable talents elsewhere.
There is no complaint about the billions of dollars that Trump is pouring into AI and QC. The complaint is that too much of that money is going to Americans, and Biden will give most of it to foreigners.

Of all the science issues to bring up, why AI and QC? AI threatens to enslave us all to robot overlords. QC threatens to destroy our secure communications. These are just the things that we should not be putting under the control of foreigners.

Coyne responds to free will video

Jerry Coyne responds to an amusing video attacking his opinions on free will:
Hunter goes off on all kinds of antievolution tangents in this video, failing to stick to the promised critique of determinism. That’s probably because his critique can be summed up very simply: “There’s no evidence for determinism — it’s just a weird and bizarre pronouncement of scientists like Cohen, and constitutes “scientism.” ...

I can rebut both of these claims very briefly.

There’s no evidence for determinism. This claim is absurd. The response is that everything on Earth, and, as far as we can tell, in the solar system, in the Milky Way galaxy, and in Universe, has uniformly obeyed the laws of physics since the Big Bang. That’s not a speculation, but an empirical conclusion ...

We can have no confidence that we can find truth if determinism be true. The rebuttal of this can be conveyed in two words: natural selection. Animals, including us, could hardly survive if we had sensory systems that didn’t give us a fairly accurate representation of reality: where the dangers lie, where the food is, what happens if we jump off a cliff.

The discussion has religious overtones, as "Cohen" seems to be a reference to Coyne being a cultural Jewish atheist.

To the extent that free will is a religious or philosophical issue, they are all entitled to their opinions. I just want to address the science.

Saying that the Milky Way galaxy obeys the laws of physics, and deducing determinism and a lack of free will is illogical.

How leftist philosophers censor scholarly work

Massimo Pigliucci is a biologist-turned-philosophy-professor who is very opinionated about the philosophy of science. He used to have a large web presence, and I have commented on his blog many times, but I quit because he would arbitrarily delete my comments if he did not agree with them.

He is a good example of what is wrong with today's philosophy of science. I have explained some of his erroneous thinking several times on this blog.

Now Pigliucci has lauched a campaign to censor another scholar for some race-related work.

Nathan Cofnas wrote Research on group differences in intelligence: A defense of free inquiry, and it was published in a respected journal.

They argue as follows.

First, Pigliucci and his coauthors argue that it is an error to even talk about human races because no races were ever completely pure, isolated, and phylogenetically distinct for an evolutionarily prolonged time. This is a strawman attack, because neither Cofnas nor anyone else ever said that they were.

Second, they say that Cofnas is the one making the strawman attack, because "Allegedly, Cofnas felt compelled ... He seems to think ... perspective is significantly out of tune". In other words, they are doing some mindreading, and criticizing what is in Cofnas's head instead of what is in his paper.

Third, they attack the editors for publishing a paper that undermines leftist policy goals.

They demanded, and ultimately pressured the journal to accept, publication of their criticisms without any rebuttal from Cofnas. The rationale was that since the whole point of the criticism is to censor Cofnas for discussing a taboo subject, it would be inappropriate to let him respond.

This while thing is just another example of how leftist creeps have corrupted academia. Pigliucci  knows enough biology to know that races are scientifically meaningful. After all, you can send your spit to a DNA lab, and it will tell you what race you are. Many scholars have apparently decided that they can insulate themselves from accusations of racism if they pretend to subscribe to a fiction that races do not exist.

It will not work. The academic race scholars of today say that race is a social construct, but still say that all Whites are inherently and immutably racist. That argument is being used to say White people should pay reparations to Black people, and we even have a Presidential candidate whose web site endorses appointing a commission to make such recommendations.

The biggest selling academic racism book of the last several years has been White Fragility. It argues that the worst racists of all are Whites like Pigliucci who deny the reality of race. I am not endorsing that opinion, but pointing that he cannot avoid racism accusations by denying the reality of race.

Professors are living in a Leftist bubble

Today's American professors are living in a bubble, where everyone they know is a leftist Trump-hater.

Professor Jerry Coyne writes:

I don’t know what prompted this, but I don’t think most members of the American Left want to abolish the Constitution. And because one branch of the Left is behaving in an authoritarian and illiberal manner, Lindsay is going to vote for TRUMP??????? Has he considered what four more years of a Trump administration would be like compared to a Biden administration? Does he think it would be better, or is he simply sending some kind of petulant signal to the regular Left? And what does it mean to say that he’s “unhappily voting Republican, including Trump.” Unhappily? Why is he voting at all?
It appears that Coyne does not know any Trump supporters, and fails to understand why another academic at another university might vote for Trump.

63 million Americans voted for Trump in 2016. Yes, many smart people compare the Trump administration to that of Obama or to what Biden promises, and prefer Trump.

In last night's debate, Biden did promise "science over fiction". But there is no example of him or his campaign being more scientific about anything. He also tried to claim that the corruption charges against him and his family were some sort of Russian conspiracy!

Dr. Bee on Bohmian pilot wave theory

I posted a criticism of a new movie on David Bohm and pilot wave theory. Unfortunately, it has now been taken down, as the producers are using it for fundraising.

Now Dr. Bee has posted a more detailed criticism of the theory.

One of the big disadvantages of Bohmian mechanics, that Einstein in particular disliked, is that it is even more non-local than quantum mechanics already is. That’s because the guiding field depends on all the particles you want to measure. This means, if you have a system of entangled particles, then the guiding equation says the velocity of one particle depends on the velocity of the other particles, regardless of how far away they are from each other. ...

[Reader:] The argument against Bohmian mechanics is that it is non-local, and QFT requires locality. But didn't Bell prove that the universe is non-local (for most physicists at least; I realize you have an alternative explanation for his results)?

[Sabine Hossenfelder:] First, you cannot use a mathematical theorem to prove how the universe is. What Bell proved is that theories of a certain type obey an inequality. Experiment shows that this inequality is violated. It follows that one of the assumptions of Bell's theorem must be violated.

A violation of one of these assumptions is qua definition what people in quantum foundations call "non-locality". It is an extremely misleading use of the word and has nothing to do with that particle physicists call "non-locality" which refers to non-local interactions.

These two different types of non-locality have caused so much confusion I really think we should stop referring to quantum mechanics as "non-local". Some have suggested to instead use the term "non-separable" which makes much more sense indeed.

In any case, Bohmian mechanics violates Bell's inequality and is thus non-local in Bell's sense. This is fine and not the problem I was talking about. The problem is that the ontology of Bohmian mechanics is non-local in the QFT sense (as I explained in the video). This is not necessarily a problem, but certainly one of the reasons why it's been hard to make a QFT out of it. The other problem is Lorenz-invariance (which I refer to as the "speed of light limit).

This is an important point.

Bell nonlocality is an abuse of terminology that only confuses people. Bohm's theory is truly nonlocal in a way that no scientific theory is. It is a fringe theory that no one has found useful for anything.

Sometimes someone claims that Bohm's theory is more intuitive, but that is nonsense. The nonlocality makes it more counter-intuitive than any other textbook theory.

When she said the "historical context is relevant", I thought that she was going to tell us that Bohm was a Commie. It is funny how he has a cult following. There is some weird ideology driving support for his theory, but even after watching the movie, I cannot figure out what it is.

Another comment:

Bohm's theory is convinient for quantum cosmology, since it avoids the problem of the system and the observer which are necessary in the Copenhagen interpretation so that the Copenhagen interpretation cannot be applied to the whole universe.
The theory is nonlocal, so events in one galaxy can depend on subtleties in another galaxy. And that is supposed to be convenient for cosmology? I doubt that it has ever been of any use to cosmology.

Update: Here is a new PBS Space Time video addressing some of these issues.

First prize to a mathematical physicist

Giving the Nobel prize to Roger Penrose is striking because it is so rare that the prize has gone to the mathematical physicist. He might be the only one, altho an argument could be made that Wigner and 'tHooft were also examples.

You are probably thinking that there have been lots for prizes for theoretical physicists, such as Einstein, Dirac, Pauli, Feynman, etc. And they all use heavy mathematics.

But not really. There is a big difference between theoretical physicists and mathematical physicists.

Wikipedia explains:

The term "mathematical physics" is sometimes used to denote research aimed at studying and solving problems in physics or thought experiments within a mathematically rigorous framework. In this sense, mathematical physics covers a very broad academic realm distinguished only by the blending of some mathematical aspect and physics theoretical aspect. Although related to theoretical physics,[3] mathematical physics in this sense emphasizes the mathematical rigour of the similar type as found in mathematics.

On the other hand, theoretical physics emphasizes the links to observations and experimental physics, which often requires theoretical physicists (and mathematical physicists in the more general sense) to use heuristic, intuitive, and approximate arguments.[4] Such arguments are not considered rigorous by mathematicians, but that is changing over time.

Penrose's work is squarely within mathematical physics.

Nobel prizes were not given for this before. For example, a prize was not given for CPT symmetry, even tho it is considered a fundamental theorem.

Articles about this year's prize raise the related question -- why give a relativity prize to Penrose when Einstein did not get prize for relativity?

For example:

Even when an award goes to the right person, it may be for the wrong -- or at least arguable -- reasons. Such is the case with Albert Einstein, whose 1921 physics Nobel was bestowed not for the theory of relativity but for his work on the photoelectric effect.
That article describes dubious prizes given for inventing poison gas and the lobotomy.

But Einstein was still not a mathematical physicist. The essence of Penrose's prize-winning contribution was a mathematical proof, but no one would say that about Einstein's contributions.

In the case of special relativity, Einstein's contribution is not considered mathematical because all those math formulas had been published already by others. Those who credit him credit him for a metaphysical view, as the math was not new, and the physical consequences were not either. The Nobel committee does not give prizes for metaphysical views.

Perhaps Einstein could have gotten one for general relativity, and it might have been shared with Grossmann and Hilbert. Maybe the committee had trouble assessing what Einstein really did, since he hid his sources so well.

Another comment from a biology professor:

Darwin’s theory is, like Einstein’s, amazing because of its sui generis character — because it didn’t involve much standing on the shoulders of giants who came before. And that is why we celebrate Darwin (and, to a lesser extent, Wallace), and don’t hail Arabic scholars as unrecognized harbingers of evolutionary theory.
I don't get this at all. Einstein's work depended very heavily on earlier work. So did Darwin's, and Darwin acknowledges it.

Another journal endorses Joe Biden

The British journal Nature, maybe the top science journal in the world, editorializes:
On 9 November 2016, the world awoke to an unexpected result: Donald Trump had been elected president of the United States.

This journal did not hide its disappointment. ...

Trump claims to put ‘America First’.

There is the heart of the gripe -- a bunch of non-Americans complaining that the American President puts America first.

Getting to more specific gripes:

In the pandemic’s earliest days, Trump chose not to craft a comprehensive national strategy to increase testing and contact tracing, and to bolster public-health facilities. Instead, he flouted and publicly derided the science-based health guidelines set by the US Centers for Disease Control and Prevention (CDC) for the use of face masks and social distancing.
No, the CDC told us repeatedly that face masks were useless, and not to wear them.
With the nation’s death toll now exceeding 215,000, the coronavirus has killed more people in the United States than anywhere else.
The coronavirus is listed as the cause of death in only 6% of these. The rest had other comorbidities.
No president in recent history has tried to politicize government agencies and purge them of scientific expertise on the scale undertaken by this one.
Not even one example of a scientist fired.
Trump has also promoted nationalism, isolationism and xenophobia — including tacitly supporting white-supremacist groups. ...

The United States’ reputation as an open and welcoming country to the world’s students and researchers has suffered.

Now we are getting to the real gripes.
Joe Biden, by contrast, has a history in the Senate as a politician who has reached across to his political opponents and worked with them to achieve bipartisan support for legislation
His best-known examples are the Crime Bill, which he now disavows, and the Iraq War, which no one wants to talk about.
He has pledged that decisions on the pandemic response will be made by public-health professionals and not by politicians; and he is rightly committing to restoring the ability of these professionals to communicate directly with the public.
Trump regularly put Fauci and other "public-health professionals" on TV. But yes, the decisions were made by elected officials.

It is sad how these scientific journals have been politicized. I am not sure I will ever trust them again.

It would be one thing if the President said things which were scientifically false, or fired scientists and replaced them with astrologers, or somehow sabotaged scientific works. But nothing like that is even alleged. He has funded the most worthy scientific projects, and promoted science. In his handling of COVID-19, he was open, transparent, and following the advice of the best experts. No one can explain how he could have done any better.

This is all political, and it has very little to do with science. Trump is hated for other reasons.

Update: Other Nature articles are political, such this recent obituary of Ruth Bader Ginsburg. It is not clear why a science journal would publish an obituary of a judge in another country. The only specific opinion of hers mentioned was her very-partisan dissent in favor of recounts that were thought to favor Gore in the 2000 election.
