Radiation paradoxes 14: What others have said about this problem

(Previous posts in this series: Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, Part 7, Part 8, Part 9, Part 10, Part 11, Part 12, Part 13)

The history of analyses of the question “Does a charge falling freely in a gravitational field radiate energy?” is quite fascinating with experts being all over the place, even to this date. The biggest disagreement is over whether the answer to the above question is yes or no. But even among those who agree on the answer, there are disagreements as to the reasons. For example, among those who say that it radiates, some argue that it leads to a loss in kinetic energy and that the Principle of Equivalence may not even hold in the case of a charge falling freely in a uniform gravitational field. Others disagree on what the source of the radiation is.

Among the Trumpists

I have to admit that hearing Trump supporters say the most clueless things seems to never get old. I am impressed by Jordan Klepper’s ability to find among them people who can be made to say the most absurd things.

Fellow Daily Show correspondent Michael Kosta seems to be developing his chops in this area as well as he asks them what they think of Trump’s Space Force.

What is Ricky Gervais’s problem?

Comedian Ricky Gervais seems to have gone off the rails in a big way. After his breakthrough series The Office and the enjoyable film The Invention Of Lying, he seems to have run out of ideas and resorted to what other comedians have done in that same situation and that is resort too cheap jokes targeting marginalized groups.

I wrote before about his Netflix stand up special that I stopped watching when he began with an extended riff where he repeatedly dead-named Caitlyn Jenner, presumably as a response to him being criticized for doing so when he hosted the Golden Globes. Rather than. take the occasion to redeem himself, he doubled down, and seemed smugly proud for doing so.

But that is not all. He has written, directed, and stars in a comedy-drama series on Netflix called After Life where he plays a reporter for a small town weekly community free newspaper. He is deeply grieving over the death of his wife from cancer, so much so that he was suicidal at one point and often acts like a jerk towards other people. The series was getting very good reviews and I decided to watch it, thinking that perhaps he had learned something from the criticisms of his Netflix show.

Djokovic and the French Open

After being kicked out of Australia for not meeting that country’s requirements for entry, tennis player Novak Djokovic now faces another hurdle. France has just passed a law saying that only vaccinated people will be allowed in public places. The French Open tournament is in May.

The world number one, however, faces more immediate hurdles in his bid to overtake Swiss Roger Federer and Spaniard Rafa Nadal, with whom he is tied on 20 major titles, as he could be barred from the French Open as things stand.

The French Sports Ministry said on Monday there would be no exemption from a new vaccine pass law approved on Sunday, which requires people to have vaccination certificates to enter public places such as restaurants, cafes and cinemas.

“This will apply to everyone who is a spectator or a professional sportsperson. And this until further notice,” the ministry said.

“As far as Roland Garros is concerned, it’s in May. The situation may change between now and then and we hope it’ll be more favourable. So we’ll see but clearly there’s no exemption.”

More and more countries are implementing restrictions on people entering the country and if he continues to refuse to get vaccinated, his participation at Wimbledon, the US Open, and other tournaments could be in doubt.

Given the Australian fiasco, each country will likely be very careful that he meets all their requirements and that there is not even the slightest suggestion that he is being given special treatment or exemptions.

How the January 6th riot split one family

Vice had an article about a family that was split apart when the 18-year old son reported their father to the authorities that he had been part of the mob that invaded the Capitol building on January 6th, 2021. He will be the first person to stand trial next month for his role in the events.

On January 5 last year, Guy Reffitt, a member of the Texas Three Percenters militia, packed his AR-15 rifle and a Smith & Wesson pistol into his wife’s car and set off on the 1,300-mile journey from Wylie, Texas, to Washington, D.C.

The next day, armed with the pistol, he attended the “Stop the Steal” rally in front of the White House, then marched with the crowd over to the U.S. Capitol Building, where he allegedly charged at police officers with such force that they had to fire projectiles and use pepper spray to hold him back.

Reffitt, wearing body armor partially covered by a blue jacket and a black motorcycle helmet, was captured on video on a staircase on the West Front of the Capitol. He can be seen holding his hand up as a police officer sprays him in the face. Moments later cameras capture Reffitt, exhausted from battle, flushing out his eyes with a bottle of water.

When he returned to Texas, according to prosecutors, he delivered an ominous threat to his son Jackson, 18, and daughter Peyton, 16, about what would happen if they told anyone what he’d done: “If you turn me in, you’re a traitor, and you know what happens to traitors… Traitors get shot.”

What he didn’t know was that his son had already turned him in.
…

Jackson had actually tipped off the FBI in December, after becoming concerned about his father’s increasingly radicalized rhetoric, including claims he was “about to do something big.”
…

Jackson discovered his father was at the Capitol when Reffitt began posting pictures from the insurrection to the family chat group. With the riot still unfolding live on television, Jackson got a call from the FBI, who asked if his father was at the Capitol. Jackson confirmed that he was.

Radiation paradoxes 13: The mysterious mass of the electron

(Previous posts in this series: Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, Part 7, Part 8, Part 9, Part 10, Part 11, Part 12)

We seem to have arrived at a resolution to the paradox that this series started with that maintains our traditional expectations. Recall that it seemed like two postulates that were thought to be incontrovertible were incompatible when applied to a situation in which an electric charge and a neutral particle were dropped from the same height. It seemed like one or both had to be wrong. Those two postulates were:

Postulate #1: If we eliminate all other forces such as friction, all objects that are dropped from the same height in a gravitational field will fall at the same rate and hit the ground at the same time.

Postulate #2: An accelerating charge will radiate energy.

In the previous post, we arrived at a resolution in which the falling charge will radiate, in agreement with Postulate #2, but that this radiated energy does not result in a loss in the kinetic energy of the charge and thus it will fall at the same rate as the neutral particle, in agreement with Postulate #1.

The way this resolution was arrived at may not satisfy everyone. It involved invoking an aspect of the mass of a charged particle that we may not be familiar with. We looked at some aspects of the subtlety of mass back in Part 5. But there’s more, and this was the introduction of a mysterious source Q that provided the energy radiated by an electron that was accelerating under the influence of a uniform gravitational force. Recall that the rate of energy radiated by the charge was given by the familiar Larmor expression ℛ = 2e2g2/3c3 for a charge e having an acceleration g. Q = 2e2ao/3c2 where ao is the zeroth component of the covariant four-acceleration of the charge given by aμ = dvμ/d𝜏, such that ao = γv.a.

This is a little over the top, no?

Novak Djokovic has been expelled from Australia after an Australian federal court panel unanimously upheld the deportation order issued on him by the Australian immigration minister, Alexander Hawke, thus dashing his hopes of playing in the Australian Open that starts today.

I can understand his family and fans and his Serbian compatriots being upset. But the reaction has been way over the top, with the Serbian government also piling on.

[Serbian president, Aleksandar Vučić] said he was sure Djokovic “would have been treated differently if he hadn’t come from Serbia … If he was from another country, the approach would be completely different. Of course people here are frustrated, 90% are on Novak’s side.”

The player’s father, Srđan, said the episode amounted to “an attempted assassination with 50 bullets to the chest”, while the sports minister, Vanja Udovičić, described it as “nonsense and shame, absurdity and hypocrisy”.

The full sordid web of Jeffrey Epstein is still to be revealed

Branko Marcetic writes that while the trial of Ghislaine Maxwell did not blow the lid off the whole sordid Epstein saga due to the prosecutors being cautious in their efforts to secure a conviction, the process did produce quite a lot of information that did not get much media attention, that showed the web of high profile people who were part of his circle and traveled around with him. He concludes:

The Jeffrey Epstein saga is the story of the world’s most prolific child sex trafficker who operated more or less unhidden for decades, but was able to consistently escape media scrutiny, legal punishment, and, finally, justice by dying before he went to trial. In a normal world, this tale of sprawling criminality and public corruption would be the subject of an intense, wide-ranging government investigation that would expose the conspiracy’s full scope and the identities of those involved.

Instead, information about the case continues to come in dribs and drabs, thanks only to the work of a few dogged reporters and the occasional fortuitous legal disclosure, limited in this most recent trial by the judge’s order to avoid “needless” naming of names, and prosecutors’ decision to leave tens of thousands of photos seized from Epstein’s home by the FBI unreleased. The public may end up having to wait for the civil suit against Prince Andrew or for Maxwell herself to strike some kind of deal to learn more.

Just as with the John F. Kennedy assassination, obscuring the full truth of the crime has only fed the growth of disreputable nonsense like QAnon, which serves to launder and distract from the intimate involvement of elites like Trump in Epstein’s crimes, turning them into yet another culture war sideshow. This is the double tragedy of Epstein’s death: it’s denied many of his survivors full justice, and turned the terrible truth of his crimes into a shield for his fellow perpetrators.

Marcetic thinks that the Prince Andrew case, if it ever goes to trial, may reveal more details.
