He died a week ago at 97, Dr. Richard L. Garwin, a polymath. He's the guy who designed the hydrogen bomb and then (among so many other accomplishments) went on a life-long mission to reduce the risks it posed.

Linked here are 2 fascinating articles concerning Garwin (in particular the 1st, by a man who interviewed him many times over the years) and the secret history of ultra powerful nuclear weaponry by the USA and the Soviet Union.

The first of these articles is front page currently at The New York Times and the second is linked in that article.

The New York Times article can be accessed by all in this paywall penetrating link that is to terminate in 14 days, i.e. on June 2, 2025:


The 2nd article is as fascinating and shocking (and well written):


Note: The first article makes mention of a proposed bomb that would be 600,000 times the intensity of the atomic bomb dropped on Hiroshima in 1945. That would be 9 trillion tons of TNT: "One proposed version had the force of more than 600,000 Hiroshimas." The Hiroshima bomb was 15,000 tons TNT intensity.

The 2nd article has a lot of history and it's very well presented. One topic is the 100 megaton weapon that was developed, built and tested by the Soviet Union that was called Tsar Bomba or Emperor Bomb. At the last minute it was decided to replace a lot of the fissionable material with lead in order to reduce the yield to 50 megatons. The lead scientist calculated that some 660,000 premature deaths from radiation poisoning would be thus prevented. So, the test yielded 50 megatons.

The 600,000 x Hiroshima bomb was one of the brain-childs of Dr. Richard Garwin, a main subject of the New York Times article, which goes on:

That bomb wasn’t the only feat driven by Dr. Garwin’s prodigious intellect. He made basic discoveries about the structure of the universe, laid the groundwork for wonders of health care and computers, and won many awards. He pushed back frontiers in astronomy, physics, superconductors, orbital reconnaissance and a multitude of other topics he investigated, often at the U.S. government’s behest.

But what drove him, what made him eager to advise presidents, was not his gift for coming up with marvels of discovery and innovation but, courtesy of Fermi, a personal crusade to save the world from his own creation.


“The most influential scientist you’ve never heard of” is how his biographer cast him. The physicist told newcomers to the federal apparatus that they could get something done or get credit, but not both. He was, in some respects, the antithesis of Kissinger, who carefully tended his public image.

The polymath lectured and wrote papers on space weapons, land mines, terrorism, pandemics, submarines, science advising, food aid programs, automatic teller machines, Iran’s nuclear ambitions, the nation’s electrical grid, the disposal of radioactive waste, catastrophic risks and nuclear disarmament. The last entry in his comprehensive archive is dated early this year.

Tellers Sundial was basically the Doomsday weapon from Dr Strangelove. It was such a large bomb that if detonated anywhere on Earth (including the US) it would destroy all civilization so don’t you dare attack us.

Luckily cooler heads prevailed and it never left the planning stages.

Teller was also the origin for the Dr. Strangelove character. The man was totally nuts.

Plowshare, especially with the relatively dirty US weapons available, was crazy too.
 
There is no theoretical limit on the size of an H bomb. One can make the “neutron wick” as long as desired, a sort of nuclear det cord.
While true, nuclear/h-bomb detonations don't scale linearly with size, so you literally get more bang for your buck by dispersing small shit everywhere.

I believe it's the 2nd article linked in the OP that explains this rather well. It seems to be the reason 50, 100 (or larger) megaton bombs weren't created by the USA in the 1960's. The article explains this in considerable detail.

Navigational accuracy makes up for a lot of power. I.e. hitting the target.
 
From the NYTimes obit:

Dr. Garwin supported reductions of nuclear arsenals, including the 1979 Strategic Arms Limitation Treaty (SALT II), negotiated by President Carter and Leonid Brezhnev, the Soviet premier. But Dr. Garwin insisted that mutually assured destruction was the key to keeping the peace.

In 2021, he joined 700 scientists and engineers, including 21 Nobel laureates, who signed an appeal asking President Joseph R. Biden Jr. to pledge that the United States would never be the first to use nuclear weapons in a conflict. Their letter also called for an end to the American practice of giving the president sole authority to order the use of nuclear weapons; a curb on that authority, they said, would be “an important safeguard against a possible future president who is unstable or who orders a reckless attack.”

The ideas were politically delicate, and Mr. Biden made no such pledge.
 
Strange thing that a lot of all those people who handled nuclear material, they all died of old age , between 90 and 100 years old.
Fermi on the other hand died at a very young age, 53.

Madame Curie IIRC did die early due to her exposure to radioactive materials. Fermi, quite possibly.

He was 53.[2] Fermi suspected working near the nuclear pile involved great risk but he pressed on because he felt the benefits outweighed the risks to his personal safety. Two of his graduate student assistants working near the pile also died of cancer.[135]

Richard P. Feynman also died relatively young : 69 year old.
 
I recommend the book "Surely You're Joking, Mr. Feynman".
Thanks, well, my local library has it in audiobook, which I've IIRC never done before, but I put a hold on it. I suppose that means I listen to it using a device and my ears. But not my eyes. Hmm.
 
Saw a couple of videos recently of him, had no idea he died decades ago. Really interesting person.

There is a book : "Surely You're Joking, Mr. Feynman!" . That is "written" by Richard P. Feynman , you will enjoy the book for sure. So much funny stories but also good history from an insider when it comes to nuclear science since the beginning of the 20th century. "Adventures of a curious character". I have read it. It is a really interesting book.

I have the audiobook on hold at my local library and a print edition on hold at neighboring town's library!

I saw a video in which he explained that a Mars mission is doomed to failure, they'll never get home... IIRC. Excellent reasons why.


And this one, more impactful what with the UFO grabbage, time travel BS and other sci-fi claptrap:

I started reading it, the library wants it back, so I ordered a used copy, to arrive today. So far, I'm not finding it all that interesting, maybe 30 pages in...
Last night I chanced upon this:


Woman who's sharp and unusually loquacious and perceptive and into science in her channel (evidently) produced a 2:48:xy (i.e. almost 3 hours) video explaining why the obsession with Richard Feynman that resulted from that book really fucked up the teaching of physics at the university level, well certainly from her perspective. I only watched around 15 minutes, there's no way I am going to watch the rest. But she obviously makes good points. All these wanna be whatever guys think it is cool to be smart ass freaks because they identify with being unpredictable quirky self assertive boy-man-child.

I also discovered that there's a lot of deep fake faux Richard Feynman videos being produced lately. Often misrepresenting and screwing up what he said. There are some authentic RPF videos, part of series he did many decades ago for Cal Tech, Cornell and maybe others.
