It's fascinating listening to these true geniuses talk about each other. Feynman, Bethe, Dyson etc... One can only imagine the conversations they had
The Bethe-Feynman efficiency equation he refers to at 0:27 is:
Eff=(1/γ-1)E2)*α_max^2*R_crit^2(𝛿*(1+3*𝛿/2)/(1-𝛿)
Where γ is the thermodynamic exponent of a photon gas, E2 is the prompt energy density of the fuel, α is V_n (neutron velocity) / λ_mfp_tot (Total reaction mean free path), R_crit is the critical radius and 𝛿 is the excess supercritical radius ((R_core-R_crit)/R_Crit).
Bethe is a true legend, just like Feynman. Not as much of a charismatic character, but arguably made just as many if not more important contributions. He seems like a cool dude as well
Yes, indeed. Devoid of pretension, just straightforward and intellectually honest, but powerful at the same time.
Freeman Dyson says Bethe made Cornell a welcoming place
A lot of Feynman's "charisma" was contrived. As Gell-Mann said, "he became obsessed with creating anecdotes about himself."
It is a joy to listen to the anecdotes of experiences shared by these great scientists. If I live to be 100, I will be proud to say that I once shared the earth with them - Bethe, Feynman, and Freeman Dyson - even though I myself am not a scientist, nor did I ever meet one of the people that I listed.
I met Dr. Bethe in the men's room 2nd floor UCI physics department. I'm taking a pee and look over and say, "YOUR HANS BETHE!!!!!!!". I invite him over for an awesome party that night with the undergrads in the department, but he declines with 'I have to be in Santa Barbara tonight'. I go over the student office and yell 'I just met Hans Bethe and invited him to our party'. He probably went to the other professors and went 'I just got invited to an awesome party'.
Seriously?
@@thelamergamer1894 - Why not? He gave talks now and then at various universities. I heard him at the University of Washington in the 1970s.
I have began to think that Hans, with his ability to listen,recognise the talent, and make sure that talent was not snubbed by the scientists/politicians with the actual power (Oppy), has been more central to the success of Manhattan's project than is let believe.
It is very much about how one uses the resources available.
Bethe: A man who could just sit down and calculate almost everything, no errors just straight up pounding the numbers for hours. To take a notion from Dune: he was the closest thing to a mentat we ever had.
Wonderful! We need more history like this.
Such a shame bethe doesn't get more recognition. The stories of his mental math are astounding
You can watch many hours of Hans Bethe at the Web of Stories video archive - see uploading information above...
Very interesting. I wish there was more on Dr. Bethe.
Hans you're
One of the world's greatest!

Best nuclear physicist
Feynman was a tinkerer and not just a pencil pusher. he worked on repairing vacuum tube radios when he was younger so building a computer with instructions wasnt really outside his skill set.
Yes, especially since he would have just been hooking up the various modules. He didn’t build the thing from scratch.
Thank you for posting this. I always thought Bethe was an important moral scientist.
The man the myths the legend. The battleship talking about the mosquito.
lucky Hans.

@knight3481 please just calm down
Einstein Oppenheimer
This is nothings. After two solid weeks of hard work, 10 hours a day, 7 days a week, i managed to get my laptop to work completely by myself and its an IBM too.
On weeks one i flipped it open. Week two i pressed the on button. Hardest two weeks of my life
Couldn't swing a dead cat at los alamos without taking out a couple stalinist agents.
bethe was best of last century.better than dirac and einstein.
Nonsense!
Paul Maurice - It isn’t a contest. Each made contributions of great importance to physics.
Why are you getting emotional man
I don’t believe the great physicists can be ranked. They were unique individuals and each made contributions which were important to the development of physics. Just remember each for his contribution.
Someone get this man some teeth!
I think his teeth are fine, at least they look fine to me. Guess living appx a century can affect ones speech in a variety of ways.
Great minds no doubt, but I wish they had built something more useful to mankind !
you may want to rethink your thought.
There has not been a world war since. Perhaps the best invention ever.
Would you say this if your country had been at the receiving end ? Not to mention, the number of rogue states" that have the potential to use it.
Again, there has not been a world war since, and yes we were on the receiving end. We didn't want in. We were attacked. And an international coalition came together to end world wars. More Japanese died in a single conventional bombing raid than either Hiroshima or Nagasaki. The one plane, one bomb events stopped the madness of kamikaze warfare on a global scale.
What's going on in the world today is nothing short of a World War. It's just not been labelled yet. And so far, we've been lucky there's been no nukes...yet. Matter of time I think, unfortunately.
I was expecting him to speak less painful English, Wikipedia says he was fluent. I would almost prefer if he spoke German and I could use subtitles if necessary to follow.
His English is perfect. He is fluent. You're complaining about his accent. That's your problem not his.
