The Shuttle Accident & Other Man-made Disasters - Freeman Dyson - 5/11/2018

On May 11 & 12, 2018, Caltech and PMA presented Feynman 100, a celebration of Richard Feynman’s life & legacy on the occasion of his 100th birthday.
The May 11 evening event celebrated his broad contributions to science and society as a scientist, teacher, and curious character. Speakers included: Robbert Dijkgraaf, Freeman Dyson, Joan Feynman, Michelle Feynman, Janna Levin, John Preskill and Kip Thorne, Tom Rosenbaum and Leonard Susskind. The evening also included two special video presentations featuring Bill Gates and words from Richard Feynman.
Bongo drumming by Richard Feynman and Ralph Leighton.

Dyson was an amazingly captivating storyteller. Both Feynman and Dyson are dearly missed.

[@RD2564]

This less than two years before Dyson died, beautiful event to celebrate a great man Richard Feynman, nice to see Freeman Dyson in one of his last public appearances.

[@CalvinJKu]

Can't believe Freeman Dyson is still alive and able to give a talk like this....Feynmann and Dyson are both my childhood heroes and are the reason why I came to study physics. Tho I'm not doing physics anymore this sure brings back a lot of memories....

[@gautampandey3519]

Sadly not any more. Freeman would also be missed just like Feynman.

[@KienTran-lt7vs]

@@gautampandey3519 Yeah, sadly

Summary: - Freeman Dyson was one of Feynman's Cornell Students - Meeting just after the war, Feynman's wife had just died and he had just helped developed the atomic bombs dropped on Hiroshima & Nagasaka - Being a puzzle solver, Feynman enjoyed creating those bombs and his time at Los Alamos which worried him severely. On returning to civilisation, he became nihilistic and Dyson witnessed Dick's despair for humanity on the brink of Nuclear War. He knew the original purpose of the bomb development was to beat the Germans and so he regrets not leaving the project when the Germans had been defeated like some of his friends did - 3:00 "We're not going to get away with it..." - 4:00 "Feynman's Resolution - 4:25 Feynman's Appendix to the Challenger Disaster - 6:20 Feynman finds the cause of the Challenger Disaster - 7:30 Day of the Launch - 9:45 "Nature cannot be fooled..." - 10:30 Feynman's Future View, "There's plenty of room at the bottom" - 11:40 Feynman's experience with Molecular BIology - 12:30 Noah's Ark Egg

No "umms", "errs". Brilliant!

[@ukaszsurzycki845]

as Feynman said "You can't fool th Nature" but children of One Universe can be fooled.......?

[@patsyparisi2620]

Feynman destroyed those goons at NASA.

[@raykent3211]

Sticking my neck out a very long way... He spoke of sending a 1 kilometre egg , I think he meant 1 kg, to another planet. Where? What journey time? What systems (cryogenic?) inhibit development during that time without those lifeforms dying? How will they make this unnamed planet inhabitable by them? It seems little more than fantasy. I think Feynman would have been harsher in his criticism than I've just been. He was robustly pragmatic.

It was only a phantastic idea that could bring life out of the earth. Of course it has many not know problems, but all of this always begins with an idea. It was the sacred moment of revelation in human mind, like the Feynman diagrams. We known them in a ended form and ready for use. But who know how they looked the first time Feynman got the idea. 😉

Reminds me of the "Genesis Device" in "The Wrath of Khan" en.wikipedia.org/wiki/Star_Trek_II:_The_Wrath_of_Khan

[@markcollard9326]

why would they use rubber o-rings for the rocket fuel? seems logical /s

[@peterkay7458]

Mark you are right they were told to use metal swages, O-rings would have been fine (with a LOT of caveats..ie temperature surface finish...........LONG LIST) but as they also needed a paste and broke a cardinal rule which is to NEVER use two because trapped gases become trapped in the annulus....sorry long explanation...

[@hansvetter8653]

This rocket o-ring story proofs just one fact ... it was just a badly done design of a rocket construction ...

[@sharplessguy]

At the time the shuttle was developed it was the state of the art, but flawed in that to obtain funding it was severely compromised by what the military insisted it be capable of. SLS has similar issues. Congress insisted on using technology and hardware developed for the shuttle so it uses hardware developed in 1984.... Congress should not be in charge of deciding the best way to build a space craft... They aren't rocket scientists. Comparing SpaceX's Starship to Nasa's SLS or Falcon programs is like comparing a Model T to a self driving Tesla.
