- Theodore Ducas begins the lecture event, held at MIT on November 21, 1977, by introducing Victor Weisskopf, who, in turn, introduces his longtime collaborator and friend, Hans Bethe. Bethe's lecture covers his experiences with early quantum mechanics. Subjects include: The limited early understanding and teaching of quantum mechanics at the University of Frankfurt in the 1920s; Bethe's eventual transfer to the University of Munich where he continued to develop his understanding of quantum mechanics with Arnold Sommerfeld; How his education was influenced by Erwin Schrödinger’s work; Werner Heisenberg’s matrix theory; Louis de Broglie’s wave theories; P.A.M. Dirac’s conclusions about light waves and light quanta; Bethe's thesis work on electron scattering. Other scientists mentioned are Enrico Fermi, Felix Bloch, Wolfgang Pauli, and Paul Peter Ewald. At the end of his lecture, Bethe takes questions from the audience and Weisskopf tells a story about Max Planck.
This video recording contains the second lecture of two in the Quantum Mechanics series, held at the Massachusetts Institute of Technology in the 1970s. The series was organized by Theodore Ducas, (Professor of Physics emeritus, Wellesley College). The series titles are as follows: Part 1: “My Life as a Physicist,” Victor Weisskopf, January 13, 1977; Part 2: “My Relation to the Early Quantum Mechanics,” Hans Bethe, November 21, 1977.
The video forms a part of the Niels Bohr Library & Archives Collections, AV 2022-2705. Please contact nbl@aip.org if you wish to use or quote.
Audio and video quality decrease at a few points in the video.

It is a great lecture by a great person to whom we owe much for our present understanding of theoretical physics.

Old world brilliance on display…humbling when we think of our intellectual world today…
Professor Bethe, was an interesting man-I saw him at UCR and asked him a question about his attempted application of the standard model to the problem of solar phenomena.
You all have done greatest service to humanity in bringing up & presenting to the World facts & truth of natural mathematical sciences directly from the context of the true heroes of 20th Century & 21st Century Science, Engineering & Technology personalities: both the pillars, the pioneers, the mathematical scientists themselves, including the students very much alive historically in the true spirits of human knowledge & understanding - with sense of life, wits & humors. Thank you AIP, Thank you MIT, Thank you ALL. - Gpw Bernard Bautista
Thank you so much.
A wounderfull lecture
nice footage
Hans u are a gem to remind me of the state
Good work
Surely the sound could be better synchronised with the video? It is minutes off.
He deserves a biopic from Christopher Nolan as a tribute.
Anybody but Nolan
There is a delay in audio and video, which needs to be corrected
It is off by minutes. It makes his talk very hard to follow.
13:00 is hilarious. Scan back a few minutes to the guy who brings him out and it will make sense. It's a good one!
Make sure both left and right channels have equal volume audio when you post. Easy fix in editing software.
Headphone wearer here, that's nothing compared to how out of sync the picture and sound were, but I'm with you
@@cowboybob7093 I wear only the right earphone and try to fall asleep. Pretty annoying. So many posters of old videos don't even have the minimal audio consideration.
@@tedstriker5991 OOF - Yeah, the one-earphone syndrome, me too sometimes for sure. Music tends to alert me so I have lectures bookmarked for drifting off.
Like a collider
❤❤❤
Probably can't do anything about it now, but the sound is way ahead of the video.
Is one of many
Isn't "the first Born approximation" what G-d did to Egyptians?
What about the computer
Why quibble being all correct
I was watching
There are. Other equipment
Interesting where people laugh and where they don't.
Audio level is too low to understand the content.
It's okay, just don't use headphones and play slightly less fast
There is now
When I used the hydron collideri jumped 700billion
Decade millenniums for thebody
Ted Ducas now retired. Life is short.
