Hans Bethe lecture, My Relation to the Early Quantum Mechanics, November 21, 1977

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 [e-mail] if you wish to use or quote.
Audio and video quality decrease at a few points in the video.

Old world brilliance on display…humbling when we think of our intellectual world today…

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

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

He deserves a biopic from Christopher Nolan as a tribute.

Anybody but Nolan

Surely the sound could be better synchronised with the video? It is minutes off.

[@Drbob369]

Good work

[@michaelgonzalez9058]

Like a collider

[@jcriley7695]

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!

[@donclay3511]

Probably can't do anything about it now, but the sound is way ahead of the video.

[@jayachanderrao4370]

There is a delay in audio and video, which needs to be corrected

[@gibbogle9486]

It is off by minutes. It makes his talk very hard to follow.

[@tedstriker5991]

Make sure both left and right channels have equal volume audio when you post. Easy fix in editing software.

[@cowboybob7093]

Headphone wearer here, that's nothing compared to how out of sync the picture and sound were, but I'm with you

[@tedstriker5991]

@@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.

[@cowboybob7093]

@@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.

What about the computer

Isn't "the first Born approximation" what G-d did to Egyptians?

There are. Other equipment

It's okay, just don't use headphones and play slightly less fast
