In April 1961 there was a big Centennial Celebration at MIT. Naturally it was a proud, joyous, even intoxicating Celebration. At the week-long event there was a panel discussion on “The Future of Physics”, chaired by Francis Low, with four speakers in the following order:

(As told by Yang Chen-Ning)
Enrico Fermi had a very interesting way of working on a manuscript. When corrections were to be made, he would cut out portions to be deleted and scotch-tape on additions. As a result, some pages became long rolls of paper.

When Paul Dirac was awarded the Nobel in 1933, he wanted to refuse it, as he hated advertising. However, Rutherford managed to persuade him to accept the award – he simply explained that a refusal would be an even bigger advertisement.
He then agreed to go to Stockholm.

In the fall 1954, Igor Dzyaloshinskii became a graduate student at the Institute for Physical Problems (IPP). This allowed him to pass security.
At the time Igor arrived at the Institute of Physical Problems, there was still some work in the nuclear project (H-bomb).

In early 1951, Edward Teller and Stanislaw Ulam developed the Teller-Ulam configuration, a design for a practical hydrogen bomb. This design utilized radiation from a fission primary to compress and ignite a thermonuclear secondary.
