Although it does cover the scientific aspects of Einstein's life, there's way too much of a soap opera feel to it, with a huge amount of time spent on interpersonal stresses. I was really hoping for more science and less soap opera.

In 1963 President John F. Kennedy awarded (and Lyndon B. Johnson presented) Oppenheimer with the Enrico Fermi Award as a gesture of political rehabilitation. I always thought that was a nice gesture toward a great scientist who had been badly mistreated. Also, as a result of his negative testimony about Oppenheimer, Edward Teller was pretty much ostracized by the scientific community. So there was at least some measure of justice.

Facts: 64 Kg of Uranium-235 used in bomb
6.3 x 1013 Joules released (estimated) during explosion
Equation: E = mc2
Energy Efficiency: 6.3 x 1013 = m x (300,000,000)2 [where m = 7 x 10-4]
Only .1% of starting Uranium-235 is turned to energy; thus (7 x 10-4) / (.001) = .7 Kg
Conclusion: “Little Boy” contained 64 Kg of Uranium-235, but only .7 Kg of the starting mass was involved in the explosion. Furthermore, no more than .1% of the .7 Kg is converted to energy during nuclear fission. As a result, 7 x 10-4 Kg of Uranium-235 was changed into 6.3 x 1013 Joules.
Truly an astonishing example of the almost unbelievable amount of energy that can result from the transformation of an amount of uranium equivalent to about 1/3 the mass of a U.S. dime.

FYI, for anyone who is interested and gets the Decades Channel, on 7/31/17 they're showing the one-hour documentary Dr. Teller's Very Large Bomb. Check local listings for times in your locality.

I'll look for it on Decades, they're a CBS station iirc. It's still too early to see it on a schedule. Youtube only has bits and pieces of it, but I'd like to see it. Thanks for the heads-up.

Yes, thanks for the info re: Dr. Teller's Very Large Bomb. I just watched it and it's a really good documentary. It clearly explains the science behind thermonuclear bombs vs. fission bombs and also provides a lot of interesting, behind-the-scenes anecdotes re: the scientists and their activities. I highly recommend it.

PBS' NOVA current episode: Inside Einstein's Mind examines how he developed general relativity theory. It's quite Intreresting.

FYI, the character Dr. Strangelove, played by Peter Sellers in the film of the same name, was modeled satirically on Edward Teller.
