By WILLIAM J. BROAD
Hans Bethe, who discovered the violent force behind sunlight, helped devise the atom bomb and eventually cried out against the military excesses of the cold war, died late Sunday. He was 98, among the last of the giants who inaugurated the nuclear age.
His death was announced by Cornell University, where he worked and taught for 70 years. A spokesman said he died quietly at home.
...
For nearly eight decades, Dr. Bethe (pronounced BAY-tah) pioneered some of the most esoteric realms of physics and astrophysics, politics and armaments, long advising the federal government and in time emerging as the science community's liberal conscience.
During the war, he led the theoreticians who devised the atom bomb and for decades afterwards fought against many new arms proposals. His wife, Rose, often discussed moral questions with him and, by all accounts, helped him decide what was right and wrong.
Dr. Bethe fled Europe for the United States in the 1930's and quickly became a star of science. As a physicist, he made discoveries in the world of tiny particles described by quantum mechanics and the whorls of time and space envisioned by relativity theory. He did so into his mid-90's, astonishing colleagues with his continuing vigor and insight.
In a 1938 paper, Dr. Bethe explained how stars like the Sun fuse hydrogen into helium, releasing energy and ultimately light. That work helped establish his reputation as the father of nuclear astrophysics, and nearly 30 years later, in 1967, earned him the Nobel Prize in physics. In all, he published more than 300 scientific and technical papers, many of them originally classified secret.

Just last week I posted about the fact that Bethe was still alive and kicking. He was one of the truly great physicists of our time. If you want a monument, look up at the stars tonight, since he is the one that explained why they shine. Say hello to Einstein and Feynman for me Hans. :cry:

6. Now that's a gathering of minds I'd love to witness |
|
Feynman, Einstein, Bethe. Throw in Heseinberg, and Bohr for good measure. The conversation would be illuminating to say the least :)

4. Hans Bethe was a gentleman. |
|
I was writing for my university newspaper and I phoned him one day to report on a United Nations event he was involved in, maybe UNESCO or UNICEF, I have to look it up... He graciously invited me to the event's dinner.
My university experiences had always been pretty patchy, I'd been asked to leave the university twice ("to get my act together," as one dean explained it...) and I was sort of hanging around waiting for my third and final strike, after which I would become one of those freakish homeless guys living in a culvert and in the university library.
But Dr. Bethe became a friendly face to me, remembered my name, and was one of the people who taught me how I shouldn't burn my bridges.
By sunlight or by starlight, I will always remember him. He figured out where the light came from.
