Hans Bethe, the physicist who explained and applied the nuclear and thermonuclear reactions both in the stars (carbon cycle) as well as in the bombs (Manhattan project), died in Ithaca at the age of 98... It's sad but many of us would be happy to live for ninety-eight years.
Hans Bethe was also the left-wing counterpart of the right-wing Edward Teller (*1908 Budapest - +2003 U.S.)
Ralph Alpher is alive and well. George Gamow died in 1968. Delter is a campus in Beijing.
