Not just atomic weapons but also the atomic submarine and many other inventions. were from Jews. My dad later created laser communication between satellites for the Star Wars SDI program when he was working at TRW.
Even in the university were I studied, Polytechnic Institute of New York University, most of the professors were Jewish and some German.
(Prof. Arnold is Jewish. My Prof in Physics is Van Wagnen. There were a few English and one Irish professor. A lot of graduate students were from China. ) All in all if you look at just the professors the majority in Physics and Engineering and Chemistry and Math were Jewish.
[And they tend to be real hard nosed people. Slave drivers you might call them. I had one girl friend, Noel, who published papers together with Arnold. and she was brought to excellence by his hard driving attitude but she was also being worked way beyond her limits. Altogether it was not a bad deal for her. To get your name of five research papers while still an undergraduate student is not bad.] There were also lots of Israelis that I ran into.
