Physicist Richard Feynman assist produce the atomic bomb , shared aNobel Prizefor his workplace on quantum electrodynamics , and helped to visualise out the source of the space birdie Challenger explosion .

But he was also subject to scrutiny by the U.S. Federal Bureau of Investigation , as it sought to uncover communist sympathizers during the 1950s .

Physicist Richard Feynman won the Nobel Prize, worked on the Manhattan Project and was featured on a U.S. Postal Service stamp.

Now , document from Feynman ’s FBI file have been unblock andposted at MuckRock.com , a land site dedicated to public records requests .

The FBI began maintain an centre on Feynman after other penis ofthe Manhattan Project , which build the first atomic dud , turn out to be Soviet spies , including Klaus Fuchs , the project ’s primary physicist . The documents , 361 pages , book statement after financial statement from the physicist ’s friends and colleagues , mostly praise Feynman for his brilliance , trustiness and allegiance to the area . [ Top 10 Mad Scientists ]

The document available at MuckRock contingent , for exemplar , how in 1958 Feynman , then at Caltech , received an invitation from the Soviet Union to attend a cathartic conference in Moscow . After discovering this invitation by sifting through the Soviet ambassador ’s crank , the FBI began looking into his plans .

Feynman , meanwhile , delayed accepting it and sought counseling from the State Department , which forward his missive to the FBI but waited month before responding , accord to MuckRock .

In 1958 , the FBI conduct a routine scope probe on Feynman when he was being considered for President Eisenhower ’s Science Advisory Committee . Reports and memos , including newsprint articles mentioning the physicist , reveal ’s brillianceas a physicist and some of his personal interests and drawback .

For illustration , an FBI account see July 21 , 1958 , base on information from a Cornell faculty member and colleague of Feynman ’s stated that Feynman " was one of the outstanding physicist in this country and in spitefulness of some of his personal riding habit , he felt that there was no interrogation touch his loyalty , duty , discretion , or companion . "

The study went on , " He posit that Professor Feynman was an accomplished jazz drummer and believed that this pursuit , in the eyes of some mortal , was not in continue with Feynman ’s role as a professor of physics . "

In a note to the theater director of the FBI , dated July 29 , 1958 , Special Agent - in - Charge ( SAC ) Los Angeles notes inside information from an LA Times article from two years prior , regarding his relations with his married woman : " The appointee ’s wife was granted a divorce from him because of appointee ’s constantly work calculus problems in his pass as soon as awake , while driving car , model in living way , and so away , and that his one hobby was playing his African drum . His ex - married woman reportedly evidence that on several affair when she unwittingly disturbed either his tartar or his drum he fly into a violent craze , during which time he choked her , threw pieces of bric - a - brac about and smash the article of furniture . "

ostensibly , another of Feynman ’s far-out traits : He was a star atcracking safesand pick locks , accord to the released document .

To create the optical atomic clocks, researchers cooled strontium atoms to near absolute zero inside a vacuum chamber. The chilling caused the atoms to appear as a glowing blue ball floating in the chamber.

The gold foil experiments gave physicists their first view of the structure of the atomic nucleus and the physics underlying the everyday world.
