Enrico Fermi
Fermi wrote a paper "On the Origin of Cosmic Radiation" in which he proposed that cosmic rays arose through material being accelerated by magnetic fields in interstellar space, which led to a difference of opinion with Teller. Fermi examined the issues surrounding magnetic fields in the arms of a spiral galaxy. He mused about what is now referred to as the "Fermi paradox": the contradiction between the presumed probability of the existence of extraterrestrial life and the fact that contact has not been made.
Toward the end of his life, Fermi questioned his faith in society at large to make wise choices about nuclear technology. He said:

On the second floor of section V is the "Fermi Room," where Enrico Fermi is said to have lived while working on the Manhattan Project in the 1940s. It is rumored that he chose that room because it had its own bathroom with tub; though the bathroom remains, the tub was replaced with a shower in 2008. Linked to the Fermi Room is the Fermi Blackboard, which is said to be the same blackboard Fermi used to do his calculations, although this may be an urban legend. This possibility does not, nevertheless, detract from many students' desire to possess it.
