Einstein Wrote Back is a memoir by Canadian physicist John Moffat that documents his encounters with various other famous physicists, including Niels Bohr, Albert Einstein, Erwin Schrödinger, Fred Hoyle, Wolfgang Pauli, Paul Dirac, Abdus Salam, and J. Robert Oppenheimer, as well as his work at Imperial College London, Princeton University, CERN, and the University of Toronto. The book's title comes from a series of letters Moffat exchanged with Einstein early in his life, which inspired Moffat to continue studying physics.
