Atomic engineering engineering. The atomic character could be the atomic spin (e.g. in Nuclear magnetic resonance and quantum computing applications), atomic position (e.g. Optical lattice), atomic mass (e.g. atomic power), etc. The creation of the atomic bomb by Julius Robert Oppenheimer, the "Father of the atomic bomb", is based on atomic engineering. Oppenheimer was a university professor and physicist at the University of California, Berkeley. Richard Feynman, in his famous 1959 lecture "There's Plenty of Room at the Bottom" on the trend of miniaturization, envisioned: Most practices of nanotechnology and materials science today have foci distinct from Feynman's ultimate vision of manipulating
Soviet atomic bomb project research programs. In April 1942, Flyorov directed two classified letters to Stalin, warning him of the consequences of the development of atomic weapons: "...the results will be so overriding [that] it won't be necessary to determine who is to blame for the fact that this work has been neglected in our country." The second letter, by Flyorov and Konstantin Petrzhak, highly emphasized the importance of a "uranium bomb": "it is essential to manufacture a uranium bomb without a delay." Upon reading the Flyorov letters, Stalin immediately pulled Russian physicists from their respective military services and authorized an atomic bomb project,
