||Carson Dunning Jeffries (d. October 18, 1995) was an American physicist. The National Academies Press said that Jeffries "made major fundamental contributions to knowledge of nuclear magnetism, electronic spin relaxation, dynamic nuclear polarization, electron-hole droplets, nonlinear dynamics and chaos, and high-temperature superconductors." He was noted for being the first to observe the isotropic spin-spin exchange interaction in metals (also known as the Ruderman-Kittel interaction). He also discovered methods for the dynamic nuclear polarization by saturation of forbidden microwave resonance transitions in solids. He also discovered the existence of giant electron-hole droplets in semiconductors. | ||Carson Dunning Jeffries (d. October 18, 1995) was an American physicist.

1791: Polymath Charles Babbage dies. He constructed mechanical computers which anticipated the concept of programmable digital computers.
1919: Statistician and educator George E. P. Box born. He will be called "one of the great statistical minds of the 20th century".
1931: Inventor, engineer, and businessman Thomas Edison dies. He developed the light bulb and the phonograph, among other inventions.
1945: The USSR's nuclear program receives plans for the United States plutonium bomb from Klaus Fuchs at the Los Alamos National Laboratory.
2017: Publication of Bioautography of a Chlorophyll Molecule generates new interest in organic golems.
