Terrestrial Magnetism Selected Historic Site for Rubin/Ford Research

The American Physical Society's Historic Sites Committee has selected the Department of Terrestrial Magnetism a historic site for the pioneering research conducted by Vera Rubin and Kent Ford on dark matter. The duo made measurements of galactic rotations, which showed that galaxies do not behave as they should under  gravity. They concluded that  something else was at work--the mysterious dark matter. There will be a ceremony this spring for a plaque presentation.
