Apr 30, 2024 · For his intuition, dedication, creativity, and curiosity, Millikan is a paragon of 20 th century physics, and an enduring inspiration for generations of Techers. On the occasion of the 2016 Nobel Prize announcements, the Caltech Archives is pleased to present an illustrated account of Millikan's road to Stockholm. -EP. Visit the online exhibit.
6 days ago · Robert A. Millikan (1868–1953) was the second American to win the Nobel Prize in physics. At the peak of his influence, no scientist save Einstein was more admired by the American public. Millikan, the head of the California Institute of Technology (Caltech) during its first 24 years, oversaw its rapid growth into one of the leading scientific institutions of the world. However, in response ...

3 days ago · Robert A. Millikan is credited with determining the charge of the electron when he conducted oil drop experiments with Harvey Fletcher. Ernest Rutherford proved the existence of the atomic nucleus through an ingenious set of experiments that involved relatively simple gold foil and ionizing alpha radiation.
5 days ago · August 6, 1945. The United States Army Air Force dropped an atomic bomb on Hiroshima, Japan. The bomb, named “Little Boy,” used uranium-235 processed at Oak Ridge for its implosion assembly. This was followed three days later with a second atomic bomb, “Fat Man,” dropped on Nagasaki.
3 days ago · Robert Millikan. The electron's charge was more carefully measured by the American physicists Robert Millikan and Harvey Fletcher in their oil-drop experiment of 1909, the results of which were published in 1911. This experiment used an electric field to prevent a charged droplet of oil from falling as a result of gravity.
