In 1950, Nobel Prize winner Edward M. Purcell, professor of Physics, gave Ph.D. candidate Ewen the research project idea that there might be measurable radiations from the atomic particles of hydrogen floating in the Milky Way.
Edward Mills Purcell, 40 year old professor of Physics here, and Dr. Felix Block of Stanford University received the award for their development, separately, of a new method of measuring magnetic fields in atomic nuclei.
Purcell and Block arrived at the discovery, known now as the "nuclear resonance" method, independently. The Harvard and Stanford groups headed by each were never aware of the other's discoveries.
Dr. Purcell and his group succeeded in devising apparatus which enables magnetic properties to be determined to an accuracy of one part in a million.
Dutch scientists have followed up Ewen and Purcell's discovery and found, in collaboration with Harvard and the Mount Wilson Observatory, that the distance of the external galaxies from earth is actually greater than was thought.
