What is john s. pratt?

John S. Pratt (1921-1995) was an American physicist and professor, known for his contributions to the field of solid state physics. He was born in Evanston, Illinois, and earned his PhD from the University of California, Berkeley in 1948.

Pratt worked at the Massachusetts Institute of Technology for many years, where he conducted research on the electronic properties of semiconductors and insulators, as well as the physics of disordered systems. He was a pioneer in the use of neutron scattering techniques for studying solids, and his work helped to establish the field of neutron scattering in the United States.

In addition to his scientific research, Pratt was also known for his efforts to promote science education and outreach. He directed the Summer Institute for High School Students at MIT, which provided talented high school students with the opportunity to study science, mathematics, and engineering. He also served as President of the American Association of Physics Teachers.

Pratt received many honors and awards throughout his career, including the Oliver E. Buckley Condensed Matter Prize in 1970 and the National Medal of Science in 1987. He died in 1995 at the age of 73.
