3. April 2012: Mark Hamilton, a high-school intern in our team, has been awarded the I. I. Rabi scholarship and offered admission into Columbia University. Founded in 1989 by Columbia College and faculty of the science, the Rabi Scholars Program was established in memory of 1944 Nobel Laureate and Columbia physics faculty member I. I. Rabi. A small number of incoming first year Columbia College students who demonstrate exceptional promise in the sciences are chosen to be Rabi Scholars, and the program seeks to support and encourage these talented young scientists by providing research opportunities throughout their undergraduate careers.
