Jerry Friedman, a professor of physics at M.I.T. and a Nobel laureate, will deliver a public lecture Nov. 3 at 10 a.m. at the Ted Constant Convocation Center at Old Dominion University. His topic is "Are We Really Made of Quarks."

Also on Nov. 3, Friedman will host an open forum for students, teachers and faculty members from 2:30 -4 p.m. in the Potomac River Room of Webb Center.

From 1967 to 1975 Friedman and colleagues from the Stanford Linear Accelerator Center and California Institute of Technology accomplished measurements of inelastic electron scattering from the proton and neutron, which provided the first direct evidence of the quark sub-structure of the nucleon. The results of this work led to the Nobel Prize in Physics in 1990 for Friedman, Henry Kendall and Richard Taylor.

In 1964, quarks were proposed as the basic building blocks of matter. After efforts to prove the theory failed, however, most physicists rejected this model until modern high-energy electron scattering experiments were able to probe the interiors of the proton and neutron.

The discovery of quarks changed our view of the basic structure of matter and altered the path of particle physics.
