1. The making of a proton, neutron, and electron. By Garrett Belew, Roig Wilson, Eric Saxen, Anna Nguyen, Haley Mindurp

2. Subatomic Particles Atoms are made of protons, neutrons, and electrons. Protons, neutrons, and electrons are made up of smaller particles called quarks and leptons.

3. Quarks A member of subatomic particles that interact with strong forces that are believed to be the fundamental constituents of matter. Quarks associates with one another by a strong force to make protons and neutrons. Quarks are 14.156 times bigger than a lepton

4. Leptons Particles such as electrons that don’t participate in the strong interactions and are not seen within the nucleus

5. Murray gell-man Dr. Murray Gell-man, was born on September 15 th, 1929 in New York city Dr. Gell-man attended Yale university at age 15, he obtained his B.S. at Yale in 1948 and his Ph.D. in 1951 at the Massachusetts institute of technology In 1952 he became a member of the institute for advanced study, during 1952-53 he was a instructor at the university of Chicago, from 53-54 he was assistant professor and in 1954 he was appointed associate professor for research on dispersion relations

6. Dr. Murray Gell-man’s work Dr. Gell-man found that particles such as a proton or neutron, are composed of fundamental building blocks, that he named “quarks”, with very unusual properties. In 1959 he was awarded the Dannie Heinemann prize of the American Physical Society. Dr. Murray Gell-man is one of today’s most prominent scientists.
