Professor Jerome Friedman was awarded the Nobel Prize for the discovery of quarks – the smallest known particles in nature. He has been working at MIT for 65 years now, and one of his teachers was Enrico Fermi – one of the fathers of the first nuclear reactor and the atomic bomb. What was he like in person? What was the most important thing he learned from Enrico Fermi? And when will we learn more about quarks? He answered all this in Hyde Park Civilization.
