Q&A
Description:
Delve into the fascinating world of neutrino physics in this comprehensive lecture on neutrino oscillations and the solar neutrino puzzle. Explore the history of neutrino discovery, from Fermi's theory of beta decay to the groundbreaking experiments that led to the resolution of the solar neutrino problem. Learn about the proton-proton chain reaction in the sun, various neutrino detection methods, and the key experiments like Davis' chlorine experiment, Kamiokande, and the Sudbury Neutrino Observatory. Understand the concept of neutrino oscillations and how it solved the long-standing mystery of missing solar neutrinos. Discover the connections between particle physics and astrophysics, and gain insights into the Nobel Prize-winning research that revolutionized our understanding of neutrinos and their behavior.
