00:20:12 Ambar Rodriguez: Hello I'm a student from University of Puerto Rico, Mayaguez 00:20:29 Ambar Rodriguez: Undergraduate in physics 00:20:33 Jacob Zweifel: I am a student from University of Rochester, NY 00:31:53 Karan Kumar: Are neutrinos second most abundant in the visible mass? and also what is the most abundant? 00:54:45 Sebastian Ritter: at least 2! 00:54:58 Grace Kowalski: 4! 00:55:00 Karan Kumar: 3 00:56:48 Mary Bishai: Grace wins this round 00:58:10 Andrea Houck: P=0 no oscillations 00:58:14 Timothy Topolski: p = 0 01:04:54 Karan Kumar: right electron 01:04:59 Grace Kowalski: Electron ring on right 01:12:37 Karan Kumar: what is cp violation? 01:20:36 Ambar Rodriguez: Measuring the loss of energy in neutrino production? 01:22:06 Mary Bishai: @Karan - the study of cosmology and in particle the remnants of the shock wave from the big bang also put a limit on the neutrino mass. But its a limit. 01:22:42 Timothy Topolski: How far does the absolute mass typically deviate from the effective mass? 01:58:48 Grace Kowalski: Thank you both for everything!
