- Electrons are tiny particles that hold together the atoms in molecules. When sunlight interacts with a molecule, it first transfers its energy to the electrons. Then, as the electrons move, the molecule changes form, reshaping itself or even breaking apart. We do not fully understand how electrons affect the molecules to which they belong because it is very hard to catch them in action. Electrons move incredibly quickly, and they behave according to the peculiar laws of quantum mechanics. But now, we can follow the motion of electrons using SLAC's Linac Coherent Light Source, an accelerator that can make pulses of X-rays that are shorter than one millionth of a billionth of a second. In this lecture, I will explain how this one-of-a-kind tool allows us to watch speedy electrons as they move.
About the Speaker:
Taran Driver is an Associate Staff Scientist at the Linac Coherent Light Source (LCLS) and the Stanford PULSE Institute. He grew up in the United Kingdom, where he obtained his B.Sc. in physics and philosophy from the University of Nottingham in 2014, and his Ph.D. in biomolecular structure analysis from Imperial College London in 2019. He came to SLAC in 2019 as a postdoctoral scholar at the Stanford PULSE Institute. His research at SLAC focuses on using the unique ultrashort X-ray pulses made by the LCLS to understand how electrons move within molecules. In his spare time, he enjoys cycling and playing soccer in the California sunshine.

22:05 I attended this lecture last night in person. The SLAM competition win was well deserved for he really does have a talent for teaching at the level of the student, whatever that may be.
Very wonderful lecture.
SLAC's finest don't know how to edit a video with TH-cam's trim tool?
My guess is they are trying to learn so much that there is so little space for TH-cam trim.
Fun lecture though, I wonder if there is away to manipulate the electrons wave, by add the waves they acted more like particles but if you change that wave would it alter the electrons path? And what about the electrons action after hopping from one side to the next, then disappearing. Is the electron gaining or losing? If losing, would it be too weak to be seen? And gaining then hum, zinging off to the next adventure? Fun thoughts of a nonentity’s nonreactive perception.
if you study Basil J. Hiley and David Bohm - they prove there is an "active information" of the wave from the future that "guides" the particle. Look up Chris Dewdney's recent talk on youtube - the Pari Center - he has the computer animation of how these waves work. The "weak measurement" experiments actually show this in reality. thanks
