Abstract:   Electron cryo-microscopy (cryo-EM) has already had a revolutionary impact on single-particle structure analysis (SPA) and cell biology, but still falls far short of its theoretical capabilities. Here, we maximize image contrast by combining the laser phase plate (LPP)...

Abstract:   I will describe my early experiences at SLAC, beginning in the late 60’s with the electron-proton scattering program which discovered point-like structure in the nucleon. I will then move to the beginnings of SPEAR and the November Revolution...

Abstract:   Particle colliders have been the workhorse tool for particle physics since they were invented over 60 years ago. Forward particles are those that are produced at colliders and then travel in a direction close to the beamline. For...

No Colloquium on 05/25. We will resume the regular series soon.

Abstract:   The United States has not conducted an explosive nuclear test since 1992, yet confidence in its nuclear deterrent has been maintained through the science-based Stockpile Stewardship Program. Over the past three decades, this effort has driven major advances...

Abstract:   Microelectronics spans a broad stack from materials and devices to circuits, architectures, and integrated systems, all of which are essential to modern scientific instrumentation. Across fields such as photon science and high-energy physics, advances in microelectronics have enabled...

Abstract:   The origin of cosmic acceleration remains an open question: is it caused by a dark energy and if so, what are its properties? Or is our theory of gravity incomplete on the largest scales? These questions have driven...

Abstract:   I will talk about GammaTPC, a new MeV-GeV gamma-ray instrument based on liquid argon time projection chamber (TPC) technology.  The MeV sky in particular is poorly measured, largely due to instrumental challenges. A transformative instrument in this energy...

Abstract:   The promise of quantum is real, and we are beginning to see where this technology can have the greatest impact. Decades of quantum research and development point to one primary class of practical application for quantum computing next...
