She is a YouTuber; she uploads videos to her YouTube channel Physics Girl explaining various physical phenomena. She worked in partnership with the PBS Digital Studios from 2015 until 2020, when she discontinued her partnership. [5]
Other witnesses scheduled for Friday include engineer Dave Dyer of the University of Washington Applied Physics Lab and Patrick Lahey of Triton Submarines. The hearing is expected to resume next ...
Sabrina Gonzalez Pasterski (born June 3, 1993) is an American theoretical physicist from Chicago who studies high energy physics. [2][3] She describes herself as "a proud first-generation Cuban-American and Chicago Public Schools alumna". [4] Her first few months at Harvard's Center for the Fundamental Laws of Nature (2014) resulted in ...
The 2023 Nobel Prize in physics has been awarded to a team of scientists who created a ground-breaking technique using lasers to understand the extremely rapid movements of electrons, which were ...
A simulated particle collision in the LHC. The safety of high energy particle collisions was a topic of widespread discussion and topical interest during the time when the Relativistic Heavy Ion Collider (RHIC) and later the Large Hadron Collider (LHC)—currently the world's largest and most powerful particle accelerator—were being constructed and commissioned.
Axel Scherer is the Bernard Neches Professor of Electrical Engineering, Physics, and Applied Physics at the California Institute of Technology. He is also a distinguished visiting professor at Thayer School of Engineering at Dartmouth College. He is known for fabricating the world's first semiconducting vertical-cavity surface-emitting laser ...
The Z Pulsed Power Facility, informally known as the Z machine or Z, [1] is the largest high frequency electromagnetic wave generator in the world and is designed to test materials in conditions of extreme temperature and pressure. It was originally called the PBFA-II and was created in 1985. Since its refurbishment in October 1996 [2] it has ...
Quantum field theory. In quantum field theory, the quantum vacuum state (also called the quantum vacuum or vacuum state) is the quantum state with the lowest possible energy. Generally, it contains no physical particles. The term zero-point field is sometimes used as a synonym for the vacuum state of a quantized field which is completely ...
