Measuring up: an electron scattering experiment yields a small proton radius. (Courtesy: Jefferson Lab) For nearly a decade the size of the particle that makes up the bulk of the universe’s visible ...

A study published in Nature has established a new benchmark in modeling the universe's most extreme events: the collisions of black holes and neutron stars. This research, led by Professor Jan Plefka ...

Scattering takes place across the universe at large and miniscule scales. Billiard balls clank off each other in bars, the nuclei of atoms collide to power the stars and create heavy elements, and ...

A cloud of ultracold atoms is like a motel with a neon “no vacancy” sign. If a guest at the motel wants to switch rooms, they’re out of luck. No vacant rooms means there’s no choice but to stay put.

Messenger from the dark side: Dark matter may interact with normal matter via a hypothetical particle known as a dark photon. (Courtesy: Shutterstock/80's Child) A new analysis conducted by an ...

The objective of this chapter is to introduce the concept of radar cross section and the fundamentals of electromagnetic scattering in an overview fashion so that the reader may then delve into the ...

Arvin examines what happens when you keep cutting paper: which chemical bonds are broken and which remain. The video demonstrates that while scissors can sever molecular bonds in materials, there is a ...
