We're going to need a bigger blackboard

Watch SLAC theorist Lance Dixon write out a new formula that will contribute to a better understanding of certain particle collisions.


Speak physics: What is a cross section?

Cross sections tell physicists how likely particles are to interact in a given way.


A GUT feeling about physics

Scientists want to connect the fundamental forces of nature in one Grand Unified Theory.


Of symmetries, the strong force and Helen Quinn

Scientist Helen Quinn has had a significant impact on the field of theoretical physics.


Quantum entanglement

Through ‘spooky action at a distance,’ the properties of two systems remain correlated even after they are separated.


The great physics quest

In their search for fundamental truths, particle physicists have a lot in common with explorers everywhere. 


A model partnership

Bucking the “ivory tower” stereotype, particle theorists dive into Large Hadron Collider experimental searches and come up with a new way to look at the data.


Lylie Fisher: Beauty bubbles through

For artist Lylie Fisher, particle physics is much more than a field of science. It is art: "Like art, particle physics deals with the invisible," says Fisher. "One portrays emotional and spiritual experiences; the other studies unseen matter and energy.



Particle physics has been confronted with serious challenges in recent years, especially for the operation of colliders. Yet 2006 promises to be a great year for research in particle physics as well as photon science, and many exciting projects are underway.


Stephon Alexander: Theory by day, saxophone by night

By day, Stephon Alexander theorizes about the effects of dark matter in his office at SLAC. By night he plays tenor saxophone in a San Francisco jazz club.
