How the Higgs Mechanism Give Things Mass
Fermilab physicists really care about the mass of the W boson. They spent nearly a decade recording collisions in the Tevatron collider and another decade analysing the data. This culminated in the April 7 announcement that this obscure...

Electroweak Theory and the Origin of the Fundamental Forces
Our universe seems pretty complicated. We have a weird zoo of elementary particles, which interact through very different fundamental forces. But some extremely subtle clues in nature have led us to believe that the forces of nature were...

Quantum Gravity and Gravitons: The Search for a Theory of Everything
We've gone through some of the main advancements in modern physics, which brings us to the here and now! What are physicists currently working on? One huge area of interest is developing a quantum field theory for the gravitational...

Quantum Chromodynamics (QCD)
Electromagnetic force down, three more forces to go! Which one is next? Why it's the strong nuclear force, famous for keeping atomic nuclei together. What kind of particles will be involved in this quantum field theory? Let's find out.

Quantum Electrodynamics (QED)
In our study of physics, we have become aware of four forces, and the fields that mediate them. Once we got deep into quantum theory, we started to realize that these forces are not mediated by fields at all, but rather by quanta. That's...

The Physics of Superconductors
How a superconductor works. Everything from the physics and some of the history as well. Superconductors were discovered in 1911 by Heike Kamerlingh Onnes. It was discovered because it was made possible to liquefy helium which produced...

The Standard Model of Particle Physics
Once you start learning about modern physics, you start to hear about weird particles like quarks and muons and neutrinos. What are all these things? Why are there so many? How do we know they exist? What do they do? Within lies the...
