Six Questions Physicists Ask when Evaluating Scientific Claims in the 21st Century

Six Questions Physicists Ask when Evaluating Scientific Claims in the 21st Century Not all scientific claims are equal. How can you tell if a discovery is real? In 2011, scientists on the OPERA experiment announced an observation they couldn’t explain: neutrinos that seemed to be traveling faster than the speed of light. Their analysis methods...

What is the Electroweak Force?

What is the Electroweak Force? Electromagnetism and the weak nuclear force are two distinct fundamental forces. That wasn’t always the case. How many fundamental forces are there in our universe? For particle physicists, answering this question can be tricky. Of course, there’s the force of gravity, which keeps us from floating out of our seats....
