Central to all of the equations of relativity is the Lorentz factor, also known as gamma. In this 8-minute video, Don Lincoln shows you a simple way to derive gamma and explains its physical significance.

Fermilab scientist Dmitri Denisov recalls how, during autumn months, DZero experimenters occasionally collided with critters seeking warmth in the underground areas by the detector.

The next generation

Fermilab is closely tied to the local community, drawing students and teachers through its public engagement programs. Some of the lab’s younger guests are impressive, as illustrated by an encounter that scientist Sowjanya Gollapinni shared with a visiting middle school neighbor.

First-day shakes

Aria Soha was working on her very first shift as a particle accelerator operator when the machines appeared to suddenly lose their stores of particles. Rookie mistake or force majeure?

One of the most counterintuitive facts of our universe is that you can’t go faster than the speed of light. Why is this so? Don Lincoln explains in this 8-minute video.

The vox and the hound

One day in the 1980s, Fermilab staff working on the Tevatron heard the faint sounds of a dog barking over the telecommunication system. Elvin Harms tells the story of how they located the source of the mysterious sound.

Scientist Brendan Casey was a scientist on the DZero experiment when he experienced the most humbling day of his life at Fermilab.

One of the oddest features of special relativity is the inability to go faster than the speed of light. The most common explanation is that the mass of an object increases with speed, but this particular explanation simply isn’t true. Fermilab scientist Don Lincoln explains the truth behind this.
