The twin paradox is the most famous of all of the seeming inconsistencies of special relativity. In this video, Don Lincoln explains it without using mathematics.

The 6,800-acre Fermilab site is home to a chain of particle accelerators that provide particle beams to numerous experiments and R&D programs. This 2-minute animation explains how the proton source provides the particles that get accelerated and travel through the accelerator complex at close to the speed of light. Scientists use these beams to generate protons, neutrons, muons, pions and neutrinos for various research areas across the Fermilab site. More than 4,000 scientists from over 50 countries use Fermilab and its particle accelerators, detectors and computers for their research.

As a child, Kirsty Duffy learned about the smallest building blocks that make up the world and was inspired to pursue physics through high school and college. She talks not only about self-doubt in one’s abilities, but the thrill of making a discovery and being the one to share it with the world.

There is no more famous conundrum in special relativity than the Twin Paradox. One twin travels at great distance at the speed of light and returns, much younger than the other twin. Yet who is moving and who isn’t? It is commonly claimed that acceleration is crucial to explaining this paradox, yet it turns out to not be the important point. In this 13-minute video, Don Lincoln explains the real answer to this perplexing puzzle.

Fermilab recently hosted more than 300 middle school students from 13 schools for a special showing of Hidden Figures and a panel discussion with four Fermilab scientists, including Karl Warburton. This video was played as part of the panel introductions. The goal of the program was to show fifth- to eighth-grade students that entering a STEM field was possible for them – no matter their background. You can read more about the event here: http://news.fnal.gov/2018/02/fermilab… Karl Warburton discusses how every physicist always adds something to the field since every individual approaches the study in a new way. A scientist on the Deep Underground Neutrino Experiment, Warburton draws new information from pictures of simulated events, and each piece, collaboratively sewn together, contributes to our understanding of the universe.

Einstein’s special theory of relativity is notorious for being easy to misuse, with the result that sometimes result in claims of paradoxes. When one digs more carefully into the theory, you find that no such paradoxes actually exist. In this video, Don Lincoln describes a commonly claimed time dilation paradox and shows how to resolve it.

In this 3-minute video, Maurice Ball talks about challenges he faced in his college courses. Overcoming them, he found himself taking on different, surprising and exciting challenges as a Fermilab engineer.

Welcome to the first in a series by Don Lincoln on relativity. In this 12-minute video, he lays out what relativity is all about — not slow-moving clocks and shrinking objects, but instead on … well, watch and see.

The Linac Coherent Light Source at the Department of Energy’s SLAC National Laboratory is an X-ray laser that allows scientists to take snapshots of atoms and molecules in motion, revealing fundamental processes in materials, technology and living things. Its strobe-like pulses are just a few millionths of a second long, and a billion times brighter than previous X-ray sources. Fermilab is providing SLAC with 22 cryomodules for the LCLS-II upgrade, which will take X-ray science to the next level, opening the door to a whole new range of studies of the ultrafast and ultrasmall.

One of the ProtoDUNE experiment’s detectors is a single-phase neutrino detector. It will require a number of anode planes to detect the signature of a neutrino interaction in a bath of liquid argon. The University of Wisconsin is fabricating some of these anode planes. This is a glimpse at the process.
