The Mandela effect is an idea that people move between parallel universes. Its name arises from the fact that some people have firm memories of Nelson Mandela dying in prison when, in fact, he was released and went on to be President of South Africa. Don Lincoln explains why the parallel universe explanation is a silly one.

The hunt for the top quark at Fermilab was heating up in 1994 when scientist Mike Albrow and his colleagues on the CDF experiment felt they were close to cornering the last, undiscovered member of the quark family. Albrow tells the story leading to the discovery of the particle by CDF and DZero.

A renowned physicist and recipient of numerous science awards, including the Nobel Prize, famed former Fermilab Director Leon Lederman was everyman to the kids he met. Fermilab’s Dee Hahn recounts how Lederman entertained the children at the Fermilab daycare center.

In this 10-minute video, scientist Don Lincoln talks about the gamut of radiation levels, from safe to harmful (and cinematically enhanced).

Scientists Rocky Kolb and Mike Turner recount the time they first proposed that Fermilab – dedicated to the study of the universe’s smallest constituents — expand its program to include the stars, galaxies and the cosmos.

Fermilab’s website was born in June 1992, thanks in part to Tim Berners-Lee, who invented the World Wide Web in 1989. Fermilab’s Ruth Pordes tells the origin story.

This 4-minute animation shows how the international Deep Underground Neutrino Experiment will help scientists understand how the universe works.

Radiation is one of those words that many people misunderstand. In this video, Fermilab’s Dr. Don Lincoln explains the known kinds of nuclear radiation and their different properties.

Adrienne Kolb, former Fermilab archivist and historian, came to live at the laboratory in 1983 with her husband, their three children and their dog. On-site country living included frequent science conferences, regular encounters with wildlife and lively, neighborly gatherings.
