In a long line of intellectual triumphs, Einstein’s theory of general relativity was his greatest and most imaginative.  It tells us that what we experience as gravity can be most accurately described as the bending of space itself.  This idea leads to consequences, including gravitational lensing, which is caused by light traveling in this curved space.  This is works in a way analogous to a lens (and hence the name).  In this video, Fermilab’s Dr. Don Lincoln explains a little general relativity, a little gravitational lensing, and tells us how this phenomenon allows us to map out the matter of the entire universe, including the otherwise-invisible dark matter.

Particle accelerators can fire beams of subatomic particles at near the speed of light. The accelerating force is generated using radio frequency technology and a whole lot of interesting features. In this video, Fermilab’s Dr. Don Lincoln explains how it all works.

Searching for the Higgs boson and other particles requires scientists to take into account statistics and probability in their analyses. Fermilab physicist Don Lincoln explains these concepts using simple dice.

A cancer diagnosis can be a devastating thing to hear, but new treatments are greatly improving a person’s chance of being cured. In this video, Fermilab’s Dr. Don Lincoln explains the physics of an exciting treatment option, called proton radiation therapy, which is far superior to traditional therapy, at least in some cases.

America’s leading particle physics laboratory is turning 50 years old this year. Fermilab’s Dr. Don Lincoln remembers the laboratory’s first half century and looks forward to the fascinating research topics that Fermilab’s scientific staff are looking at as they leap forward into the future.

One of the most difficult things in learning particle physics for the first time is to understand all of the various names. There are dozens and dozens and sometimes many names can apply to one particle or a single name can apply to many particles. It’s all very confusing. Luckily, Fermilab’s Dr. Don Lincoln made this video to help you sort it all out.

There are more than 30,000 particle accelerators in operation around the world. At Fermilab, scientists are collaborating with other laboratories and industry to optimize the manufacturing processes for a new type of powerful accelerator that uses superconducting niobium cavities. Experimenting with unique polishing materials, a Fermilab team has now developed an efficient and environmentally friendly way of creating cavities that can propel particles with more than 30 million volts per meter.

The Large Hadron Collider or LHC is the world’s biggest particle accelerator, but it can only get particles moving very quickly. To make measurements, scientists must employ particle detectors. There are four big detectors at the LHC: ALICE, ATLAS, CMS, and LHCb. In this video, Fermilab’s Dr. Don Lincoln introduces us to these detectors and gives us an idea of each one’s capabilities.

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 video, Fermilab’s Dr. Don Lincoln explains the real answer to this perplexing puzzle.

CORRECTION: There is a typo in the video. At 10:23, it says that the x position for observer C at event II is γL, but it should be 2γL. Dr. Lincoln is suitably embarrassed and apologetic.

The Department of Energy’s Fermi National Accelerator Laboratory and Northwestern University have established a new collaboration that enhances both institutions’ scientific research portfolios.
The Center for Applied Physics and Superconducting Technologies (CAPST) focuses on the science and applications of superconductivity, with expected advances in the fields of particle
physics, solid-state physics, materials science, medicine, energy and environmental sciences.
CAPST formally recognizes a broad intersection of scientific pursuits and complementary state-of-the-art facilities.
The center lays the groundwork for the cross-utilization of technical expertise, facilities, and equipment and establishes a partnership that will foster joint scientific research, mentorship, and new opportunities for researchers, graduate students, and postdoctoral
fellows.

On Monday, June 23, 2014 the MicroBooNE detector -- a 30-ton vessel that will be used to study ghostly particles called neutrinos -- was transported three miles across the Fermilab site and gently lowered into the laboratory's Liquid-Argon Test Facility. This video documents that move, some taken with time-lapse cameras, and shows the process of getting the MicroBooNE detector to its new home.

The Mandela effect is an idea that people move between parallel universes. Its name arises because 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. In this video, Fermilab’s Dr. Don Lincoln explains to his pet Albert why this is such a silly idea.

This 2-minute animation shows a virtual walk through the large caverns of the Long-Baseline Neutrino Facility, which will house the Deep Underground Neutrino Experiment. To create the caverns for the huge DUNE particle detectors, construction crews will excavate more than 800,000 tons of rock a mile underground at the Sanford Underground Research Facility in South Dakota. Scientists and dignitaries broke ground for this project on July 21, 2017. When construction is complete, DUNE scientists will send an intense neutrino beam through 1,300 kilometers of rock from the Department of Energy’s Fermilab to the DUNE particle detectors to understand the role that neutrinos – the most abundant matter particles in the universe – play in our cosmos. About 1,000 scientists from more than 160 institutions in 30 countries work on the Deep Underground Neutrino Experiment. More info is at http://dunescience.org

ProtoDUNE is a test bed for the Deep Underground Neutrino Experiment, an international physics project hosted at the Department of Energy's Fermilab. One of the ProtoDUNE detectors, which are being constructed at CERN, is a single-phase neutrino detector that uses liquid argon. It will require a number of anode plane arrays, special panels made of wire, to detect the signature of a neutrino interaction in the argon bath. This is a glimpse into the process of fabricating these planes, some of which are being created at the University of Wisconsin-Madison.

After a long water journey, a large crowd gathers to watch the muon-g-2 ring being placed onto the Emmert transporter for its journey to Fermilab.

In this public lecture, Fermilab physicist Dan Bauer explains what scientists know about dark matter, the mysterious, invisible stuff that accounts for most of the matter in the universe. After presenting evidence for the existence of dark matter, he describes some of the physics experiments that scientists build and operate to look for signals from dark matter particles. From going deep underground to operating equipment at temperatures close to absolute zero to operating the most powerful particle collider in the world, scientists are pushing technological boundaries in their quest to discover the building blocks of dark matter. This lecture was held at Fermilab in October 2018 as part of a worldwide series of events to celebrate Dark Matter Day.
