While there are many challenges facing modern particle physics, perhaps the ultimate one (and certainly among the most difficult) is to describe the nature of gravity in the quantum realm.  Despite a century of effort, scientists have had only the most cursory of success.  In this video, Fermilab’s Dr. Don Lincoln talks about the idea of quantum gravity and sketches out the need for this difficult advance.

The strongest force in the universe is the strong nuclear force and it governs the behavior of quarks and gluons inside protons and neutrons.  The name of the theory that governs this force is quantum chromodynamics, or QCD.  In this video, Fermilab’s Dr. Don Lincoln explains the intricacies of this dominant component of the Standard Model.

The Higgs boson was discovered in July of 2012 and is generally understood to be the origin of mass. While those statements are true, they are incomplete. It turns out that the Higgs boson is responsible for only about 2% of the mass of ordinary matter. In this dramatic new video, Fermilab’s Dr. Don Lincoln tells us the rest of the story.

The Higgs boson burst into the public arena on July 4, 2012, when scientists working at the CERN laboratory announced the particle’s discovery. However the initial discovery was a bit tentative, with the need to verify that the discovered particle was, indeed, the Higgs boson. In this video, Fermilab’s Dr. Don Lincoln looks at the data from the perspective of 2016 and shows that more recent analyses further supports the idea that the Higgs boson is what was discovered.

The data presented in this video can be seen in a technical form in this paper: http://cds.cern.ch/record/2158....863/files/jhep-08-04 Figure 19 is a more accurate version.

The Standard Model of particle physics is composed of several theories that are added together.  The most precise component theory is the theory of quantum electrodynamics or QED.  In this video, Fermilab’s Dr. Don Lincoln explains how theoretical QED calculations can be done.  This video links to other videos, giving the viewer a deep understanding of the process.

The idea of electric charges and electricity in general is a familiar one to the science savvy viewer. However, electromagnetism is but one of the four fundamental forces and not the strongest one. The strongest of the fundamental forces is called the strong nuclear force and it has its own associated charge. Physicists call this charge “color” in analogy with the primary colors, although there is no real connection with actual color. In this video, Fermilab’s Dr. Don Lincoln explains why it is that we live in a colorful world.

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.

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. More information is at http://www.fnal.gov/pub/science/ .

Relativity has many mind-bending consequences, but one of the weirdest is the idea that objects in motion get shorter. Bizarre or not, Fermilab’s Dr. Don Lincoln explains just how it works. You’ll be a believer.

Most particle physics research is publicly funded, so it is fair that society asks if this is a good use of taxpayers’ money. In this video, Fermilab’s Dr. Don Lincoln explains how this research attempts to answer questions that have bothered humanity since time immemorial. And, for those with a more practical bent, he explains how this research is an excellent investment with a high rate of return for society.

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 one story about the lead-up to the discovery of the particle by CDF and DZero.

In this 45-minute presentation Alex Himmel, Wilson Fellow at Fermi National Accelerator Laboratory, explains how neutrinos might provide the answers to many questions that scientists have about the universe. The neutrino is a type of subatomic particle. They are produced in copious quantities by celestial objects -- trillions of neutrinos from the sun will pass through your body while you read this sentence -- but they interact so rarely with other particles that only a handful will strike an atom in your body during your entire life. Yet these benign little particles can tell us about some of the most energetic processes in the universe. In order to detect these elusive particles, scientists build enormous particle detectors deep underground, using tanks full of liquid argon in an old gold mine as well as a cubic kilometer of Antarctic ice. In this talk Himmel works his way from the sun to galactic supernovae to the possible extragalactic sources of the highest-energy neutrinos ever observed. Himmel also answers audience questions from members of the Naperville Astronomical Association.

Scientists, engineers and technicians are preparing for the assembly of a 15,000-ton neutrino detector in Ash River, Minnesota.

They gather at Fermilab to test a very large, critical piece of equipment that will be used in the assembly of this detector

This clip shows the "Miss Katie" pushing the muon g-2 ring upstream on the Illinois River, and passing through the Peoria Lock and Dam as it travels toward Lemont, where it will be unloaded onto the special Emmert transporter and driven to Fermilab.

Scientist Craig Moore talks about a small fix in an accelerator that paid big dividends for the Tevatron program in the 1990s.

Fermilab's fourth annual Physics Slam, held on Nov. 20, 2015, featured five physicists vying to explain their area of study in the most entertaining way possible. Contestants included 9:28 Brian Ingram, 20:10 Brad Benson, 32:52 Cindy Joe, 43:50 Steve Nahn and 54:39 Chris Marshall, and the event was hosted by Chris Miller of the College of DuPage.
