The LHC is the world’s highest energy particle accelerator and scientists use it to record an unprecedented amount of data. This data is recorded in electronic format and it requires an enormous computational infrastructure to convert the raw data into conclusions about the fundamental rules that govern matter. In this video, Fermilab’s Dr. Don Lincoln gives us a sense of just how much data is involved and the incredible computer resources that makes it all possible.
The Muon g-2 experiment at Fermilab will use as its primary instrument a 52-foot-wide electromagnet that creates a precise magnetic field. In this video, Fermilab's Brendan Kiburg explains the lengthy process of finely "shimming" that magnetic field into shape. Learn more about the Muon g-2 experiment at http://muon-g-2.fnal.gov.

Particle physics experiments employ high energy particle accelerators to make their measurements. However there are many kinds of particle accelerators with many interesting techniques. One important dichotomy is whether one takes a particle beam and have it hit a stationary target of atoms, or whether one takes two counter rotating beams of particles and smashes them together head on. In this video, Fermilab’s Dr. Don Lincoln explains the pros and cons of these two powerful methods of exploring the rules of the universe.
The Axion Dark Matter Experiment (ADMX) is on the hunt for theoretical particles called axions, which may solve the dark matter mystery. ADMX, managed by Fermilab and housed at the University of Washington, is the first and only experiment of its type with the sensitivity to detect axion dark matter particles.

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.
For his 2018 Physics Slam presentation at Fermilab, Northwestern University scientist André de Gouvêa took on one of the most fascinating particles in physics: the neutrino. In 10 minutes, he explained—with the help of a few props—what neutrinos are and how physicists discovered that these particles can transform into one other, a phenomenon known as neutrino oscillation. At the end of the evening, the audience declared him to be the winner of the 2018 Physics Slam.

Anyone who has driven a car has an intuitive understanding of how velocities add. Two cars, heading towards one another head-on at a velocity, have a closing velocity of twice that velocity. It’s all very simple and yet at very high speeds this intuition is just wrong.
In this video, Fermilab’s Dr. Don Lincoln explains how to add velocities in a relativistic environment. It’s weird and wonderful and mind-bending.

The manner in which particle physicists investigate collisions in particle accelerators is a puzzling process. Using vaguely-defined “detectors,” scientists are able to somehow reconstruct the collisions and convert that information into physics measurements. In this video, Fermilab’s Dr. Don Lincoln sheds light on this mysterious technique. In a surprising analogy, he draws a parallel between experimental particle physics and bomb squad investigators and uses an explosive example to illustrate his points. Be sure to watch this video… it’s totally the bomb.
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.
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, Fermilab’s Dr. Don Lincoln describes a commonly claimed time dilation paradox and shows how to resolve it.

In the world of high energy physics there are several parameters that are important when one constructs a particle accelerator. Two crucial ones are the energy of the beam and the luminosity, which is another word for the number of particles in the beam. In this video, Fermilab’s Dr. Don Lincoln explains the differences and the pros and cons. He even works in an unexpected sporting event.
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.
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/ .

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.
Particle accelerator are scientific instruments that allow scientists to collide particles together at incredible energies to study the secrets of the universe. However, there are many manners in which particle accelerators can be constructed. In this video, Fermilab’s Dr. Don Lincoln explains the pros and cons of circular and linear accelerators.
This 4-minute animation shows how the international Deep Underground Neutrino Experiment will help scientists understand how the universe works. DUNE will use a huge particle detector a mile underground to embark on a mission with three major science goals: 1.) Study an intense, 1,300-kilometer-long neutrino beam to discover what happened after the big bang: Are neutrinos the reason the universe is made of matter? 2.) Use 70,000 tons of liquid argon to look for proton decay and move closer to realizing Einstein’s dream of a unified theory of matter and energy. 3.) Catch neutrinos from a supernova to watch the formation of neutron stars and black holes in real time. About 1,000 scientists from 160 institutions in 30 countries are working on the Deep Underground Neutrino Experiment, hosted at the Department of Energy’s Fermi National Accelerator Laboratory and South Dakota’s Sanford Underground Research Facility. DUNE collaborators come from institutions in Armenia, Brazil, Bulgaria, Canada, Chile, China, Colombia, Czech Republic, Finland, France, Greece, India, Iran, Italy, Japan, Madagascar, Mexico, Netherlands, Peru, Poland, Romania, Russia, South Korea, Spain, Sweden, Switzerland, Turkey, Ukraine, United Kingdom, and the United States of America.
One of the most outlandish ideas in modern physics is the multiverse - the idea that there exist multiple universes. Given that scientists tend to be fairly conservative and that this idea seems like a such a reach, it is natural to wonder why this idea is seriously discussed in leading scientific circles. In this video, Fermilab’s Dr. Don Lincoln explains how the existence of a multiverse is a possible answer to the question of why the universe seems so well tuned for human life.

Theoretical particle physics employs very difficult mathematics, so difficult in fact that it is impossible to solve the equations. In order to make progress, scientists employ a mathematical technique called perturbation theory. This method makes it possible to solve very difficult problems with very good precision. In this video, Fermilab’s Dr. Don Lincoln shows just how easy it is to understand this powerful technique.

The Big Bang is the name of the most respected theory of the creation of the universe. Basically, the theory says that the universe was once smaller and denser and has been expending for eons. One common misconception is that the Big Bang theory says something about the instant that set the expansion into motion, however this isn’t true. In this video, Fermilab’s Dr. Don Lincoln tells about the Big Bang theory and sketches some speculative ideas about what caused the universe to come into existence.

There are a few people in the history of physics who have made insights that have revolutionized our understanding of the interactions of math and physics and given us real insights into the meaning of our theories. In this video, Fermilab’s Dr. Don Lincoln tells us of the tale of Emmy Noether – one of the most significant geniuses of the last century.
