The most famous equation in all of science is Einstein’s E = mc2, but it is also frequently horribly misunderstood and misused. In this video, Fermilab’s Dr. Don Lincoln explains the real truth about this equation and how people often use it wrong.

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 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.

Neutrinos are a mystery to physicists. They exist in three different flavors and mass states and may be able to give hints about the origins of the matter-dominated universe. A new long-baseline experiment led by Fermilab called NOvA may provide some answers. There is a live feed of the first detector block being moved at http://www.fnal.gov/pub/webcam....s/nova_webcam/index.

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 international Deep Underground Neutrino Experiment, hosted by Fermilab, will investigate the role neutrinos play in the universe. To test the technologies used by DUNE, scientists are building two large prototype detectors at CERN. Filled with 800 tons of liquid argon, the ProtoDUNE detectors are the largest particle detectors of their kind. The actual DUNE detector modules, which will be assembled 1.5 kilometers underground at the Sanford Underground Research Facility, will be 20 times bigger than these test beds. More than 1,000 scientists from research institutions in 32 countries are working on DUNE.

On Sept. 18, 2018, DUNE scientists announced the observation of the first particle tracks with the first of the two prototype detectors:

The ICARUS detector, one of the largest liquid-argon neutrino hunters in the world, makes the last leg of its international journey into its new home at the U.S. Department of Energy’s Fermi National Accelerator Laboratory. The detector was shipped to Fermilab in two modules in 2017. One year later, over a week in August 2018, it was carefully lowered into a specially built vessel that scientists will use to cool the detector in preparation for its new role: searching for a theoretical fourth type of neutrino.

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.

Scientists on Fermilab's Muon g-2 experiment are using a finely tuned clock to precisely measure how fast the muon — a heavy cousin of the electron — precesses, or wobbles, in the presence of a magnetic field.

To remove subconscious bias from the experiment's measurements, in March 2018, two Fermilab scientists outside the Muon g-2 collaboration set the clock to a certain frequency. For the period that Muon g-2 is taking data, only they will know that setting. This bias-removal technique is called clock blinding.

The PIP-II project http://pip2.fnal.gov is an essential upgrade of Fermilab’s particle accelerator complex and includes the construction of a 215-meter-long linear particle accelerator. It is the first U.S. particle accelerator project with significant contributions from international partners. Research institutions in France, India, Italy and the UK will build major components of the new particle accelerator.

PIP-II will become the new heart of the Fermilab accelerator complex. Its high-intensity proton beams will provide a flexible platform for the long-term future of the Fermilab accelerator complex and the U.S. accelerator-based particle physics program. The upgrade will enable Fermilab’s accelerator complex to generate an unprecedented stream of neutrinos—subtle, subatomic particles that could hold the key to understanding the universe’s evolution—by creating the world’s most intense high-energy neutrino beams. This capability positions Fermilab to be the world leader in accelerator-based neutrino research. It enables the scientific program for the international, Fermilab-hosted Deep Underground Neutrino Experiment (DUNE) and Long-Baseline Neutrino Facility (LBNF). http://www.fnal.gov/dune

The use of superconducting radio frequency (SRF) technology is a driving force in the development of particle accelerators. Scientists from around the globe are working together to develop the newest materials and techniques to improve the quality and efficiency of the SRF cavities that are essential for this technology.

If there’s one thing that we think we understand, it’s matter.  After all, matter makes up everything around us; it even makes up you.  However, all is not as it seems.  Over the last century, scientists have learned about the building blocks of matter, starting with atoms.  It turns out that matter is very different than you think. In this video, Fermilab’s Dr. Don Lincoln will give you an entirely new way to think about the world around us.  You will never think of the universe in the same way again.

The Large Hadron Collider (or LHC) is the world’s most powerful particle accelerator.  In 2012, scientists used data taken by it to discover the Higgs boson, before pausing operations for upgrades and improvements.  In the spring of 2015, the LHC will return to operations with 163% the energy it had before and with three times as many collisions per second.  It’s essentially a new and improved version of itself.  In this video, Fermilab’s Dr. Don Lincoln explains both some of the absolutely amazing scientific and engineering properties of this modern scientific wonder.

The Twin Paradox is the most famous of all of the seeming-inconsistencies of special relativity. In this video, Fermilab’s Dr. Don Lincoln explains it without using mathematics. This is a companion video for his earlier one in which the same question was handled mathematically.

Particle accelerators are one of the most powerful ways to study the fundamental laws that govern the universe. However, there are many design considerations that go into selecting and building a particular accelerator. In this video, Fermilab’s Dr. Don Lincoln explains the pros and cons of building an accelerator that collides pairs of protons to one that collides electrons.

Radiation is all around us, ranging from the non-dangerous to the lethal. In this video, Fermilab’s Dr. Don Lincoln talks about the radiation and gives you the real deal on whether it is dangerous or not. (Spoiler alert: Sometimes!)

Fermilab is one of the world’s finest laboratories dedicate to studying fundamental questions about nature. In this video, Fermilab’s own Dr. Don Lincoln talks about some of Fermilab’s leading research efforts that will lead the field for the next decade or two.
