Applying physics to mathematics

leave a comment »

by Tadashi Tokieda

abstract : Humans tend to be better at physics than at mathematics. When an apple falls from a tree, there are more people who can catch it—we know physically how the apple moves—than people who can compute its trajectory from a differential equation. Applying physical ideas to discover and establish mathematical results is therefore natural, even if it has seldom been tried in the history of science. (The exceptions include Archimedes, some old Russian sources, a recent book by Mark Levi, as well as my articles and lectures.) This TMC Distinguished Lecture presents a diversity of examples, and tries to make them easy for imaginative beginners and difficult for seasoned researchers.

What does the Muon g-2 experiment tell us?

leave a comment »

The Muon g-2 experiment announced one of the most tantalizing physics measurements in over a decade. It is possible that the measurement tells us that our theoretical calculation is missing some new physical phenomena. It is also possible that a new theoretical prediction points to the possibility that measurement and prediction basically agree. In this exciting video, Fermilab’s Dr. Don Lincoln gives you an insider’s perspective.

COVID vaccines and blood clots: five key questions

leave a comment »

It has been a difficult week for two COVID-19 vaccines. On 13 April, US regulators urged health-care providers to temporarily stop using a vaccine made by Johnson & Johnson (J&J) of New Brunswick, New Jersey, because of six suspected cases of unusual blood clotting among nearly seven million vaccine recipients. The move came after European regulators expressed concerns about a possible link between rare blood clots and the Oxford–AstraZeneca vaccine, developed in the United Kingdom by AstraZeneca in Cambridge and the University of Oxford ….

What Can Wobbling Muons Tell Us About the Particles in our Universe?

leave a comment »

Fermilab’s Dr. Adam Lyon breaks down the first results from the Muon g-2 experiment in this special public lecture, part of the Fermilab Arts and Lecture Series.

On April 7, 2021, the Muon g-2 experiment hosted at the U.S. Department of Energy’s Fermi National Accelerator Laboratory released its long-awaited first results. The results show fundamental particles called muons behaving in a way that is not predicted by our best theoretical model of the subatomic world, the Standard Model of particle physics. The strong evidence that muons deviate from the Standard Model calculation might hint at exciting new physics. Muons act as a window into the subatomic world and could be interacting with yet undiscovered particles or forces.

In the experiment, muons (heavy cousins of electrons) race around the 150-foot circumference magnetic racetrack, wobbling as they go, like tops slowly spinning on their axes. Quantum mechanics allows for “virtual” subatomic particles to ever so briefly come in and out of existence and affect the wobble of the muons. The Fermilab experiment measures this wobbling with greater precision than ever before.

Adam Lyon is a senior scientist and associate division head at Fermilab. He specializes in computing for experimental particle physics – both traditional classical computing and, more recently, quantum computing. He joined the Fermilab Muon g-2 experiment at its founding in 2011.
