The physics of musical saws, explored by Ig Nobel Prize winner Lakshminarayanan Mahadevan, was profiled in the New York Times: “Now L. Mahadevan, a professor of physics and applied mathematics at Harvard, along with two colleagues, Suraj Shankar and Petur Bryde, has studied the way the saw produces music and drawn some conclusions that help […]

Physics of the Running of the People from the Bulls
The running of the people who are running from the bulls at the Running of the Bulls in Pamplona, Spain, begs for some insights. Insights — insights about the running of those people from those bulls — course through the paragraphs of this newly published study: “Pedestrian Dynamics at the Running of the Bulls Evidence […]
“Why do I always spill my coffee?”
Oxford maths PhD student Sophie Abrahams explicates the Ig Nobel Prize-winning research on what happens when one walks backwards while (or whilst) holding a cup of coffee. The 2017 Ig Nobel Prize for fluid dynamics was awarded to Jiwon (Jessie) Han, for studying the dynamics of liquid-sloshing, to learn what happens when a person walks […]
Vibrating an Earthworm [Ig Informal Lecture]
Here is the Ig Informal Lecture by the winners of the 2020 Ig Nobel Physics Prize. The Ig Nobel Prizes honor achievements that make people LAUGH, then THINK. In the Ig Informal Lectures, some days after the ceremony, the new Ig Nobel Prize winners attempt to explain what they did, and why they did it. [In non-pandemic years, […]
The Reason You Will Spill Coffee, No Matter How Careful You Are
When a person walks while carrying a full cup (with no lid) of coffee, it is almost inevitable that some coffee will spill. Two Ig Nobel Prizes have honored research that analyzed why. Small Expedition Room produced this video news report [in Korean] about the phenomenon: Those Two Coffee-Spill Ig Nobel Prizes The 2012 Ig […]

How to Spill a Cup of Coffee
“How to Spill a Cup of Coffee” is a featured article in the special Coffee, and Tea issue (volume 26, number 4) of the Annals of Improbable Research. It looks at two studies—each of which led to an Ig Nobel Prize—about the physics of how and why anyone who walks with a full cup of […]
The physics of tossing fried rice
David Hu, who has two Ig Nobel physics prizes (the first for discovering nearly-universal urination duration in mammals, the second for studying why wombat poo is cubic-shaped) has a new study out with colleague Hungtang Ko, about the physics of tossing fried rice. The study is “The physics of tossing fried rice,” Hungtang Ko and […]
The Shoelace Catastrophe, examined today at Cornell
Cornell University is hosting a talk today about the how-do-shoelaces-come-untied problem— specifically about the math and physics of it: MAE Colloquium: “The Shoelace Catastrophe (or a Knotty Problem on a Shoestring“) Tuesday, September 3, 2019 at 4:00pm, B11 Kimball Hall ABSTRACT: The accidental untying of a shoelace while walking often occurs without warning. Modeling and […]
Wrinkled sheets, crumpled paper
New research about how paper crumples was done in the same chunk of Harvard that produced an Ig Nobel Prize-winning study about how sheets get wrinkled. It builds on—and adds new wrinkles to—that earlier research. Siobhan Roberts reports, in the New York Times, about the paper-crumpling study: This Is the Way the Paper Crumples In a […]
