Saverio Spagnolie and Arthur Evans of UW–Madison, University of Michigan physicist Christopher Miles and mathematician Michael Shelley of the Flatiron Institute and New York University found that when the particles are confined to a thin sheet and allowed to expand into an empty fluid, the collective motion can be described by equations already used in entirely different classical problems in fluid mechanics. The group published its findings recently in the journal Physical Review Letters.
Two of our talented Math graduate students have been honored with campus-wide teaching awards.
Soumya Sankar has won the Exceptional Service Award and Di Fang has won the Capstone Ph.D. Teaching Award.
Of over 2000 teaching assistants on campus, these two were honored among a class of 13 others for their contributions to the classroom, lab, and field teaching contributions.
We are thrilled at the recognition by campus of our promising graduate students and their outstanding teaching!
Two of the four articles published this month in the Bulletin of the American Mathematics Society have UW connections. Daniel Erman and former faculty, Steven Sam, have an article titled "Cubics in 10 variables vs. cubics in 1000 variables: Uniformity phenomena for bounded degree polynomials". Jordan Ellenberg has been involved in work related to what Joshua Grochow published "New applications of the polynomial method: The cap set conjecture and beyond".
Hundreds of meters deep in the dark of the ocean, a shark glides toward what seems like a meal. It’s kind of ugly, eel-like and not particularly meaty, but still probably food. So the shark strikes.
This is where the interaction of biology and physics gets mysterious — just as the shark finds its dinner interrupted by a cloud of protective slime that appeared out of nowhere around an otherwise placid hagfish.
Jean-Luc Thiffeault, a University of Wisconsin–Madison math professor, and collaborators Randy Ewoldt and Gaurav Chaudhary of the University of Illinois have modeled the hagfish’s gag-inducing defense mechanism mathematically, publishing their work in the Journal of the Royal Society Interface.
