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.

On October 24, 2018, several math students took the Virginia Tech Math Contest. The Virginia Tech Contest is similar to the Putnam Exam, but perhaps somewhat easier; this year 94 schools from 29 states took part in the 40th contest and there were 792 participants. The maximum possible score was 70.
We were thrilled to discover two of our students ranked 2nd and 3rd nationwide!
Congratuations to Liwei Jiang (2nd) and Sivakorn Sanguanmoo (3rd).
Also notable, Xiaxin Li (21st) and Ruiting Tong (24th).
