John Urschel: NFL Athlete, Mathematician

Baltimore Ravens offensive lineman John Urschel will begin a PhD in mathematics at the Massachusetts Institute of Technology this year. He graduated from Penn State with a 4.0 GPA. His PhD studies will focus on spectral graph theory, numerical linear algebra, and machine learning. In a previous interview, Urschel told a reporter that he spends time on road trips reading math books and research papers. Read more about this incredible athlete-mathematician here!

Chocolate Fountains

Why does the falling curtain of chocolate on a chocolate fountain pull inwards rather than straight downwards?

One mathematics student figured out that chocolate fountains follow the same pattern as ‘water bells, ‘ which fall inwards because of surface tension. You can make your own water bell at home by ¬†putting a pen vertically under a tap with a coin flat on top, and you’ll see a bell-shaped fountain of water.

Crime Rates

“Crime in Los Angeles dropped dramatically when the Los Angeles Police Department deployed officers based on crime predictions made by a mathematical model, a team of scholars and police department colleagues reports today. The mathematical model would be effective in cities worldwide, the researchers said.” Read more here!
