## Student work earns national praise in data science competition

A computer model to help clinicians predict Parkinson’s disease progression has landed two Rochester undergraduates and their faculty mentor a top honor from the Michael J. Fox Foundation.

## Mathematician and longtime University faculty member Ralph Raimi dies at 92

After being named professor emeritus in 1995, Raimi became active in efforts to reform K–12 math education. Considered one of the top education experts in the country, he was a mathematics curriculum consultant to states across the country.

## WeBWorK an award-winning way of learning from homework

Twenty years ago, the idea of students doing homework online and receiving immediate feedback was a game-changer. Today, more than 700 colleges and high schools and using the WeBWorK system developed by Rochester math professors Arnold Pizer and Michael Gage.

## Scientists in Spain create first ever ‘magnetic wormhole’ in lab

The team was inspired by the theoretical work of Allan Greenleaf, a professor of mathematics at the University of Rochester in New York.

## Classic formula for ‘pi’ connects pure math and quantum mechanics like a ‘magic trick’

Oddly enough, but not that surprising considering the prevalence of pi in nature, researchers from the University of Rochester reached the same formula while they were computing the quantum mechanical energy stats of hydrogen.

## Revealing the hidden connection between pi and Bohr’s hydrogen model

[Carl] Hagen turned to his colleague, mathematics professor Tamar Friedmann, who found that they could derive Wallis’s infinite product from the ratio of the approximate energies to the exact energies.

## Scientists look into hydrogen atom, find old recipe for pi

A pair of quantum scientists calculating the energy levels of a hydrogen atom at the University of Rochester have discovered a 360-year-old formula for pi in their equations.

## Everything you ever wanted to know about pi, part 2: how pi connects to quantum mechanics

I had planned for part 2 of this series about p to be about the classical area formula for the circle, but then something new came up. Well, by new I mean a new proof of something old, and it’s a surprising proof using physics.

## Discovery of classic pi formula a ‘cunning piece of magic’

When most people think about pi, they associate the mathematical constant with arcs and circles. Mathematicians, however, are accustomed to seeing it in a variety of fields. But two University physicists were still surprised to find it lurking in a quantum mechanics formula for the energy states of the hydrogen atom.

## Allan Greenleaf named a fellow of American Mathematical Society

The AMS awards fellowships to recognize “members who have made outstanding contributions to the creation, exposition, advancement, communication, and utilization of mathematics.” Greenleaf is being singled out for his “contributions to inverse problems with applications to cloaking, as well as for service to AMS.”
