Carina Curto, a mathematician at Pennsylvania State University, explains how her background in theoretical physics helps her tackle daunting problems in theoretical neuroscience.

Lisa Manning, a physicist at Syracuse University, describes how the physics of glassy materials helps to explain how some organs assume their correct shape during embryonic development.

Michela Massimi argues that the philosophy of science doesn’t have to be useful to scientists for it to be useful to humanity.

Donald Richards discusses the statistical rule-of-thumb he wishes everyone knew.

Günter Ziegler describes one of the most famous and beautiful proofs in Proofs From THE BOOK, a book he co-authored with Martin Aigner.

Barbara Engelhardt, a computer scientist at Princeton University, explains why traditional machine-learning techniques have often fallen short for genomic analysis, and how researchers are overcoming that challenge.

Goldman explains how “smarticles” work together to demonstrate collective behavior.

Kalai argues that limiting the noise in a quantum computer will also limit the computational power of the system.
