Q&A

For decades, physicists have struggled to develop a quantum theory of gravity. But what if gravity — and space-time — are fundamentally classical?

The marine geochemist Chris German brings decades of experience studying seafloor hydrothermal vents to NASA’s preparations for visits to other ocean worlds in our solar system.

Renate Loll has helped pioneer a radically new approach to quantum gravity. She assumes that the fabric of space-time is a blend of all possible fabrics, and she has developed the computational tools needed to calculate the far-reaching implications of that assumption.

Minhyong Kim is leading a new initiative called Mathematics for Humanity that encourages mathematicians to apply their skills to solving social problems.

Cynthia Rudin wants machine learning models, responsible for increasingly important decisions, to show their work.

On Mount Everest and in the Peruvian Andes, Tracie Seimon uses DNA to study how species and ecosystems respond to climate change, pathogens and other influences.

The prize-winning geometer feels most fulfilled when exploring the fertile ground where constraint meets creation.

Arvind Narayanan uses quantitative methods to expose and correct the misuse of quantitative methods.

Lek-Heng Lim uses tools from algebra, geometry and topology to answer questions in machine learning.
