Particle Physics

"Edward Witten has spent almost 50 years at the forefront of theoretical and mathematical physics. Here he describes how the LHC and other recent results have impacted his view on nature, and asks whether naturalness is still a useful guide for the field."

When particle physicists try to model experiments, they confront an impossible calculation — an infinitely long equation that lies beyond the reach of modern mathematics. But three recent papers from a group of physicists led by Sebastian Mizera...

The 2017 Prospects in Theoretical Physics program will celebrate its sixteenth year by convening more than 130 graduate students and postdoctoral scholars from around the world at the Institute for Advanced Study from July 17 to 28 to explore...

“What is space and time really? Why is the universe really big?” Professor Nima Arkani-Hamed asks. “And on top of that, we don’t understand why there are big things in it.”

Part of a family that zigzagged the globe in pursuit, and defense, of science...

New math shows how, contrary to conventional scientific wisdom, conscious beings and other macroscopic entities might have greater influence over the future than does the sum of their microscopic components.

In a recent essay, Erik Hoel, Visitor in...

The New York Times's Dennis Overbye writes about the origins and purpose of Sesame (Synchrotron-light for Experimental Science and Applications in the Middle East), a project spearheaded by former Member Eliezer Rabinovici, a theoretical physicist...

How does science work? . . . The scientific method—famously objective, logical and eminently reliable; and the fruits of its success, both pure and applied, are the single most obvious factor in distinguishing the varying levels of progress between...

In this month's "Quantized Column," Quanta Magazine's series in which top researchers explore the process of discovery, Frank Wilczek, Professor (1989–2000) and Member (1977–78) in the School of Natural Sciences and Nobel Laureate in Physics (2004)...

An unexpected connection has emerged between the results of physics experiments and an important, seemingly unrelated set of numbers in pure mathematics.

“If it were true that there were a group acting on the numbers coming from physics, that means...

Physicists, including Nima-Arkani Hamed, Professor in the School of Natural Sciences, are confronting their “nightmare scenario.”
