Quantum Theory

"Natalie Paquette spends her time thinking about how to grow an extra dimension. Start with little circles, scattered across every point in space and time—a curlicue dimension, looped back onto itself. Then shrink those circles down, smaller and smaller, tightening the loop, until a curious transformation occurs: the dimension stops seeming tiny and instead becomes enormous, like when you realize something that looks small and nearby is actually huge and distant."

"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."

Professor Nathan Seiberg sat down with Sandhya Ramesh at an event organised by the International Centre for Theoretical Sciences for an interview for the Wire to discuss string theory, experimental evidence, quantum field theory, and more.
