In physics, the twentieth century started with the twin
revolutions of relativity and quantum mechanics. Much of the second
half of the century was devoted to the construction of a
theoretical structure unifying these radical ideas,
confirmed...
A knot is simply a tangled loop in ordinary three-dimensional
space, such as often causes us frustration in everyday life. Knots
are also the subject of a rather rich mathematical theory. In the
last three decades, it has unexpectedly turned out...

Nima Arkani-Hamed, Professor, School of Natural Sciences
In this talk, Nima Arkani-Hamed,
Professor in the School of Natural Sciences, discusses the
direction of fundamental physics in coming years and decades,
including efforts to replace the concept of spacetime and
understand how the macroscopic...
Quantum theory radically transforms our fundamental
understanding of physical reality. It reveals that the world
contains a hidden richness of structure that we have barely begun
to control and exploit. In this lecture, Frank Wilczek indicates
the...
