A key outstanding question in our understanding of star formation is
 whether magnetic fields provide support against the gravitational
 collapse of their parent molecular clouds and cores. Direct

Condensed Matter Seminar: "The life of a vortex knot: Linking coiling and twisting across scales"

William Irvine, University of Chicago
- DRL A4

Can you take a vortex loop - akin to a smoke ring in air - and tie it into a knot or a link? The possibility of such knottiness in a fluid has fascinated physicists and mathematicians ever since Kelvin¹s 'vortex…

The Henry Primakoff Lecture: Was Einstein Right? A Centennial Assessment

Clifford Will (University of Florida)
- DRL A8

A century after Einstein's formulation of general relativity, a remarkably diverse set of precision experiments has established it as the ``standard model'' for gravitational physics.   Yet it might not be the…



GR Math Seminar: "The graded Lie algebra of general relativity "

Michael Reiterer (IAS and Penn)

Several problems can be written as [x,x]=0 where the unknown x
is an element of degree one in a graded Lie algebra. I show that general
relativity (the Einstein vacuum equations) can also be put in…
