The Universe is always surprising us with how little we know about... the Universe. It's continuously presenting us with stuff we never imagined, or even thought possible. The search for extrasolar planets is a great example. Since we started, astronomers have turned up over a thousand

Vera Serganova: Capelli eigenvalue problem for Lie superalgebras and supersymetric polynominals
Abstract: We study invariant differential operators on representations of supergroups associated with simple Jordan superalgebras, in the classical case this problem goes back to Kostant. Eigenvalues of Capelli differential operators give interesting families of polynomials such as super J

If you rotate a bowling ball, it looks the same even though it's been "transformed". We say that the bowling ball exhibits "rotational symmetry". The particles making up the universe exhibit related kinds of symmetries, in which the particles are transformed but the equations describing th

Axel de Goursac: Noncommutative Supergeometry and Quantum Field Theory
In this talk, we present the philosophy and the basic concepts of Noncommutative Supergeometry, i.e. Hilbert superspaces, C*-superalgebras and quantum supergroups. Then, we give examples of these structures coming from deformation quantization and we expose an application to renormalizable

AWESOME SUPERCONDUCTOR LEVITATION!!!
A quantum levitator it's a circular track of magnets above which a razor-thin disc magically levitates, seeming to defy the laws of physics. The key to the levitator is the disc, which is made of superconducting material sandwiched between layers of gold and sapphire crystal. A piece of fo
