I will review the phenomenological successes of MOND on the scale of galaxies. I will discuss its failure on cosmological scales. These large scale problems have been understood for decades, are very robust and their origin can be easily understood...

The last years have seen remarkable progress in understanding the scattering amplitudes of massless particles in arbitrary dimension. They exhibit structures and a simplicity completely obscured by the Feynman diagram approach, and can be shown to...

I will review the lightcone bootstrap and explain how it canbe used to describe analytically some new numerical results for the 3dIsing CFT.

I will explain in examples how to incroporate the dependence on spin structure in fermionic lattice models. In two dimensions, I show to construct a spin-TQFT out of a superalgebra. In three dimensions, it turns out that fermionic lattice models are...
