How to Integrate over Grassmann Numbers in Quantum Field Theory? (Berezin Integral)
In this video, we will show you how to do integrals with Grassmann numbers. Grassmann numbers are an important concept in quantum field theory, where we use them to describe fermions. They are named after the German mathematician Hermann Grassmann. The special thing about Grassmann numbers

Have you ever had a ketone and wished you had an amide instead? Not to worry! The Beckmann rearrangement is the solution to your problems. Check out this nifty reaction where we get an oxime and then get an alkyl group to migrate. We can even create cyclic amides which are called lactams.

The scaling limit of any 2D Ising model with ferromagnetic short range interactions at the critical point is expected to be a Conformal Field Theory with c=1/2, one instance of which is the theory of free Majorana fermions. This expectation comes with extremely detailed predictions on crit
