Dirichlet Eta Function - Integral Representation
Today, we use an integral to derive one of the integral representations for the Dirichlet eta function. This representation is very similar to the Riemann zeta function, which explains why their respective infinite series definition is quite similar (with the eta function being an alte rna

Basic Dirac Notation For Intellectuals
Let's go over some basic dirac notation for quantum mechanics. I go over how to write a vector as a linear combination of basis vectors, and how to find the components of a vector in dirac notation. I also go over the completeness relation as a sum of outer products. For information on my

(ML 7.8) Dirichlet-Categorical model (part 2)
The Dirichlet distribution is a conjugate prior for the Categorical distribution (i.e. a PMF a finite set). We derive the posterior distribution and the (posterior) predictive distribution under this model.

Quantum Field Theory 1a - Creation and Destruction I
The theory of quantum mechanics we developed in the previous series has some loose ends. Notably: 1) We talk about photons being emitted (created) and absorbed (destroyed) but we haven't given a rigorous description of this process. 2) The Dirac equation implies the presence of a "Dirac se
