Thinking About Spacetime Symmetries in Field Theory
In which I try to rephrase the physics understanding of spacetime symmetries in the language of principal bundles.

Fiorentino Pictureshow
I visited the Galileo Galilei Institute in Florence for a couple of weeks in April and May. Here are some pictures from the trip.

A Cursed Space in the Wild
Recently, I had the misfortune of coming across the Sierpiński 2-point space in the wild. And while I’m sure that I must have seen it within minutes of learning the definition of a topological space, seeing it arise naturally in a linear algebra problem (of all places!) was horrifying.

An Outline for Witten's Analytic Continuation of Chern–Simons Theory
I hate reading long PDFs that do not have an outline attached. So, I spent one afternoon making an outline for arXiv:1001.2933, when I should have been reading it.

How to Make a NiSERCast
It has been a year since the last episode of NiSERCast, and it has been more than two years since the idea of a science communication podcast led by NISER students was initially conceived. Partly for archival reasons and partly for self-indulgent reasons, here are some reflections from my involvement in the project.

How to (Not) Write a Computational Physics Library
An introduction to my misguided attempt at writing a computational physics library from *scratch*. In this post I try to convince myself that using ANSI C for this project is not a mistake.

Quantum Isothermal Processes are Not Isoenergetic
I define what it means for a quantum system to undergo an isothermal process, and we see that unlike what happens for a classical ideal gas, the internal energy of the system can change in such a process.

Origin of Angular Momentum Quantization in Bohr's Model of Hydrogen Atom
To me, the quantization of angular momentum in terms of ħ has always felt like a very ad hoc assumption. In this post I start with the information available to Bohr at the time and derive the famous quantization rule.

Electromagnetic Fields and Arbitrary Lorentz Transformations
This post goes over the algebra involved in deriving the expressions of electric and magnetic fields under the most general Lorentz transformation. I could not find this anywhere else on the internet.
