November 08, 2021

This week, I will be hosting a session on Geometry at the IIIT-H programming club, where I plan to discuss a few techniques and problems.

At first sight, computational geometry might seem very hard and intimidating. But once you familiarize yourself with some basic tools and tricks, you’ll become a geometry expert! Let’s break the myth “geometry is hard” together!

Regular tilings of the 2D plane

June 03, 2021

I recently came across Euclidean tilings by convex regular polygons, which is super interesting. The problem is to fill the entire (infinite) 2D plane with non-overlapping regular polygons. The simplest case is to use a single regular polygon of fixed size - called Regular Tilings.

What is a variety?

Of course, I am not talking about the English word “variety” here, which everyone knows the meaning. I am referring to algebraic varieties. These are the primary objects one studies in algebraic geometry. I am no expert on the subject, but I have a little understanding of the concept. I would like to share my thoughts and insights by showing some elementary and common examples everyone would have seen sometime or the other - completely unaware that they are varieties in disguise!
