About me

Hello! I’m Kazi Abu Rousan, a recent graduate from the Indian Association for The Cultivation of Science, where I earned my master's degree in Physics with a specialization in Cosmology. In addition to my academic background, I have a passion for teaching and currently instruct students in Mathematics and Physics for Olympiad preparation at Cheenta Ganit Kendra. I am also a member of Institute of Physics.

Ohh and here is my catto! Mr. Gino!

Some of my Works

Some of the things written by me,

• Time Crystal as a consequence of NonCommutative Quantum Mechanics for 2D Harmonic Oscillator

This was done in the 2023 summer research project under the guidence of Prof. Archan S Majumdar under S. N. Bose National Centre for Basic Sciences.

• Basic Recombination and Formation of Neutral Hydrogen in Early Universe

In this article I have discussed the mechanism of Recombination in the early universe and have discribed Peeble's Equation.

• Extension of Gauss circle problem: Lattices for a Triangular grid and discovery of a new formula of \(\pi\)

Here I have tried to extend the Gauss's Circle Problem for a triangular grid and also found a new infinite series for \(\pi\).

• Diffraction patterns by different orientation of rectangular Apertures: Intuitive understanding of Optical Transformations

This article is based on a problem which came in tifr exam. Here, I have discussed how diffraction patterns can change depending upon different configuration of apertures and simulated the things using python.

• Method of Images and It's Relation to Optical Images

Here I have tried to show how Optical Lense formulas are similar to that of electrostatic method of images.

• Introduction to Anyons and Generalized Distribution Function

This is my BSc. project, here I have tried to find a generalized distribution function which anyons follow. We can get Bosonic and Fermionic distribution function from that function as a special case.

• Cosmic.jl: A simple package for study of Cosmology

This is a julia package I am developing in my free time for calculating some basic things of Cosmology. The goal of this package is to compute Cosmological Perturbations. Although for now, it can only do very basic things and is far from it's real goal.

• I also loves to make animation using manim– a python library build by Grant (3blue1brown) to make animation videos on different topics of maths and physics. Here is the playlist.

Some of my blogs on medium are,

• What is Fourier Series? and It's Beauty. You can also watch a video on this.

• Trapezoidal Rule: A Method of Numerical Integration

Some extra Mentorship

• I have been a mentor for a Summer School of Astrophysics in 2023. For more visit their website here. To access notes and assignment visit here (The ones on matplotlib and numpy, Scipy and Astropy are made by me).

• I am teaching the python part of a course Approaching Computational Thinking with R + Python organised by Cosmic Charade.

• I am writing a book on Number Theory. You can check the draft.

• Recently, I have started doing digital art. Here are some of them here.
