Orbital Maneuvers and the Oberth Effect

Posted on Tue 05 July 2022 in General • Tagged with Writing

Once a rocket is in orbit, if it needs to change it's orbit (either from a lower to a higher orbit, or from a circular to an elliptical orbit), it needs to execute an Orbital Maneuver. This is accomplished by using a small impulse from thrusters to change the tangential …

Gazettale, BSP's premier interhostel competition, for which our team worked day and night, recently released the final standings.

And we're fifth.

Pop the champagne and dance, team, for we're fifth!


Jokes aside, I'm lukewarm about the result. Proud of what a ragtag bunch of people came together and assembled in …

Atomic Habits and Badminton

Posted on Mon 13 June 2022 in Writing • Tagged with Writing, Badminton

Atomic Habits probably needs no introduction, and neither will I bore you with one. All I'll say is that I found a friend in hostel with a copy of the book, and when I went home, I found a physical copy on my Dad's bookshelf (all of us have kindles …

Of Knights and Knaves

Posted on Wed 01 June 2022 in Writing • Tagged with Writing

Once every year, when the sun beats down
Students here become clowns
They think on their command, people will fall
But truly, they're just bricks in the wall
Misled by the mirage of power
Led astray till they flounder
"You're barely 20! What do you think will change
When you …

A Note on Random Variables

Posted on Fri 03 December 2021 in Mathematics • Tagged with Mathematics

$\newcommand{\triple}{(\Omega, \mathcal{F}, \mathbf{P})}$$\newcommand{\P}{\mathbf{P}}$ This note on random variables follows as a result of confusing notation in several math textbooks. I'll explain random variables (in measure theoretic terms) as verbosely as I can, and then prove some results. This article assumes that the …

How it Happened

Posted on Mon 02 August 2021 in Writing • Tagged with Writing

"Baba, I got Mathematics and Computing Dual at IITD", I told my father excitedly on the day the first round allocations were over. "It probably won't change now". Certain of this, I returned back to whatever I was doing, excitedly waiting for the seat allocations to get over (while simultaneously …

This summer

What is a dream? all of us think of dreams as abstract ideals, far removed from reality, that we should chase with all the effort we can muster every day.

Meditating on this a bit more, does this make sense? What is achieved by chasing an ideal when you can …

After using vim for a long time, I realized that vim would be very tricky to use for larger projects; there are a few reasons behind this, which are:

  1. Hard to set up and use autocomplete: I've tried omnicomplete, but it just didn't cut the mustard. I very seldom need …

The Last Time

Soft sunlight streaked in through the curtains, illuminating the room in a warm glow. Of course, I noticed none of that. The only thing I was aware of was my phone's alarm clock ringing. After drowsily hitting the snooze button, I realized that I had done this twice already, so …

I'll begin this article by brushing up a few definitions:

A function is a mapping between two sets: the domain D and the codomain C.

It's very important to note here that the function is the mapping itself, and not an element in the codomain or the domain. The function …

Sorting Testbench in C

I started reading CS theory in anticipation of my upcoming curriculum and I found that CLRS starts the reader off with sort algorithms (technically they start with math and basic CS, but I've already covered that). I decided to make a Sorting testbench, whose requirements were pretty simple:

  • It should …
