CHAPTER I @rishirajrajgor

The Silence of an Overthinking Mind

A brief prologue on breaking things, reading books, and figuring out how the world works.

"The most important step a person can take is always the next one."

— Brandon Sanderson, Oathbringer

I'm a 19-year-old engineering student in Mumbai, exploring ideas at the intersection of robotics, embedded systems, control theory, and machine intelligence. Also I like math the way I like everything else: solve it, question it, visualize it, and keep going until it makes sense.

The stupidest way I can describe myself: part-time smart, full-time curious & dumb.

I build things, break things, and occasionally understand why. When I'm not doing that, I'm probably reading or chasing some random question that caught my attention.

"I keep asking questions until I can see the whole picture. Curiosity is asking why — and then asking why again."

CHAPTER II-1

Things I Built Instead of Sleeping (Or Reading Books)

Major architectures, models, and systems built from scratch.

"In theory, theory and practice are the same. In practice, they are definitely not."

CHAPTER II-2

Things I Built in a Single Weekend

Quick prototypes, hardware hacks, and ideas that started on a Friday night or Saturday morning.

"It worked on my machine at 3:14 AM, so we are calling it a success."

On My Desk & Reading Logs

Books, papers, and philosophies that rewired how I think.

"I have always imagined that Paradise will be a kind of library."

Crime and Punishment

Fyodor Dostoevsky

"Guilt, psychological unraveling, and the dangerous rationalization of an intellectual ego."

Currently Reading Cognitive Psychology

Thinking, Fast and Slow

Daniel Kahneman

"System 1 intuition vs. System 2 deliberation — how cognitive biases and heuristics dictate our choices."

Currently Reading Dark Epic

The Stand

Stephen King

"A sweeping post-apocalyptic saga on human nature, survival, and the clash between light and shadow."

Currently Reading Sci-Fi / Fantasy

This Inevitable Ruin

CHAPTER IV

Say Hello (I Don't Bite)

Where to find me when I'm not getting lost in books.

"The best conversations usually start with an unexpected question."

— The Way of Kings

Always open to discussing robotics, intelligent systems, embedded systems, weird engineering problems, and ofcourse good book recommendations.
