Software · Mathematics · Ideas

Anub Sinha

I build software, and I write down the ideas underneath it — the small handful of plain things that quietly run the world. This is my library: the books I'm writing, the essays I keep, and the products I've put into the world.

Building at Opscale and LegalStreet, and writing the Applied series on the side. Say hello on LinkedIn or X.

The Library

Two volumes · more on the way

Each book takes one idea that quietly runs the world and chases it from the first principle all the way out to the machine it ends up inside — interactive throughout, and free to read in light or dark, on a laptop or a phone.

Volume I

Applied Mathematics

The plain ideas that run the world — geometric, binomial, Taylor, exponential and logarithmic series — each from its first principle out to the engineering it powers.

Open the book Volume II

Applied Computing

How computation actually works under the hood — opening with floating point: from a single bit to the silicon, and the format zoo that deep learning set loose.

Essays & notes

Mostly one stubborn question — "if it's just X, what was actually hard?" — pointed at results everyone calls obvious in hindsight.

EssayAlphaFold: if it's "just supervised learning," what was actually hard? May 2026 Pulling the protein-folding breakthrough apart to find the dozen quiet engineering problems hiding inside the words "just deep learning." EssayEsteva et al. 2017: if it's "just fine-tuning Inception v3," what was actually hard? May 2026 The first dermatologist-level skin-cancer classifier — and the unglamorous data work that actually made it go.
