Beneath the utilitarian purpose of computation, computing is also a source of delight and wonder . Software is not just databases and mail merges or SaaS and spreadsheets; it's creative coding and simulated cities , code poetry and bulletin board systems . It's websites that dazzle and iPhone apps that make the heart…

The Enrichment side of the "Accelerate vs Enrich" dichotomy in math education for kids who love math.

An interdisciplinary team of mathematicians, engineers, physicists, and medical scientists have uncovered an unexpected link between pure mathematics and genetics.
This summer, 3Blue1Brown launched the third installment of the Summer of Math Exposition contest. Every year, I’ve been impressed and inspired by the quality of some of the videos in this con…
In 2011 I gave a 15-minute talk to a lay audience in London. The topic I had chosen was ergodicity breaking, and the challenge was clear: how do you get this across? I invented a coin-toss gamble, which has since become a go-to illustration of ergodicity break
Read my manifesto on Code as an alternative to Mathematics. Code for this article can be found on this Colab Notebook should you choose to follow along. Why Kalman Filters? Kalman filters are ingenius. If you have never heard of them, then a very intuitive (and arguably reductive) way to think about them is to
Exact line rendering of smooth surfaces is harder than anyone would think
When you think about the Fibonacci sequence, you probably imagine a swirling vortex of oscillating points stretching outwards to infinity: Okay, no, obviously you don’t. Yet.
We thought we were accelerating fast enough. Turns out we weren't.
Conceptualizing functions as infinite-dimensional vectors lets us apply the tools of linear algebra to a vast landscape of new problems, from image and geometry processing to curve fitting and machine learning.
tl;dr: part 1 explains what an explanation algorithm is, and part 2 describes an open source SQL data differ.

High quality font rendering for WebGPU
We have public schools for a reason.
Statistical arbitrage (stat arb) is a pillar of quantitative trading that relies on mean reversion to predict the future returns of an asset. Mean reversion believes that if a stock has risen higher it’s more likely to revert in the short term which is the opposite of a momentum strategy that believes if a stock has…

Create beautiful diagrams just by typing math notation in plain text.
The single most undervalued fact of linear algebra: matrices are graphs, and graphs are matrices

Update: NIST released a draft that modified their recommendations (Oct 2024) 1) . RSA 2048 is to be only considered “deprecated” after 2030. The draft states:
Concise summary of the Hilbert transform: mathematics, effects on signals, and applications in telecommunications.

Once upon a time, my curiosity of dependent types transitioned into an endeavour to learn how they work under the bonnet. Then I found the paper called “A Tutorial Implementation of a Dependently Typed Lambda Calculus” or just “Simply Easy” – and began reading it. However, the affairs happening there were so complex…
“Will Vicktoreya Keyneslee Beauxpensees please come see the principal right now?” said the voice over the intercom.
Over the last several years, I’ve rewritten Rust’s regex crate to enable better internal composition, and to make it easier to add optimizations while maintaining correctness. In the course of this rewrite I created a new crate, regex-automata , which exposes much of the regex crate internals as their own APIs for…
Get up close and personal with Schnorr and his now patent-free linear signature algorithm.
As a physicist, I’ve learned that the presence of 2 π 2\pi 2 π [▼] [ Or rather τ \tau τ , as it should actually be called . ] in a formula usually spells trouble. It’s kind of annoying to write by hand, easy to forget, and it’s dimensionless, so you can’t easily check if you forgot to divide or multiply by it…
