A dimension is a physical quantity that can be measured, while a unit is a specific amount of a physical quantity. For example, time is a dimension, which can be measured in temporal units such as hours or seconds.
The boolean satisfiability problem (“SAT” for short) is arguably the most famous NP-complete problem in theoretical computer science. According to Wikipedia, it is “the problem of determining if there exists an interpretation that satisfies a given Boolean formula ”; or, in simpler terms, if there is at least one…
Visualizations and techniques for different maze generation algorithms.
Jean-Pierre Serre is a French mathematician who has made important contributions to algebraic topology, algebraic geometry, and algebraic number theory. He was a member of Bourbaki.
The following Python function computes the Fibonacci sequence , without loops, recursion or floating point arithmetic:
Find out how much math is involved in data science and what math you need to know to get started in a data science role.
Ok, this one is really best explained with a visualiser:
Database queries are a pretty surprisingly powerful tool that can solve seemingly intractable problems.
Can high school students really learn algebraic geometry? And what could it teach us about mathematics education?
[Photo by Alejandra Mavroski.] Myrtle called it The article that launched a thousand posts…, and counting comments on this and several other blogs, that may not be too much of an exaggeration…
It is the intelligent analysis of information that would be critical in a decade from now.
These days, the most common question I get goes something like this: A decade ago, you told people that scalable quantum computing wasn’t imminent. Now, though, you claim it plausibly is immi…
Nicholas Polson has, by my count using his SSRN page, already written 258 working papers in 2026 alone. He’s already written (or at least published to SSRN), six papers today, August 26, 2026.
Conrad Wolfram's 2010 talk on reforming maths education to teach real-world computational methods using computers.
The **Gaussian distribution**, or **normal distribution** is a key subject in statistics, machine learning, physics, and pretty much any other field that deals with data and probability.
My journey from building cricket bots to building “wind tunnels” with my collaborators — and finding the answer hidden in geometry.
Your security and privacy on the Internet (to the extent that such quaint notions still have meaning) depend on the difficulty of factoring certain large numbers. For example, take this 1,024-bit integer:
Fueling a revolution in cryptography and theoretical computer science through his breakthroughs in fully homomorphic encryption, leading to the possibility of more secure cloud computing.

Generalized data structure synthesis Loncaric et al., ICSE’18 Many systems have a few key data structures at their heart. Finding correct and efficient implementations for these data structur…
Layoffs are certainly one of the effects of battling COVID-19. What sort of unemployment rate might we see in the second quarter of 2020?
