Divide the number 999,999,999,999,999,999,999,998,999,999,999,999,999,999,999,999 into 1 and express the result as a decimal expansion, and you’ll find the Fibonacci sequence presented in tidy 24-digit strings: (Thanks, David.)
While attempting to learn Javascript and D3.js a couple months ago, I wrote a little library for displaying area proportional venn diagrams .
Bayes’ Theorem tells us how to rationally assess the probability of a certain statement of interest being true, given some evidence. Insofar as science consists in creating hypotheses, collecting e…
I have recently been going through my book Maths 1001 making updates for a forthcoming foreign edition (of which more in future). So I have been looking over mathematical developments since approxi…
The article here sums up pretty well the debacle that North American tournament Scrabble players have been faced with since the…
Clifford Algebra, a.k.a. Geometric Algebra, is a most extraordinary synergistic confluence of a diverse range of specialized mathematical fields, each with its own methods and formalisms, all of wh…

It is the intelligent analysis of information that would be critical in a decade from now.
Computer scientists from MIT find that a 40-year-old algorithm for determining the “edit distance” between symbols cannot be optimized any further.
A series by Eliezer Yudkowsky
The original question was: Another one of those questions of the type “does this make sense”. You have first derivatives and second derivatives. f'(x), f”(x) or sometimes dy/dx …
Our condolences Awesome Stories source John Nash and his wife Alicia were killed in a taxi accident on the New Jersey Turnpike Saturday afternoon. They were on their way back from Norway where he a…
In the previous post , we have seen how elliptic curves over the real numbers can be used to define a group. Specifically, we have defined a rule for point addition : given three aligned points, their sum is zero ($P + Q + R = 0$). We have derived a geometric method and an algebraic method for computing point…
Even after the Snowden revelations, there remained at least one big mystery about what the NSA was doing and how. The NSA’s classified 2013 budget request mentioned, as a priority item, R…

Those of you who know what public-key cryptography is may have already heard of ECC , ECDH or ECDSA . The first is an acronym for Elliptic Curve Cryptography, the others are names for algorithms based on it.
Attention conservation notice : Once, I was one of the authors of a paper on cellular automata . Lawyers for Wolfram Research Inc. threatened to sue me, my co-authors and our employer, because one of our citations referred to a certain mathematical proof, and they claimed the existence of this proof was a trade secret…
Transcript of Stephen Wolfram's talk at SXSW 2015 on the present and future of computing: Wolfram Language, image recognition, language-design philosophy, tweetable programs, computational thinking for kids, natural language as input, symbolic programming, deployment, automation of programming, Internet of Things…
History of mathematician Srinivasa Ramanujan’s lost notebooks and an exploration of solutions to those equations using Mathematica.
Glen Weyl has uploaded a new version of his paper, Quadratic Voting (written with Steven Lalley), to SSRN, which now includes the completed proofs. Quadratic voting is the most important idea for l…
I’ve been meaning to link to this post at the arXiv blog , which is a great source of quirky and interesting new papers. In this case they are pointing to a speculative but interesting paper by Martin Perl and Holger Mueller, which suggests an experimental search for gradients in dark energy by way of atom…

Systems thinker who ended up in data. Mostly working out why organisations can't answer their own questions.
An overview of my work on optimizing phone keyboard layouts for Swype and T9. There's some interesting history here as well as a novel simulation-based approach to keyboard optimization.
This morning I had the pleasure to be a mathematical guest in my daughter’s third-grade class, full of inquisitive eight- and nine-year-old girls, and we had a wonderful interaction. Followin…
