SAT is often described as the "mother of all NP-complete problems." This post goes over what SAT is and why it is considered to be so important. A simple SAT solver is implemented using Python in the process.
Data Visualization can be a great tool for mathematical exploration and experimentation. In this article, I show you an example using Matplotlib and Python.
Judea Pearl and Dana Mackenzie sent me a copy of their new book, “The book of why: The new science of cause and effect.”
Why are election polls often inaccurate? Why is racism wrong? Why are your assumptions often mistaken? The answers to all these questions and to many others have a lot to do with the non-ergodicity…
Mistral Contrastin's thought bubble, blog, and personal revelations.
Presented in an experimental mnemonic medium that makes it almost effortless to remember what you read
Advice to claimers The Claimers The Claimers are a gang on the hit AMC television series The Walking Dead. They are the main antagonists in the second half of the zombie-apocalypse show’s Sea…

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.
An explanation of how the quantum search algorithm works, & introduction to the design of quantum algorithms
Investigation of Talebs claims about IQ using real data.
This morning I had a shower for 6.11686718 minutes. For breakfast I had 189.41576911 ml of fruit juice, followed by 75.24902503 g of muesli topped with 36.55668786 ml of milk and 15.44171338 g of yogurt.
"Minerva attack can recover private keys from smart cards, cryptographic libraries" , says the ZDNet headline. "The Czech team found a problem in the ECDSA and EdDSA algorithms used by the Atmel Toolbox crypto library to sign cryptographic operations on Athena IDProtect cards."

As discussed in Pattern Matching and Recursion , a well-known programming puzzle is to write a function that determines whether a string of parentheses is “balanced,” i.e. each opening parenthesis has a corresponding closing parenthesis, and the parentheses are properly nested.
You’ve probably played with model trains, for instance with something like the Brio set shown below.1 And if you’ve built a layout with a model train set, yo...
I have suspected for years that the classic buffet line system is a deeply flawed method, so I decide to simulate different methods to find out better ways
Over the past few years, deep learning has been taking by storm many industries. From voice recognition to image analysis and synthesis, neural networks have turned out to be very efficient at solv…
A much-abused result in mathematical logic , supposed by many authors who don't understand it to support their own favored brand of rubbish, and even subjected to surprisingly rough handling by some who really should know better.
We have established that there is a homomorphism called θ from B, the PROP of diagrams, to Mat, the PROP of matrices. To do this, it was enough to say where θ takes the four stars of the story so f…
I'm the kind of person who reads encyclopedias front to back just for fun, and I've been fascinated by mathematical special functions at least since my first encounter with the gamma function as a teenager. My work implementing numerical and symbolic algorithms in mpmath , Arb and other software projects during the…
I’m thrilled to report that I’m a co-author of the article “ An ultra-stable gold-coordinated protein cage displaying reversible assembly “, which was recently published in Nature . This work is the result of an exciting collaboration between biochemists, physicists, structural biologists, mathematicians, and others…
These remarks from “THE GENERAL AND LOGICAL THEORY OF AUTOMATA” 1947 are enormously insightful – no surprise. Von Neumann essentially predicts the emergence of the field of analysis of algorithms and algorithmic complexity. Not only does he point out the importance of understanding how many steps it will take to carry…
