Brian Christian and Tom Griffiths' Algorithms to Live By: The Computer Science of Human Decisions is pitched as a combination of personal advice and business book grounded in the lessons of computer science, but it's better than that: while much of the computer science they explain is useful in personal and management contexts, the book is also a beautifully accessible primer on algorithms and computer science themselves, and a kind of philosophical treatise on what the authors call "computational kindness" and "computational stoicism."

Britain faces a major maths challenge. The challenge involves a **stock** of people and a **flow** of learners.

Meet Danica McKellar who as an undergraduate in college co-published a paper titled "Percolation and Gibbs states multiplicity for ferromagnetic Ashkin-Teller models on Z2," research that resulted in the Chayes–McKellar–Winn theorem. Oh yeah, before that, McKellar was Winnie on The Wonder Years.

Since its inception as a 2012 Kickstarter, the Reading With Pictures project has gone from strength to strength, culminating in a gorgeous, attractively produced hardcover graphic anthology of delightful comic stories that slot right into standard curriculum in science, math, social studies and language arts.

Statistician Patrick Ball runs an NGO called the Human Rights Data Analysis Group, which uses extremely rigorous, well-documented statistical techniques to provide evidence of war crimes and genocides; HRDAG's work has been used in the official investigations of atrocities in Kosovo, Guatemala, Peru, Colombia, Syria and elsewhere.

I have vague memories of my older scientist brother Mark wearing a slide rule in a leather case on his belt. It was really one of the first wearable computers, albeit a mechanical, analog one. Then in 1974, he was able to purchase a Texas Instruments SR-50, the first mass-market commercial electronic calculator. The slide rule was buried in Mark's desk drawer, where the SR-50, and later his Sharp Wizard, Palm Pilot, and their descendants would ultimately end up as well. (Mark died wearing a calculator wristwatch!)

In this episode of Numberphile, Alex Bellos explains the seduction of the slide rule and also the Halden Calculex, a device he calls the "iPhone of Slide Rules."

Pythagoras' Theorem, x^{2}+y^{2}=z^{2}, is true when x=3, y=4, and z=5. In fact, there are an infinite number of whole number solutions for Pythagoras' Theorem.

But there are no known solutions for x^{n}+y^{n}=z^{n}, when n equals any whole number other than 1 or 2. In 1637 mathematician Pierre de Fermat wrote in the margin of a book that he had devised a proof that there are no whole number solutions. The note was found 30 year later, and ever since then, no one has been able to prove it, though people have been trying for centuries.

This BBC documentary is about Oxford professor Andrew Wiles' lifelong obsession with Fermat's Last Theorem, which he read about when he was 10 years old. Wiles proved Fermat's Last Theorem in 1995. The proof is 150 pages long. If Fermat really did prove it, one can only guess how long his proof was. Read the rest

Mark says:

What would happen if you mixed a math education tutoring site with a late night 900 number?

Well, someone did, and it might end up being one of the strangest new startups out of Cambridge. It's called SolveX4U.com.

While this might look like a silly idea it's been gaining a lot of traction in the past week and the tech behind it is actually pretty advanced and useful for students who are looking for help with math, statistics and other subjects.

Anyone can submit any math problem and they will get help solving it (the first one is free too).

Derek Bruff teaches a first-year college writing seminar in mathematics, an unusual kind of course that covers a lot of ground, and uses a novel as some of its instructional material -- specifically, my novel Little Brother. Read the rest

Ben Kraft teaches a unit on gerrymandering -- rigging electoral districts to ensure that one party always wins -- to high school kids in his open MIT Educational Studies Program course. As he describes the problem and his teaching methodology, I learned that district-boundaries have a lot more subtlety and complexity than I'd imagined at first, and that there are some really chewy math and computer science problems lurking in there.
