Princeton University psych prof Susan Fiske published an open letter denouncing the practice of using social media to call out statistical errors in psychology research, describing the people who do this as "terrorists" and arguing that this was toxic because of the structure of social science scholarship, having an outsized effect on careers.

An anonymous Quora commenter has written an exhaustive and fascinating response to the question, "What is it like to understand advanced mathematics?" Read the rest
Britain faces a major maths challenge. The challenge involves a stock of people and a flow of learners. Read the rest
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.
(And just to confirm, Josh Saviano who played Paul Pfeiffer did not grow up to become Marilyn Manson.)
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, x2+y2=z2, 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 xn+yn=zn, 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
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).
