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.]]>

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).

Regular BB readers know one of my favorite head trips is the idea that we're living in a simulation or control system of some kind. Decades before The Matrix, folks like Jacques Vallee, John Keel, Stephen Wolfram, Rudy Rucker, Hans Moravec, and Ed Fredkin explored this notion. And of course it's also been the subject of countless science fiction novels. In recent years, Oxford philosopher Nick Bostrom developed a mathematical argument to support the mind-bending theory. A week ago, UC Berkeley mathematician Edward Frankel, author of Love and Math: The Heart of Hidden Reality, summed up the Simulation Argument in the New York Times Sunday Review and asked whether we can test the hypothesis.

*The Simpsons *is arguably the most successful television show in history. Inevitably, its global appeal and enduring popularity have prompted academics (who tend to overanalyze everything) to identify the subtext of the series and to ask some profound questions. What are the hidden meanings of Homer's utterances about doughnuts and Duff beer? Do the spats between Bart and Lisa symbolize something beyond mere sibling bickering? Are the writers of *The* *Simpsons *using the residents of Springfield to explore political or social controversies?

One group of intellectuals authored a text arguing that *The Simpsons *essentially provides viewers with a weekly philosophy lecture. *The Simpsons and Philosophy*, edited by William Irwin, Mark T. Conard, and Aeon J. Skoble, claims to identify clear links between variousepisodes and the issues raised by history's great thinkers, includingAristotle, Sartre, and Kant. Chapters include "Marge's Moral Motivation," "The Moral World of the Simpson Family: A Kantian Perspective,"and "Thus Spake Bart: On Nietzsche and the Virtues of BeingBad."

The authors do a great job of conveying the source material in clear, stepwise fashion, and made the wise decision to put the equations at the back of the book in an appendix called "The Math Cave." They don't delve deeply into any intermediate subjects like assessing correlation (for this, I highly recommend 1993's The Cartoon Guide to Statistics by Larry Gonick and Woollcott Smith, about which I can't say enough great and enthusiastic things), but that's probably a wise tactical decision. Confining the material to basics makes the whole work into an unqualified success.

The Cartoon Introduction to Statistics is a new book by Grady Klein and Alan Dabney that is a top-notch introductory grounding in statistical concepts told through a series of witty, funny cartoons that relate stats to everything from fish populations to alien opinion surveys. This is a *very* introductory text, and it assumes that you know nothing about stats -- not even why you'd want to know more about the subject. The book tackles both the task of providing a grounding in statistical concepts (mean/median, standard deviation, null hypothesis, random sampling, confidence intervals, etc) and explaining in clear and exciting ways why you'd care about any of this stuff.

Beast Academy is a set of grade three math textbooks and practice books structured as comic books about monsters. The books are "aligned to the common core state standards for grade three," if that matters to you. What's more significant is that they're actually really good math textbooks that introduce their subjects in a clear and easy-to-follow fashion, carefully linking each concept to the last; and the exercises are lively, fun, and built around stories that dovetail smoothly into puzzles, games, and other ways of putting the knowledge into practice. The monsters are great, too -- wonderful illustrations from Erich Owen, whose work you may recognize from the graphic novel adaptation of my story I, Robot.

A single surface model made by Alan Bennett in Bedford, United Kingdom. It consists of three Klein bottles set inside each other to produce, when cut, three pairs of single-twist Mobius strips. A Klein bottle has no edges, no outside or inside and cannot be properly constructed in three dimensions.
