<li><a href="https://www.youtube.com/watch?v=k7RM-ot2NWY">Linear combinations, span, and basis vectors</a> - "The fundamental vector concepts of span, linear combinations, linear dependence and bases all center on one surprisingly important operation: Scaling several vectors and adding them together."

That's what led me to create the Crackpot Index. But spending lots of time on newsgroups was still worthwhile, and it led me to start writing '<a href="http://math.ucr.edu/home/baez/TWF.html">This Week's Finds</a>', which has been called the world's first blog, in 1993. I also talk about my physics and math heroes, what discoveries I'm most looking forward to, and why I switched to thinking about environmental problems.

Three gods A, B, and C are called, in some order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, B, and C by asking three yes-no questions; each question must be put to exactly one god. The gods understand English, but will answer all questions in their own language, in which the words for "yes" and "no" are "da" and "ja," in some order. You do not know which word means which.

We are talking about Pi, 3.14159 etc, the number which describes the ratio of a circle's diameter to its circumference. How has something so commonplace in nature been such a challenge for maths?

Today the imaginary numbers are in daily use by engineers, and are vital to our understanding of phenomena including electricity and radio waves.

Are you interested in making ambient, drifting, densely-layered electronic music? But don't know where to even start? This is the most thoughtful and gentle introduction I'm aware of, from a fine musician. It's a 45-minute <a href="http://youtu.be/PH04VJ8jxvo">video workshop</a> from Rich Vreeland aka <a href="http://disasterpeace.com/">Disasterpeace</a>, composer of the gorgeous, acclaimed <i><a href="http://music.disasterpeace.com/album/fez-ost">Fez</a></i> soundtrack</a>. Rich composes a <i>Fez</i>-like track on the fly, explaining what he's doing in the process. While he uses <a href="https://www.apple.com/logic-pro/">Logic</a> and the softsynth <a href="http://www.native-instruments.com/en/products/komplete/synths/massive/">Massive</a> in this workshop, his general approach and attention to sound design and synthesis will be applicable to whatever software or hardware you choose to use. <small>(Hat tip to <a href="http://www.metafilter.com/user/35458">sparkletone</a> for the link. <a href="http://www.metafilter.com/tags/fez"><i>Fez</i> previously on Metafilter</a>.)</small> tag:metafilter.com,2015:site.147085Mon, 16 Feb 2015 12:28:00 -0800najuThe Man Who Tried to Redeem the World with Logic

<a href="http://nautil.us/issue/21/information/the-man-who-tried-to-redeem-the-world-with-logic">Walter Pitts rose from the streets to MIT, but couldn't escape himself.</a> Pitts was used to being bullied. He'd been born into a tough family in Prohibition-era Detroit, where his father, a boiler-maker, had no trouble raising his fists to get his way. The neighborhood boys weren't much better. One afternoon in 1935, they chased him through the streets until he ducked into the local library to hide. The library was familiar ground, where he had taught himself Greek, Latin, logic, and mathematics—better than home, where his father insisted he drop out of school and go to work. Outside, the world was messy. Inside, it all made sense. Not wanting to risk another run-in that night, Pitts stayed hidden until the library closed for the evening. Alone, he wandered through the stacks of books until he came across Principia Mathematica, a three-volume tome written by Bertrand Russell and Alfred Whitehead between 1910 and 1913, which attempted to reduce all of mathematics to pure logic. Pitts sat down and began to read. For three days he remained in the library until he had read each volume cover to cover—nearly 2,000 pages in all—and had identified several mistakes. Deciding that Bertrand Russell himself needed to know about these, the boy drafted a letter to Russell detailing the errors. Not only did Russell write back, he was so impressed that he invited Pitts to study with him as a graduate student at Cambridge University in England. Pitts couldn't oblige him, though—he was only 12 years old. But three years later, when he heard that Russell would be visiting the University of Chicago, the 15-year-old ran away from home and headed for Illinois. He never saw his family again. tag:metafilter.com,2015:site.146921Tue, 10 Feb 2015 18:13:50 -0800standardasparagusStill Combining Numbers On A Grid To Get Bigger Numbers, But Different

<blockquote>The best learning games are always fun. Try playing them yourself and see if <em>you</em> enjoy them. No matter how advanced your understanding of the subject matter, a good game should still be fun. I've understood algebra and number partitions for decades, but <em>DragonBox</em> and <em>Wuzzit Trouble</em> are still challenging puzzlers that I like to fiddle with on long airline flights. All good games offer challenges in intuitive ways. In fact, this is the reason games work so well for learning: Players are intrinsically motivated to identify and succeed at understanding the game's mechanics.</blockquote>
