# Vi Hart: Math Doodling

Remember that video about doodling dragons and fractals and stuff? I finally finished part 2! Here is a magnet link so you can dowload it via torrent. Here it is on YouTube: You can tell I worked on it for a long time over many interruptions (travelling and other stuff), because in order to keep myself from hating what was supposed to be a quick easy part 2, I had to amuse myself with snakes. Part of working on part 2 was working on part 3 and other related material, so the next one should go faster. Here was part 1, via Torrent or YouTube.

How To Slice A Bagel Along A Mobius Strip — And Why ​In the weeks before Doug Sohn closed down his legendary Chicago sausage joint Hot Doug’s, people were literally walking in the door and offering him a million dollars to stay open. This week on The Sporkful podcast, we’re featuring part one of our live show at the Taste of Chicago. I talk to Doug about why he walked away from all that money, and one of the top chefs in the world reveals his favorite candy bar. As part of our live show I also interviewed mathematician Eugenia Cheng, author of How To Bake Pi: An Edible Exploration of the Mathematics of Mathematics, who sliced a bagel along a Mobius strip live on stage.

Feynman point Pi's first few hundred digits contain ample double consecutive digits (marked yellow), and a few triples (marked green). The presence of the sextuple (marked red), dubbed the "Feynman point", in such a small sample is an intriguing anomaly. The Feynman point is a sequence of six 9s that begins at the 762nd decimal place of the decimal representation of π. It is named after physicist Richard Feynman, who once stated during a lecture he would like to memorize the digits of π until that point, so he could recite them and quip "nine nine nine nine nine nine and so on", suggesting, in a tongue-in-cheek manner, that π is rational.[1][2] Related statistics

Contents, Interactive Mathematics Miscellany and Puzzles Since May 6, 1997You are visitor number E66B7E in base 20 Raymond Smullyan, a Mathematician, Philosopher and author of several outstanding books of logical puzzles, tells, in one of his books, a revealing story. A friend invited him for dinner. 12 Mind Blowing Number Systems From Other Languages Today is a big day for lovers of the number 12, and no one loves 12s more than the members of the Dozenal Society. The Dozenal Society advocates for ditching the base-10 system we use for counting in favor of a base-12 system. Because 12 is cleanly divisible by more factors than 10 is (1, 2, 3, 4, 6 and 12 vs. 1, 2, 5 and 10), such a system would neaten up our mathematical lives in various ways. But a dozenal system would require us to change our number words so that, for example, what we know as 20 would mean 24 (2x12), 30 would mean 36, and so on. Does that blow your mind a little too much?

Ten Must Read Books about Mathematics Posted by Antonio Cangiano in Essential Math, Suggested Reading on July 17th, 2007 | 70 responses I love books with the ability to inspire readers. Many non-mathematicians consider mathematics as something abstruse and complicated, suitable only for ‘nerds’. Often I highlight the unfounded nature of this prejudice, but nothing is more effective at disproving this stigma than a good book. I was in fact able to quickly change many of my friends’ views on the topic, by just giving them a good book which shows the beauty and fascinating nature of mathematics and science in general.

Finding Unity in the Math Wars I usually avoid current events, but recent skirmishes in the math world prompted me to chime in. To recap, there’ve been heated discussions about math education and the role of online resources like Khan Academy. As fun as a good math showdown may appear, there’s a bigger threat: Apathy. And Justin Bieber. Famed number π found hidden in the hydrogen atom Three hundred and sixty years ago, British mathematician John Wallis ground out an unusual formula for π, the famed number that never ends. Now, oddly, a pair of physicists has found that the same formula emerges from a routine calculation in the physics of the hydrogen atom—the simplest atom there is. But before you go looking for a cosmic connection or buy any crystals, relax: There is probably no deep meaning to the slice of π from the quantum calculation. Defined as the ratio of the circumference of a circle to its diameter, π is one of the weirder numbers going. Its decimal representation, 3.14159265358979 …, never ends and never repeats.

Math Keeps Friends & Colleagues Together on 9/11 Memorial At first glance — and even after deep scrutiny — the names on a new memorial to those killed on September 11, 2001, seem randomly arrayed. The names are not arranged alphabetically nor, for the most part, are they presented in labeled groups. But the memorial's layout is anything but random. Research Supporting NCTM-Standards-Based Mathematics Education Reform » Mathematically Sane Research Supporting NCTM-Standards-Based Mathematics Education Reform By admin - Last updated: Sunday, October 24, 2004 - Save & Share - Leave a Comment Prepared by Eric Hart There is a rigorous and extensive research base for NCTM-Standards-based reform in mathematics education. A brief sample of that research base, related to several major themes of reform, is included here.

Great Literature Is Surprisingly Arithmetic A good book evokes a variety of emotions as you read. Turns out, though, that almost all novels and plays provide one of only six “emotional experiences” from beginning to end—a rags-to-riches exuberance, say, or a rise and fall of hope (below, top). Researchers at the University of Vermont graphed the happiness and sadness of words that occurred across the pages of more than 1,300 fiction works to reveal the emotional arcs and discovered relatively few variations. A different study coordinated by Poland's Institute of Nuclear Physics found that sentence lengths in books frequently form a fractal pattern—a set of objects that repeat on a small and large scale, the way small, triangular leaflets make up larger, triangular leaves that make up a larger, triangular palm frond (below, bottom). Why analyze the mathematics of literature?

How To Study Math How to Study Mathematics For an excellent web site with some great discussion of study skills check out the following site by Martin Greenhow. The site has some occasional comments pertaining to the school Dr. Greenhow teaches out but is non the less a great site that goes into much greater detail that I do here.
