Revisiting Make:'s weekly Math Monday column

As the editor-in-chief of the Make: website, I got to help develop column ideas and work with some amazing contributors. One of these was the brilliant George Hart (father of Vi Hart) from the Museum of Mathematics. After George left the museum, Glen Whitney took over the column. They both did an amazing job at demonstrating mathematical concepts in the most entertaining ways, using everyday objects and maker-made creations. You can see all of the installments of the series here.

Here is the briefest of samplings. The column ran (on and off) for eight years.

Math Monday, September 26, 2011

A mathematical haircut makes an unambiguous statement to the world that you love math. Here, Nick Sayers is sporting a rhombic coiffure with interesting geometric properties.

The obtuse angles of each rhombus meet in groups of three, but the acute angles meet in groups of five, six, or seven, depending on the curvature. In the flatter areas, they meet in groups of six, like equilateral triangles, and in the areas of strong positive curvature they meet in groups of five, but in the negatively curved saddle at the back of the neck, there is a group of seven.

To make your own, Nick suggests you use a rhombic paper template starting at the crown, work outwards, and make aesthetic decisions about the 5-, 6-, or 7-way joints depending on local curvature. This instance of the design was cut by Hannah Barker after a test version a couple of months earlier by Summer Makepeace. Read the rest

Different ways to prove that .999... = 1

In 2012, Vi Hart made this video giving "9.999... reasons that .999... = 1" She also made a video of bad proofs why .999... does not equal 1.

There's some interesting discussion about it at TYWKIWDBI. Read the rest

As usual, Vi Hart's annual Pi Day video is the best way to ring in 3/14

Vi Hart (previously) is the fast-talking, doodling, hyper-charming mathematical vlogger whose Pi Day videos are consistently the best of the season, even when she's pooping on Pi, she always manages to fascinate and delight. Read the rest

Vi Hart's statistical perspective on the American electoral divide

Fast-talking national-treasure math vlogger Vi Hart (previously) takes a statistical look at the polling data from the 2016 presidential election and concludes that the most significant divide in the country is "old vs young," which drives things like rural/urban (because young people leave failing rural areas for cities) and even racial divides.

Dallas police shootings and #blacklivesmatter

Here's the kernel of Vi Hart's #blacklivesmatter video, on how we remember the dead: "The officers who were killed are being treated with dignity and respect as they should be. No one reported about those officers’ past infractions or how many complaints had been made against them or their family members’ criminal records." Read the rest

Space Oddity meets Up-Goer Five

Alaska Robotics perform a very special cover of Space Oddity in constrained-vocabulary phrasing that restates the lyrics using only the 100 most common English words, in the style of Randall "XKCD" Munroe's Thing Explainer/Up-Goer Five.

Vi Hart on the relative sizes of infinities

Just in time for you to get the most out of "The Fault in Our Stars," the incomparable, fast-talking mathblogger Vi Hart's latest video is a sparkling-clear explanation of one of my favorite math-ideas: the relative size of different infinities. If that's not enough for you, have a listen to this episode of the Math for Primates podcast.

Vi Hart's updated poop-on-Pi video

Math-doodling manic talking charming vlogger Vi Hart has updated her classic anti-Pi rant with a new poop-on-Pi video called "Happy Pi Day? NOPE," in which she explains why we should be wowed by numbers like 4 and 5 and completely blase about Pi and its cohort. Read the rest

Cookie geometry with Vi Hart

Vi Hart, the Internet's favorite manic vlogging mathematician, has released a new video in which she teams up with math artists Andrea Hawksley and Gwen Fisher, and Gwen's sister Ruth of Sweets by Ruth. The four of them bake satisfyingly precise and geometric gingerbread polygons, then build up a variety of astounding three dimensional forms by piecing them together with icing. The video is both hunger-inspiring and brain-inspiring, and is likely to be the best thing you watch this week.
