Scott Kim, Puzzles, and Games

Welcome to this week’s Math Munch!

Scott Kim

Meet Scott Kim.  He’s loved puzzles ever since he was a kid, so these days he designs puzzles for a living.  He’s been writing puzzles for Discover Magazine for years in a monthly column called “The Boggler.”  Click that link to look through some of his Boggler archives.  Here’s a cool one he wrote in 2002 about hypercubes and the 4th dimension.

Ambigram

In his 11-minute TED talk, Scott tells the story of his career and shares some of his favorite puzzles, games, and ambigrams.  It’s also completely clear how much he really loves what he does (as do I.)

Knights on Horseback – M.C. Escher

I’ve always loved “figure/ground” images, where the leftover space from one shape creates another recognizable shape.  M.C. Escher created some of the most famous and well-known examples of figure/ground art, but Scott Kim took the idea a step further – making an interactive puzzle game based on the ideas.  Naturally, the game is called “Figure Ground,” and it’s delightfully tricky.  You can even create your own levels.  Scott has a whole page of web games.  Go play!

Still hungry for more Scott Kim?  He gave a presentation for the Museum of Math‘s lecture series, Math Encounters.  You can watch the full-length video here.  You can also watch an interview he did with Vi Hart by clicking here.

Finally, after you read a Math Munch (or right in the middle) do you ever have a question you wish someone could answer or something you want explained?  Or do you ever wish we could help you find more of something you liked in the post?  Well we can do that!  Just leave a comment on the bottom of the page, and the Math Munch team will be very happy to answer.  We’d love to hear from our readers.

Bon appetit!

Rice, Rectangles, and Mathmagicland

Welcome to this week’s Math Munch!

Want to practice your math facts?  Want to help feed hungry people around the world?  Well, with Free Rice you can do both at once!  Every time you answer a question correctly, the website donates 10 grains of rice through the UN’s World Food Programme.  You can work on multiplication or pre-algebra, as well as vocabulary, flags of the world, and other subjects.  It’s good practice for a good cause!  What do you say?  Will you help?

Up next, meet Edmund Harriss.

I found him through his fantastic math blog, Maxwell’s Demon, but he’s also a visiting professor at the University of Arkansas and a mathematical artist to boot.  We’re going to take a look at his recent blog post, “the 2×1 rectangle and domes.”  I seriously encourage you to read the entire thing, but I’ll share a few highlights.  The 2×1 rectangle is called a domino, and when you cut one in half along the diagonal, you get a lovely triangle with nifty tiling capabilities!

Also, standard plywood comes in the same proportion (8’x4′), and they can be easily combined to make several types of domes, as you can see below.  Click here to see how a hexayurt is built.  Edmund goes on to talk about the truncated octahedron, and how we can use its shape to design these domes.  How amazingly clever!

Finally, let’s take a look at a classic Disney film, from 1959 – Donald in Mathmagicland.  Donald Duck, on some sort of hunt, finds himself in a very strange place, surrounded by numbers, shapes, and patterns.  The trees even have square roots!  Mr. Duck meets “The True Spirit of Invention,” a mysterious voice that leads him (and us) on an adventurous trip through Mathmagicland.  If you skip to 16:48 in the video, you can learn about Billiards, a game played on the 2×1 rectangle!  How fitting!

Bon appetit!
