Robocup 2015: Exciting Robot Football Save.
Join the Simple Science and Interesting Things Community and share interesting stuff! https://plus.google.com/communities/117518490246975838002

RoboCup is an annual international robotics competition proposed in 1995 and founded in 1997. The aim is to promote robotics and AI research, by offering a publicly appealing, but formidable challenge. The name RoboCup is a contraction of the competition's full name, "Robot Soccer World Cup", but there are many other stages of the competition such as "RoboCupRescue", "RoboCup@Home" and "RoboCupJunior". In 2014 the world's competition was held in Brazil. RoboCup 2015 was held in Hefei, China

Dear +Google Play, I'm sure you hear this all the time, but I love you and more than any other tech obsessed media junky. It's that pathological adolescent kinda love that inspired Shakespeare. Think of a Justin Bieber fan, but instead of squealing, it's this insistence that we always watch stuff via Chromecast and sycophantic posts online (see: this post).

But I'm having a minor problem with subtitles: I can't turn them off on my Spanish-language movies and none of them seem to have the option of Spanish subtitles (both are options that are on every DVD I've bought and are important to those of us who are trying to keep up their Spanish in parts of the country where it isn't spoken much).

Lots of love. Keep it sexy.

Nice writeup showing that computer science is the STEM field with the most job opportunities relative to the number of graduates, and that most STEM fields actually have an oversupply of graduates relative to job openings. Nice quote in the article: "So why do 90% of our public schools teach math and science but no computer science?"

Wallace-Bolyai-Gerwien theory is the theory that any two polygons are equidecomposable. 
That is that one can be cut into finitely many polygon pieces and be rearranged to obtain the second polygon.

In geometry, the Wallace–Bolyai–Gerwien theorem, named after William Wallace, Farkas Bolyai and Paul Gerwien, states that any two simple polygons of equal area are equidecomposable; i.e. one can cut the first into finitely many polygonal pieces and rearrange the pieces to obtain the second polygon.

"Rearrangement" means that one may apply a translation and a rotation to every polygonal piece.

Unlike the generalized solution to Tarski's circle-squaring problem, the axiom of choice is not required for the proof, and the decomposition and reassembly can actually be carried out "physically"; the pieces can, in theory, be cut with scissors from paper and reassembled by hand.

The theorem can be understood in two steps. First, every polygon can be cut into triangles: for convex polygons this is immediate, by cutting off each vertex in turn, while for concave polygons this requires more care. Each of these triangles can then be converted to a right triangle, by dropping an altitude (that is, drawing a line perpendicular to the triangle's base and through the top vertex). This is sufficient to easily compute the area, as each right triangle is half a rectangle, or alternatively can be cut halfway up to be reassembled into a rectangle. The second and subtler step is that each right triangle (or equivalently rectangle) can be decomposed into a rectangle with a side of a given (unit) length. Once this is proven, it follows that every polygon can be decomposed into a rectangle with unit width and height equal to its area, which proves the theorem._
