Hi guys, For all you math geeks out there I decided to create a forum for math geeks to unite and discuss math and more math! (Of course, any one can join even if you aren’t a math geek). So if you’re bored and looking for something to do, feel free to check them out …

This is neat… the Inverse Graphing Calculator is like a backwards graphing calculator where you type something as your curve like “MATH FAIL”: and the IGC outputs an equation whose graph is the phrase: Sweet!

This may be useful… LaTeXSearch is a (free) service provided by Springer which allows the ability to search fo LaTeX code within publications. They use some sort of “similarity” algorithms to normalize and compare LaTeX strings so that, if similar equations are written slightly differently, the outputs are normalized and matched. Thus, if you come …

Theorem of the Day is a neat website that regularly presents a different theorem (or lemma, formula, etc). It’ll keep you busy for a while and an archive of the theorems can be found here.

“Evil Mad Scientist Laboratories” made some Sierpinski cookies that look delicious! To learn how to make them, go visit their site. Mike (from another website) decided to make fractal pizza (the site gives a 404-error now, but here is an archived picture of it):

Jim Propp’s self-referential aptitude test is quite interesting. It’s a difficult puzzle but here are some hints/spoilers: Q1 states that Q1-5 must have at least one B. Q3 states that the number of Qs with answer E is 0-4. Q4 states that the number of Qs with answer A is 4-8. Q6 Answer to Q17 …

A team of researchers has shown that no position of the Rubik’s cube requires more than 20 moves by using around 35 CPU-years of idle computer time donated by Google. The algorithms used by those fast cube solvers typically require more than 40 moves. “One may suppose God would use a much more efficient algorithm, …

Check out the site sixfoottallrabbit.co.uk/gameoflife where you can play Conway’s Game of Life (in html5). I was curious what the number 42 would produce, you know, since it’s the answer to life and all. This is my initial configuration above, the number 42. After a while, it evolves into the configuration above. Near the end, …

(crossposted from my main site) Hi math geeks (as well as nerds, dorks, and dweebs)! I wanted to give a shout out and huge thanks to all my subscribers and random visitors. Some of you already know that I also host SpikedMath.com where I like to post lame math comics. Without your readership, comments and …
