The wikipedia-like repository for mathematical “tricks” has now gone live. Their mission statement:

The main body of the Tricki will be a (large, if all goes according to plan) collection of articles about methods for solving mathematical problems. These will be everything from very general problem-solving tips such as, “If you can’t solve the problem, then try to invent an easier problem that sheds light on it,” to much more specific advice such as, “If you want to solve a linear differential equation, you can convert it into a polynomial equation by taking the Fourier transform.”

According to Wikipedia, Wapedia brings the contents of Wikipedia to mobile devices like mobile phones and PDAs. I might say that Wapedia is an optimized version of Wikipedia for mobile phones.

It’s hard to think about life without Wikipedia these days. I use it for getting summaries about stellar clusters (Messier or NGC). I use it for learning theories in astrophysics. I use it for reminding me the functional forms of various distributions and their moments. I use it for getting definitions of scientific and engineering jargon. And I use it for many many reasons.

Probably if someone gets along well with electronic gadgets, they already use Wapedia. It might be a cliche. Then, can you help me? I like to hear how people handle cheating with cell phone when one can retrieve any information through Wapedia during exams. I believe some sloggers are in education.
