Isn’t only a telephone. It can resolve Rubik’s Cube

The Rubik’s Cube is a 3-D mechanical puzzle invented in 1974.

On the site Shermix, I found a movie about Rubik’s Cube.
Its about a phone which took photographs on a real Rubik’s Cube, so, the phone thanks to a software, it could help a person to resolve Rubik’s Cube.

Puzzles like the Rubik’s Cube can be simulated by computer software.
In my opinion, computer science is an marvelous science, which is constantly amazed us.
In fact, is not only computer science, it also thanks to mathematics.
Its funny, because resolution of Rubik’s Cube is possible thanks to group theory in mathematics.
In second year, we learnt this theory, and we thought that was unnecessar.
It is proud maths are very important also in computer science. 🙂

Guess what? Group theory is also used in cryptology.
In fact a cryptological algoritm which called « RSA » is based on group theory.
This summer i used this algorithm to code a security software.

To see this movie :

Voici une nouvelle application de l'Iphone qui va vous permettre de finir votre rubik's cube...
