Today Alan Turing would have been 100 years old. To celebrate it, I marked this day to start reading his biography (in fact, this was one of the reasons I wanted to finish reading the previous book earlier this week).

In fact, I am not the only one to celebrate this. There are lots of news in the media and Google celebrated with a nice Doodle, changing its logo for a Turing Machine-like game (as you can see here).

As a physicist, I am happy to see how a mathematician changed the world… and how the world celebrates it.
