### This week in the arXivs…

### The interesting bits of today…

There are some quite interesting *bits* that came out today; here’s the list:

- Manifold — gravity bending action/puzzle game
- An Invitation to Higher Dimensional Mathematics and Physics
- DRM is Dead!

Quite a list, isn’t it?!

The first item is a little (flash? java?) game where the player has to create a ‘gravitational field anomaly’ in order to accomplish some tasks, e.g., jumping, avoiding sharp gears, etc. Quite neat! 🙂

The second deals with category theory in geometry and physics… but it’s a public lecture that Urs has to give. So, it’s *“category theory made easy”*! Maybe this can make some things more palatable to some folks! 😉

The last item is just self-explanatory: I’ll just sit and rejoice on Amazon’s probably best move… ever! 😎

Enjoy… 😈 !

Praqueles de vcs que têm acesso ao Orkut e que gostam de Física, eu recomendo o seguinte tópico na Comunidade Moderada de Física:

Acho que as discuss̀̀oes que apareceram por lá podem ser úteis para mais pessoas com dúvidas semelhantes — leitura massa!

Diversao garantida, []’s! 😈

### Tagging…

Well, in order to try to make life a bit simpler and add a bit of order to this chaotic world of blogging… i decided to start using *categories* (as WordPress calls them — *tag* is the name everyone else uses) based on the arXivs (as you can see in the posts below).

So, if you want, you can look for something like this… and, if more people start adopting this standard… maybe we’ll really be able to organize posts that deal with material from the arXivs in a comprehensive way. 😉

Have fun… []’s! 🙂

### The interesting bits of today…

Just to entertain until tomorrow… when the *real* entertainment comes to the masses (see this link on the 12Sep07 😉 )… i’ll leave some links:

- Stephen Hawking on Simpsons

- Icy calculations on a hot topic

Enjoy! 😈
