I was looking through Instructables.com and came across this:

http://www.instructables.com/id/Paper-Noise-Maker/

I used to make this when I was really young. You just fold a piece of paper into that shape and flick it really hard. It makes really loud noises and scare the wits out of anybody nearby. Such fun!

And now for a bit of physics while we are at it: How does this work?

Basically, when the centre-fold of the paper gets flicked out, it moves at a very fast rate and pushes the air in front of it away quickly. This creates a shock wave which can be really loud.

Just yesterday, I read an online news that a ‘surfer dude’ with no university affiliation have published a paper about a theory of everything.

Not string theory mind you. A different one that marries gravitational field, Quantum Mechanics, Electromagnetism etc using E8. I admit I do not exactly understand what he is trying to say, but it is said that if his theory can actually predict ‘new particles’ which we can test and confirm then this might just be THE theory of everything.

Just a note la. If anyone’s interested to read his paper, it can be accessed through here: http://arxiv.org/abs/0711.0770

Have fun reading! (it’s 31 pages long) Gimme a summary *points to ‘comment’ link* when you are done with it okay?

Oh ya, the surfer dude’s name is A. Garrett Lisi.

I just came across this really interesting game (still in ‘beta’) called crayon physics and what it does is that it allows you to draw 2D images and see how they would behave if they were subjected to physics (or in this case gravity)

Basically you have a ball and stars. You are suppose to make the ball touch the stars by drawing shapes with ur crayon cursor so that the ball rolls towards the star without dropping down.

It’s really quite fun and you can download other levels when you become bored of the basic 4 levels found in the game.

The only thing I don’t like about it (for now) is the fact that you can’t draw much beyond rectangles and well… rectangles. The newer version (purported to come soon) looks really promising. Seems like you can draw all kinds of shapes and even cars. Fun stuff!

To play, download the game here

I have yet to play the games found in the latter website yet, I sure will do so really soon! Meanwhile, I can’t wait for the Crayon Physics Deluxe game to be finished!
