Physics Guide

Everyone's writing their own Physics Guides... Maybe it's because Chem had one but Physics didn't? Maybe it's because Physics is actually pretty manageable if you got the definitions and formulas nailed down? Maybe it's because we just all love Physics?

Whatever the cause is, it's really nice to see people trying to help each other out by distributing their guides. I have my own Physics guide written yes. But I don't feel like distributing it 'cause I really don't think it's good enough... Though I must say I like my layout better. =D

Looking through the distributed Physics guides [I've seen abt 3 i guess], I realise my own was kinda myopic in a way. I'd left skimpy details in Superposition... a lot of missing stuff. Like now-where do you find anything about path difference, phase difference, or the path difference required for constructive/destructive interference. I got the formula connecting path diff to phase diff though.

I guess I unconsciously excluded what I was afraid of [superposition], and only included stuff I like. Also a lot of stuff I expected myself to figure out intuitively, if not work out myself. Which might be a good or bad thing, depending whether you're rushing or have time to burn.

I do have a Physics guide that few in this world have though! An ODE.NET guide, which is a Physics Simulation Engine for C#!!! =D Yep, that's what I was working on, for the eve of the Prelims thus far. 'course, i did my revision lah! Except Maths. D= died-ed.

ODE = Open Dynamics Engine. Basically you have a geometry. Which is a shape for collision detection. Then you assign it a body. With a mass. That body will give it velocity, position, angular velocity, inertia. You advance the simulation by integrating the forces and momentum with time. Of course, you don't actually integrate! You just call a function. Then you take the values and render an equivalent object in DirectX or OpenGL.

There is not a single ODE.NET guide on the net right now. Mine is the first. =D =D Also there's very few ODE guides, which being the C++ version, you'd think have a lot of materials. But none. So mine is the few ODE tutorials out there too. If you have nothing better to do like me, you can see it here at http://cardinal4.wetpaint.com.

Man, coffee really makes you not wanna sleep. I'm amazed that it's already 1am, after a tiresome Prelim [Maths] paper, and not feeling the slightest fatigue. This is my first time experiencing such late-night energetic-ness. Lolz... only had my first cup of hawker kopi-o xiu dai [no sugar]. My parents' anti-sugar rally hehe.
