Whoa, lectures sux compared to sec school classroom studyings. They lecturer just goes on and on and he can't possibly pay attention to so many people, and that makes learning difficult. Ahhh, well. Things are starting to get bad, time to study hard soon, must jia you. 2 more weeks to results. Jokes is only for those who understand and are pro in Physics, I bet you don't understand it :D It's reflection and refraction.

Joke of the Week
When light passes from one medium to another, it obeys a set of partial differential equations (which "optimize" the path as it were). The light "slows down" for the amount of time it takes for it to solve the equations. But if the light is experienced enough, it can solve the equations faster than when it first started out.Truly retarded light has so much trouble solving the equations that it just gives up and bounces back into the original medium.
