Modern Physics

December 6th, 2007

I’ve written two more gazette articles in the past two weeks, but they aren’t up on the website yet.
In about half an hour I will go to the Dalplex to write my scariest exam yet: Modern Physics. It’s all on Einstein’s special relativity and quantum mechanics. I’ve been studying for it all week long. (I hate quantum mechanics so much.)
Instead of freaking out, I’m going to provide a collection of youtube clips that cover some of the material I need to know. Searching youtube for terms in quantum mechanics is so annoying because half the clips that turn up are for new-age ‘What the bleep do we know’ type groups that use the weird stuff in physics to support their loony beliefs.
Simultaneity in Special Relativity:

Quantum Tunneling:
This is what happens when a matter wave encounters any type of barrier. It means that electrons can sometimes go right through stuff, and that if you lean against a wall there’s a very very very minuscule probability that you will phase right through the wall.

Random Walks and Diffusion:
Not quite as simple as what we’ve studied, but pretty close.

Okay. Maybe I’ll just get wikipedia links instead:
Time Dilation
Length Contraction
Gravitational Redshift
Random walk
de Broglie Hypothesis
The Compton Effect
Heisenberg Uncertainty Principle
The Schrodinger Equation
Quantum Tunneling
That’s enough of that. No matter how difficult this exam will be, I know that I will be very relieved three hours from now.
Until next year, when I have to take Quantum Mechanics 1.
