What I learned today [Oct. 4th, 2006|11:59 pm]
[Current Mood |nerdynerdy]

~ gravity travels at the speed of light; nothing can travel faster than light

~ lightning will cause a compass to go haywire

~ how do the strings of string theory compile electrons, etc?

~ gravity is weaker than electro-magnetism (10^38 times stronger)

~ quantum mechanics is based on probability (?)

~ strong and weak nuclear forces (principles of atomic bomb)

~ radio-activity : weak nuclear force

~ the existance of black holes requires a unification theory of the theory of relativity and quantum mechanics

~ string theory : vibrations of energy

~ a black hole as the origin of the big bang (?)

~ if something is bumpy enough, it will appear smooth (I already knew this, but it is relevant)

~ Newton ranks higher than Einstein in physics circles

~ messenger particles create force

~ tachions travel faster than light

~ gravitons : massless particles

~ n = 496

~ resonance of strings responsible for physical properties

~ 11 dimensions, circular or as a line

~ extra dimensions "twisted and curled back on each other"

~ 20 fundamental constants of nature (caused by 6 dimensional shapes)

~ our universe as a slice of toast (brane), parallel universes compose loaf of bread ("the bulk")

~ wormhole : space bridge/tunnel; path of a string

~ Edward Witten

~ M = magic, mystery, or matrix (M theory)

~ dimensions : degrees of freedom

~ gravity may not be confined to our brane (closed strings)

~ theory - big bang as a result of two branes colliding

Yes, I am a geek. I watched this for fun.

"~ quantum mechanics is based on probability (?)"

It's in the sense that you can only make predictions based on groups of objects, like electron, protons, lightwaves.
When you start asking what happens to a SPECIFIC one in certain situations, you run into all sorts of very nasty problems.
