Gravity Waves Online Course
bgitac writes "CalTech has provided an online course on gravity waves by Kip Thorne. The course is described as "an introduction to all major aspects of gravitational waves." Prerequisites for this course are an understanding of classical mechanics. Weekly exercises and solutions as well as DVD quality videos of lectures are provided. The first couple lectures actually seem to be somewhat comprehendable!"
Originally read this one as:
Gravity waives online course
Gravity brushed off criticism that waiving the online course would hurt it.
"Look, I think it's safe to say that without me there would be no online courses. All Gore didn't invent everything."
Gravity went on to reassure everyone that the recent theft of the Principia did not affect it.
"Despite what you may have heard about things not existing until they are measured, etc, it is not the case that physical laws come into being only after they were described. I think that you will find through observation that I was alive and well before Mr. Newton's little revelatory experience."
Gravity also denied, again, that there was an assault and battery charge against him by Newton's heirs for the apple incident.
Liberty uber alles.
Don't they have their own tests for stressing their network? Or did they run all those and the only one left was the dreaded Slashdot one?
Sipping on Jolt and Dew. Laid back. With my mind of my cubicle and my cubicle on my mind.
Sounds like it would be some pretty heavy coursework. groan
I'm taking an intro GR course right now at my school. I would be totally lost if I wasn't able to ask my professor questions. This online course doesn't provide real-time interactions. They provide two e-mail addresses, but I'm not sure that would be enough for most students.
Physics: Making the universe open source.
Bwahahahaha, I just realized that the icon says 2 + 2 = 5. Considering how long I've been reading Slashdot, there are two possible conclusions:
1) the icon has changed recently
2) I have very poor observation skills
Shoot me.
For the Electron Compton Radius Rc = hbar / m c
and a Quantum Black Hole of Schwarzschild Radius Rsw = G m / c^2
the classical curvature R is given by
R = Rsw / Rc^3Therefore, the dimensionless measure of curvature fluctuation dR / R is given by
dR / R = ( Lp^2 / L^4 ) / ( Rsw / Rc^3 ) = ( Lp^2 Rc^3 ) / ( L^4 Rsw )so that
dR / R = ( Lp^2 Rc^3 ) / ( L^4 Rsw ) = ( Lp^2 Rc^3 ) / ( Rc^4 Rsw ) = Lp^2 / ( Rc Rsw ) == ( G hbar / c^3 ) / (( hbar / m c ) ( G m / c^2 )) = ( G hbar m c c^2 ) / ( c^3 hbar G m ) = 1
DVD quality videos and slashdot don't mix.

I would suspect this is the case. Prof. Thorne has written an excellent book titled "Black Holes and Time Warps", which is an explanation of the theory and science of both, and thier history, and this book (1/5" thick) was understandble completely by me, and I've only taken 1 college physics course. Kip Thorne, like Richard Feynman, seems to have a knack for explaining complicated things very well.

Here is a free online textbook on general relativity. Reviews on The Assayer would be welcome.
Find free books.
It's looking good, free education is always good.
;)
Too bad I don't belive in anything that's a theory.
You can try the excellent series of free books Light and Matter. It's an excellent overview of elementary physics.
Note: The "Simple Nature" textbook on the same site covers the same material as "Light And Matter" with a little more depth added. So it might be the choice of many slashdotters.

So, dR/R=1
that means what, exactly,in laymans terms? Or are you just trying to prove you know something that means little to the rest of us?
Not that I'm trolling or attempting some flamebait, but it's nice to know what one is talking about.
Water waves are an example of gravity waves. Gravitational waves are produced, for example, by merging neutron stars. Not the same thing.
it should be Caltech.
