Entanglement already doesn't violate relativity, as it doesn't allow FTL information transfer.

But I thought John Francis Clauser did experiments that showed that the particles were in fact connected in some manner and not pre-determined?

Right, but there's no way to use measurements of the particles to transmit some sort of message.
Could you clarify that?
[QUOTE=mac338;35447358]Could you clarify that?[/QUOTE]
Even if you measure and entangled particle, there's no way to know if the state you measured was the initial random state or the complementary state because the first particle was already measured until you compare with someone who measured (or didn't measure) the other particle by slower-than-light means.
Even classically, things can move faster than light if they carry no information. Phase velocities of waves can travel faster than c because you can only encode information via the group velocity, which is bound by the speed of light.

Woah, shit I didn't know.
I'm gonna need more books! This stuff's fascinating as fuck. I gotta wrap my head around it all.
But I did know the first part, I just figured since I read about the John Francis Clauser experiments there was some fancy workaround I hadn't fully understood. I'll make a note to check deeper into that too.
Keeping in mind I decided to begin learning about quantum mechanics two days ago.

God theoretical (and classical) physics are amazing, I thought reading about things would close my mind to many things, but if anything learning about quantum mechanics, string theory, relativity, black holes and stuff like that is liberating, so many possibilities. It really makes me joyful crazy as it sounds.
I think general relativity is my favorite area of physics so far. Such a simple premise that explains pretty much everything we see on everyday and astronomical scales.
It completely changed my view of the world, I had a Newtonian view before. Now it's just... woah.
-incredibly bad reading-
[QUOTE=Cree8ive;35431169]I'm really interested in microbiology and I'm currently looking at the US as my designated country of university/college, more specifically in the state of California.
Anyone here have experiences with either and could tell me a bit about it?[/QUOTE]
Anyone?

[QUOTE=Jo The Shmo;30128844]Science is awesome.
I've loved science for as long as I can remember.
And every year when I'm introduced to a new type of science that I never really cared for it turns out I love it too.

"flagella might look silly but those short microtubules look even cilia!"
I thought of that when taking bio notes this morning.[/QUOTE]
Physics is awesome!
And the negative side of Einstein's and Newton's calculations is that no object with a rest mass can achieve the speed of light, let a lone a spaceship sitting in a dock.
did a physics lab at MIT on wednesday
it was just a field trip thing with my high school but it was fun
Here's a haiku

YOU WOULDN'T MANIPULATE SOMETHING INTO A CAR
We have already created artificial materials, that's pretty cool. :v:
I feel like such a badass reading trough our course-material about the Schrödinger equation, the Pauli principle and other quantum physics related ideas.
Too bad I only attended 1 lecture and don't understand crap...
[editline]10th April 2012[/editline]
time to do some panic studying before the assignment deadline.
Hey, is it possible for a hydrogen atom at ground state to absorb a photon with the energy 13.6 eV? I mean what happens to the electron?
Guess who's failing quantum mechanics.
I fell behind in the middle of the semester and I'm catching back up now (thanks to this awesome textbook, Shankar's [I]Principles of Quantum Mechanics[/I]) but I don't know if I can fix my grade by the final. Might have to drop it and take it again later. Good thing I haven't used any of my two free withdrawals so I can drop it without any grade penalty.
Look what he got to play around with :

Don't breath this, it's radioactive!
I am confused. Explain?
[QUOTE=Dacheet;35672452]I am confused. Explain?[/QUOTE]
imagine it's a gamma source with a nice big wall of lead bricks around it
Sup, taking chemistry and maybe biology next year.
I failed quantum mechanics quite epicly. Didn't understand anything, I guess there are limits to my imagination :rolleyes:
also my sciencey thing is way cooler to look at

oooh that looks neat what does it do?

It makes PLASMA!
[QUOTE=mike;35672871]imagine it's a gamma source with a nice big wall of lead bricks around it[/QUOTE]
Yup, we had two gamma radiating sources CS-137 and CO-60 that shot their photons up to the tube which was connected to the computer. We then proceeded to block the gamma sources with different materials to calculate their gamma absorption coefficient.
It was quite fun.

Normal "ST" in high school, or a different course?
Taking the IB myself, and hell, I am getting fucked up in Chemistry, but I love the subject.
