Looks like they can control spin to some extent.

That's the line I use to cope with it.

How about this little experiment: "...But when they subtracted a photon by passing a light pulse through a glass plate in such a way that a single photon bounced out, the pulse typically emerged with more photons rather than fewer..."

Odd stuff!

While not actually teleporting matter from place to place as in Star Trek, physicists have now plucked a quantum property from one atom and transmitted it to another. That feat of quantum teleportation, reported independently by teams in Austria and the United States in the June 17 Nature, moves scientists nearer to building a class of so-called quantum computers that's expected to be astonishingly speedy at certain tasks, such as scouring databases for specific information.

Hey, I have trouble understand car mechanics....actually, I don't I have a nice grasp of cars after working with mechanical engineers!

I agree...I always learned atoms like to be stable.
I have been reading a lot about string theory. It is interesting, but I don't get how they think it unifies everything from quarks up to the universe. Einstein explained so much with gravity at the "large" size, but quantum mechanics don't work with gravity.

Supposedly string theory works mathematically. But will we ever know and do a lot of physicists buy into it as the answer?
