Hey, but you're all clamering out there "what about the uncertainty principle, can you really measure things that accurately?" Well quantum theory tells us that the precision with which we can measure position and velocity of any particle are limited by a very simple formula:
If we want to measure each atom to within a typical atomic size this means that the velocities will be uncertain by about
300 meters per second (if the particle weighs as much as a Hydrogen atom say). This sounds fast, but it's not so bad. The
ordinary jiggling of our atoms due to us being at room temperature is bigger than this by a factor of three or more. In other
words, the uncertainty principle doesn't appear to be too restrictive in terms of how well we can measure those atoms

I dont see the problem. You are assuming that teleportation here is "real" teleportation; actually moving a person from one point to another. I dont believe that they are doing that. They are destroying the person at point A and recreating him at point B. Why would he be moving at the speed of point A when he's rebuilt at point B?Another thing to address. Say you CAN overcome Heisenburg and are able to measure the exact possition and velocity of every particle. What happens if you transport someone from the equator (moving at roughly 1038mph) to the North poll (moving at 0mph)? They will splatter against the side of the telepod. :Q
I thought the Heisenburg Uncertainty principle was that you can never be sure where a particle is, in order to be sure you must expose it to light, therefore moving the particle from its previous spot, so you can't know where they were.Originally posted by: AmusedOne

who he?
Werner Heisenberg
He states, more or less, that the more you know about one aspect of a subatomic particle, the less you can know about the other.

You cannot measure position and velocity at the same time.Originally posted by: Skyclad1uhm1You would need to make sure that all the chemical and electrical processes of the body continue in exact the same way, and that all the particles of the body reappear at exact the same distance to eachother, with the same speed and direction they had before, and at the same time.
\That's where Heisenberg comes in. You cannot measure position and velocity at the same time.

This would be great for space travel. I'd teleport myself, but not recreate my self on another end... just put the info on a ship and send it out to some other part of the galaxy. Then at some time I will recreate at some pre set time and 1000s of years may have past and I'd be in another place, and if it sucked, I could re-teleport myself and try again. It would be better to know where you're going though.
I can see this being useful on earth too. Damn this decade sucks. See you all in 10 yrs! ZAP!
or
I can't wait till the 3Ghz AMD comes out! ZAP!

I believe when he said "soul" he was talking about personalities, memories, feelings, etc. If you destroy a human at one end of the transporter, and recreate them at the other end, to they retain their memories, and personality?
Whoa, settle!
If your memories and personalities are nothing more than 'data' in the brain, then yes, you retain them. Lucky for us there is no soul.![]()

Okay, you guys have this pretty much right in theory, but all wrong in practice. Here is what I remember:
Heisenberg's Uncertainty Principle: dxdp >= h(bar)/2
Verbally: the "fuzziness" with which you measure a particle's position, multiplied by the "fuzziness" with which you measure a particle's momentum (read: velocity) has to be greater than h(bar) (some VERY VERY VERY small number) divided by 2.
You can measure both velocity and position at the same time, and each with whatever precision you choose, but the precision with which you measure both at the same time has some fundamental limit.
Please know that this limit is so insanely small that the displacement of an atom governed by this principle probably wouldn't have an effect as to whether or not you could re-create a person.
A quick thought: Ever dropped a baseball? Did you see it fall to the earth? Did you ever think that the earth also "falls up" to the baseball (it actually does)? Do you ever account for the fact that the earth falls up to the baseball when you're going to catch a fly ball? Probably not. If my 10-second-do-it-in-my-head-without-looking-up-any-numbers-to-see-if-they-are-right-yet-am-still-pretty-sure-about math serves me, the distance that the earth falls up to the baseball after a 2 metre drop is still almost 10^20 times larger than the distances we're talking about with Heisenberg.
