Quantum Physics 123: Wednesday 28 September

[There is a vase with roses on one side of the Doctor's desk as he returns to the room with a cup of coffee. He looks rather pleased with himself.]

Last week's homework is due now, please. I already have it from Lady Jessica, Ms Cally, and Mr McCoy. The rest of you have no good excuses, including zombies. Those who do not have it will be marked down.

Today we're going to move into the practical, namely, the presence of time travel in our respective worlds. We're going to have a discussion on this topic in class, and your homework for Monday is to summarise your own home dimension's views on time travel--for example, whether or not it is possible in any form.

So, let's get started.

Hands in homework (http://www.livejournal.com/users/time_agent/2706.html#cutid1).

As for the discussion, I can't imagine how time travel *wouldn't* be possible -- theoretically. I mean, we've got up/down, left/right, forward/back -- so why is time the only dimention to move strictly linearly?

I guess I'm gonna be late with the homework this time, but I promise to get caught up soon.

Homework

According to the Heisenberg uncertainty principle, on the smallest level (subatomic) of measurement, it becomes impossible to determine the location of an object. There is momentum, constant movement and therefore no ability to track or stop and measure the subatomic particles in order to determine where they are going or when they will stop.

::raises hand::

Am I supposed to stay after again?

[ten-and-chips.livejournal.com]

Not unless you feel the need to.

[sogothcally.livejournal.com]

Well, I've still got the same whole "can't really write" issue, sir. I don't want to fall behind or anything.

::her hands are still bandaged... in fact, bandaged more heavily than they were on Monday::

[ten-and-chips.livejournal.com]

[He looks at her hands, concerned.] No, of course you wouldn't. Are you going to be all right soon? Have you spoken to Doctor House?

[sogothcally.livejournal.com]

I've had it checked up on. I just, uhh, accidently reinjured myself on Monday night. I Fell on my hands, and, well... ripped the blisters right open.

[ten-and-chips.livejournal.com]

[He subconsciously puts his hand to his mouth.] My god. You must have been in quite some pain.

[sogothcally.livejournal.com]

Yeah... ::looks sad for a second::

It hurt, too.

::shakes her head, and blinks:: So, should I just stay after and talk through the time-travel stuff with you?

[ten-and-chips.livejournal.com]

(([facepalm]))

Certainly. I'm glad to accommodate your needs.

[sogothcally.livejournal.com]

Thanks! ::smiles, and goes to join her study buddies::

*turns in homework*

The Heisenberg Uncertainty Principle states that, essentially, you can never know the true trajectory of a particle, because the vary act of trying to observe the particle in order to measure it interferes with it's original path.

::nudges Domino with her elbow::

How's that whole Sparky-date thing working out for ya? ::grin::

[littleluck.livejournal.com]

...

Date? Hey, now. This is a homecoming thing!

...damnit. I still need a dress.

Sonia hands in homework, finds a seat, and busies herself taking notes.

[OOC: I would've tried to actually *do* something, but RL school is SOCRAZY right now, so next time? :( ]

*turns in absolutely brilliant work*

[phases-of-kitty.livejournal.com]

Hey, do you have notes from the earlier classes? I just added this class and I need to get caught up.

I'm Kitty, by the way.

[cyloninmyhead.livejournal.com]

*checks out the girl asking him the question -- damn, too young*

Hello, Kitty. I'm Gaius. Yes, yes I do have the notes. Here, feel free.

Maybe she has an older sister.

[phases-of-kitty.livejournal.com]

Thank you! I can't believe the school year's just started and I'm already behind.

By the way, do you know what happened to the computer science teacher? I was thinking of doing an independant study.

As far as I know, time travel is not possible in my world. Of course, it may just be that it's performed so rarely that only the time travelers themselves are aware of the process.

[ten-and-chips.livejournal.com]

[cocks his head] Despite the interesting mutation of the human genome in your world, none of those affected by mutation are able to control time? At least not that you're aware of? Fascinating.

In my universe, people have seen the future, although it has, so far, been impossible to actually travel through time.

An interesting side effect, incidentally, of seeing the future is that in the act of seeing, one actually in effect anchors the future. Once foreseen, never changed.

[ten-and-chips.livejournal.com]

That phenomenon may be unique to your universe, Lady Jessica. It is quite interesting indeed.
