In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. The implementation of threads and processes differs between operating systems, but in most cases a thread is a component of a process. Multiple threads can exist within one process, executing concurrently and sharing resources such as memory, while different processes do not share these resources. In particular, the threads of a process share its executable code and the values of its dynamically allocated variables and non-thread-local global variables at any given time.
In sunny England, there is a 3 part tv programme type thingy on 'The Theory of Everything' in which string theory stars. I am one for embracing new ideas, but string theory sounds like a load of old hats to me. It may be the wishy-washy way that they present it with tons of special effects and...
I think you may be the first person to accuse the UFO crowd of lacking creativity.

This is me:
Now don't...
I had an idea, and we'll see how this plays out. The premise is simple. I'm sure you've all played that word game where you write a sentence or word at a time and see how it turns out. Same thing here, just in paragraghs. I'm sure greg will be happy to eat up less disk space:wink: So we're all...
Let's see ya... c'mon don't be shy
ok ok I'll go first
btw, please don't print this photo and throw darts at it... thanks
also when posting your own, for the database's sake try to optimize and crop as much as possible to reduce the file size.
who's read any Shakespeare? what did you read? how was it? any favorites? worst?
I've been reading a bunch of Shakespeare recently, including: Titus Andronicus, Macbeth, Julius Caesar, and i have a couple more coming along. i liked Titus a lot, Macbeth a little and i loved Caesar. but i...
Is it just me, or did the 'fate vs. free will' thread vanish? I know that approximately 7 hours ago I made my last post to that thread, and got a weird error saying that the page couldn't be displayed. After that, I got the same error when I tried entering any specific forum on PF. Now the...
I want to rediscover the religions of my ancient European ancestors and become a Pagan.
I suppose some of you already consider me one, but I think that there must be more to paganism than just mere hedonism.
Could someone give me some tips?

In the spirit of Psuedosciences all over the world:
Is it just me or do you see this Ivan Seeking character's name all over this section of PhysicsForums.com as well?
Could this be some conspiracy to dominate and monopolize the opinions and threads of the Psuedosciences section? Or is Ivan...
There are two things that bother me about the reemission idea.
The first is that the reemission has to be in discrete frequencies. So you'd think that many atoms together cause degeneration so that essential any frequency (say in the visible range) can be emitted.
Ok so far but what about...
Complexifying su(2) to get sl(2,C)---group thread footnote
On the group thread midterm exam (which we never had to take!) it says what is the LA of the matrix group SL(2, C)
and the answer is the TRACE ZERO 2x2 matrices.
So that is what sl(2,C) is.
When you exponentiate one of the little...
C will stand for the complexnumbers
Let V be a vectorspace over the reals.
V x V is the cartesian product, the set of ordered pairs (u,v)
We can turn that into a vectorspace over the complexnumbers
in what I guess is an obvious or at least very natural way which I'll spell out just for...
getting started in good order is difficult---reminds me of trying to furl sail in a high wind: there is a lot of subject-matter and it keeps flapping and getting out of hand----need to tie things down bit by bit

Magnetic Monopoly
Suppose you bent a long thin magnet around to make a closed loop. All the magnetic field would be contained in the body of the loop but outside the loop you would have a vector potential circulating around the body of the loop. The vector potential can circulate because the...
the "How Do You Pronounce... " thread
I'll start it off...
"ether"
is it "ee thur" or "eh thur"?

answer a question and/or put up your own word that you're not sure how to pronounce
Wasn't there a thread explaining how to use special characters on the board? I remember seeing one, but I can't find it for anything. I did a search for a few different keywords and I kept getting zero results.
If there was never a thread on this, then I guess I'm offically losing my mind.
[SOLVED] "The Matrix" (De)Appreciation Thread
I find it highly probable that the upcoming release of The Matrix: Reloaded will become the most successful movie of all time. Many of the fans of The Matrix adopt the cultish theories behind the movie, such as "There is no spoon" and that...
Do you know how some people will try to taunt you with corrupted versions of your name? I am pretty immune to insults directed at me, but the quasi-puns that some people produce are terribly base and contrived. (I myself can easily derive equally derogatory alterations, with similar conotations...
This is noway much of Philosophy but a question of your way in making (possibly) minor choices but isn't that the heart of Philosophy?
You log into PF, come to PF-Philosophy and see a set of new threads all open for discussion or you see someone has made a new post in some thread you'd said...
