What is Thread: Definition and 570 Discussions

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.

    String theory? sounds like a loose thread

    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...

    Group Story Thread: Write an Amature Author Creation

    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...

    Is our fate predetermined or do we truly have free will?

    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...

    History Is Fascism a Form of Paganism? Exploring Ancient Beliefs and Modern Ideologies

    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? eNtRopY

    The Ivan Seeking Conspiracy Thread

    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...

    Questions on Thin film interferrence (split from Snells law thread)

    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

    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...

    Complexifying Lie algebras (footnote to group thread)

    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...

    Fresh start at a (Loop) Quantum Gravity thread

    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 The two Ashtekar-Lewandowski 1994 papers seem to be basic in fact Sahlmann...

    Magnetic Monopoles: Exploring Vector Potential in a Doubly Connected Space

    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...

    Searching for Thread: How to Use Special Characters on Board

    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.

    "The Matrix" (De)Appreciation Thread

    [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...

    Are Insults Really That Difficult to Come Up With?

    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...

    How do you choose a thread? (misleading?)

    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...
