Forum Rules (Everyone Must Read!!!)

1] What you CAN NOT post.

You agree, through your use of this service, that you will not use this forum to post any material which is:
- abusive
- vulgar
- hateful
- harassing
- personal attacks
- obscene

You also may not:
- post images that are too large (max is 500*500px)
- post any copyrighted material unless the copyright is owned by you or cited properly.
- post in UPPER CASE, which is considered yelling
- post messages which insult the Armenians, Armenian culture, traditions, etc
- post racist or other intentionally insensitive material that insults or attacks another culture (including Turks)

The Ankap thread is excluded from the strict rules because that place is more relaxed and you can vent and engage in light insults and humor. Notice it's not a blank ticket, but just a place to vent. If you go into the Ankap thread, you enter at your own risk of being clowned on.
What you PROBABLY SHOULD NOT post...
Do not post information that you will regret putting out in public. This site comes up on Google, is cached, and all of that, so be aware of that as you post. Do not ask the staff to go through and delete things that you regret making available on the web for all to see because we will not do it. Think before you post!


2] Use descriptive subject lines & research your post. This means use the SEARCH.

This reduces the chances of double-posting and it also makes it easier for people to see what they do/don't want to read. Using the search function will identify existing threads on the topic so we do not have multiple threads on the same topic.

3] Keep the focus.

Each forum has a focus on a certain topic. Questions outside the scope of a certain forum will either be moved to the appropriate forum, closed, or simply be deleted. Please post your topic in the most appropriate forum. Users that keep doing this will be warned, then banned.

4] Behave as you would in a public location.

This forum is no different than a public place. Behave yourself and act like a decent human being (i.e. be respectful). If you're unable to do so, you're not welcome here and will be made to leave.

5] Respect the authority of moderators/admins.

Public discussions of moderator/admin actions are not allowed on the forum. It is also prohibited to protest moderator actions in titles, avatars, and signatures. If you don't like something that a moderator did, PM or email the moderator and try your best to resolve the problem or difference in private.

6] Promotion of sites or products is not permitted.

Advertisements are not allowed in this venue. No blatant advertising or solicitations of or for business is prohibited.
This includes, but not limited to, personal resumes and links to products or
services with which the poster is affiliated, whether or not a fee is charged
for the product or service. Spamming, in which a user posts the same message repeatedly, is also prohibited.

7] We retain the right to remove any posts and/or Members for any reason, without prior notice.


- PLEASE READ -

Members are welcome to read posts and though we encourage your active participation in the forum, it is not required. If you do participate by posting, however, we expect that on the whole you contribute something to the forum. This means that the bulk of your posts should not be in "fun" threads (e.g. Ankap, Keep & Kill, This or That, etc.). Further, while occasionally it is appropriate to simply voice your agreement or approval, not all of your posts should be of this variety: "LOL Member213!" "I agree."
If it is evident that a member is simply posting for the sake of posting, they will be removed.


8] These Rules & Guidelines may be amended at any time. (last update September 17, 2009)

If you believe an individual is repeatedly breaking the rules, please report to admin/moderator.

    Originally posted by anileve Also take into consideration that physists are just beginning as I have said before to prod at the implication of the superstring theory. Therefore it's complexity was due to the neglect of a physical approach rather than the mind baffling, formula infested mathematical approach.
    It's a little unfair to say that. For one thing, there is no way to physically verify superstring theory without the use of mathematics. The fact is, there exist no implications that can be tested or observed that are predicted theoretically. They are only predicted mathematically. The prediction, of course, is supersymmetry, which is a mathematical theory. Furthermore, a good deal of the complexity of the theory was alleviated through a mathematical approach, the Calabi-Yau inversion I have spoken of previously. The numbers involved were greatly simplified and many of the equations have since been very nearly solved and have hinted at other testable predictions. Granted, the insight came from mathematicians that were working on an unrelated problem, but that is part of the beauty of science and math, a strange confluence that is unintended but highly beneficial.

      Who did this I ask?!! Who split the thread? I demand some answers!!! Who the hell do these mods think they are? Professional editors working for an imaginary publishing company? Some people are just so hungry for power it's outrageous!

      On a more calmer note, the theory was not discussed in detail, so it's cool that we have a whole new thread dedicated to this glorious discussion.

        How did I miss this thread?

        Heeeeeeeeey. I just went to a lecture about this at Caltech.

        String theory connects the microscopic quantum world of elementary particles to the macroscopic world of gravity and geometry. Physicists believe that it is going to eventualy help them give a mathematical description of the microscopic laws that determine the properties of elementary particles and the forces that act on them, and help them explain the origin and evolution of the universe. Much has been achieved, but string theory is still a work in progress. I actually didn't know a single thing about the topic before I walked into the lecture. I called it my new thing learned for the week. It was a history lesson in string theory and a discussion about some of the problems that stand in the way of progress. It was pretty damn cool, actually.

          What's all the big deal with this anyway? This theory guesses that the universe should exist in 10 dimensions, contrary to the 4 of spacetime. Here they cleverly bring in the Big Bang guess to explain where the other dimensions went and that they "collapsed" or "disappeared" during the big bang. Perhaps a thread should be made to address the big bang. The problem I have with a lot of these Big Bang theories is that theoreticians can pretty much say whatever they like, due to the fact that it is impossible to look back to the early universe.
