    Creating noncyclic groups of certain order

    We'll in some cases I can but for example if the order is 25 I can't think of one that is NON cyclic, otherwise it would be easy.

    Creating noncyclic groups of certain order

    How would I construct noncyclic groups of whatever order I want? For example g is order 8.

    Proof involving the sum of squared integers

    Sorry I'm on an ipad and was being lazy haha. Let p stand for "the numbers in that set cannot be written as two squared integers" and Q stand for "at least one number in the set can be represented as three integers squared." How should remainders be used here?

    Proof involving the sum of squared integers

    Homework Statement Theorem: the numbers in the set {99, 999, 9999, ... } cannot be written as two squared integers, but at least one can be expressed as the sum of 3 squared integers. Homework Equations Well there are a lot of examples but let's go with 32 + 32 + 92 = 99 We may...

    What is the best way to learn sequences/series?

    2 people I always recommend. Www.patrickjmt.com http://www.khanacademy.org/math/calculus/sequences_series_approx_calc It also helps to play around with things like the Cantor set for fun and to familiarize yourself with the techniques used.

    Are There Any Conjectures About the Primality of n and n!+1?

    I'm not sure if these have been looked into extensively (they probably have, I just have a hard time finding them), but I was just wondering about a couple conjectures I thought up and tested by hand for a bit. Matlab can't run it for very long. Let me know if anyone finds a contradiction or if...

    Neutrinos faster than light speed? What do you guys think?

    Yes I realize at lightspeed 60 nanoseconds means a lot of distance covered but its still too close to the "barrier" of lightspeed to come off as anything but an error in calculation or a malfunction. Were talking a fraction of a second here.

    Neutrinos faster than light speed? What do you guys think?

    I feel like this is one of those things where they say "oh my god this will change physics forever" but it ends up being being incorrect. Either way it is odd that they would measure faster then light speed at all, I'll give them that. But 60 nanoseconds? Not quite enough to make me convinced...

    Creating a MMO in the Universe: Spacetime Online

    First of all, as long as this is merely a science fiction scenario, I doubt people will care about what is correct / incorrect. If you really do care though I might add a few things. 1. How did these large stars collide? You need a backstory to that because unless galactic canabalism is...

    Matter can neither be created or destroyed

    Yeah there is really no point in discussing any events before the big bang (other than the fact that it is nice to have more people interested in science topics). It's good to be curious but as to what really happened, that's a different kind of physics; the kind with a "meta" in front of it.

    Cosmology: a good career choice?

    Thats actually pretty cool. As long as I am using my brain. I would however like to be working with something science related too. If possible of course.

    Cosmology: a good career choice?

    Explain please haha. I fail to see how banking relates to physics. Programming I could see I suppose.

    Cosmology: a good career choice?

    It would be cool to start this thread up again. I'm starting to have some "fears" that a double major in physics / astronomy will still leave me with a low chance of doing actual physics and astronomy as opposed to banking and or computer programming. O__o

    High School senior confused in life

    Well I suppose I can climb in this boat with you. We basically have the same interests, but I like the cosmology side more than the engineering side. I'm going for a double major in physics / astronomy and will see what happens after that, just remember that atleast you will have a very good and...

    How can I truly learn Calculus without going through the basic steps?

    I think you're probably right. I was just worried calc 1 in particular would be too rushed for me.
