    Edge of universe?

    I'm not a physicist! Just wondering what it is like on the edge of the universe? how many dimensions will be there, what force will be acted upon a close object, and what relativity will become? I'm assuming the universe is euclidian (eucklidean? euclidean? my English sucks.) not hyperbolic or...

    Why do people think red shift is caused by big bang?

    Question: as title says. I'm not a physicist at all and I do not know much about how people obtained the big bang theory from red shift. So here is what I thought from red shift: In a time period t1, a distant body emits a light wave with a certain amount of energy with n oscilations(I dont...

    Simple question about logs

    if x^a=b (a,b are constants) then there are two ways of finding x: root and log so for example, x^2=4 by root: (x^2)^(1/2)=(4)^(1/2) x=\pm2 by log: 2 ln (x) = 2 ln 2 x=2 but it is yet impossible to obtain the negative x from logs. How are you supposed to do it? And heres a few...

    How should continue on my study?

    I'm a High School student in NZ, and Im going to the local university next year. However I dont know what subject should I choose, I perfer pure mathematics, although engineering or computer programming may have much higher incomes so Im considering them. I am very good at mathematics (I studied...

    Is there a theory about one-sided equations ?

    Is there a theory about one-sided "equations"? I am working on infinity recently. Trying to define the 'indirect' result of infinity as 'range of numbers'. So its like: if there is a set A of infinite elements, f(x)=a\wedgeb\wedgec\wedged..... (a,b,c,d...\inA); However, one cannot say a=f(x)...

    Questions about the logic of infinity

    I asked a question related to infinity a few weeks ago, but the answer I got really lead me to a confusion. Is there any way, that infinity can be compared in another plane or whatever. So here is something paradox if you treat infinity as it is in the set of real numbers...

    Can someone just help explain a clear defination of superlog?

    I was trying to understand superlog and superroot but I get only 3/4 of them. Can anyone just explain, in a non-textbook way, such that: I can understand without any post-calc knowledge http://en.wikipedia.org/wiki/Superlog ------------------------------------------------- or just explain...

    A counter-example to the Gelfond–Schneider theorem

    Gelfond–Schneider theorem can be seen here(http://en.wikipedia.org/wiki/Gelfond%27s_theorem) wiki. ---------------------------------------------------------------------------------- Given a simple calculation: a^b where a<0; and let b be a fraction : u/v so there are 3 possible ways of u...

    1 to the power of ∞ =e ?

    1 to the power of ∞ =e ????? Let there be function f(x): f(x)=(b+1)^(b+1)/(b+1!)/[(b^b)/b!] --an example of f(99): 100^100/100!/(99^99/99!) ------------------------------------------------------------------------- and as b gets larger, f(x) converges to e. so we have: lim b→ ∞...
