proving that Preamble + 9th = (improve the world) and the job of the #25 logic look at USA Constitution
Archimedes Plutonium wrote: I am not pleased with the search results about Bentham's influence on the US Constitution and his influence on the Founding Fathers. I wonder if the Founding Fathers had Bentham's books when drafting the Constitution. I see where Bentham wrote one book in 1781, so th... 25 Mar 2010 04:39

False exponentials
Please forgive my ignorance. I failed math in school, but I just read an article about how 0^0=1, and I'm wondering if maybe there's something wrong the way that exponential notation is traditionally expressed. We think of 5*5 as 5^2, two fives multiplied by each other, and 5^3 as three fives multiplied. What... 5 Apr 2010 00:45

Direct Sum of Cyclic Submodules
Z[x] = ring of polynomials over the integers. Let R = {all f(x) on Z[x] such that f(x) = a0 + a2 x^2 + ... + an x^n for some nonnegative even integer, n, and the a's are integers}. We are asked to prove that the R-module Z[x] does not decompose into a direct sum of cyclic submodules. However, I do not see ... 22 Mar 2010 19:14

QUESTION: how are the 4 dimensions actually used in physics math?
Hi all, here is a question I wanted to ask about, regarding this concept of the Universe being 4-dimensional. The question is, how is this 4-dimensionality reflected in mathematic equations used to solve physics problems? For example, my understanding is (correct me if I am wrong) that before "time" was add... 21 Mar 2010 15:04
