Sep 24	comment	Isn't this a problem when evaluating the auxiliary equation? What exactly did you enter in Wolfram Alpha? Because I get "$0$ assuming $\alpha>0$"
Sep 24	answered	What is the difference between an array and a vector?
Sep 23	comment	Proof: If n is a perfect square, $\,n+2\,$ is NOT a perfect square That proof only works for $n>0$ (but for $n=0$ it's easily checked directly).
Sep 23	revised	Some quick math problems I'm stuck on fixed a mistake in the explanation
Sep 23	comment	Is probability objective? Well, the last case would be for example if Bob eats the white ball twice as often as the black ball, the probability of the box containing the white ball is $1/3$, which is neither $0.5$ nor $0$ nor $1$. And yes, people disagree about the correct interpretation of probabilities.

Sep 23	comment	Is probability objective? If you are a Bayesianist, both are right. If you are a frequentist, it depends on whether, when repeating the experiment many times, Bob would choose the same ball each time (then Bob is right), would choose each ball equally often (then Alice is right), or would only show a certain bias for one color (then neither is right).
Sep 23	revised	Please could someone explain what P(A $\cup$ B) means? and how you know what its out of? added 167 characters in body

Sep 23	comment	confusion over the use of universes in category theory And I fixed the even i. :-)
Sep 23	revised	confusion over the use of universes in category theory fixed another i
Sep 22	awarded	Nice Question
Sep 22	comment	Selection through identical balls Unless you are doing quantum mechanics, "identical" things don't exist.
Sep 22	comment	Are there infinitely many “super-palindromes”? BTW, for the primes of the form $10^k+1$ there's already another math.SE question. Note that according to the discussion linked to by one of the answers, there are no primes for $2<k<16777216$.
Sep 22	comment	Are there infinitely many “super-palindromes”? @MichaelAlbanese: Since all primes of the form $10^k+1$ are palindromic primes, this would imply that there are infinitely many palindromic primes (which as I mentioned is an open question). You are right that it would be sufficient for there to be infinitely many palindromic primes, though.
Sep 22	reviewed	Approve suggested edit on Are there infinitely many “super-palindromes”?
Sep 22	comment	Statements in Euclidean geometry that appear to be true but aren't This answer to that question seems directly relevant to me.

Sep 22	comment	Heat Equation & Fundamental Theorem of Calculus Note that the whole expression on the left of (1) has two free variables (and none of them is $x$).
Sep 22	comment	Can I keep adding more dimensions to complex numbers? Well, it does break the total ordering property: Unlike for real numbers, there's no total ordering of the complex numbers which is compatible with its algebraic structure.
