I like philosophy. I like pie. I like it when the two are combined: a philosophic pie: that's a hard idea to fathom.

comment Does $\int_{-1}^1 \frac 1 x dx$ equal zero?
Why is $\infty - \infty$ undefined? Assuming that they're both, for example, $\aleph_1$, then they should be in one-to-one correspondence, right?

comment Does $\int_{-1}^1 \frac 1 x dx$ equal zero?
@ChrisEagle, I was unaware that there were multiple types of integral. Given that, I mean the first type of integral that one would learn in an AP BC Calculus class :)

Is there a way to parametrize it so that it would be zero?

comment Continuity of composite function
Can't you just re-write it as a piecewise function, and show continuity from that?

comment Can an irrational number have a finite number of a certain digit?
But is it possible to prove whether or not an arbitrary irrational number has a fixed number of a certain digit?

comment Using Gödel Numbering to Represent Sets of Real Numbers
To encode a single real, as long as we can describe it with letters or symbols, can't we assign each one of those a natural number, and then we have a set of natural numbers representing an irrational number. I suppose the bigger question is: are there irrational numbers that we can't define?
