In the branch of mathematics known as set theory, the aleph numbers are a sequence of numbers used to represent the cardinality (or size) of infinite sets. They are named after the symbol used to denote them, the Hebrew letter aleph.The aleph numbers differ from the infinity (∞) commonly found in algebra and calculus. Alephs measure the sizes of sets; infinity, on the other hand, is commonly defined as an extreme limit of the real number line (applied to a function or sequence that "diverges to infinity" or "increases without bound"), or an extreme point of the extended real number line. While some alephs are larger than others, ∞ is just ∞.

few accountants need to use complex numbers (possibly some like to work with imaginary numbers - but that is another matter altogether)

The Master on Doctor Who went nuts looking into the time vortex.

Doc you can learn a lot from fiction. All I meant is that if you try too hard to comprehend something incomprehensible you may go mad or run away from the thought by busying yourself as much as you can. Back to the astronauts, you should read Moondust. It tells how the Apollo guys either thought they heard music when looking into infinity or thought they felt God or were stupidly happy or felt very alone and vulnerable. When they returned to earth some had breakdowns, some found religion, one founded an institute to explore the unexplained and the rest worked themselves to death. Sean Bean has spent the rest of his life trying to paint how he felt on the edge of infinity.When I was young I had a story book that had a picture of a mouse and a rabbit reading the book and on the back of their book was a mouse and a rabbit reading a book and so on and so on until the print became too tiny. It was the first thing that really freaked me out. I didn't know then that this was infinity but it really messed with my head.

I guess achieving your dream in your 20's doesn't exactly leave you with any more things to conquer. Going to the moon must be hard to top. I still think that seeing the earth from space and looking out into infinity must have a strange effect on most people.
