Eleusis was a mathematician from antiquity. Also Robert Abbott invented a card game and named it Eleusis. Published first in 1959 by Martin Gardner of Scientific American, then republished in 1963 and then finally revised in 1977 as "The New Eleusis". Today you can find it in Mathematics discussions, Computer Science programming, and I also think in some circles of Philosophy. The card game is simple and actually really boring to play with real people. What makes it fascinating to me is that programmers can make bots or automaton programs that predict the future (in a sense). Using mathematics to predict certain outcomes and with increasing precision.

I am very interested in pure math, and math for maths sake. I know (3.1415926535) 10 digits of pi by heart and I like to figure out square roots of primes with the long hand method. I think that there is a primality function that has yet to be discovered. I think that pseudo-primes and relatively prime numbers are really cool. I like cryptography and code breaking. I think that e is over-rated and that phi is great. I own a third edition of Penguins book of curious and interesting number by David Wells (you must buy this book) and a new edition as well. I know C/C++, java, pascal, perl and bits and pieces of other languages.

In that case, make it the third.

Very interesting introduction, there are many people just like you, here.

I have some tricks to help you remember 100 digits of pi if you need to (not that you do). It's just...fun.

Yes, very welcome to you, Mr-person-who-came-here-more-than-a-year-ago-and-hasn't-posted-in-ages.

Why did the vector cross the road?

It wanted to be normal.
