The Natural Logarithmic Base It is not known who first determined We see in this limit the outcome of a fierce tug-of-war. On one side, the exponent explodes to infinity. On the other side, 1+x rushes toward the multiplicative identity 1. It's interesting that the additive equivalent of the above limit is trivial. A geometric characterization of e is as follows: e is the unique positive root x ...

Brun's Constant Brun's constant is defined to be the sum of the reciprocals of all twin primes: Note that the prime 5 is taken twice (some authors don't do this). If this series was divergent, then a proof of the Twin Prime Conjecture would follow immediately. Brun proved, however, that the series is convergent and thus B is finite .

The Golden Ratio and The Fibonacci Numbers The Golden Ratio ( ) is an irrational number with several curious properties. It can be defined as that number which is equal to its own reciprocal plus one: = 1/ + 1.
