The number X is, compared to π, a relative newcomer on the mathematics scene. The first approximation to X was found by Jacob Bernoulli, who while looking at the problem of compound interest found that the number must lie between 2 and 3.
The notation that we use for the number today was given by a great mathematician, who some claim derived the notation from the first letter of his name. Others say that the claim is ridiculous. The mathematician is also responsible for a lot of other notation we use.
In its IPO filing in 2004, Google announced its intention to raise X billion dollars, rounded to the nearest dollar.
On 2010 February 21 we knew 500,000,000,000 digits of X.
What number is X? Who is the mathematician?

e. The mathematician is Euler.
e?
oh and the mathematician would be Euler?
e (Euler's logarithm base)
e and Euler
The number is 'e', the mathematician is Euler.
The number is exponential (2.71) and the mathematician Euler (?)
The number "e", possibly named after Euclid or Euler.
The answer is e and Euler, as all of you said.
