Euler didn't discover calculus. He made major contributions to calculus throughout his career, but the foundations of calculus were put forth by Newton and Leibniz.
Euler's numberThe mathematical constant 'e' (base of the natural logarithm) was discovered by Leonhard Euler. Which explains why the number 'e' is sometimes referred to as Euler's number (not Euler's constant, which is a completely different thing).Euler did not discover e although many believe he did. Roger Cotes discovered e.
The first references to e were made in 1618 in a work by John Napier - though it was not, at the time, called e. Leonhard Euler began to use the letter e for the constant in 1727, and its first use in publications came in 1736, in Euler's Mechanica.
i think Archimedes was the first to discover pi (3.14) or leonhard euler by brichelle xD

Euler first noticed that special lines, already well known, that cross at special points within the triangle, like the midian and angle bisector lines, that a new line can be drawn through all those special points. Im not sure when he discoverd it but this video about his life is where I seen this: http://www.youtube.com/watch?v=h-DV26x6n_Q
The difference between an Euler circuit and an Euler path is in the execution of the process. The Euler path will begin and end at varied vertices while the Euler circuit uses all the edges of the graph at once.
Lucie Euler's birth name is Lucie Luise Euler.

He discovered the relation between faces, vertices and edges. (I don't know what this relation is, I am trying to find out myself!) This is known as the Euler characteristics. For convex polyhedra, the numbers of vertices (V), edges (E) and faces (F) satisfy the following: V - E + F = 2 For more general conditions follow the link for the Euler Characteristic, below: http://en.wikipedia.org/wiki/Euler_characteristic
