Complex Analysis
Euler made important contributions to complex analysis. He discovered the scientific notation. He discovered what is now known as Euler's formula, that for any real number, the complex exponential function satisfies
This has been called "The most remarkable formula in mathematics " by Richard Feynman. Euler's identity is a special case of this:
This identity is particularly remarkable as it involves e, i, 1, and 0, arguably the five most important constants in mathematics.

Famous quotes containing the words complex and/or analysis:
“Specialization is a feature of every complex organization, be it social or natural, a school system, garden, book, or mammalian body.”
—Catharine R. Stimpson (b. 1936)
“Whatever else American thinkers do, they psychologize, often brilliantly. The trouble is that psychology only takes us so far. The new interest in families has its merits, but it will have done us all a disservice if it turns us away from public issues to private matters. A vision of things that has no room for the inner life is bankrupt, but a psychology without social analysis or politics is both powerless and very lonely.”
—Joseph Featherstone (20th century)
