It took him a year and a half, but Veneziano finally realized this: all the mathematical properties of the S‑matrix he sought were possessed by a single, simple mathematical function called the Euler betafunction.

ZIMMER: Yeah, this is  you saw  sometimes called Euler's identity.

"We'd also like to celebrate Feb. 71 ... but that won't work," joked Kotula, referring to another important transcendental number in mathematics, 2.71, known as Euler's number.

The great eighteenth  and nineteenthcentury mathematicians such as Euler, Laplace, Lagrange, Hamilton, and
ruzuzu commented on the word Euler
"Euler's work touched upon so many fields that he is often the earliest written reference on a given matter. In an effort to avoid naming everything after Euler, some discoveries and theorems are attributed to the first person to have proved them after Euler."
