OT: Happy Birthday, Euler, born 308 years ago today.

[LionJim]

We owe to Euler the notation f[/I] (x[/I]) for a function (1734), e[/I] for the base of natural logs (1727), i[/I] for the square root of -1 (1777), π for pi, ∑ for summation (1755), the notation for finite differences Δy[/I] and Δ2y[/I] and many others.

A remarkable genius.

I love this.

Euler Formula

A mathematical joke asks, "How many mathematicians does it take to change a light bulb?" and answers "

" (which,
of course, equals 1).

Leonardo da Vinci birthday, too***

Euler and Gauss are 2 of my favorite and 2 of the greatest mathematicians of all time. Throw in Newton and Archimedes too.

His most famous formula, the Euler "G" is often heard at funerals.***

The Euler Identity still freaks me out

I'll never get my head around it

Perhaps if you think of it like this.

Look, Euler's birthday is still a hot topic.
