Have you ever wondered with which mathematical formula is it possible to describe a cup of coffee getting colder?
In this article you will get to know the great mathematician Euler and his mathematical invention about the e-number, which is about 2,71828... There are up to five billion decimal, it is a transcendet numder. It is the basis of the natural Logarithm (ln)....
The "founder" of this number was mathematician an physicist Leonhard Euler, a lad born in 1707 and died 1783. He firstly was self-taught and then was teached by Johann Bernoulli. After some time he was bored of studying theology and started studying maths instead. He then became a physics professor at the Petersburger Academy of Sciences. He wrote many interesting books like "Mechanica" but you can read all about it at Wiki.
That's a bit boring right? Well, you have to just check out how we can calculate it by the steady interest.
