- Horror for every student, no, not for everyone.
I liked it in spite of not-motivated teachers(today I know other math-teachers)
so much that I studied Mathematics at University.
One of my favorite themes in Mathematics is the unsolved twin-prime-problem.
Prime-numbers are natural numbers(1,2,3,4,...), wich you only can divide through 1
and through the number itself.
Twin-primes are two primes with the distance 2 (11-13, 17-19).
In school you already learn that there are an infinite number of primes. But until
today there is no prove that there is an infinite number of twin-primes.
Who is interested will find
a website about it.
you find a German website about prime-twins. Much fun!!!
The greatest primenumber found yet (12/26/2017) is:
277.232.917-1 a number
with 23.249.425 digits. This kind of primenumbers are called Mersenne-Primes.
This is the 50th and was verified by Jonathan Pace from Germantown in Tennessee, USA.
