Primality test - Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Primality_test
From Wikipedia, the free encyclopedia. For determining whether an input number is prime. Amongst other fields of mathematics. It is used for cryptography. Primality tests do not generally give prime factors. Only stating whether the input number is prime or not. Factorization is thought to be a computationally difficult problem, whereas primality testing is comparatively easy (its running time. In the size of the input). Some primality tests prove. That a number is prime, while others like Miller Rabin.

Online test for prime numbers. Let's go back to ancient times and read the definition Greeks had for these numbers: A prime number is that which is measured by a unit alone. (Euclid,. Book 7, definition 11.). Not having that many divisors is something that can be expected for the smallest numbers; however, prime numbers don't cease to exist and turns out that they keep being as recurrent as they are in the first one hundred digits.

Here are two clock puzzles invented by Lewis Carroll:. 1) A clock has hour and minute hands of the same length and no numerals on its face. At what time between 6 and 7 o'clock will the time on the clock appear to be the same as the time read on the reflection of the clock in a mirror? 1) 360/13 minutes after 6. Friday, January 28, 2011.

http://ziolenigmes.blogspot.com/2011/03/23-la-constant-auria-amb-una-mentida.html
Els enigmes d’en Ziol. Trencaclosques, més o menys fàcils, i també subtils, per fer gimnàstica mental. Diumenge, 20 de març de 2011. 23: La constant àuria amb una mentida. La constant àuria, anomenada també divina proporció, és la relació que guarden dues quantitats x. Si entre la seva suma i la més gran d’elles hi ha la mateixa relació que entre la gran i la petita. El seu valor numèric amb quinze decimals és: 1,618033988749895… s’acostuma a representar amb la lletra grega fi, ( φ. Sinó que és la millor...
