Prime number

I was watching the Brain Man presentation in the last few weeks. Daniel is exceptionally genius but had to undergo tests yet to prove that he has superpower brain capable of performing very complicated numbers and a memory that is almost limitless it’s amazing to see the extent of the capacity of the human brain. Some people who did not know or meet him were skeptical at first, and only their own tests can get rid of their doubts. Who know someone was just pretending; but when you get to know Daniel, he is such a gifted good man who is true to himself and never takes advantage of what mental wealth he has, nor hide that gift. For if other were skeptical, some also were wanting to go ahead of him. One of his tests was to determine prime numbers from a given random list. It was not surprising though but amazingly he was able to determine which numbers are prime and which are not in a given second, among any other challenges deemed impossible for ordinary humans.

The 27 y.o. has a blog called Optimnem Blog: – The Blog of Daniel Tammet A blog of a high-functioning autistic savant. Another great read is found here.

What are prime numbers, and who cares what they are?

In mathematics, a prime number (or a prime) is a natural number greater than 1 which has exactly two distinct natural number divisors: 1 and itself. In the 1970s it was disseminated that prime numbers could be used as the basis for the creation of public key cryptography algorithms, also used for hash tables (computer science) and pseudorandom number generators. In cryptography, the use of prime numbers are for public key encryption that ensures confidentiality by encrypting messages with a public key and a corresponding private key for which only the recipient suppose to possess; and also for digital signatures to ensure authenticity.
