Number Theory - Prime Number

Lately out of sudden I find myself fascinating about mathematic. Mathematic always been my favourite subject, to name a few number theory, mainly Prime number, calculus, trigonometry.

I guess everybody knows what is prime number, a number that has exactly two distinct natural number divisors: 1 and itself. 2, 3, 5, 7, 11, 13, 17… you might wonder why 1 is not a prime number, coz the condition say TWO distinct natural number divisor. 1 only have 1 natural number divisor mah….so cannot lor, 4 also cannot, coz have more than two distinct natural number divisor, 1, 2 and 4…so cannot lor.. the rest of the number you all sendiri add in lah ar..

Many mathematician crazy about Prime Number, and trying to find a general formula in order to get Prime Number, but there is no formula for primes. Many theorem being develop, and those beyond my and perhaps your comprehension (except Suffian Steve, btw, he is master in prime number).

Now I’m trying to figure out what’s different between Prime and Chen Prime.

A prime number p is called a Chen prime if p + 2 is either a prime or a product of two primes. The even number 2p + 2 therefore satisfies Chen's theorem (quote from Wikipedia).
There are few branches of Prime number, Chen prime, Sexy prime (no this is not typo), twin primes, cousin prime, optimus prime; haha…no no, optimus prime got nothing to do with prime number. hhehehe….

So what the hell we got to do with prime number leh? Its widely use in public key cryptography, and what the hell is public key cryptography leh? It has got to do with internet security thingy….very chim 1….but we got 1 expert among us on this…he damn kao kao punya expert lor.

Ok lah…I’m going to crack my head on this… who wanna join me cracking head? come! come! come!
