Also, solving a block by hand means that you need to calculate sha256(sha256(block of transactions + nonce)) where the hash conforms to the current difficulty... Keep in mind that all miners (combined) are currently trying 11197.84 GHashes/sec. It would take longer than the rest of your life to complete by hand.

sha256(sha256(block of transactions + nonce))
Can you explain exactly what that is,or where to go to find out.
And as far as longer then the rest of my life, I am quite aware. It is just I find knowing how to manually do it is understanding it.

You can find that information here: https://en.bitcoin.it/wiki/Block_hashing_algorithm

To understand how the current difficulty plays into generating a hash that solves a block, look at this page: https://en.bitcoin.it/wiki/Difficulty

You should probably look at this pdf also to understand the whole thing: http://www.bitcoin.org/bitcoin.pdf
