What about finger prints. With over 7 billion people alive to day and counting that's over 70 billion prints.

Its estimated that around 90 to 110 billion humans have ever lived, thats 1000 + Billion prints never repeated and on going. see here

Don't identical twins have the same prints, or isn't there such a thing as truly identical twins?

"The progression of hydration can, though, be predicted using mathematics."

It can be predicted for a given set of circumstances,but predictions cannot accurately take account of random variables, such as ambient temperature changes, water content in the mix, the origin of the Portland cement (its constituents vary from country to country), and the salts present in the sand.

Such calculations might be done, but they would by necessity be incredibly complex and would fill several large books. It's why the construction industry uses a rule of thumb 28 day period for maximum load-bearing strength to develop.

We're dancing on the head of a pin here, and of course in theory you're right - mathematics can do the job. I've had my fill of this however, and like you and others I'm calling it a day.

Quickbeam from what I read even twins have different finger prints.

Its there DNA thats difficult to tell apart, and its thought that its around one in 5 billion that DNA could be replicated in our make up.
