youtube for the day/James Burke Connections episode five:

I include this one if you want to see some more buy different view of much of yesterday's James Burke's Connections episode 4.  Likewise, I give James Burke Connections episode five because episode four and five are related.

I've argued that despite Mr Burke's best efforts to suggest that everything is non-linear; there is a basic pattern - the essential influence of mathematics on all human endeavors.  If you get to the underlying nature of mathematics, well, I've shown that you can see that follow the understanding of mathematics, and you can see the connections.  James Burke's "Connections" and "the Day the Universe Changed" try to keep things messy(curiously, James Burke later tries to see ways of organizing everything by some one principle - like in "After the Warming" where he sees everything from the point of view of global warming or cooling - or in The Axemakers gift where he tries to show everything coming from the axemakes axe); yet, I can show that if you understand aspects of mathematics, you can organize his connections.  Like here in episodes four and five of his connections(his first connections video and book), there's the same influence of greek geometry on mechanical engineering.  In episode four, Greek mathematics eventually allowed the Romans to build the Barbegal aqueduct(to late in roman history to save the Romans).  Here, in episode five, we see the affects of the knowledge of Greek geometry and astronomy to build clocks.
-I think I'll save a big point for later.
