This is another example of how smart, so many people are, in so many different ways, for so many different reasons and quite often, they work with other ideas and or evolve into further developments, for even more diverse reasons and ideas.
Take rolling a heavy object along over logs.
These evolve into wheels and axles.
The wheels evolve into steel disk wheels, with inflatable rubber tyres.
They evolve into carbon fibre, magnesium and alumium wheels, when combined with specialist tyres that have very high loadings, or very high adhesion, or block treads, to go under bicycles, aircraft, trucks, forklifts, drag racers and all terrain vehicles.
These issues, go on around us all the time, in an almost uncountable number of ways.
@bigintol03: A bit of grattitude is a good thing.
There is a huge amount of extraordinarily smart people... and although there is so much that is available to learn, there is far too much of it, and what you can learn, is for the most part, at least being aware of it, rather than being an expert in it.
Do you know about the gravitational forces that influence the tides, the standard 2 x a day high tide and low tide, and the LUNAR king high and king low tides, when the gravitational forces add up or detract from each other.....
If you can study this subject, THEN the analog computers, and how people figured how to make the calculators that would predict the tides and the dates and the times of these various events, makes a LOT of sense, especially since ALMOST everything is and has always been moved around by ships....
Since the depth of the ships are a given, with a specific load, say it sinks 10 meters in to the water, IF the seas average depth in a specific tidal zone is say 8 meters , when the NORMAL high tide is in and the water is 10.5 meters deep, then the ship can reach the port and unload and leave, and with only being half full it only sinks 8 meters into the water... so it can exit the port while the tide is going out, until the water depth is about 8.5 meters deep.
However when the tide is right out, then the water depth drops to 6.5 meters, then the ship is either stuck in a dredged out port or it sits on the bottom, and has to wait until the next high tide.
However when the suns gravity and moons gravity combine, then the KING tide, is another meter higher and another meter lower....
When it comes to sea travel, knowing the depths of sand banks, esturies, reefs, rocks and the tidal and storm conditions is the difference between passing over them or getting stuck on them or running into them, or if the currents or currents and winds are strong enough at certain times, the ships can get washed onto the rocks etc.....
So some of these are not so basic and some have a great deal of detail..... BUT at least sort of understanding them enough, makes the entire issue of calculating tides and using the orbit of the earth around the sun, spinning on it's axis as it does AND the moon spinning around the earth.... It's not exactly simple, but the complex issue, is made of simple things.
AND in the days before radio and satellites etc., people HAD to carry books and charts of all the tidal tables and navigational charts, for their ships and the charts had to be as accurate as they could be.

That was fascinating, thanks for posting Shane,I've never been a tech guy but I followed along as best as I could!
