I think running two arguments at the same time is going to get difficult, so I will promise to come back to this Chicago thing in a bit but lets keep looking at this bath of yours, as that is your major proof against a globe, yet is somehow acceptable on your curved earth because you say your curve is minor.Short distances?
I've never went over 50 miles so don't bother using that argument.
And you can't help jumping in that bath, can you.
Your figure is wrong because the bath water is level, so you have no figures to use.
You're going on the assumption that water curves at rest. It does not.
You really need to try and get out of the 50 mile, 1666 feet drop of your globe and the saying that buildings can clearly be seen in Chicago from lake Michigan as we're told by the news channels. Unless they're telling lies on this and you really can't see it.
What do you think?
The maths is absolutely not needed for a bath. You are welcome to argue that bath water curves if you want to and are welcome to give minute figures if you want to.
However, we are dealing with miles of water and the drop which you clearly understand would be the case on a globe of the size that's made out.
Trying to argue it goes skewed over long distances of over 100 miles is neither here nor there when we are dealing with 50 miles.
But I don't see why you refuse to calculate what the curve of the globe of accepted size would be over the length of a bath. Lets go with your rule, it is within +-1% accuracy, so I'm happy to go with that.
The globe model is that a surface of water will conform to the shape of the earth, showing it's curve. You say that 1/1000 of a millimetre is not correct. What would you expect it to be? More than 5cm or less than 5cm?
