jvandyke_texas 432 Posted February 28, 2019 Share Posted February 28, 2019 He gets some of it right. I was in Honors physics class in my first year, and one assignment was to mathematically describe the tides. I got the right answers at selected points, but not the overall function. Function was 3rd order and had an R^3 in it. The way to find the solution is as he says, to treat earth as totally covered in water. Then you assume if there is a change in gravitational potential, water will flow. So the whole earth has an equipotential surface. Calculate that, and you have the tides. I think it was about a meter. The reason why Bay of Fundy in Nova Scotia has such high tides is because there's a body of water that has a resonant frequency equal to the tidal period. Water sloshes in and out with a period of 12 hours. 1 Link to comment Share on other sites More sharing options...

Yes, I'm not sure why he didn't explore that; perhaps he didn't want to obfuscate the main topic Link to comment Share on other sites More sharing options...
