Topologically, it is a sphere with handles. And every time a new clover-leaf highway interchange is built, we add more handles. There are also natural handles (natural bridges, caves with multiple openings). Geometrically, it is not a sphere -- there are too many hills and valleys for that. Those are all fairly minor deviations from a sphere. Far more significant is that the earth is actually bulges out into something like an oblate spheroid due to gravity and spin. The equator bulges out at about 26.5 miles which is far larger than any hill or ocean trench. Geodesy and the Earth's Size and Shape

So get yourself on the dock and set up a sufficiently powered light source (a common laser will do). Put yourself on a boat with a target and note where on the target the laser hits. Then, simply putt on out into the lake, paying attention to where the laser hits the target. Be careful with this experiment. After reading a post by Dr. Adequate on the subject, I looked up the details of the experiment and found that it was possible to get a flat earth answer if atmospheric refraction kicks in. Such problems can be aggravated by a temperature inversion. You can avoid this by setting up your sight line a few meters above the surface of the lake.

As long as gravity is orthogonal to the surface, I don't think it makes any difference whether the surface is flat or convex - gravity will pull the bullet toward the surface. To fit the physics, a flat earth would need "lines of gravity" that were parallel instead of convergent at the center of mass. Gravity is orthogonal to a finite surface only when the surface is spherical. Also, gravity is not directed towards the center of mass for shapes that are not roughly spherical. See Gauss law for the details. Under a government which imprisons any unjustly, the true place for a just man is also in prison.

Assuming no air resistance, the drop time would be closer to 1 1/2 seconds (sqrt of 2). You're mixing up the downward speed and the downward acceleration. More to the point. He is making silly ridiculous errors in computation while complaining about an approximation by Galileo. His own answer is about 40% too low. By the way, heavy "objects hit the ground first due to air resistance" requires a lot of qualifiers. Example, what hits the ground first, a three pound package of nearly folded cotton shirts or a one pound steel ball? Or a man with an opened heavy parachute versus a man with no chute? Or a fat man versus a lighter, skinny man? Edited by NoNukes, : No reason given. Under a government which imprisons any unjustly, the true place for a just man is also in prison.

Can a fat man actually fall slower by presenting a bigger surface area? Yes, he can. In fact, a skinny man can alter his terminal velocity considerably by reorienting himself.

Indeed it does, which is why I said "cannon balls'. Same density, same shape, different sizes. Not correct. You have not consistently limited your statement to cannon balls. Here is your initial statement on the subject.
In a similar vein I also say Galileo was wrong in his experiment dropping weights off the leaning tower of Pisa; the heavy one should hit the ground first. Just for some background, the pre-Scientific method conclusion was that objects would fall at speeds proportional to their mass. Galileo's experiments were performed with balls rolling down ramps and were conclusive that gravity did not work this way at all. To complain about the effect of air resistance, which was the reason why the Aristotle view survived so long, is to miss the entire point of Galileo's creation of the scientific method. In short Galileo's contribution was to separate the force of gravity from other forces like air resistance. Your contribution is to be a buffoon. Edited by NoNukes, : No reason given.

Well, no wonder you don't understand a thing about what Galileo said and keep getting the physics wrong. After you quoted Galileo explicitly acknowledging the air resistance issue, there is really no honest thing for CRR to do other than admit that he was wrong about Galileo. I know exactly what to make of his refusal to do exactly that, and I would hope that everyone else does too. Something to think about when you are watching CRR make other ridiculous arguments. Is it really worthwhile to try pinning down Jello after exposing the slimy fluid that Jello is by nature?
