“100 miles is sufficient to cancel out any interplay of light rays.”
There is no distance limit on atmospheric refraction. In fact, celestial bodies, which are many times further away than any object you would be sighting on the surface of the earth, are always affected by refraction when they are near the horizon, to one degree or another. For example, when you see the sun touching the horizon at sunset, it has actually already sunk below the horizon.
Shaq is tall enough to see the curvature of the Earth.
The explanation involved three triangles. That is when, incidentally, I learned that a right triangle circumscribed by a circle always results in the hypotenuse being the circle's diameter. Used that fact all my life from working around the house to tricky engineering problems. Not a huge accomplishment. In sophomore year, just the basic tools needed to learn real math the following two years of high school.
As for the Flat Earth, or the Hollow Earth, I read the books and educated myself after my schooling was done, and real learning and understanding began.
All those helped (along with Chemistry and Physics) with the understanding of the global warming panic scam, too. University math helped, but was not essential.
That any minimally educated human adult in the 21st century still believes in a flat earth, is truly mind-boggling.
He easily explained that. All Faked. Same with images of the earth in space exploding.
Special effects have been around forever. when one has a juvenile mind, at any age, all that stuff is believable.
A false assertion.
"Some," is more accurate.
I suppose it all depends on your definition of "many."
In context, even 1% of all Christians, in my universe, would not qualify as "many." Even though it is not a small number, it is a minuscule percentage.
Don't be silly. He's not into Eastern religions, which are really weird.
Another Robert Heinlein fan?
Velcro.
Actually, the Vikings invented Velcro.
Well, I doubt anyone has ever asked him what the first derivative of "velocity" is.
Then why were we taught in grade school that Columbus was told he would sail off the edge? Come to think of it, why are grade school students today taught that the collective is good and individualism is bad, ones own behavior is somebody else’s fault and that global warming is gonna kill us all...never mind!
Schools teach a bunch of stuff that is hokum when they are not teaching pure bunk.
Nobody told Columbus that he would sail off the edge. They told him his math was wrong, the East was much further away and he would die of starvation or thirst.
Which he would have if he had not bumped into the Americas.
The experts were right, Columbus was wrong and almost dead wrong.
Almost no one thought the earth was flat in Columbus’s time.
That’s a myth of relatively recent origin. All the educated knew of Eratosthenes, Columbus had studied his writings from a map given to him by a Italian mathematician. Unfortunately it had an calculation error of about 25%. Just large enough to fit North & South America - Whoops!
Wonder how many of them fly between, say, Sydney and Buenos Aires? There are flat-earthers who believe it's impossible to fly that route non-stop, and that any such flights get conveniently cancelled.
By my calculations, the tower would have to be about a mile-and-a-quarter to be above the horizon at 100 miles away.
I think that was about what I got.
Not allowing for the Earths being round, must be the cause for Shaq missing his free throws!
