I studied Applied Mathematics and Physics.
So have I. And, sadly, nothing in those math and physics classes was related to the shape of the earth.
What do you know that discredits hundreds of years of scientific research, that has been proven thousands of times over?
Round Earth theory has not been proven even once, let alone "thousands of times." Before making such statements, perhaps you should link us to some experimental evidence which conclusively proves Round Earth Theory. I believe you already know where to go for our experiments.
Plus I have flown over part of Antarctica and guess what, it wasn't an icewall.
The coast of Antarctica is the ice wall.
Modern science has an explanation for sunrise, sunset, eclipses, seasons, orbits, constellations (and their movement through the sky,) general relativity, the nature of mass, the mass of the earth, the formation of galaxies, stars and planets (AND their satellites) the radius of the earth, the nature of the atom, space travel... all of these are simply explained with a round earth.
Flat Earth Theory has super-refraction of light, gravity defying orbits,
a mysterious shadow object that somehow is only visible during eclipses and is otherwise undetectable, no explanation as to the nature of mass and how the earth formed, optical illusions, an Icewall around the entire earth that apparently nobody is aware of, and a GLOBAL conspiracy in a world that has been consumed by war for thousands of years.
In short. You do not need to do any single experiment to "prove" round earth theory.
You repeatedly state, "my observations indicate that the earth is flat."
I say to you know, "hundreds of years of tried and tested science, that is repeatedly improved and build upon indicate that the earth is round."
Unless every physics and mathematics paper written since, hmmm, probably ancient Greek and Chinese civilizations times, is proved to be wrong, then your theory is nothing but pure spin, speculation, and pseudo-science. It's enjoyable, light-hearted and fun, but it's simply not true. If you can prove and discredit Newton, Euler, Einstein, Pascal, Hawking (I know I'm name-dropping here, sorry) and every other prominent mathematician, physicist, and chemist for the last few thousand years, I'm never going to believe your theory.
So, you've got a lot of work to do.
P.S - There was no wall at Antarctica. The aircraft flew in on one coast, crossed some land, and flew out on another coast. Maybe you should go on an expedition there, if you're so convinced. Walk around the entire peninsula and arrive back at the start - If you've walked around every continent on Earth, your theory will be proved. Plus, it's already been shown that GPS can work on a flat earth - you'll know exactly where you are every step of the way.
