where P and T are the pressure and temperature of air, and P0 and T0 are the standard values of one atmosphere of pressure and 300K. Since with mirages there is no appreciable height difference, pressure differences are negligible, and so the temperature difference dominates differences in the index of refraction. When light travels from one medium to another, the path of the light is refracted, or bent. This is what causes the “bent stick” appearance of a long object partially inserted in water, such as a pole placed into the water of a pool. This behavior is described by Snell’s law:
40) From near Cape Horn, Chile to Port Philip in Melbourne, Australia the distance is 10,500 miles, or 143 degrees of longitude away. Factoring in the remaining degrees to 360 makes for a total distance of 26,430 miles around this particular latitude, which is over 1500 miles wider than Earth is supposed to be at the equator, and many more thousands of miles wider than it is supposed to be at such Southern latitudes.
I have been an advocate for the flat earth for months thanks to your research. I have been debating my family and even got grounded by my parents a couple times when i lost my patience (I was still in high school at the time). I have weakened relationships and even lost friends all together because of my need to show those around me the truth. I completely believe the earth is flat and want to spread the message as much as possible. I have downloaded and printed multiple copies of your 200 proof book and dispersed them to my friends and even their parents. I am letting you know this because i was banned from The International Flat Earth Research Society i believe twice now. I either created a thread when i shouldn't have or an admin took me as a shill. I even messaged you a couple months ago about an introduction, math proof, and index i made to supplement your 200 proof book. This all being said i can not allow myself to be banned from the forum as i need to learn more. Please do not ignore this message and help me someway be able to access the forum again.

22.) God's Truth never – no, never – requires a falsehood to help it along. Mr. Proctor, in his " Lessons," says: Men " have been able to go round and round the Earth in several directions." Now, in this case, the word " several will imply more than two, unquestionably: whereas, it is utterly impossible to circumnavigate the Earth in any other than an easterly or a westerly direction; and the fact is perfectly consistent and clear in its relation to Earth as a Plane.. Now, since astronomers would not be so foolish as to damage a good cause by misrepresentation, it is presumptive evidence that their cause is a bad one, and – a proof that Earth is not a globe.
25.) The surveyor's plans in relation to the laying of the first Atlantic Telegraph cable, show that in 1665 miles – from Valentia, Ireland, to St . John's, Newfoundland – the surface of the Atlantic Ocean is a LEVEL surface – not the astronomers' "level," either! The authoritative drawings, published at the time, are a standing evidence of the fact, and form a practical proof that Earth is not a globe.
