Today we can easily find out the circumference of our planet by simply “Googling” it online. There are some, however — the Flat Earth Society to be exact — who argue that the Earth is in fact not a sphere, but a flat plane.
Long before the NASA was sending satellites up into space, the ancient Greeks developed a way to determine the world was spherical over 2000 years ago. In fact, Greek mathematician Eratosthenes (276 BC to 194 BC) had it all figured without using any modern equipment.
Eratosthenes, way ahead of his time, discovered that no vertical shadow is cast at noon on the summer solstice at the Egyptian city of Syene (now Aswan). This happened because the Sun was directly overhead.
Upon returning to his city Alexandria, the mathematician tried to prove if the same thing happened there. He stuck a stick in the ground to see if, at noon, it generated shadows or not. And of course, there was a shadow, and it measured around seven degrees.
Eratosthenes’ simple and extremely low budget technique confirmed the speculation that the Earth is round. If it was not curved or round, he should not have seen any shadows in Alexandria, as it happened during his visit to Aswan.
The concept of a “spherical Earth” was theorized by Greek philosopher Pythagoras around 500 BC and later validated by the great philosopher Aristotle a few centuries later.
If the Earth was a sphere, Eratosthenes, also the head of the library in Alexandria, could use his observations to measure the planet’s circumference.
So without any fancy technology or huge government funding, a man from Ancient Greece discovered the circumference of our planet – and all he required was his brain and a stick.
As for the Flat Earth Society, Eratosthenes must not be so popular among them.

Actually, Hawaiian Pizza Was Invented By A Greek Businessman – In Canada!
Does pineapple belong to pizza? We have this man to thank (or blame)!
Perhaps no other topic is as divisive among pizza lovers as this: does pineapple belong to pizza or not? It's a question that's sure to prompt a long debate when asked in a crowd because really, people have strong opinions about it. In most cases, its either they absolutely love it or furiously hate it. There is no middle ground.
In fact, some may even remember that President Guðni Th. Jóhannesson of Iceland even suggested once that he wants to ban pineapple on pizza. Canadian Prime Minister Justin Trudeau wasted no time and responded to this on Twitter saying, “I have a pineapple. I have a pizza. And I stand behind this delicious Southwestern Ontario creation.”

Here’s Why One Man Destroyed One Of The Ancient Wonders Of The World
If you think you’re petty, you’ve obviously never heard about Herostratus.
Most of us can be petty at times but one man took it to a whole new level. He destroyed one of the Ancient Wonders of the World just so everyone will remember his name. Interestingly, not a lot of people have actually heard of him.
The Temple of Artemis was a Greek temple located in Ephesus dedicated to the goddess of the hunt and chastity. It was one of the Seven Wonders of the Ancient World alongside the Great Pyramid of Giza and the Colossus of Rhodes. Although it was rebuilt three times during its existence, it was the shocking actions of one man that enraged ancient worshippers.
The temple's first incarnation was destroyed by a flood but it was the second destruction that enraged the Ephesians.
