Cortez went looking. I don't believe it's been found.

I believe yes. Today we read studies of ancient scientists like Demokritos who spoke about energy, space and physics or like the greek doctor Ippocrates and we find out that the were right in the most of what they were saying. Is really amazing that they  were so beyond their age!\nIs really worth to find and study their work.

The sphericity of the earth was known long before Eratosthenes, but he did measure the size of the earth. \n\nEratosthenes had heard tales from travellers that at noon on midsummer's day in Aswan, Egypt, one could see the image of the Sun on the water at the bottom of a deep well. He realized that this could only happen if the Sun was directly vertical on that day at Aswan. He then measured the angle of the Sun from vertical at his home in Alexandria at noon on midsummer's day, and determined (using a compass) that the angle was 1/51 of a full circle. Since he also knew that the distance from Aswan to Alexandria was 5000 stadia (about 500 miles), he computed the circumfrence of the Earth to be 51 * 5000 or 255,000 stadia. This is a remarkably accurate result.

matahari is right, it was Aristarchus of Samos. But his ideas were not accepted and his writings were lost. We only know about him from the writings of Ptolemy, who did not believe in heliocentrism himself. The idea was later reinvented by Copernicus, whose writings were preserved and his ideas eventually accepted.

Johann Wolfgang!\n\nHe discovered furfural, worked on the use of platinum as a catalyst, and invented a lighter, known as Döbereiner's Lamp.\n\n:)

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who developed many devices which greatly influenced life in the 20th century. Dubbed "The Wizard of Menlo Park" by a newspaper reporter, he was one of the first inventors to apply the principles of mass production to the process of invention, and can therefore be credited with the creation of the first industrial research laboratory. Some of the inventions credited to him were not completely original, but alterations of earlier patents (most famously the light bulb), or were actually the work of his numerous employees. Nevertheless, Edison is considered one of the most prolific inventors in history, holding 1,097 U.S. patents in his name, as well as many patents in the United Kingdom, France, and Germany.

Yep it's water but not the fountain of youth. Drinking water and lots of it rejuvenates the skin and keeps it healthy and nourished, our bodies and the earth is made mostly of water so go figure.  We can't survive without water you would die, literally.

You have to start with Anton van Leeuwenhoek. This Dutchman was the first man to use a microscope to view water and saw the small animals living there. He is called the father of microbiology according to wikipedia.

Archimedes was the first scientist to test their theories through practical experiments. His most famous discovery was buoyancy through the bathtub experiment. After its discovery, he is believed to have run naked through the streets of Syracuse shouting Eureka or I have found it. He was also responsible for a number of inventions such as Archimedes screw.

His name was Alessandro Volta.  Alessandro Volta discovered the first practical method of generating electricity.  In 1800, he arranged zinc and copper discs in a column and invented the battery.  His most famous invention was the voltic pile. \n\nThese links should give you all the good stuff!

Some 3,000 years ago, the descendant of Aeneas, Brutus got the advice and direction by the Oracle of Artemis of Melita (Malta) to make the New Troy. Following the directions, he founded the city which is now known as London! The island took His name: Brutus -> Bruttania -> Britannia -> Britain!

Carl Wilhelm Scheele discovered it in 1772, and Joseph Priestly found it in 1774 (independently).  Scheele was a Swede, Priestly was an Englishman.

OK, you discovered that did you? The next step is for you to notice that the pyramids along the Nile are laid out to mimic the shape of the constellation Orion. I'll wait, go Google that to check. \n\nWhen you are convinced of that, then you must have two more bits of information. Your brain ready for this? \n\nLife on the Nile depended upon the annual flooding to bring life-giving water to the fields. No flooding, not much crops, starvation. Remember Pharaoh's dreams about the fat cows and the lean cows? Right. \n\nPriests need to be able to predict things for their people. It gives people reasons to support their priests. There really are not much as what you can call seasons so near the equator. One thing did show when the flood SHOULD be coming (in otherwords, when it would be raining down south in the mountains of the headwaters of the Nile) and that was when the constellation of Orion, or more properly, the brightest star in the sky (besides the sun) Sirius would rise just a few moments before the sun - the helical rising of Sirius.\n\nThere is a shaft, often called an "air shaft" that goes down the Great Pyramid at Giza, very strictly aligned. When astronomers were able to do computer modeling to take into consideration the procession of the equinoxes and the apparent wobble of the earth on its axis, they were astonished to find out that this air shaft aligned to when Sirius would rise with the Sun. \n\nSirius, as you probably have seen used as the logo for Sirius satellite radio, is called "The Dog Star." \n\nHow does that all go together? And why am I telling you this? One more thing and I will let you go look some more.\n\nLook up the Dogon people of Africa. Remember now that Egypt is on the African continent. They have a story of how they got here (earth). They claim they got here on ships with Gods from another place. That place is Sirius. The gods, they say, had fish tails - looks a lot like the great God Dagon over in the Middle East, Philistines worshipped Him - and at least one of the gods died on the journey. \n\nBut god and dog are English words. None of this is real. This is all just fancy word-play made up to confuse you. Nobody believes this. This is not a story my people tell; this is just something I tell you who read this right now. \n\nDrab as a fool, aloof as a bard!
