Who Discovered Mercury?

Who Discovered Mercury?
Mercury, be it the element or the planet, is quite elusive when it comes to its discoverer. But at least, as far as who discovered mercury the element is concerned, there’s a name worth mentioning. The First Unnamed Discoverers The Babylonians, among the first people groups of early civilization, is credited to be the first to put on record the use of the element mercury. This was some 3000 years ago when it was mixed freely with other products. It was then sometimes added in creams and ointments in dangerous proportions because it was not yet known then as a chemical element. At times poisoning was the result. The discovery of mercury as an element was in the 18th century. Incidentally, at about the same time, also 3000 years ago, the Sumerians discovered the planet Mercury. Like the Babylonians who discovered mercury and put in many records but not as an element, the Sumerians recorded the planet mercury quite a lot. It could be said that both element and planet had probably...

Who Discovered Fireworks?

Who Discovered Fireworks?
Who discovered fireworks? The Chinese discovered fireworks and gunpowder about two millennia ago during the Sung Dynasty. A popular story tells how a cook stumbled upon it when he unintentionally mixed sulphur, saltpeter and charcoal. The mixture was combustible: it burned and when stored in a bamboo case exploded. This may be considered the first fireworks ever made. But not for the same purpose as fireworks are now used—in celebrations. The Chinese had a more urgent issue to deal with. They built rockets powered with this new powder and used them well against the Mongols in the 1200s. A thousand years later, another Chinese man discovered he could make firecrackers. This time it was a Chinese monk from the city of Liu Yung, in Hu Nan province. The monk’s name was Li Tian. His achievement was so significant to the Chinese that they built a temple for him during the Song Dynasty. Since then, the Chinese have been celebrating the discovery of fireworks on April 18 by making offerings...

Who Discovered Copper?

Who Discovered Copper?
Introduction Who discovered copper? Nobody knows. But evidence suggests that copper was the first metal ever discovered and used by man. Or at least one of the oldest. In modern day Iraq, archeologists once found a copper pendant over 10,000 years old. Unlike silver, copper is often found uncompounded in its natural state. So it is likely that humans learned to use copper first, perhaps along with gold and meteoritic iron. History of Copper Two of the world’s oldest civilizations made use of copper – Chaldea and Sumer. They used copper to make military equipment such as bows, arrows, spear heads and helmets. Archeologists have also unearthed small items like copper pins, harpoons blades and pots made of bronze (a copper alloy). Sumerian craftsmen made beautiful sculptures made from copper and mounted them on walls. The Imdugud Relief is a fine example of this. It dates from 3,100BC and shows an eagle with the head of a lion, holding a stag in each claw. Copper can be mixed with other...
