Who Discovered Earth?

Who Discovered Earth?
Discussing who discovered earth may take the topic back to the Garden of Eden. This was where man was said to first discover his planet. However, discovering earth can mean a lot of things to a lot of people. Who Discovered Earth was Not the Center of the Universe? Discussing who discovered the planet may be in terms of who did so to prove that it was not the center of the universe. In ancient times, earth was thought to be located in the center of the universe. All other planets, including the sun and stars, revolved around it. It was among the central teachings of the church. To believe otherwise was considered heretic. Nicolaus Copernicus was the man who discovered earth as merely among planets that revolved around the sun.

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...

Who Discovered Heart Disease?

Who Discovered Heart Disease?
In ancient times, most civilizations dealt with diseases and medical problems with the use of magic or occult practices. However, there were early records that Egypt treated diseases with basic medical know-how. And an Egyptian could well be the first person who discovered heart disease and provided some medical remedy. Ebers Papyrus Georg Ebers was not who discovered heart disease. However, he discovered a 110-page or 20-meter long scroll in hieratic Egyptian inscription around 1873 to 1874 in Thebes. It was a record of medical data made and kept by ancient Egyptians in 1550 B.C. Among its contents was how to detect heart failure. The Ebers Papyrus reflects a comprehensive Egyptian knowledge of the basics of heart failures and diseases and simple measure on how to treat them. With this fact, it would be safe to assume that the first heart doctor was an Egyptian. Some Early Clinical Heart Diagnoses The Ebers Papyrus described several clinical heart diagnoses made by the early Egyptians,...

Who Discovered Medicine?

Who Discovered Medicine?
Introduction Medicine is universal to all mankind. It may even be found amongst animals. For example tigers and dogs eat grass when they have digestive problems. Because sickness is common to all, it is impossible to say that one person discovered medicine. Here we give a brief history of medicine in the ancient world. Oldest Discoveries in Medicine Like animals, primitive man used plants as medicine. Animals seem to know what is good for them when they are ill. It may be inherited or instinctive knowledge, or a little bit of both. With prehistoric man it was probably the same thing. Over time with much experimentation, people came to know more and more about the helpful plants around them. These herbs, fruits and vegetables were therefore the first medicine humans discovered. Discovery of Medicine in Egypt Herodotus in his Histories praised the ancient Egyptians as “the healthiest of people,” second only to Libyans. He ascribed this to good weather conditions and a sound health care...
