Who Discovered It

Represented by the atomic number 6 and the symbol C, carbon is an important chemical element classified as tetravalent and nonmetallic. It is one of the longest existing elements known today. The most popular allotropes of carbon are amorphous carbon, diamond and graphite. It is widely used in the petrochemical industry, specifically in producing kerosene as well as gasoline. In addition to these interesting details, it is good to learn other valuable information about this all-important element such as who discovered carbon. The Discovery of Carbon Who discovered carbon? Although this element was discovered in prehistory, several individuals contributed to a clearer knowledge about its different properties and characteristics. For instance, French scientist Rene A. F. de Reaumur first showed in 1722 that through the absorption of carbon, it was possible to transform iron into steel. By 1772, the father of modern chemistry Antoine Lavoisier discovered that diamonds were in a way one...

One of the most amazing facts about tin is its usage since ancient times. There is evidence that Stone Age men used it 3,500 years ago. How the ancients discovered it is still a mystery. Discovery and History of Tin During the Late Stone Age people learned to put tin and copper together to produce bronze. Bronze was much easier to manipulate than copper and its use became widespread. This discovery ushered in the Bronze Age, which influenced the Egyptian, Mesopotamian and Indus Valley civilizations. Everything from weapons to utilities were fashioned from these materials. One of the oldest tin mining sites is in the Taurus Mountains in Turkey. An assessment of the facts about tin will show that usage of tin as a pure metal didn’t start until 600 BC. Tin was used heavily during the Medieval Ages, with Cornwall being one of the leading producers. Tin were also discovered and used in Asia. China, Laos and Indonesia were among the countries that also utilized the element. By 1931, the International...

Introduction The Big Dipper is a group of seven stars. They are a part of the constellation known as Ursa Major. The Big Dipper is so located that it can be used as a point of reference to find other star groups. For example the North Star can be found in a straight line above starting from the two foremost stars of the ladle shape. Because the Big Dipper is clearly visible at night to the naked eye, it must have been known to mankind for as long as he has lived on earth. Discovery and Names of the Big Dipper in Ancient History No single person discovered the Big Dipper. It has been known and catalogued as a group since the earliest civilizations. Many names have been given to the Big Dipper by different peoples. In Britain the cluster of stars was seen as a Plough, Charlie and His Wagon or the Butcher’s Cleaver. In Ireland it was called the Starry Plough and was reputed to have political relevance. Scandinavians probably corrupted the name Charlie and His Wagon to Karlsvogna. Or else...

The slope formula determines the position of a line with respect to its “x” and “y” coordinates. This mathematical calculation is the concern of Analytical Geometry which solves linear and geometric problem with the aid of Algebra. Thus, to the question who discovered the slope formula, it is necessary to look into who started Analytic Geometry. Rene Descartes 1596 Rene or Renee Decartes is the father of Analytical Geometry. He was a French mathematician, physicist, philosopher, and theologian. Many mathematics experts acknowledge him as the man who discovered the slope formula. He was said to have provided a method to solve the problem of lines and slopes in mathematics by his prowess in Algebra and Geometry. The basic slope formula is y=mx+b while the more complex point-slope formula is y-yl=m(x-x1). Because Descartes is the father of Analytical Geometry and this subject centers mostly on lines and slopes, he was the first to introduce solutions to slopes and linear problems....

Do you think history can tell you who discovered the constellation Pegasus? Actually, if you look back and check the records, you wouldn’t find an actual person who discovered the constellation Pegasus. Why? Because this constellation wasn’t actually discovered years ago. Rather, it was invented. Patterns in the Sky No More Originally, the ancient Greeks see the constellations as patterns to be read and examined. But, it was learned that these so-called patterns were actually fixed areas that you can find covering the entire sky. There are about eighty eight (88) modern constellations and Pegasus is one of them. It is also included in the forty eight (48) constellations as listed and invented by the famed Greek astronomer Claudius Ptolemy during circa 150 A.D. The Naming of the Constellation Yes, it was Ptolemy who invented the Pegasus constellation. Ptolemy was known to be the first to call a group of stars as such. The name Pegasus is a beautiful winged horse included in Greek mythology....
