Who Discovered the Slope Formula?

Who Discovered the Slope Formula?
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....

Who Discovered Genetic Engineering?

Who Discovered Genetic Engineering?
When studying the facts about genetic engineering, the names of Herbert Boyer and Stanley Cohen will always be mentioned. In 1973, the two scientists invented a DNA cloning technique. For many historians this was both the discovery and beginning of this science. Cohen and Boyer’s Work Cohen and Boyer utilized enzymes to slice a bacteria plasmid. Then they placed this in another DNA strand. These strands were obtained from the same bacteria. Next, the two inserted frog DNA into the bacteria. Their work proved that mixing and manipulating genes was possible. Today several enzymes are used to slice the DNA in different ways. The mapping of DNA has made it possible to manipulate genes more easily. As more facts about genetic engineering emerged, it became possible for scientists to produce insulin for diabetic patients. At the same time the technique has been employed for making EPO (used to treat patients with kidney ailments). This was followed in 1990 when genetic therapy was invented....

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 Multiple Sclerosis?

Who Discovered Multiple Sclerosis?
An autoimmune disease that affects the central nervous system, specifically the spinal cord and the brain, multiple sclerosis inflict insurmountable amount of suffering and pain to patients. Patients usually experience demyelination, a condition wherein there is damage to the myelin sheath of neurons. Aside from knowing its symptoms, risk factors and treatments, it is also good to know things about the history of this disease including who discovered multiple sclerosis. The Discovery of Multiple Sclerosis Who discovered multiple sclerosis? French neurologist Jean-Martin Charcot was the very first one to describe this medical condition some time in 1868. Because of his numerous contributions to the world of science, he was considered the founder of modern neurology. Aside from neurology, he also contributed a lot to the field of psychology. Additional Facts and Other Important Details The U.S. National Multiple Sclerosis Society defined four subtypes of multiple sclerosis in 1996, namely...

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. He presented a model of the solar system that was heliocentric in nature. This later became among the few established facts about earth’s discovery. Galileo later confirmed Copernicus’ statement. Who Discovered Earth was Not Flat? Ancient people also believed...
