During that time, he was able to describe the essential traits of the disease. He was also an ophthalmologist. One of his widely recognized works was entitled “Researches into the Anatomy and Pathology of the Eye,” which was released in 1896. The prevalence of this condition is one in every 10,000 births.

Gravity is the scientific term used to refer to the force exerted by a planet on objects nearby. This force is the one responsible for keeping the planets as well as the sun in their orbits. Gravity is also responsible for the development of tides. The force is important to keep high temperature in the stars’ interiors. In order to learn more about this concept, it is necessary to take a look at the history of the discovery of gravity. Read more

Zinc (also identified as spelter) is considered as one of the plentiful elements in the crust of the Earth. Some countries like the United States, Canada and Australia are fortunate to have abundant sources of the element. In order to produce the element, there are process that should be done such as roasting, froth floatation and extraction. This element has various applications in different industries including the wood industry. Before we proceed with the different uses of the metal, it is important to start with the history of zinc. Historical Background Who discovered zinc? According to records, German scientist Andreas Margraf discovered the element in 1746. Even if Margraf was recognized for the discovery of the element, many historians agree that the element was already used by ancient people. One of the evidences that the element was used in early societies is the prehistoric statuette that was recovered in Transylvania, which was made from 87.5 per cent zinc. Aside from this,...

There is no arguing that oxygen is the most important element for all of mankind. Our very life is dependent on it as is numerous other organisms that live on our planet. Our dependence on it is one of the things that limit us from exploring our universe since oxygen is not abundant outside of the Earth. Knowing this dire connection that human kind has to oxygen, it is surprising that only in the eighteenth century did man actually ‘discover’ oxygen. The use of the word discovered must be put into context of course since the discovery of oxygen is unlike other discoveries, such as that of the Americas or that of Australia. This is because man has always intuited through analysis the existence of oxygen; it’s just that no one was able to isolate it from air until the eighteenth century. The credit for being the men who discovered oxygen goes to three scientists of that century; three scientists who each claimed the achievement for themselves. Their squabble notwithstanding, each...
