Who Discovered Fractals?

Who Discovered Fractals?
Benoit Mandelbrot is usually credited with discovering fractals in 1975. Mandelbrot was the one who invented the word. He was also the first to represent them visually. But some facts about fractals were known to mathematicians as far back as the 17th century. Early Fractal Research A fractal can be described as a pattern that is repeated at every scale. It cannot be replicated by classical geometry. The concept of self similarity was first brought up by the philosopher and mathematician Lebinz in the 17th century. It wasn’t until 1872 before a function appropriate to be termed a fractal came into being. Karl Weierstrass showed an instance of a function that was continuous but could not be differentiated. This definition was improved upon by Helge von Koch in 1904 when he defined it as a Koch curve. A study of the facts about fractals will show it is now called the Koch snowflake. In 1915, Wallow Sierpinski created a triangle and a carpet. In 1938, Paul Levy came up with another fractal...

Who Discovered Magnesium?

Who Discovered Magnesium?
Considered as one of the most abundant elements in our body, magnesium is an alkaline earth metal that plays an essential role in the functioning of biological polyphosphate compounds such as DNA, ATP and RNA. This element is also important to plant growth because it is the chlorophyll’s center. Aside from these, the element has other medical, agricultural and industrial uses. To know more about this element, it is best to start with the history of the discovery of magnesium. Historical Background Who discovered magnesium? Based on records, the metal was extracted and discovered in 1808 in England by Sir Humphry Davy. He extracted the element from the mixture of mercury oxide and magnesia with the use of electrolysis. Davy named the element magnium, however, it was later on called magnesium by other scientists. Even if Davy was credited for the discovery of the alkaline earth metal, Epsom salt, a compound form of the element was already used by a farmer in the country to heal rashes as...
