Who Discovered Chocolate?

Who Discovered Chocolate?
Introduction Chocolate is made from cacao beans. People have cultivated cacao trees for a very long time. But chocolate as we know it today is a relatively new discovery. Here is a brief history of chocolate and cacao and the various discoveries about them. Cultivation of Cacao The Mesoamericans or ancient Native Americans were the first to cultivate cacao. The Olmec Indians would grow them and harvest the seeds as early as 1,500 BC until their demise in 300 BC. From there the cacao became a prized drink among the Mayan and Azec nobilities. This drink is not like the modern chocolate drink. It was bitter and strongly flavored. In fact, the word “chocolate” derives from a Nahuatl term for “bitter water.” What’s in Chocolate All Mesoamericans made chocolate drink in basically the same way. First, the cacao beans were fermented. Then they were dried and the shells removed. The nibs were then ground and turned to a liquid, the fermented chocolate. Modern chocolate is sweeter than...

Who Discovered Radioactivity?

Who Discovered Radioactivity?
Radioactivity has always been around since it is a natural part of the environment we have. It is said to be emitted by some of those things that we use everyday like the computer monitors and TV screens. Hospitals even use radiation for x-rays and other medical purposes. But who discovered radioactivity and made its usage possible? The Early Discovery of Radioactivity A Frenchman named Henri Becquerel is said to be the person who discovered radioactivity. In the year 1896, Becquerel got some naturally fluorescent minerals to be used in an in-depth experiment. The purpose of the experiment was to study the properties of x-rays. The properties were already discovered a year ago by Wilhelm Roentgen, and Becquerel wanted to further examine it. In the experiment, what Becquerel did first was to expose potassium uranyl sulfate to the rays of the sun believing that the energy of the sun will be absorbed by the uranium and then emit it outwards as x-rays. After exposing the potassium uranyl...

Who Discovered the Four Moons of Saturn?
One of the major planets in the Solar System, Saturn is comprised of 61 moons. It is popular for its four visible moons, namely Telesto, Prometheus, Dione and Titan. Aside from these, this planet also has hundreds of moonlets. In addition to these highly interesting details, it is also good to know certain information regarding its history including who discovered the four moons of Saturn. The Discovery of the Four Moons of Saturn Who discovered the four moons of Saturn? The first moon is Titan, which was discovered by Dutch astronomer Christiaan Huygens on March 25, 1655. The second one is Dione, which was discovered by Italian/French astrologer Giovanni Cassini in 1684. The third moon is called Prometheus, which was named after a powerful deity in Greek mythology.

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 Pneumonia?

Who Discovered Pneumonia?
Pneumonia is a very painful disease that affects many people worldwide. It directly affects the lungs, causing them to be inflamed. It is classified into various types, some of the most common of which are parasitic pneumonia, viral pneumonia as well as bacterial pneumonia. Most of the time, patients suffering from this medical condition show signs like breathing difficulty, fever, chest pain and cough. Aside from these highly important things, it is also good to know a little bit of its history including who discovered pneumonia. The Discovery of Pneumonia Who discovered pneumonia? An ancient Greek physician named Hippocrates was the very first one to describe this serious respiratory disease. He lived from 460 B.C. to 370 B.C. He was considered one of the most important individuals in the history of medicine. Furthermore, his contributions are so significant that he is considered until now as the father of medicine. After him came Maimonides, who lived from 1138 to 1204 A.D. He described...
