In the 18th century, the Swedish naturalist and physician Carl Linnaeus introduced the scientific system of classifying plants and animals that is used all over the world to this day. Under this system, each living thing is assigned a name consisting of two Latin words. The first word is the name of the genus, and the second, the species. The classification of living things is called taxonomy. In 1737, Linnaeus published the first edition of his book titled Systema Naturae or System of Nature. Over the years, Linnaeus continued to develop his ideas and add new species so that the book grew in a period of about 30 years from 12 outsize pages in its first edition, to 2400 pages in its twelfth edition. This was the first serious attempt ever made to document all of our planet's species. It was a huge effort and it won Linnaeus acclaim as the 'Father of Taxonomy .
Pythagoras was an Ancient Greek mathematician and philosopher who lived more than 500 years before Christ. He spent most of his life in the Greek colonies in Sicily and southern Italy. He was also a philosopher, and founder of the religious movement called Pythagoreanism. Pythagoras had a group of disciples who followed him around, and taught other people what he had taught them. He made crucial contributions to modern philosophy, as well as mathematics, science, and religious mysticism. It is also believed that he had a significant influence on medicine, music, astronomy, and divination. Pythagoras is best known for the mathematical theory named after him. He is without doubt, one of the greatest scientists not only of the ancient world, but of all time.
