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 .
Nicholas Copernicus was 15 century astronomer and mathematician, translator artist and physicist among other things He is best known as the first astronomer to put forward the idea of a system in which the planets and planetary objects orbit the Sun. By 1508, Copernicus had begun to create his model of the planetary system, suggesting that the Sun, and not our Earth, was the centre of the Universe. His model of the Universe was accepted, whereas earlier models had not been, because his was more detailed and accurate. He also had a better formula for the calculation of the positions of the planets at different times of the year. The Roman Catholic Church criticised Copernicus' theories. It went so far as to ban his book 'De Revolutionibus Orbium Coelestium,' after he died, and it remained a forbidden book for almost three hundred years. The ideas of Copernicus were instrumental in the evolution of the field of astronomy. In fact, almost every notable astronomer who came afte...
