He was the fourth and youngest child born to Nicolaus Copernicus Sr. and Barbara Watzenrode, an affluent copper merchant family. These he inserted into his personal copy of Johannes Regiomontanus’s book. Compare this with Ptolemy’s system, shown previously, in which Earth is wrongly shown closer to Mercury than Venus. After four years at university Nicolaus Copernicus had not graduated.

Ptolemy placed Earth in a privileged location, at the center of the universe. Nicolaus Copernicus was an astronomer and mathematician credited with several discoveries, rather revelations, that had changed our understanding of the universe. Nicolaus Copernicus correctly identified that Terra (the earth) is one of the planets orbiting Sol (the sun). Stars are distant objects that are still, so they do not rotate around the sun. Amazingly, despite it being clear for centuries that our solar system is heliocentric, opinion polls in countries including Germany, the United States, and the United Kingdom show about 1-in-5 or 1-in-6 people still believe that the sun orbits the earth! : Color change allows harm-free health check of living cells, : Shunned after he discovered that continents move, : The dog whisperer who rewrote our immune system’s rules, : In the 1600s found that space is a vacuum, : Aquatic ape theory: our species evolved in water, : Became the world’s most famous codebreaker, : We live at the bottom of a tremendously heavy sea of air, : The first mathematical model of the universe, : Revolutionized drug design with the Beta-blocker, : Discovered our planet’s solid inner core, : Shattered a fundamental belief of physicists, : Unveiled the spectacular microscopic world, : The cult of numbers and the need for proof, : Discovered 8 new chemical elements by thinking, : Record breaking inventor of over 40 vaccines, : Won – uniquely – both the chemistry & physics Nobel Prizes, : Founded the bizarre science of quantum mechanics, : Proved Earth’s climate is regulated by its orbit, : The giant of chemistry who was executed, : The greatest of female mathematicians, she unlocked a secret of the universe, : Pioneer of brain surgery; mapped the brain’s functions, : Major discoveries in chimpanzee behavior, : 6th century anticipation of Galileo and Newton, : Youthful curiosity brought the color purple to all, : Atomic theory BC and a universe of diverse inhabited worlds, : Discovered how our bodies make millions of different antibodies, : Discovered that stars are almost entirely hydrogen and helium.
It was a hypothesis at the time.

His grave was lost for centuries, but found again in 2005.

Nicolaus was the youngest of their four children.
His name at birth was Mikolaj Kopernik. Nicolaus Copernicus - Nicolaus Copernicus - Copernicus’s astronomical work: The contested state of planetary theory in the late 15th century and Pico’s attack on astrology’s foundations together constitute the principal historical considerations in constructing the background to Copernicus’s achievement.

This error led, like Ptolemy’s system, to some awkward mathematical compromises. The printing was supervised by Andreas Osiander, who added a note at the beginning of the book which said that, even though the book’s theory was unusual, if it helped people do astronomy calculations, it didn’t matter if it wasn’t really true. Before concluding that the sun is the center of the universe, he reasoned that every planet or sphere revolving around the sun has the star as its midpoint.

To sum up, what is known as the Copernican revolution refers to the formulation of the Heliocentric theory, which states that the earth and other planets revolve around the sun.

He did, however, add to his book collection: some law books, of course, plus some that had nothing to do with his official course, including: • Cosmography by Claudius Ptolemy   • the Bible is the word of God Copernicus also shows the planets in the correct order.
