2 NICOLAUS COPERNICUS A RENAISSANCE MAN WHO STARTED A SCIENTIFIC REVOLUTION Born February 19, 1473 Torun, Poland Died May 24, 1543 Frombork, Poland By Cynthia Stokes Brown, adapted by Newsela

3 In the middle of the 16th century a Catholic, Polish astronomer, Nicolaus Copernicus, synthesized observational data to formulate a comprehensive, Sun-centered cosmology, launching modern astronomy and setting off a scientific revolution. 2 3

4 Have you ever heard the expression Renaissance man? The phrase describes a well-educated person who does well in many different fields. The Renaissance is the name for a period in European history, the 14th through the 17th centuries, when the continent emerged from the Dark Ages. The Renaissance brought a renewed interest in the arts and sciences to Europe. Nicolaus Copernicus was a true Renaissance man. He became a mathematician, an astronomer, a church judge with a doctorate in law, a physician, a translator, an artist, an official in the Catholic Church, a governor, a diplomat, and an economist. He spoke German, Polish, and Latin, and understood Greek and Italian. Family and studies Copernicus was born February 19, 1473 to wealthy parents who both died when he was young. He and his siblings were adopted by his rich and powerful uncle. He studied mathematics and astronomy at the University of Krakow from 1492 to He changed his last name, Koppernigk, to its Latin version while at the university, since scholars used Latin as their common language. Copernicus also studied law at the University of Bologna and medicine at the University of Padua. These two schools were among the best in the world at that time. It was not an easy journey, though. It took two months to travel from Poland to Italy by foot and horseback As a student, Copernicus began to question what he was taught. He learned Aristotle s and Ptolemy s views of the Universe. His professors believed that the Earth was at the center of the Universe and it did not move. Copernicus began to question those ideas. Even as a young university student, Copernicus was beginning to see a Universe where the Earth moved. Life at the cathedral In 1497, Copernicus was elected canon of the cathedral in Frombork. Canons were responsible for all aspects of a cathedral. He had many duties as canon, including mapmaking, collecting taxes and managing the money, serving as a secretary, and practicing medicine. His life was half-religious and half-scientific. He continued making astronomical observations from his tower apartment. He didn t have a telescope, because the telescope hadn t been invented yet. Instead, he looked through a simple metal tube. He also had a device that looked like two wooden yardsticks joined together. He used it to measure the angles of stars and planets in the sky. By 1514, Copernicus had written a short report that explained his heliocentric theory. In it, Copernicus confidently said that the Earth both revolved on its axis and orbited around the Sun. A heliocentric theory Copernicus worked on a major astronomical book for 16 years. He didn t want to publish it because he was afraid of the fierce debate it would spark. He also hoped to gather more data. In 1541, when he was 68, he agreed to publish it after a mathematician friend helped convince him. Copernicus titled his master work On the Revolutions of the Celestial Spheres. In this work, Copernicus began by describing the shape of the Universe. He provided a diagram to help the reader. In the diagram, he showed the outer circle that contained all the fixed stars, much further away than previously thought. Inside the fixed stars were Saturn, then Jupiter, and Mars, then Earth, Venus, and Mercury. All of these planets made circular orbits around the Sun in the center. 4 5

Death and legacy Legend has it that Copernicus was on his deathbed, in a coma, when his great work was published. He awoke from the coma to see the first copy of his book.

5 Death and legacy Legend has it that Copernicus was on his deathbed, in a coma, when his great work was published. He awoke from the coma to see the first copy of his book. After he had seen and appreciated his accomplishment, he died peacefully on May 24, He didn t live to hear the praise or criticism of his ideas. The Catholic Church banned Copernicus s book more than 70 years later. It also banned any other book that agreed with Copernicus s heliocentric argument. In 1633, Galileo Galilei was convicted of defying Church teachings for following Copernicus s position. Copernicus s heliocentric model was not widely accepted until Isaac Newton developed the Law of Universal Gravitation in This law explained how gravity would cause the planets to orbit the Sun, which is much larger than the Earth. It also explained why small moons around Jupiter and Earth orbited their home planets. The Copernican model from the Harmonica Macrocosmica atlas by Andreas Cellarius He calculated the time required for each planet to complete its orbit, and was off by only a bit. Copernicus s theory can be summarized like this: The center of the Earth is not the center of the Universe, only of Earth s gravity and of the lunar sphere. The Sun is fixed, and all other spheres revolve around the Sun. Earth has more than one motion, turning on its axis and moving in a spherical orbit around the Sun. The stars are fixed, but appear to move because of the Earth s motion. It appears that the Sun rises each morning and sets every night. But really, it is the Earth, not the Sun, that is moving. Copernicus asked people to give up thinking that they lived in the center of the Universe. For him, the idea of the Sun shining on all the planets as they rotated around it had great beauty and simplicity. 6 7

Unlike other measurement systems, the Lexile Framework determines reading ability based on actual assessments, rather than generalized age or grade levels. Recognized as the standard for matching readers with texts, tens of millions of students worldwide receive a Lexile measure that helps them find targeted readings from the more than 100 million articles, books and websites that have been measured. Lexile measures connect learners of all ages with resources at the right level of challenge and monitors their progress toward state and national proficiency standards.
