Historic Scientists Nicolaus Copernicus

Nicolaus Copernicus, a renowned Polish astronomer, reshaped humanity's understanding of outer space. Before Copernicus, most scholars believed that Earth was at the center of the universe, with the sun, stars, and planets orbiting around it. However, Copernicus introduced a groundbreaking concept: Earth and the other planets orbit the sun. This idea marked a significant change from beliefs before this time.

Born in Torun, Poland, on February 19, 1473, Copernicus studied various fields including astronomy, mathematics, medicine, and church law, both in Poland and Italy. He later served as an officer in the Roman Catholic Church, all while observing space during his free time.

Copernicus developed numerous theories about the solar system, informing the public that Earth not only revolves around the sun but also rotates on its axis. In 1543, he published his revolutionary ideas in a book. Sadly, he passed away that same year, on May 24, in Poland. Although his work initially faced resistance, subsequent generations recognized that his theories are correct.

Often hailed as the father of modern astronomy, Copernicus's groundbreaking studies led to a fundamental shift in our understanding of celestial mechanics. His theory laid the groundwork for a truly scientific approach to astronomy. His most famous work, Six Books Concerning the Revolutions of the Heavenly Orbs. profoundly influenced scientists including Galileo, Johannes Kepler, and Isaac Newton.

Galileo Galilei

Galileo Galilei, also known as Galileo, played a crucial role in shaping modern science. He was born in Pisa, Italy, on February 15, 1564. Initially studying medicine, he later turned his focus to mathematics.

One of Galileo's early breakthroughs occurred while observing a swinging chandelier in the Cathedral of Pisa. He noticed that, regardless of its size, each swing took the same amount of time. This discovery led to the development of the pendulum clock, which became a significant timekeeping device.

In 1609, Galileo learned about the invention of the telescope and constructed his own. Using this instrument, he made groundbreaking observations of space. On January 7, 1610, he discovered four moons orbiting Jupiter, now called the Galilean satellites. These findings supported the theory proposed by Nicolaus Copernicus in 1530 that the Sun, not Earth, is at the center of our solar system.

Galileo's advocacy for Copernican ideas brought him into conflict with the Roman Catholic Church, which adhered to an Earth-centered view of the universe. Despite orders to refrain from promoting Copernicus's theories, Galileo persisted. This defiance led to his trial by the Inquisition in 1633, resulting in house arrest as punishment.

Despite facing challenges and losing his sight in 1637, Galileo continued his scientific work until his death on January 8, 1642. His willingness to challenge established beliefs and his significant contributions to science have left an enduring legacy.

Isaac Newton

Isaac Newton was a groundbreaking scientist who changed the way we understand how objects move. He was born on December 25, 1642, in Woolsthorpe, England. Newton's father died before he was born so was raised by his grandmother.

When Isaac went to Cambridge University in 1661, he became interested in new ideas from Europe. These ideas stated that Earth and the other planets go around the sun, not the other way around like people traditionally believed.

After college, Isaac went back to his family's farm, but he kept studying and performing experiments. His first big discovery was about light. He figured out that when you shine white light through a triangle-shaped piece of glass, it splits into different colors. He said that white light is made up of lots of mixed colors.

Isaac also wondered why the Moon stays in its path around Earth. He thought it must be because Earth pulls on the Moon, a pull called gravity. Isaac showed that gravity controls not just how the Moon moves, but also how planets move around the sun. Newton also theorized about mathematics as well as science.

From 1669 to 1701, Isaac taught at Cambridge, and in 1703, he became the president of a science group called the Royal Society. In 1705, the queen of England made him a knight. Isaac Newton passed away in London on March 20, 1727.
