What the invention is and why is it important -
Jan 1, 1543
The Copernican System
In 1543, Nicolaus Copernicus published his theory. His theory was that the earth was not the center of the universe, but the sun was. Copernicus, against other's beliefs, thought that the sun was the true center of the universe and that all the movements of the planets and the moon were based upon the principal that the sun's gravitational pull directed the orbit of the planets around itself. This theory forever changed the ideas about the movement of the earth, the sun and the moon. -

The pencil
The fist pencil was invented in 1564. It was not invented by one person, but a group of English miners. They came about a huge griphite mine, and thought o fthe pencil. The pencil was a thin rod of soft graphite placed inside a wooden shell. During this time, maimly artists had pencils and used them. This invention changed the way of drawing and writing forever. Also, they're portable and very easy to use. It has been improved, but has not changed all that much and is still hugely mass produced. -
Thermometer
In 1593 the thermometer was invented by Galileo Galilei. Galileo was a Italian mathematician, astronomer, and physicist. The thermometer provided a visual measure of temperature. It was a glass bulb with little tick marks on the side and water inside of it. As it got colder, the water molecules compacted and the water level in the thermometer droped. As it got hotter, the molecules expanded and the water level rose. Thermometersare still used today but instead of water, we use mercury. -
Compound microscope
The compound microscope was invented by a Dutch lens maker. In the year 1595, Zacharias Janssen invented the compound microscope. The microscope was constructed of two tubes with lenses on them. By moving the tubes up and down, Janssen was able to focus the microscope. This provided a magnification power of three to nine times. The importance of this then was the scientists could study something more deeply. Today's microscopes were based off of this invention. -
Refracting telescope
The refracting telescope was invented in 1608. The inventor was a man named Hans Lippershey. He was a Dutch lens maker. The refracting telescope is made up of two lenses that magnify what you are observing. The lense an the end of the telescope, the primary lense, was bigger and thicker, so it did most of the magnification. It contributed to the world of science in that it allowed people to view distant objects up close. People use these telescopes today to analyze visible light. -
Barometer
In 1643 the mercury barometer was invented by Evangelista Torricelli. He was an Italian physicist, and a pupil of Galileo. The barometer measures the pressure of the atmosphere. It wieghs the atmospheric pressure. The barometer was important because it helped people tell the weather. Meteorologists use barometric pressure in thier forcasts today, by using barometers. -
Laws of motion
Isaac Newton came up with his work on the three laws of motion in 1680. He was an English natural philosopher. The three laws of motion explain how an object moves and the reaction of those movements. Newton's theorys are still being tought in school tobay. We wouldn't have an answer to how and why things move the way they do, if it wasn't for the three laws of motion. -
Sextant
In the year 1731, the sextant was invented. It was invented by two men, John Hadley, and Thomas Godfrey. Hadley was from England, and Godfrey was from Philadelphia. The sextant was a device that aligned the earth's horizon with the celestial body it was being aimed towards. In doing this the user was able to navigate his or her way across the seas. This early model has been improved upon, but is still the technology of today's modern sextants.
