The Scientific Method
The Scientific Method is general set of procedures used for gathering and interpreting objective information in a way that minimizes error and yields dependable generalizations. This method has no creator but it was used by some of the most well known philosophers and scientist. -

The Ptolemaic System
Ptolemy a Greek writer, known as a mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. His writings represent the culminating achievement of Greco-Roman science, particularly his geocentric (Earth-centered) model of the universe. -

Heliocentric Model
Nicholas Copernicus, a polish astronomer proved with his theory that the sun and not the earth is the center of the universe. -

Kepler's discovery of The Heliocentric Model
Just like Copernicus, Kepler also believed the sun was the center of the universe but he didn't believe that planetary motion occurred in circles but in oval motion. -
The Microscope
the first microscope was created by Zacharias Janssen, who was a Dutch maker of eyeglasses. Later, the microscope was used by Anton van Leeuwenhoek to observe bacteria and examine red blood cells. -
Galileo Galiei and his discovery
Galileo Galiei, an Italian polymath: astronomer, physicist, engineer, philosopher, and mathematician. He improved upon the telescope he observed and described the moons of Jupiter, the rings of Saturn, the phases of Venus, sunspots and the rugged lunar surface. -
Galileo and his discovery of life beyond what we see
Galileo also believed in the heliocentric model but when he improved upon the telescope he discovered that there is more to the planets than what see he saw the moons of Jupiter, mountains on the moon, and sunspots. -
William Harvey and circulation
William Harvey, an English physician,was the first known physician to describe completely and in detail the systemic circulation and properties of blood being pumped to the brain and body by the heart. -
The Barometer
The world's first barometer was developed by Evangelista Torricelli, who was one of Galileo's students. It was a mercury barometer used to measure atmospheric pressure and predict weather. Even though Evagenlista developed the barometer evidence suggest that scientist and philosophers had concepts of such tool. -
Robert Boyle and his discovery
Robert Boyle, an Irish chemist established that air has weight and his definitions of chemical elements and chemical reactions helped to dissociate chemistry from alchemy. -
Newton laws of motion
Issac Newton developed the theory of gravity. He developed tree laws. The first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. The second law explains how the velocity of an object changes when it is subjected to an external force. The third law states that for every action (force) in nature there is an equal and opposite reaction. These laws explain planetary motion. -
Universal Law of Gravitation
Issac Newton's law of gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. -
Maria winkle Mann and her discovery
Maria Winkle Man, a star of German astronomy who discovered her own comet. As “assistant” to her husband and later to her son, she contributed to establishing the Berlin Academy of Science as a major Center of astronomy. She was also known for her writings on the conjunction of the sun with Saturn, Venus, and Jupiter. -
The thermometer
Gabriel Fahrenheit made the first thermometer using mercury in glass. He also developed the Fahrenheit scale, according to which water freezes at 32 degrees Fahrenheit. Later, Anders Celsius developed another scale for the thermometer. The Celsius scale shows water freezes at 0 degrees Celsius. -
Montesquieu and his impact on government
Montesquieu, a French lawyer, man of letters, and political philosopher developed a main key point present in the U.S.A Constitution, the idea of three branches of government.
