Idea of Aristotle, used in the Middle Ages, the earth-centered view of the universe in which scholars believed that the earth was an immovable object located at the center of the universe.
Alexandrian astronomer, (2nd century C.E.), who proposed a geocentric system of astronomy that was undisputed until the ideas of Copernicus changed scientific perception in the 16th century (the 1500's).
A major change in European thought, starting in the mid-1500s, in which the study of the natural world began to be characterized by careful observation and the questioning of accepted beliefs.
Theory developed by Copernicus in that the sun is the center of the universe, (sun-centered), but it did not accurately describe the motions of the planets as observed with new technology, telescopes!
A Polish astronomer, 1473 -1543, who proved that the Ptolemaic system was inaccurate, he proposed the theory that the sun, not the earth, was the center of the solar system. His book, "On the Revolutions of the Heavenly Bodies," was published as he died.
Influenced by Copernicus; Brahe, died 1601, built an observatory and collected data on the locations of stars and planets for over 20 years; His limited knowledge of mathematics prevented him from making much sense out of the data.
Assistant to Tycho Brahe, he took Brahe's data and concluded that certain mathematical laws govern planetary motions. One law showed that the planets revolve around the sun in "elliptical" orbits, not circles as previously thought. He demonstrated mathematically that Copernican theory was essentially correct!
Italain astronomer, he created the modern experimental method. Formulated the law of inertia. Tried for heresy and forced to recant. Saw Jupiter's moons. Wrote Dialogue on the Two Chief Systems of the World. Invented the first astronomical telescope for observing the night sky! Published "Starry Messenger" in 1610, which described his astonishing observations using the telescope.
A logical procedure for gathering and testing ideas; whereby a problem or question is stated, arising from an observation about nature or life; a hypothesis is formed which is then tested for being valid or true, data is analyzed from the test and a conclusion is then stated which either confirms or denies the accuracy of the initial theory proposed in the hypothesis.
English politician and writer, advocated that new knowledge was acquired through an inductive reasoning process (using specific examples to prove or draw conclusion from a general point) called empiricism; rejected Medieval view of knowledge based on tradition, believed it's necessary to collect data, observe, and draw conclusions. This was the foundation of the scientific method
Bacon's theory of inductive reasoning. One must experiment and then draw conclusions based on actual observations and not abstract hypotheses.
Developed analytical geometry, linking algebra to geometry; rather than use experiments, like Bacon, he approached science through mathematics and logic. He based his knowledge on a simple premise, "Cogito, ergo sum!" I think, therefore, I am.
English mathematician and scientist who invented differential calculus and formulated the theory of universal gravitation, a theory about the nature of light, and three laws of motion. His treatise on gravitation, presented in "Principia Mathematica," (1687), was supposedly inspired by the sight of a falling apple. Believed in God as a clockmaker, setting time and motion in order.

Developed 1st thermometer using mercury in a glass, observed water freezing at 32 degrees in 1714. His temperature scale is named after him and is still used today!
A Swedish astronomer, created another scale for measuring temperature in a mercury thermometer in 1742. His scale shows water freezing at 0 degrees and water boiling at 100 degrees.
An ancient Greek anatomists who studied the anatomy of pigs and other animals and made conclusions about human anatomy based on these observations, assuming human anatomy was similar. Medieval scholars accepted his work as FACT.
A Flemish physician, he proved the work of Galen to be false. Vesalius dissected and studied human corpses and published his observations in a book, "On the Structure of the Human Body," in 1543. The book was filled with detailed drawings of actual human organs, bones and muscles!
In the late 1700's, this British physician Jenner inoculated people with small amounts of cowpox to prevent them from getting smallpox (1749-1823). This was the world's first vaccination.
Considered the Father of Modern Chemistry, this man pioneered the use of the scientific method in chemistry. In a book called "The Sceptical Chemyst," (1661) Boyle challenged Aristotle's belief that the physical world consisted of 4 elements - earth, air, fire and water. Boyle proposed that matter was composed of smaller elements that combined in many ways. His greatest contribution to science was in creating Boyle's Law.
The scientific law that describes the relationship between the pressure and volume of a gas at constant temperture; when volume increases, pressure decreases.
the act of injecting a germ into a person's body so as to create an immunity to the disease.
Laws of Gravity
Proposed by Isaac Newton, these laws govern planetary movements as well as motions on earth.
A new intellectual movement that stressed reason and thought and the power of individuals to to solve problems. Known as the Age of Reason, the movement reached its height in the mid-1700's and brought great change to many aspects of Western civilization.
English political thinker of the 17th century, expressed his views in a book, "Leviathan," (1651) in which the people gave up most of their rights to government in order to secure protection and peace. This was agreed upon by the people in a "social contract" with the monarchy which had absolute power over individuals.
English political thinker, proposed that all men are born free and equal and that they have 3 rights: life, liberty and property. Government's purpose is to protect these rights and if it does not, the people have the right to overthrow it. Government's power comes from the consent of the people, the basis for modern democracy today!
Thinkers of the Enlightenment; wrote each other to share ideas. Believed that people could apply reason to all aspects of their lives. Had 5 core beliefs: REASON-truth could be discovered thru reason and logical thinking; NATURE-what was natural was good; HAPPINESS-urged people to find happiness in the here and now, not the afterlife; PROGRESS-society & humankind could improve; LIBERTY-wanted what the English had won in the Glorious Revolution and the English Bill of Rights.
