Eratosthenes
He was born in Cyrene Libya. Some of the problems about the Earth that interested Eratosthenes were the people were believing that the sun was directing overhead. The hypothesis Eratosthenes tested to prove that the Sun was not directed overhead but slightly south. Eratosthenes used this information to calculate the circumference of the Earth by measuring the angle of the Sun’s ray off the vertical by dividing the length of the leg opposite of the angle. -

Claudius Ptolemy
He opposed that the Earth was the center of the Universe. He viewed of the cosmos persisted for 1,400 years until it was contradicted by others. He lived in Egypt, Alexandria from about 85 to 165 CE -

Copernicus
A Renaissance man who started a scientific notation. He made the observational data to formulate a comprehensive of the sun centered cosmology. Then launching the modern astronomy and setting a scientific notation. He then wrote about the heliocentric theory -
Jan 22, 1561
Francis Bacon
His works are credited with developing the scientific method and remained influential through the scientific revolution. He discovered and popularized the scientific method, whereby the laws of science are discovered by gathering and analyzing data from experiments and observations, rather than by using logic-based arguments. -

Galileo
An Italian man, he invented the telescope to collect evidence that can support that the Sun is in the center of the Solar System. He then later concluded that the Sun is in the Center of the Solar System, but there was many contraversals against him. He agreed with Copernicus with his observation and claim of the Sun. -
1571
Kepler
She was a leading astronomer of the Scientific Revolution known for formulating the Laws of Planetary Motion. An astronomer, of course, is a person who studies the Sun, stars, planets and other aspects of space. -
Descarte
A skeptical argument attempts to show that we cannot know or be certain of something we ordinarily believe. Descartes considers three increasingly radical skeptical arguments that he has reason to doubt all of his sensory beliefs. The first he rejects, but the second and third he accepts. A person who questioned whether anything can be known with certainty. You can have the problem to doubt yourself and question your own opinions. -
Tycho Brahe
Tycho Brahe proposed a theory of the solar system, which contained elements of both the Earth-centred Ptolemaic system and the Sun-centred Copernican system. In his theory, the other planets revolved around the Sun, which itself revolved around Earth. -
John Locke
John Locke believes that everyone is based on what things are poured into you then no one is better than any other from birth. All men are created equal. We’re born knowing nothing and all of our knowledge comes from. The distinction between primary and secondary qualities explained the disagreements that we all have about our perceptions of the outside world -
Newton
Newton developed the three basic laws of motion and the theory of universal gravity. It then laid out the foundation of the current understanding of physics and the Universe. -
Mendeleev
Dmitri Mendeleev is a Russian chemist and a teacher. He made the Periodic table as a comprehensive way for classifying the chemical elements. -
Marie Curie
Marie Curie had began making many experiments that would involves the science of radioactivity. She invented the x-rays that would help many soldiers during wars. She changed the world of medicine and increase our understanding of the structure of the atom. -
Laviett
Laviett discovered the relationship between the brightness of a star and the time it took for the brightness to began. Then he would estimate the distance between the stars and began mapping the Universe. -
Alfred Wegner
He was born in Berlin, Germany. Alfred Wegener produced evidence in 1912 that the continents are in motion, but because he could not explain what forces could move them, geologists rejected his ideas. -
Hubble
Hubble changed the understanding of the Universe which helped the foundation of the Big Bang theory. At first, he demonstrated that the Universe was much larger before he thought. Then he proved that the Universe is expanding. -
Harry Hess
Almost 50 years later, Harry Hess confirmed Wegener’s ideas by using the evidence of seafloor spreading to explain what moved the
continents.
