Astronomy – Book Notes 3.2 The Ancient Greek Science - Why does modern science trace its roots to the Greeks? o Ancient Greeks stand out as the first people who tried to explain the motions of astronomical objects by using logic and geometry, without resorting to the supernatural. o Greek philosophers sought to explain the architecture of the universe by constructing models of nature. Model (scientific) : A representation of some aspect of nature that can be used to explain and predict real phenomena without invoking myth, magic, or the supernatural. o Greek models of nature sought to explain things such as the properties of matter and the motions of the stars, Sun, Moon, and planets. . The tilt of the Earth’s axis causes sunlight to fall differently on Earth at different times of year. - How did the Greeks explain planetary motion? o Most Greek philosophers assumed the Earth must reside at the center of the universe.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
