Physics is an experiential science subject. It is an interaction between theory and observation, where the observer seeks to establish a set of general laws of nature that can be formulated in the language of mathematics. There are several mutually complementary approaches to physics. From one corner, one focuses on the fundamentals of physics. Physics as an empirical science — based on systematic observation of natural phenomena — began around the year 1600 with Galileo Galilei. It is true that physics, astronomy and mathematics had been intensively cultivated within the framework of ancient Greek science, and astronomical observations were already carried out in large numbers. But physics in Greek antiquity did not originate in systematic observations of natural phenomena.
