From the history of physics
The first scientific knowledge was gathered where people farmed and lived settled lives — Egypt and Babylon — and levers and inclined planes were used to build pyramids and dams. The ancient Greek thinker Aristotle (384–322 BCE) was the first to set out knowledge about physics in book form. Democritus (about 460–370 BCE) said everything consists of indivisible particles, atoms; Archimedes (287–212 BCE) lived in Syracuse and discovered the laws of floating and of the lever. In the Middle Ages science flourished in the East: Beruni studied density, light, sound and the size of the Earth (he found the Earth’s radius to be about 6300 km; today’s mean value is about 6371 km), and Ibn Sina, al-Khwarizmi and Omar Khayyam also contributed greatly. Then physics developed in Europe: the Polish scientist N. Copernicus explained the structure of the solar system correctly, G. Galileo and J. Kepler confirmed it, and I. Newton created the laws of force and motion and studied the colour of light. In the 20th century atomic energy and space flight became possible.
