Frederick Seitz on Science

“Essentially all civilizations that rose to the level of possessing an urban culture had need for two forms of science-related technology, namely, mathematics for land measurements and commerce and astronomy for time-keeping in agriculture and aspects of religious rituals.”

“Darwin recognized that thus far the civilization of mankind has passed through four successive stages of evolution, namely, those based on the use of fire, the development of agriculture, the development of urban life and the use of basic science for technological advancement.”
