Science
Science (from the Latin scientia, meaning "knowledge" or "to know") is the effort to discover, and increase human understanding of how the physical world works. Through controlled methods, scientists use observable physical evidence of natural phenomena to collect data, and analyze this information to explain what and how things work. Such methods include experimentation that tries to simulate natural phenomena under controlled conditions and thought experiments. Knowledge in science is gained through research.
The word science is derived from the Latin word scientia for knowledge, the nominal form of the verb scire, "to know". The Proto-Indo-European (PIE) root that yields scire is *skei-, meaning to "cut, separate, or discern". Other words from the same root include Sanskrit chyati, "he cuts off", Greek schizo, "I split" (hence English schism, schizophrenia), Latin scindo, "I split" (hence English rescind).[1] From the Middle Ages to the Enlightenment, science or scientia meant any systematic recorded knowledge.[2] Science therefore had the same sort of very broad meaning that philosophy had at that time. In other languages, including French, Spanish, Portuguese, Italian, Polish and Russian, the word corresponding to science also carries this meaning.
