History Behind Science

While empirical investigations of the natural world have been described since antiquity (for example, by Aristotle, Theophrastus and Pliny the Elder), and scientific methods have been employed since the Middle Ages (for example, by Alhazen, Abu Rayhan Biruni and Roger Bacon), the dawn of modern science is generally traced back to the early modern period during what is known as the Scientific Revolution of the 16th and 17th centuries.[5]
The word "science" comes through the Old French, and is derived in turn from the Latin scientia, "knowledge", the nominal form of the verb scire, "to know".

From the Middle Ages to the Enlightenment, science or scientia meant any systematic recorded knowledge.[7] Science therefore had the same sort of very broad meaning that philosophy had at that time. In other languages, including French, Spanish, Portuguese, and Italian, the word corresponding to science also carries this meaning.
Prior to the 1700s, the preferred term for the study of nature was natural philosophy, while English speakers most typically referred to other philosophical disciplines (such as logic, metaphysics, epistemology, ethics and aesthetics) as moral philosophy. Today, "moral philosophy" is more-or-less synonymous with "ethics". Far into the 1700s, science and natural philosophy were not quite synonymous, but only became so later with the direct use of what would become known formally as the scientific method. By contrast, the word "science" in English was still used in the 17th century (1600s) to refer to the Aristotelian concept of knowledge which was secure enough to be used as a sure prescription for exactly how to do something. In this differing sense of the two words, the philosopher John Locke wrote disparagingly in 1690 that "natural philosophy... [continues]
