The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived “natural philosophy”, which was later transformed by the Scientific Revolution that began in the 16th century as new ideas and discoveries departed from previous Greek conceptions and traditions. The scientific method soon played a greater role in knowledge creation and it was not until the 19th century that many of the institutional and professional features of science began to take shape; along with the changing of “natural philosophy” to “natural science. # ISO certification in India
Modern science is typically divided into three major branches: natural sciences (e.g., biology, chemistry, and physics), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study formal systems, governed by axioms and rules. There is disagreement whether the formal sciences are science disciplines, because they do not rely on empirical evidence. Applied sciences are disciplines that use scientific knowledge for practical purposes, such as in engineering and medicine. # ISO certification in India
New knowledge in science is advanced by research from scientists who are motivated by curiosity about the world and a desire to solve problems. Contemporary scientific research is highly collaborative and is usually done by teams in academic and research institutions, government agencies, and companies. The practical impact of their work has led to the emergence of science policies that seek to influence the scientific enterprise by prioritizing the ethical and moral development of commercial products, armaments, health care, public infrastructure, and environmental protection.
Etymology
The word science has been used in Middle English since the 14th century in the sense of “the state of knowing”. The word was borrowed from the Anglo-Norman language as the suffix -science, which was borrowed from the Latin word Scientia, meaning “knowledge, awareness, understanding”. It is a noun derivative of the Latin sciences meaning “knowing”, and undisputedly derived from the Latin scion, the present participle scīre, meaning “to know”.# ISO certification in India
There are many hypotheses for science‘s ultimate word origin. According to Michiel de Vaan, Dutch linguist and Indo-Europeanist, sciō may have its origin in the Proto-Italic language as *skije- or *skijo- meaning “to know”, which may originate from Proto-Indo-European language as *skh1-ie, *skh1-io, meaning “to incise”. The Lexikon der indogermanischen Verben proposed sciō is a back-formation of nescīre, meaning “to not know, be unfamiliar with”, which may derive from Proto-Indo-European *sekH- in Latin secāre, or *skh2–, from *sḱʰeh2(i)- meaning “to cut”.
In the past, science was a synonym for “knowledge” or “study”, in keeping with its Latin origin. A person who conducted scientific research was called a “natural philosopher” or “man of science”.[35]: 3–15 In 1833, William Whewell coined the term scientist and the term first appeared in literature one year later in Mary Somerville’s On the Connexion of the Physical Sciences, published in the Quarterly Review. # ISO certification in India
History
Earliest roots
The Plimpton 322 tablet by the Babylonians records Pythagorean triples, written in about 1800 BCE
Science has no single origin. Rather, scientific methods emerged gradually over the course of thousands of years, taking different forms around the world, and few details are known about the very earliest developments. Some of the earliest evidence for scientific reasoning is tens of thousands of years old, and women likely played a central role in prehistoric science, as did religious rituals. Some Western authors have dismissed these efforts as “protoscientific”
Direct evidence for scientific processes becomes clearer with the advent of writing systems in early civilizations like Ancient Egypt and Mesopotamia. Although the words and concepts of “science” and “nature” were not part of the conceptual landscape at the time, the ancient Egyptians and Mesopotamians made contributions that would later find a place in Greek and medieval science: mathematics, astronomy, and medicine. From the 3rd millennium BCE, the ancient Egyptians developed a decimal numbering system, solved practical problems using geometry, and developed a calendar.[ Their healing therapies involved drug treatments and the supernatural, such as prayers, incantations, and rituals. # ISO certification in India
The ancient Mesopotamians used knowledge about the properties of various natural chemicals for manufacturing pottery, faience, glass, soap, metals, lime plaster, and waterproofing. They studied animal physiology, anatomy, behavior, and astrology for divinatory purposes. The Mesopotamians had an intense interest in medicine and the earliest medical prescriptions appeared in Sumerian during the Third Dynasty of Ur. They seem to study scientific subjects which have practical or religious applications and have little interest of satisfying curiosity.
Classical antiquity
Plato’s Academy mosaic, made between 100 BCE to 79 AD, shows many Greek philosophers and scholars
In classical antiquity, there is no real ancient analog of a modern scientist. Instead, well-educated, usually upper-class, and almost universally male individuals performed various investigations into nature whenever they could afford the time. Before the invention or discovery of the concept of phases or nature by the pre-Socratic philosophers, the same words tend to be used to describe the natural “way” in which a plant grows, and the “way” in which, for example, one tribe worships a particular god. For this reason, it is claimed that these men were the first philosophers in the strict sense and the first to clearly distinguish “nature” and “convention”.# ISO certification in India
The early Greek philosophers of the Milesian school, which was founded by Thales of Miletus and later continued by his successors Anaximander and Anaximenes, were the first to attempt to explain natural phenomena without relying on the supernatural. The Pythagoreans developed a complex number philosophy and contributed significantly to the development of mathematical science. The theory of atoms was developed by the Greek philosopher Leucippus and his student Democritus. The Greek doctor Hippocrates established the tradition of systematic medical science and is known as “The Father of Medicine”.# ISO certification in India
A turning point in the history of early philosophical science was Socrates’ example of applying philosophy to the study of human matters, including human nature, the nature of political communities, and human knowledge itself. The Socratic method as documented by Plato’s dialogues is a dialectic method of hypothesis elimination: better hypotheses are found by steadily identifying and eliminating those that lead to contradictions. The Socratic method searches for general commonly-held truths that shape beliefs and scrutinizes them for consistency. Socrates criticized the older type of study of physics as too purely speculative and lacking in self-criticism.
Aristotle in the 4th century BCE created a systematic program of teleological philosophy. In the 3rd century BCE, Greek astronomer Aristarchus of Samos was the first to propose a heliocentric model of the universe, with the Sun at the center and all the planets orbiting it. Aristarchus’s model was widely rejected because it was believed to violate the laws of physics, while Ptolemy’s Almagest, which contains a geocentric description of the Solar System, was accepted through the early Renaissance instead. The inventor and mathematician Archimedes of Syracuse made major contributions to the beginnings of calculus. Pliny the Elder was a Roman writer and polymath, who wrote the seminal encyclopedia Natural History. #ISO certification in India
