Science
In the 3rd millennium BCE, ancient Egyptian scribes developed a non-positional decimal numbering system to solve practical problems using geometry. They created calendars and healing therapies that involved drug treatments alongside prayers and incantations. Neolithic populations in Upper Egypt constructed megaliths at Nabta Playa to coordinate astronomical observations. Ancient Nubians pioneered early antibiotics and established geometric systems that served as the basis for initial sun clocks. Their trigonometric methodology was comparable to their Egyptian counterparts.
Meanwhile, Mesopotamian scholars used knowledge about natural chemicals to manufacture pottery, faience, glass, soap, metals, lime plaster, and waterproofing. The earliest medical prescriptions appeared in Sumer during the Third Dynasty of Ur. These societies studied animal physiology, anatomy, behavior, and astrology for divinatory purposes. They had an intense interest in medicine but seemed to have little interest in satisfying curiosity beyond practical or religious applications.
The Milesian school, founded by Thales of Miletus, became the first group to attempt explaining natural phenomena without relying on the supernatural. His successors Anaximander and Anaximenes continued this work. Pythagoreans developed a complex number philosophy that contributed significantly to mathematical science. Leucippus and his student Democritus developed the theory of atoms. Epicurus later adopted a canon which established physical criteria or standards of scientific truth.
Hippocrates established the tradition of systematic medical science and is known as the Father of Medicine. Socrates applied philosophy to the study of human matters including human nature and political communities. Plato's dialogues documented the Socratic method as a dialectic approach to hypothesis elimination. Aristotle created a systematic programme of teleological philosophy in the 4th century BCE. Aristarchus of Samos proposed a heliocentric model of the universe in the 3rd century BCE, though it was widely rejected until the Renaissance.
During the Abbasid period, Islamic study of Aristotelianism flourished in the House of Wisdom established in Baghdad, Iraq. This institution flourished until the Mongol invasions in the 13th century. Ibn al-Haytham, better known as Alhazen, used controlled experiments in his optical study. Schramm sums up his achievement in the development of scientific method beyond any dispute. Avicenna's compilation of The Canon of Medicine became one of the most important publications in medicine and was used until the 18th century.
The Sasanian Empire established the medical Academy of Gondishapur by the 6th and 7th centuries. Greek, Syriac, and Persian physicians considered this the most important medical hub of the ancient world. Arabic translations of Greek classical texts were improved and developed by Arabic scientists. These works later entered Western Europe during the Renaissance, reviving natural philosophy after the collapse of the Western Roman Empire.
Nicolaus Copernicus formulated a heliocentric model of the Solar System in the 16th century stating that planets revolve around the Sun instead of Earth. Johannes Kepler improved Copernicus' model through the discovery of Kepler's laws of planetary motion. Galileo made significant contributions to astronomy, physics, and engineering but became persecuted after Pope Urban VIII sentenced him for writing about the heliocentric model.
Francis Bacon emphasized the importance of experiment over contemplation and promoted the idea that science should study the laws of nature. René Descartes argued that mathematics rather than geometry should be used to study nature. Isaac Newton formed the foundation of classical mechanics with his work published in 1687. Gottfried Wilhelm Leibniz incorporated terms from Aristotelian physics now used in a new non-teleological way. The Age of Enlightenment declared the purpose of science as producing wealth and inventions that would improve human lives.
Modern science is commonly divided into three major branches: natural science, social science, and formal science. Natural science studies the physical world and can be subdivided into life science and physical science. Physical science includes physics, chemistry, astronomy, and earth science. Social science examines human behavior and the functioning of societies including anthropology, economics, history, political science, psychology, and sociology.
Formal science generates knowledge using formal systems like mathematics, systems theory, and theoretical computer science. These disciplines rely exclusively on deductive reasoning without the need for empirical evidence. Applied sciences use scientific method and knowledge to attain practical goals such as engineering and medicine. Computational science applies computer simulations to enable better understanding of scientific problems than formal mathematics alone can achieve.
The professionalisation of science began in the 19th century through the creation of national academies of sciences. The Italian Accademia dei Lincei formed in 1603 followed by the British Royal Society in 1660. The French Academy of Sciences emerged in 1666 while the American National Academy of Sciences appeared in 1863. The German Kaiser Wilhelm Society was established in 1911 and the Chinese Academy of Sciences in 1949.
Scientific journals began publication with Philosophical Transactions starting in 1665. By 1981 one estimate placed the number of scientific and technical journals at 11,500. Marie Curie became the first person to win two Nobel Prizes in Physics in 1903 and Chemistry in 1911. Science awards are usually given to individuals or organizations that have made significant contributions to a discipline through prestigious institutions.
