Overview

Chemistry is the scientific study of the properties and behavior of matter. It is a physical science under natural sciences that covers the elements that make up matter to the compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (cosmochemistry), how medications work (pharmacology), and how to collect DNA evidence at a crime scene (forensics). Chemistry is a study that has existed since ancient times. Over this time frame, it has evolved, and now chemistry encompasses various areas of specialisation, or subdisciplines, that continue to increase in number and interrelate to create further interdisciplinary fields of study. The applications of various fields of chemistry are used frequently for economic purposes in the chemical industry. Etymology

Notable quotes

“The chemists are a strange class of mortals, impelled by an almost insane impulse to seek their pleasures amid smoke and vapour, soot and flame, poisons and poverty; yet among all these evils I seem to live so sweetly that may I die if I were to change places with the Persian king.”
— , Physica subterranea (1667) Quoted in R. Oesper, The Human Side of Scientists (1973), 11
“Chemists do not usually stutter. It would be very awkward if they did, seeing that they have at times to get out such words as methylethylamylophenylium.”
— William Crookes, in: William H. Brock. (1993). The Norton History of Chemistry. W W Norton & Co Inc. p xxvi.
“At this time organic chemistry can drive one completely crazy. It seems to me like a primeval tropical jungle, full of the most remarkable things, an amazing thicket, without escape or end, into which one would not dare to enter.”
— , quoted in Tomas Hudlicky, The Way of Synthesis, 2007.
“Chemistry without catalysis would be a sword without a handle, a light without brilliance, a bell without sound.”
— Alwin Mittasch, as cited in: Ralph Edward Oesper, "Alwin Mittasch," Journal of Chemical Education (1948), 25, 532.
“The unique challenge which chemical synthesis provides for the creative imagination and the skilled hands ensures that it will endure as long as men write books, paint pictures, and fashion things which are beautiful, or practical, or both.”
— Robert Burns Woodward in: Maeve O’Connor (ed.) Pointers & Pathways in Research. , CIBA of India, Bombay (1963) p. 41
“Chemists have been inspired by Nature for hundreds of years, not only trying to understand the chemistry that occurs in living systems, but also trying to extend Nature based on the learned facts.”
— Kirsten Zeitler, "N-Heterocyclic Carbenes: Organocatalysts Displaying Diverse Modes of Action", in Organocatalysis (2008) edited by M.T. Reetz, B. List, S. Jaroch, H. Weinmann
