An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.
New models of the structure of the atom led to developments in theories of chemistry and the development of new materials such as nylon and plastics. Advances in biology led to large increases in food production, as well as the elimination of diseases such as polio. A massive amount of new technologies were developed in the 20th century.
The protoscience of chemistry, and alchemy, was unsuccessful in explaining the nature of matter and its transformations. However, by performing experiments and recording the results, alchemists set the stage for modern chemistry. The history of chemistry is intertwined with the history of thermodynamics, especially through the work of Willard ...
The Chemical Pioneer Award, first given in 1966, recognizes chemists or chemical engineers who have made outstanding contributions to advances in chemistry or the chemical profession. [ 4 ] Former Presidents of the Institute include Gustav Egloff who served from 1942 to 1946.
Advances in environmentally focused chemistry Harrison-Meldola Memorial Prizes: Scientist who demonstrates the most meritorious and promising original investigations in chemistry and published results of those investigations Hickinbottom Award: Contributions in the area of organic chemistry from researchers under the age of 35 Interdisciplinary ...
Early experiments in chemistry had their roots in the system of alchemy, a set of beliefs combining mysticism with physical experiments. The science of chemistry began to develop with the work of Robert Boyle, the discoverer of gases, and Antoine Lavoisier, who developed the theory of the conservation of mass.
Showed that diamonds are a form of carbon, when he burned samples of carbon and diamond then showed that neither produced any water and that both released the same amount of carbon dioxide per gram. 1772: Carl Wilhelm Scheele: Showed that graphite, which had been thought of as a form of lead, was instead a type of carbon. 1772: Daniel Rutherford
Great advances in science have been termed "revolutions" since the 18th century. For example, in 1747, the French mathematician Alexis Clairaut wrote that "Newton was said in his own life to have created a revolution". [11] The word was also used in the preface to Antoine Lavoisier's 1789 work announcing the discovery of oxygen. "Few ...
