Assuming a Greek origin, chemistry is defined as follows: Chemistry, from the Greek word χημεία (khēmeia) meaning "cast together" or "pour together", is the science of matter at the atomic to molecular scale, dealing primarily with collections of atoms, such as molecules, crystals, and metals.
The emblem of the dolphin and anchor which has been used since Roman times to illustrate the adage. This example is the printer's mark of Aldus.. Festina lente (Classical Latin: [fɛsˈtiː.naː ˈlɛn.teː]) or speûde bradéōs (σπεῦδε βραδέως, pronounced [spêu̯.de bra.dé.ɔːs]) is a classical adage and oxymoron meaning "make haste slowly" (sometimes rendered in English as ...
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 ...
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
His 1811 paper "Essay on Determining the Relative Masses of the Elementary Molecules of Bodies", he essentially states, i.e. according to Partington's A Short History of Chemistry, that: [9] The smallest particles of gases are not necessarily simple atoms, but are made up of a certain number of these atoms united by attraction to form a single ...
"The mills of God grind slowly, but they grind exceeding small," he said, somewhat impressively. — W. Somerset Maugham, "The Moon and Sixpence" (1919) During the Second World War, both Winston Churchill and Franklin Roosevelt quoted Longfellow when promising retribution for the extermination of the Jews.
Specific recipe trends will surely flow through social media throughout 2025, but these overarching trends will likely set the tone for what’s cool and crave-worthy, the experts we spoke to confirm.
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.
