Chemistry
Chemistry is the scientific discipline involved with compounds composed of atoms, i.e. elements, and molecules, i.e. combinations of atoms: their composition, structure, properties, behavior and the changes they undergo during a reaction with other compounds. Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are four types of chemical bonds: covalent bonds, in which compounds share one or more electron(s); ionic bonds, in which a compound donates one or more electrons to another compound to produce ions (cations and anions); hydrogen bonds; and Van der Waals force bonds.
Chemistry
Once you are there you'll be like a drop of water in a piece of rock crystal- your medium will dignify your commonness.
Thomas Hardy, A Pair of Blue Eyes, 1873
Chemistry
I praise the chemical physicians, for they do not go about gorgeous in satins, silks, and velvets, silver daggers hanging at their sides, and white gloves on their hands, but they tend their work at the fire patiently day and night. They do not go promenading, but seek their recreation in laboratory. They thrust their fingers among the coals into dirt and rubbish and not into golden rings.
Paracelsus (in Jaffe, Bernard. Crucibles: The Story of Chemistry. 4th Edition. New York: Dover, 1976. (Originally, 1930) | Pgs. 13-24)
Chemistry
Every chemical substance, whether natural or artificial, falls into one of two major categories, according to the spatial characteristic of its form. The distinction is between those substances that have a plane of symmetry and those that do not. The former belong to the mineral, the latter to the living world.
Louis Pasteur, Vallery-Radot (ed.), Oeuvres de Pasteur (1922-1939), Vol. I, 331. Quoted in Patrice Debré, Louis Pasteur, trans. Elborg Forster (1994), 261.
An EU-funded project broke down the boundaries amongst research institutions in atmospheric chemistry, offering access to the network facilities to a wider range of researchers.
