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.
Physical Chemistry
Physical chemistry is the study of macroscopic, atomic, subatomic, and particulate phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibrium.
State
We have entered a time of global transition marked by uniquely contradictory trends. Regional and continental associations of States are evolving ways to deepen cooperation and ease some of the contentious characteristics of sovereign and nationalistic rivalries. National boundaries are blurred by advanced communications and global commerce, and by the decisions of States to yield some sovereign prerogatives to larger, common political associations. At the same time, however, fierce new assertions of nationalism and sovereignty spring up, and the cohesion of States is threatened by brutal ethnic, religious, social, cultural or linguistic strife. Social peace is challenged on the one hand by new assertions of discrimination and exclusion and, on the other, by acts of terrorism seeking to undermine evolution and change through democratic means.

State
The complex notion of the ‘provisional’ character of the State is the reason why the attitude of the first Christians toward the State is not unitary, but rather appears to be contradictory. I emphasize, that it appears to be so. We need only mention Romans 13:1, ‘Let every man be subject to the powers that be ... ,’ alongside Revelation 13: the State as the beast from the abyss.
Oscar Cullmann, The State in the New Testament.
Chemistry
Modern warfare, we discovered, was to a far greater extent than ever before a conflict of chemists and manufacturers. Manpower, it is true, was indispensable, and generalship will always, whatever the conditions, have a vital part to play. But troops, however brave and well led, were powerless under modern conditions unless equipped with adequate and up-to-date artillery (with masses of explosive shell), machine-guns, aircraft and other supplies. Against enemy machine-gun posts and wire entanglements the most gallant and best-led men could only throw away their precious lives in successive waves of heroic martyrdom. Their costly sacrifice could avail nothing for the winning of victory.
David Lloyd George (1938) War Memoirs
Water is essential to life, but every year millions of the chemicals produced together with their reactants and by-products enter the water cycle. Many of these chemicals currently remain unidentified, and the risk posed to human health and the environment cannot be fully determined.
