Anti-War Politics

The anti-war movement and message has probably been going on for as long as war itself. In more recent times however, the anti-war movement has become a potent political force that has helped to change the nature of public policy and influence the decisions of various national governments. The term ‘anti-war’ can refer to a particular nations decision to avoid a war situation, although it is also applied to individual movements within a nation who may already be at war.

In mineralogy, diamond (from the ancient Greek αδάμας – adámas "unbreakable") is an allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at ambient conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools.
