Claw

A claw is a curved, pointed appendage, found at the end of a toe or finger in most amniotes (mammals, reptiles, birds). However, the word "claw" is also often used in reference to an invertebrate. Somewhat similar fine hooked structures are found in arthropods such as beetles and spiders, at the end of the leg or tarsus for gripping a surface as the creature walks. Crabs', lobsters' and scorpions' pincers, or more formally, their "chelae", are sometimes called claws.

A true claw, (as opposed to a chela) is made of hard protein called keratin. Claws are used to catch and hold prey in carnivorous mammals such as cats and dogs, but may also be used for such purposes as digging, climbing trees, self-defense, and grooming, in those and other species.

Similar appendages that are flat and do not come to a sharp point are called nails instead. Claw-like projections that do not form at the end of digits, but spring from other parts of the foot are properly named spurs.

Claws of animals like tigers, lions, and bears were used in making items such as ornaments, pendants, and brooches.

Trinitrotoluene

Trinitrotoluene (/ˌtraɪˌnaɪtroʊˈtɒljuːˌiːn, -ljəˌwiːn/;TNT), or more specifically 2,4,6-trinitrotoluene, is a chemical compound with the formula C₆H₂(NO₂)₃CH₃. This yellow-colored solid is sometimes used as a reagent in chemical synthesis, but it is best known as a useful explosive material with convenient handling properties. The explosive yield of TNT is considered to be the standard measure of strength of bombs and other explosives. In chemistry, TNT is used to generate charge transfer salts.

While the two words are sometimes used interchangeably in common conversation, TNT is not the same as dynamite, a special formatting of nitroglycerin for use as an industrial explosive.

History

TNT was first prepared in 1863 by German chemist Julius Wilbrand and originally used as a yellow dye. Its potential as an explosive was not appreciated for several years mainly because it was so difficult to detonate and because it was less powerful than alternatives. TNT can be safely poured when liquid into shell cases, and is so insensitive that in 1910, it was exempted from the UK's Explosives Act 1875 and was not considered an explosive for the purposes of manufacture and storage.

Race card

Playing the race card is an idiomatic phrase that refers to exploitation of either racist or anti-racist attitudes by accusing others of racism.

Usage

The phrase is commonly used to allege that someone has deliberately and falsely accused another person of being a racist in order to gain some sort of advantage. An example of this use of the term occurred during the O. J. Simpson murder trial, when critics accused the defense of "playing the race card" in presenting Mark Fuhrman's past (e.g., his recorded use of the word "nigger" in addition to his being accused of tampering with murder evidence in prior cases, as well as his use of the Fifth Amendment to avoid potential self-incrimination upon questioning) as a reason to draw his credibility as a witness into question.

Stanford professor Richard Thompson Ford has argued that the race card can be played independent of the person making the claim, or the race in question. An example cited was the Hillary Clinton campaign claiming that Obama won the 2008 Democratic Primary in South Carolina due to the disproportionate number of black registered Democrats in the state, implying more racism in the general population.
