Dr. Jekyll and Mr. Hyde is a 1931 American pre-Code horror film, directed by Rouben Mamoulian and starring Fredric March, who plays a possessed doctor who tests his new formula that can unleash people's inner demons. The film is an adaptation of The Strange Case of Dr Jekyll and Mr Hyde, the 1886 Robert Louis Stevenson tale of a man who takes a potion which turns him from a mild-mannered man of science into a homicidal maniac. The film was a critical and commercial success upon its release. Nominated for three Academy Awards, March won the award for Best Actor, sharing the award with Wallace Beery for The Champ. Plot Dr. Henry Jekyll (Fredric March), a kind English doctor in Victorian London, is certain that within each man lurks impulses for both good and evil. He is desperately in love with his fiancée Muriel Carew (Rose Hobart) and wants to marry her immediately. But her father, Brigadier General Sir Danvers Carew (Halliwell Hobbes), orders them to wait. One night, while walking home with his colleague, Dr. John Lanyon (Holmes Herbert), Jekyll...

A diamond anvil cell (DAC) is a high-pressure device used in geology, engineering, and materials science experiments. It enables the compression of a small (sub-millimeter-sized) piece of material to extreme pressures, typically up to around 100–200 gigapascals, although it is possible to achieve pressures up to 770 gigapascals (7,700,000 bars or 7.7 million atmospheres).The device has been used to recreate the pressure existing deep inside planets to synthesize materials and phases not observed under normal ambient conditions. Notable examples include the non-molecular ice X, polymeric nitrogen and metallic phases of xenon, lonsdaleite, and potentially metallic hydrogen.A DAC consists of two opposing diamonds with a sample compressed between the polished culets (tips). Pressure may be monitored using a reference material whose behavior under pressure is known. Common pressure standards include ruby fluorescence, and various structurally simple metals, such as copper or platinum. The uniaxial pressure supplied by the DAC may be transformed into uniform hydrostatic pressure using a pressure-transmitting medium, such as argon, xenon, hydrogen, helium, paraffin...

The Fabian strategy is a military strategy where pitched battles and frontal assaults are avoided in favor of wearing down an opponent through a war of attrition and indirection. While avoiding decisive battles, the side employing this strategy harasses its enemy through skirmishes to cause attrition, disrupt supply and affect morale. Employment of this strategy implies that the side adopting this strategy believes time is on its side, usually because the side employing the strategy is fighting in, or close to, their homeland and the enemy is far from home and by necessity has long and costly supply lines. It may also be adopted when no feasible alternative strategy can be devised. By extension, the term is also applied to other situations in which a large, ambitious goal is seen as being out of reach, but may be accomplished in little steps. Rome versus Carthage: The Second Punic War This strategy derives its name from Quintus Fabius Maximus Verrucosus, the dictator of the Roman Republic given the task of defeating the great Carthaginian general Hannibal in southern Italy during the Second...

Pizzicato (, Italian: [pittsiˈkaːto]; translated as "pinched", and sometimes roughly as "plucked") is a playing technique that involves plucking the strings of a string instrument. The exact technique varies somewhat depending on the type of instrument: On bowed string instruments it is a method of playing by plucking the strings with the fingers, rather than using the bow. This produces a very different sound from bowing, short and percussive rather than sustained. On keyboard string instruments, such as the piano, pizzicato may be employed (although rarely seen in traditional repertoire, this technique has been normalized in contemporary music, with ample examples by George Crumb, Toru Takemitsu, Helmut Lachenmann, and others) as one of the variety of techniques involving direct manipulation of the strings known collectively as "string piano". On the guitar, it is a muted form of plucking, which bears an audible resemblance to pizzicato on a bowed string instrument with its relatively shorter sustain. It is also...
