Music visualization, a feature found in electronic music visualizers and media player software, generates animated imagery based on a piece of music. The imagery is usually generated and rendered in real time and synchronized with the music as it is played, but some visualizations are pre-rendered.
Visualization techniques range from simple ones (e.g., a simulation of an oscilloscope display) to elaborate ones, which often include a plurality of composited effects. The changes in the music’s loudness and frequency spectrum are among the properties used as input to the visualization.

Takotsubo cardiomyopathy, is a sudden temporary weakening of the myocardium (the muscle of the heart). Because this weakening can be triggered by emotional stress, such as the death of a loved one, the condition is also known as broken heart syndrome. A tako tsubo is a jar-shaped, Japanese octopus trap that bears a resemblance to a heart experiencing Takotsubo cardiomyopathy: a bulging left ventricular apex and a preserved base of the left ventricle. The cause of the syndrome is not entirely understood, and is currently thought to involve high circulating levels of catecholamines (fight-or-flight hormones like adrenaline).
Evaluation of individuals with takotsubo cardiomyopathy typically includes a coronary angiogram, which will not reveal any significant blockages that would cause the left ventricular dysfunction. Provided that the individual survives their initial presentation, the left ventricular function improves within two months. Takotsubo cardiomyopathy is more commonly seen in post-menopausal women, and those with a history of a recent severe emotional or physical stress. A 2008 study by life insurance companies indicated that in the year following a loved one’s death, women were more than twice as likely to die than normal, and men more than six times as likely.

The Pony Express was a fast mail service crossing the Great Plains, the Rocky Mountains, and the High Sierras from Missouri to California, founded in 1860. It became the west’s most direct means of east-west communication before the telegraph and was vital for tying California closely with the Union just before the American Civil War. Patee House (a historic hotel in St. Joseph, Missouri) served as the Pony Express headquarters from 1860 to 1861. It is one block away from the home of infamous outlaw Jesse James, where he was shot and killed by Robert Ford. After his murder, Jesse James’ family took up lodging at the hotel.
Messages were carried by horseback riders in relays to stations across the prairies, plains, deserts, and mountains of the Western United States. For its 18 months of operation, it briefly reduced the time for messages to travel between the Atlantic and Pacific coasts to about ten days, with telegraphic communication covering about half the distance across the continent and mounted couriers the rest. The continued popularity of the Pony Express can be linked to Buffalo Bill Cody who claimed to have been an Express rider.

‘Silent Garfield‘ refers to the removal of Garfield’s thought balloons from his comic strips. A webcomic called Arbuckle does the above but also redraws the originals in a different art style. Garfield changes from being a comic about a sassy, corpulent feline, and becomes a compelling picture of a lonely, pathetic, delusional man who talks to his pets.
Another variation along the same lines, called ‘Realfield’ or ‘Realistic Garfield,’ is to redraw Garfield as a real cat as well as removing his thought balloons. Still another approach to editing the strips involves removing Garfield and other main characters from the originals completely, leaving Jon talking to himself, such as in ‘Garfield Minus Garfield’ by Dan Walsh.

A telomere [tel-uh-meer] is a protective region of repetitive DNA at the end of a chromosome, The telomere regions deter the degradation of genes near the ends of chromosomes by allowing for the shortening of chromosome ends, which necessarily occurs during chromosome replication. The telomeres are disposable buffers blocking the ends of the chromosomes and are consumed during cell division and replenished by an enzyme, the telomerase reverse transcriptase.
The telomere shortening mechanism normally limits cells to a fixed number of divisions, and animal studies suggest that this is responsible for aging on the cellular level and sets a limit on lifespans. Telomeres also protect a cell’s chromosomes from fusing with each other or rearranging — abnormalities that can lead to cancer — and so cells are destroyed when their telomeres are consumed. Most cancers are the result of ‘immortal’ cells that have ways of evading this programmed destruction.

Googie architecture (also known as populuxe or Doo-Wop) is a form of modern architecture and a subdivision of futurist architecture, influenced by car culture and the Space and Atomic Ages. Originating in Southern California during the late 1940s and continuing approximately into the mid-1960s, the types of buildings that were most frequently designed in a Googie style were motels, coffee houses and bowling alleys.
The school later became widely-known as part of the Mid-Century modern style, and some of those more notable variations represent elements of the populuxe aesthetic, as in Eero Saarinen’s TWA Flight Center. Features of Googie include upswept roofs, curvaceous, geometric shapes, and bold use of glass, steel and neon. Googie was also characterized by Space Age designs that depict motion, such as boomerangs, flying saucers, atoms and parabolas, and free-form designs such as ‘soft’ parallelograms and the ubiquitous artist’s palette motif.

The TI-83 series of graphing calculators is manufactured by Texas Instruments. The original TI-83 is itself an upgraded version of the TI-82. Released in 1996, it is one of the most used graphing calculators for students. TI replaced the TI-83 with the TI-83 Plus calculator in 1999, which included flash memory, enabling the device’s operating system to be updated if needed, or for large new Flash Applications to be stored, accessible through a new Apps key.
The Flash memory can also be used to store user programs and data. In 2001 the TI-83 Plus Silver Edition was released, which featured approximately nine times the available Flash memory, and over twice the processing speed (15 MHz) of a standard TI-83 Plus.

Palladium [puh-ley-dee-uhm] is a chemical element with the chemical symbol Pd and an atomic number of 46. Palladium is a rare and lustrous silvery-white metal that was discovered in 1803 by William Hyde Wollaston, who named it after the asteroid Pallas, which was named after the epithet of the Greek goddess Athena, acquired by her when she slew Pallas.
Palladium, along with platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). Platinum group metals share similar chemical properties, but palladium has the lowest melting point and is the least dense of these precious metals.

A hallmark is an official mark or series of marks struck on items made of precious metals — platinum, gold, silver and in some nations, palladium. In a more general sense, the term hallmark can also be used to refer to any distinguishing characteristic or trait Historically, hallmarks were applied by a trusted party: the ‘guardians of the craft’ or nowadays by an assay office.
Hallmarks are a guarantee of certain purity or fineness of the metal as determined by formal metal (assay) testing. Hallmarks are often confused with ‘trademarks’ or ‘maker’s mark.’ Hallmarks are an official mark of guaranteed metal content, trademarks are the mark of a manufacturer to distinguish his products from other manufacturers’ products.

The MGB is a sports car launched by MG Cars in 1962 to replace the MGA and manufactured until 1980. The MGB was a relatively modern design at the time of its introduction. It utilized a monocoque structure that reduced both weight and manufacturing costs as well as adding chassis strength. This was a considerable improvement on traditional body-on-frame construction. The MGB’s performance was brisk for the period, with a 0–60 mph time of just over 11 seconds, aided by the relatively light weight of the car. Handling was one of the MGB’s strong points. The 3-bearing 1798 cc B-Series engine produced 95 hp (71 kW) at 5,400 rpm.
In 1974, as US air pollution emission standards became more rigorous, US-market MGBs were de-tuned for compliance. As well as a marked reduction in performance, the MGB gained an inch in ride height and the distinctive rubber bumpers which came to replace the chrome for all markets. Nearly half million MGBs were produced and about a third of them remain today (on the roads and garages of their owners). With plenty of cars available and a large supply of reasonably priced parts, MGBs are very inexpensive cars. Prices fluctuate depending of year and condition, early chrome-bumper cars and MGB GTs carrying a premium.
