France has the most time zones in the world. There are currently 12 time-zones in France. Time zones are important tools that help in measuring time across different regions of the world or even in large countries. For social, legal, or commercial purposes, the world is divided into different time zones. Large countries such as Russia and the United States observe more than one time-zone. Though France is a relatively small country, covering an area of 247,368 square miles, it observes 12 time-zones. France has the largest number of time zones in the world because its territories are spread across the globe. Metropolitan France, which is located in Europe and comprises Corsica along with nearby islands in the Mediterranean Sea, Atlantic Ocean, and the English Channel, observes a single time-zone. The rest of the 11 time-zones are observed in the overseas territories of the country.

Short for facsimile machine, a device that can send or receive pictures and text over a telephone line. Fax machines work by digitizing an image -- dividing it into a grid of dots. Each dot is either on or off, depending on whether it is black or white. Electronically, each dot is represented by a bit that has a value of either 0 (off) or 1 (on). In this way, the fax machine translates a picture into a series of zeros and ones (called a bit map) that can be transmitted like normal computer data. On the receiving side, a fax machine reads the incoming data, translates the zeros and ones back into dots, and reprints the picture. A fax machine consists of an optical scanner for digitizing images on paper, a printer for printing incoming fax messages, and a telephone for making the connection. The optical scanner generally does not offer the same quality of resolution as stand-alone scanners. Some printers on fax machines are thermal,which means they require a special kind of paper. Some o

The Scoville scale is a measurement of the pungency (spiciness or "heat") of chili peppers and other spicy foods, as recorded in Scoville Heat Units (SHU) based on the concentration of capsaicinoids, among which capsaicin is the predominant component. The scale is named after its creator, American pharmacist Wilbur Scoville, whose 1912 method is known as the Scoville organoleptic test. The Scoville organoleptic test is the most practical method for estimating SHU and is a subjective assessment derived from the capsaicinoid sensitivity by people experienced with eating hot chilis. An alternative method, using high-performance liquid chromatography (HPLC) can be used to analytically quantify the capsaicinoid content as an indicator of pungency. As of 2011, the subjective organoleptic test has been largely superseded by analytical methods such as chromatography.

Aircraft tires are filled with nitrogen because nitrogen gas is mostly inert, meaning that it requires more energy to react with other substances. This is important because at elevated temperatures, oxygen can react with rubber. Oxidized rubber is weaker than non-oxidized rubber, and weaker tires are not preferred.  Oxygen diffuses through rubber much faster than nitrogen. This means that tires filled with 95% nitrogen (the standard percentage of nitrogen gas for inflation purposes) will maintain pressure longer. This leads to less maintenance, which lowers costs.
