3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies.

Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally (according to ISO, CIE) understood to include wavelengths from around 780 nm (380 THz) to 1 mm (300 GHz). IR is commonly divided between longer-wavelength thermal IR, emitted from terrestrial sources, and shorter-wavelength IR or near-IR, part of the solar spectrum. Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon.

It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered that infrared radiation is a type of invisible radiation in the spectrum lower in energy than red light, by means of its effect on a thermometer. Slightly more than half of the energy from the Sun was eventually found, through Herschel's studies, to arrive on Earth in the form of infrared. The balance between absorbed and emitted infrared radiation has an important effect on Earth's climate.

Infrared radiation is emitted or absorbed by molecules when changing rotational-vibrational movements. It excites vibrational modes in a molecule through a change in the dipole moment, making it a useful frequency range for study of these energy states for molecules of the proper symmetry. Infrared spectroscopy examines absorption and transmission of photons in the infrared range.

Infrared radiation is used in industrial, scientific, military, commercial, and medical applications. Night-vision devices using active near-infrared illumination allow people or animals to be observed without the observer being detected. Infrared astronomy uses sensor-equipped telescopes to penetrate dusty regions of space such as molecular clouds, to detect objects such as planets, and to view highly red-shifted objects from the early days of the universe. Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, to assist firefighting, and to detect the overheating of electrical components. Military and civilian applications include target acquisition, surveillance, night vision, homing, and tracking. Humans at normal body temperature radiate chiefly at wavelengths around 10 μm. Non-military uses include thermal efficiency analysis, environmental monitoring, industrial facility inspections, detection of grow-ops, remote temperature sensing, short-range wireless communication, spectroscopy, and weather forecasting.

Napoleon Bonaparte (born Napoleone Buonaparte; 15 August 1769 – 5 May 1821), later known by his regnal name Napoleon I, was a French general and statesman who rose to prominence during the French Revolution and led a series of military campaigns across Europe during the French Revolutionary and Napoleonic Wars from 1796 to 1815. He led the French Republic as First Consul from 1799 to 1804, then ruled the French Empire as Emperor of the French from 1804 to 1814, and briefly again in 1815. He was King of Italy from 1805 to 1814 and Protector of the Confederation of the Rhine from 1806 to 1813.

Born on the island of Corsica to a family of Italian origin, Napoleon moved to mainland France in 1779 and was commissioned as an officer in the French Royal Army in 1785. He supported the French Revolution in 1789 and promoted its cause in Corsica. He rose rapidly through the ranks after winning the siege of Toulon in 1793 and defeating royalist insurgents in Paris on 13 Vendémiaire in 1795. In 1796, Napoleon commanded a military campaign against the Austrians and their Italian allies in the War of the First Coalition, scoring decisive victories and becoming a national hero. He led an invasion of Egypt and Syria in 1798 which served as a springboard to political power. In November 1799, Napoleon engineered the Coup of 18 Brumaire against the French Directory and became First Consul of the Republic. He won the Battle of Marengo in 1800, which secured France's victory in the War of the Second Coalition, and in 1803 he sold the territory of Louisiana to the United States. In December 1804, Napoleon crowned himself Emperor of the French, further expanding his power.

The breakdown of the Treaty of Amiens led to the War of the Third Coalition by 1805. Napoleon shattered the coalition with a decisive victory at the Battle of Austerlitz, which led to the dissolution of the Holy Roman Empire. In the War of the Fourth Coalition, Napoleon defeated Prussia at the Battle of Jena–Auerstedt in 1806, marched his Grande Armée into Eastern Europe, and defeated the Russians in 1807 at the Battle of Friedland. Seeking to extend his trade embargo against Britain, Napoleon invaded the Iberian Peninsula and installed his brother Joseph as King of Spain in 1808, provoking the Peninsular War. In 1809, the Austrians again challenged France in the War of the Fifth Coalition, in which Napoleon solidified his grip over Europe after winning the Battle of Wagram. In summer 1812, he launched an invasion of Russia, briefly occupying Moscow before conducting a catastrophic retreat of his army that winter. In 1813, Prussia and Austria joined Russia in the War of the Sixth Coalition, in which Napoleon was decisively defeated at the Battle of Leipzig. The coalition invaded France and captured Paris, forcing Napoleon to abdicate in April 1814. They exiled him to the Mediterranean island of Elba and restored the Bourbons to power. Ten months later, Napoleon escaped from Elba on a brig, landed in France with a thousand men, and marched on Paris, again taking control of the country. His opponents responded by forming a Seventh Coalition, which defeated him at the Battle of Waterloo in June 1815. Napoleon was exiled to the remote island of Saint Helena in the South Atlantic, where he died of stomach cancer in 1821, aged 51.

Napoleon is considered one of the greatest military commanders in history, and Napoleonic tactics are still studied at military schools worldwide. His legacy endures through the modernizing legal and administrative reforms he enacted in France and Western Europe, embodied in the Napoleonic Code. He established a system of public education, abolished the vestiges of feudalism, emancipated Jews and other religious minorities, abolished the Spanish Inquisition, enacted the principle of equality before the law for an emerging middle class, and centralized state power at the expense of religious authorities. His conquests acted as a catalyst for political change and the development of nation states. However, he is controversial because of his role in wars which devastated Europe, his looting of conquered territories, and his mixed record on civil rights. He abolished the free press, ended directly elected representative government, exiled and jailed critics of his regime, reinstated slavery in France's colonies except for Haiti, banned the entry of blacks and mulattos into France, reduced the civil rights of women and children in France, reintroduced a hereditary monarchy and nobility, and violently repressed popular uprisings against his rule.

Propane () is a three-carbon alkane with the molecular formula C₃H₈. It is a gas at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is often a constituent of liquefied petroleum gas (LPG), which is commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation; other constituents of LPG may include propylene, butane, butylene, butadiene, and isobutylene. Discovered in 1857 by the French chemist Marcellin Berthelot, it became commercially available in the US by 1911. Propane has lower volumetric energy density than gasoline or coal, but has higher gravimetric energy density than them and burns more cleanly.

Propane gas has become a popular choice for barbecues and portable stoves because its low −42 °C boiling point makes it vaporise inside pressurised liquid containers (it exists in two phases, vapor above liquid). It retains its ability to vaporise even in cold weather, making it better-suited for outdoor use in cold climates than alternatives with higher boiling points like butane. LPG powers buses, forklifts, automobiles, outboard boat motors, and ice resurfacing machines, and is used for heat and cooking in recreational vehicles and campers. Propane is becoming popular as a replacement refrigerant (R290) for heatpumps also as it offers greater efficiency than the current refrigerants: R410A / R32, higher temperature heat output and less damage to the atmosphere for escaped gasses—at the expense of high gas flammability.

Rotisserie, also known as spit-roasting, is a style of roasting where meat is skewered on a spit – a long, solid rod used to hold food while it is being cooked over a fire in a fireplace or over a campfire, or roasted in an oven. This method is generally used for cooking large joints of meat or entire animals, such as pigs or turkeys. The rotation cooks the meat evenly in its own juices and allows easy access for continuous basting.
