1815 Eruption Of Mount Tambora
Mount Tambora is a volcano on the island of Sumbawa in present-day Indonesia, then part of the Dutch East Indies, and its 1815 eruption was the most powerful volcanic eruption in recorded human history. This volcanic explosivity index (VEI) 7 eruption ejected of material into the atmosphere, and was the most recent confirmed VEI-7 eruption. Although the Mount Tambora eruption reached a violent climax on 10 April 1815, increased steaming and small phreatic eruptions occurred during the next six months to three years. The ash from the eruption column dispersed around the world and lowered global temperatures in an event sometimes known as the Year Without a Summer in 1816. This brief period of significant climate change triggered extreme weather and harvest failures in many areas around the world. Several climate forcings coincided and interacted in a systematic manner that has not been observed after any other large volcanic eruption since the early Stone Age. Chronology of th ...

Napoleonic Wars
The Napoleonic Wars (1803–1815) were a series of major global conflicts pitting the French Empire and its allies, led by Napoleon I, against a fluctuating array of European states formed into various coalitions. It produced a period of French domination over most of continental Europe. The wars stemmed from the unresolved disputes associated with the French Revolution and the French Revolutionary Wars consisting of the War of the First Coalition (1792–1797) and the War of the Second Coalition (1798–1802). The Napoleonic Wars are often described as five conflicts, each termed after the coalition that fought Napoleon: the Third Coalition (1803–1806), the Fourth (1806–1807), the Fifth (1809), the Sixth (1813–1814), and the Seventh (1815) plus the Peninsular War (1807–1814) and the French invasion of Russia (1812). Napoleon, upon ascending to First Consul of France in 1799, had inherited a republic in chaos; he subsequently created a state with stable financ ...

Mount Tambora
Mount Tambora, or Tomboro, is an active stratovolcano in West Nusa Tenggara, Indonesia. Located on Sumbawa in the Lesser Sunda Islands, it was formed by the active subduction zones beneath it. Before 1815, its elevation reached more than high, making it one of the tallest peaks in the Indonesian archipelago. Tambora violently erupted in a series of eruptions beginning 5 April, 1815, culminating in the largest eruption in recorded human history and the largest of the Holocene (10,000 years ago to present). The magma chamber under Tambora had been drained by previous eruptions and underwent several centuries of dormancy as it refilled. Volcanic activity reached a peak that year, culminating in an explosive eruption. The explosion was heard on Sumatra island, more than away. Heavy volcanic ash rains were observed as far away as Borneo, Sulawesi, Java, and Maluku islands, and the maximum elevation of Tambora was reduced from about to .

First French Empire
The First French Empire, officially the French Republic, then the French Empire (; Latin: ) after 1809, also known as Napoleonic France, was the empire ruled by Napoleon Bonaparte, who established French hegemony over much of continental Europe at the beginning of the 19th century. It lasted from 18 May 1804 to 11 April 1814 and again briefly from 20 March 1815 to 7 July 1815. Although France had already established a colonial empire overseas since the early 17th century, the French state had remained a kingdom under the Bourbons and a republic after the French Revolution. Historians refer to Napoleon's regime as the ''First Empire'' to distinguish it from the restorationist ''Second Empire'' (1852–1870) ruled by his nephew Napoleon III. The First French Empire is considered by some to be a " Republican empire." On 18 May 1804, Napoleon was granted the title Emperor of the French (', ) by the French and was crowned on 2 December 1804, signifying the end of the French ...

Battle Of Waterloo
The Battle of Waterloo was fought on Sunday 18 June 1815, near Waterloo, Belgium, Waterloo (at that time in the United Kingdom of the Netherlands, now in Belgium). A French army under the command of Napoleon was defeated by two of the armies of the Seventh Coalition. One of these was a British-led coalition consisting of units from the United Kingdom of Great Britain and Ireland, United Kingdom, the Netherlands, Kingdom of Hanover, Hanover, Duchy of Brunswick, Brunswick, and Duchy of Nassau, Nassau, under the command of the Duke of Wellington (referred to by many authors as ''the Anglo-allied army'' or ''Wellington's army''). The other was composed of three corps of the Kingdom of Prussia, Prussian army under the command of Field Marshal Gebhard Leberecht von Blücher, von Blücher (the fourth corps of this army fought at the Battle of Wavre on the same day). The battle marked the end of the Napoleonic Wars. The battle was contemporaneously known as the Battle of Mont Saint-J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Design
A design is a plan or specification for the construction of an object or system or for the implementation of an activity or process or the result of that plan or specification in the form of a prototype, product, or process. The verb ''to design'' expresses the process of developing a design. In some cases, the direct construction of an object without an explicit prior plan (such as in craftwork, some engineering, coding, and graphic design) may also be considered to be a design activity. The design usually has to satisfy certain goals and constraints; may take into account aesthetic, functional, economic, or socio-political considerations; and is expected to interact with a certain Environment (systems), environment. Typical examples of designs include architectural drawing, architectural and engineering drawing, engineering drawings, circuit diagrams, Pattern (sewing), sewing patterns and less tangible artefacts such as business process models.

Colours
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance. Color science includes the perception of color by the eye and brain, the origin of color in materials, color theory in art, and the physics of electromag ...

Gas Light
''Gas Light'' is a 1938 thriller play, set in the Victorian era, written by the British novelist and playwright Patrick Hamilton. Hamilton's play is a dark tale of a marriage based on deceit and trickery, and a husband committed to driving his wife insane in order to steal from her. ''Gas Light'' was written during a dark period in Hamilton's life. Six years prior to the play Hamilton was hit by a drunk driver and dragged through the streets of London, leaving him with a limp, a paralyzed arm, and a disfigured face. Two years later, Hamilton's mother committed suicide. Premiering at the Richmond Theatre in London on 5 December 1938 before transferring to the Apollo Theatre in the West End on 1 January, the play closed after six months and 141 performances, but it has endured through an impressive list of incarnations most notably ''Five Chelsea Lane'' (1941 American play), ''Angel Street'' (1941 American play), and ''Gaslight'' (1958 Australian television play).

Streetlights
A street light, light pole, lamp pole, lamppost, street lamp, light standard, or lamp standard is a raised source of light on the edge of a road or path. Similar lights may be found on a railway platform. When urban electric power distribution became ubiquitous in developed countries in the 20th century, lights for urban streets followed, or sometimes led. Many lamps have light-sensitive photocells that activate the lamp automatically when needed, at times when there is little-to-no ambient light, such as at dusk, dawn, or at the onset of dark weather conditions. This function in older lighting systems could be performed with the aid of a solar dial. Many street light systems are being connected underground instead of wiring from one utility post to another. Street lights are an important source of public security lighting intended to reduce crime. History Preindustrial era Early lamps were used by Greek and Roman civilizations, where light primarily served the purpose of ...

Gas Lighting
Gas lighting is the production of artificial light from combustion of a gaseous fuel, such as hydrogen, methane, carbon monoxide, propane, butane, acetylene, ethylene, coal gas (town gas) or natural gas. The light is produced either directly by the flame, generally by using special mixes (typically propane or butane) of illuminating gas to increase brightness, or indirectly with other components such as the gas mantle or the limelight, with the gas primarily functioning as a heat source for the incandescence of the gas mantle or lime. Before electricity became sufficiently widespread and economical to allow for general public use, gas was the most prevalent method of outdoor and indoor lighting in cities and suburbs, areas where the infrastructure for distribution of the gaseous fuel was practical. When gas lighting was prevalent, the most common fuels for gas lighting were wood gas, coal gas and, in limited cases, water gas. Early gas lights were ignited manually by lampl ...

Theory Of Colours
''Theory of Colours'' (german: Zur Farbenlehre, links=no) is a book by Johann Wolfgang von Goethe about the poet's views on the nature of colours and how these are perceived by humans. It was published in German in 1810 and in English in 1840. The book contains detailed descriptions of phenomena such as coloured shadows, refraction, and chromatic aberration. The work originated in Goethe's occupation with painting and mainly exerted an influence on the arts (Philipp Otto Runge, J. M. W. Turner, the Pre-Raphaelites, Hilma af Klint, Wassily Kandinsky). The book is a successor to two short essays entitled "Contributions to Optics". Although Goethe's work was rejected by some physicists, a number of philosophers and physicists have concerned themselves with it, including Thomas Johann Seebeck, Arthur Schopenhauer (see: '' On Vision and Colors''), Hermann von Helmholtz, Ludwig Wittgenstein, Werner Heisenberg, Kurt Gödel, and Mitchell Feigenbaum.
