Pyrophone (2v)
A pyrophone, also known as a "fire/explosion organ" or "fire/explosion calliope" is a musical instrument in which notes are sounded by explosions, or similar forms of rapid combustion, rapid heating, or the like, such as burners in cylindrical glass tubes, creating light and sound. It was invented by physicist and musician Georges Frédéric Eugène Kastner (born 1852 in Strasbourg, France - died 1882 in Bonn, Germany), son of composer Jean-Georges Kastner, around 1870. Design Related musical instruments The pyrophone is similar to the steam calliope, but the difference is that in the calliope the combustion is external to the resonant cavity, whereas the pyrophone is an internal combustion instrument. The difference initially seems insignificant, but external combustion is what gives the calliope its staccato. Operating under the constant pressures of an external combustion chamber, the calliope merely directs exhaust ( HB# 421.22: internal fipple flutes). By control ...

Spark Plug
A spark plug (sometimes, in British English, a sparking plug, and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a ceramic insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded. The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the ' ...

Gasoline
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades. Tetraethyl lea ...

Propane
Propane () is a three-carbon alkane with the molecular formula . 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 commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation. Discovered in 1857 by the French chemist Marcellin Berthelot, it became commercially available in the US by 1911. Propane is one of a group of liquefied petroleum gases (LP gases). The others include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof. Propane has lower volumetric energy density, but higher gravimetric energy density and burns more cleanly than gasoline and coal. 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 (2 phases). Propane powers buses, forklifts, taxis, outboard boat motors, and ...

Wendelin Weißheimer
Wendelin Weißheimer (26 February 1838 – 16 June 1910) was a German composer, conductor, essayist, teacher, and writer on music. He studied with Franz Liszt and was in close contact with Richard Wagner, Hans von Bülow, Peter Cornelius, Louise Otto-Peters, Ferdinand Lassalle, August Bebel and many other notable musicians of his time. He served as composer and conductor of choirs in Mainz, Darmstadt, Baden-Baden, Würzburg, Munich, Leipzig, Berlin, Düsseldorf, Szczecin, Strasbourg and at Milan's La Scala. Early life Origin, family and childhood The Weißheimer family resided in Westhofen in the 14th century. Wendelin's grandfather, Johann Weißheimer I, from Osthofen, inherited a stone mill from his mother's family at the end of the 18th century. Viticulture, agriculture, animal husbandry and mill grinding were already undertaken on the manor complex in the 19th century. The manor is still owned by the Weißheimer family. This complex was one of the most important in the f ...

Henry Dunant
Henry Dunant (born Jean-Henri Dunant; 8 May 182830 October 1910), also known as Henri Dunant, was a Swiss humanitarian, businessman, and social activist. He was the visionary, promoter, and co-founder of the Red Cross. In 1901, he received the first Nobel Peace Prize together with Frédéric Passy. Dunant was the first Swiss Nobel laureate. In 1859, Dunant was witness to the aftermath of the Battle of Solferino in Italy. He recorded his memories and experiences in the book '' A Memory of Solferino'' which inspired the creation of the International Committee of the Red Cross (ICRC) in 1863. The 1864 Geneva Convention was based on Dunant's idea for an independent organization to care for wounded soldiers. Dunant was the founder of the Swiss branch of the YMCA. Early life and education Dunant was born in Geneva, Switzerland, in 1828 as the first son of businessman Jean-Jacques Dunant and Antoinette Dunant-Colladon. His family was devoutly Calvinist and had significant infl ...

Exposition Universelle (1878)
The third Paris World's Fair, called an Exposition Universelle in French, was held from 1 May to 10 November 1878. It celebrated the recovery of France after the 1870–71 Franco-Prussian War. Construction The buildings and the fairgrounds were somewhat unfinished on opening day, as political complications had prevented the French government from paying much attention to the exhibition until six months before it was due to open. However, efforts made in April were prodigious, and by 1 June, a month after the formal opening, the exhibition was finally completed. This exposition was on a far larger scale than any previously held anywhere in the world. It covered over , the main building in the Champ de Mars and the hill of Chaillot, occupying . The Gare du Champ de Mars was rebuilt with four tracks to receive rail traffic occasioned by the exposition. The Pont d'Iéna linked the two exhibition sites along the central allée. The French exhibits filled one-half of the enti ...

Charles Gounod
Charles-François Gounod (; ; 17 June 181818 October 1893), usually known as Charles Gounod, was a French composer. He wrote twelve operas, of which the most popular has always been ''Faust (opera), Faust'' (1859); his ''Roméo et Juliette'' (1867) also remains in the international repertory. He composed a large amount of church music, many songs, and popular short pieces including his Ave Maria (Bach/Gounod), Ave Maria (an elaboration of a Johann Sebastian Bach, Bach piece), and ''Funeral March of a Marionette''. Born in Paris into an artistic and musical family Gounod was a student at the Conservatoire de Paris and won France's most prestigious musical prize, the Prix de Rome. His studies took him to Italy, Austria and then Prussia, where he met Felix Mendelssohn, whose advocacy of the music of Bach was an early influence on him. He was deeply religious, and after his return to Paris, he briefly considered becoming a priest. He composed prolifically, writing church music, songs ...

Harmonic Series (music)
A harmonic series (also overtone series) is the sequence of harmonics, musical tones, or pure tones whose frequency is an integer multiple of a ''fundamental frequency''. Pitched musical instruments are often based on an acoustic resonator such as a string or a column of air, which oscillates at numerous modes simultaneously. At the frequencies of each vibrating mode, waves travel in both directions along the string or air column, reinforcing and canceling each other to form standing waves. Interaction with the surrounding air causes audible sound waves, which travel away from the instrument. Because of the typical spacing of the resonances, these frequencies are mostly limited to integer multiples, or harmonics, of the lowest frequency, and such multiples form the harmonic series. The musical pitch of a note is usually perceived as the lowest partial present (the fundamental frequency), which may be the one created by vibration over the full length of the string or air c ...
