 Upper Volta - Wikipedia, the free encyclopedia
The French colony of Upper Volta was established on March 1, 1919 with its current boundaries from what had been administered as part of Côte d'Ivoire colony.
However, on September 5, 1932, Upper Volta was broken apart, with parts being administered by the colonies of Côte d’Ivoire, French Sudan (present day Mali), and Niger.
The colony was revived with the previous boundaries on September 4, 1947.

 CATHOLIC ENCYCLOPEDIA: Alessandro Volta
In seeking further experimental evidence in favour of his contact theory, Volta was led to the greatest of his inventions, the voltaic "pile", which he described in a communication of 20 March, 1800, to Sir Joseph Banks, President of the Royal Society of London.
The voltaic battery of 1800 marks an epoch in physical theory as well as in the application of science to the welfare of mankind.
In the summer of 1899, the centenary of the invention of the voltaic battery, an exposition was held in Como of electrical apparatus constructed and used by Volta in his investigations, but unfortunately a fire broke out and many of these heirlooms of science were destroyed.

Volta clarified the concept of electrical tension (or, in modern parlance, voltage); formulated the mathematical relation between quantity of charge, tension and capacity; introduced the concepts of contact "potential" and of electromotive force; and came very close to formulating quantitatively the relations between tension, resistance and current.
Volta's role as hero in the industrial era prompts Pancaldi to criticize the use of past science to serve local interests, local pride and local ambitions, as occurred when two residents of Como, a fascist and a silk industrialist, organized the 1927 celebrations there, using Volta to call attention to the town.
Volta's best qualities as an investigator were the result of adjustment between his aspirations as a natural philosopher and the more modest role of inventor of intriguing machines that sections of the community of electricians came to assign him.

 IEEE History Center - Volta's Electrical Battery Invention, 1799
Volta's development of the first continuous and reproducible source of electrical current was an important step in the study of electromagnetism and in the development of electrical equipment.
He built a battery, known as a Voltaic pile, made of alternating copper and zinc discs, with each pair of metals separated by flannel soaked in weak acid.
The Voltaic pile stimulated so much scientific inquiry that, by 1831, when Faraday built the first dynamo, the basic principles of electricity had been established.

Alessandro Giuseppe Antonio Anastasio Volta (1745-1827) was the great antagonist of Galvani, and his efforts to refute the theory of animal electricity later resulted in his invention of the voltaic pile, the first electric battery.
According to Volta's interpretation, the muscle twitches were induced by current flowing between two dissimilar metals connected by the moist flesh of the frog's leg.
This stack became known as the voltaic pile and was the progenitor for modern alkaline batteries.

 Alessandro Volta: The Voltaic Pile Experiment - The Invention of the Battery
with Galvani's theory of animal electricity that led Volta, in 1800, to build the voltaic pile to prove that electricity did not come from the animal tissue but was generated by the contact of different metals in a moist environment.
Most historians attribute the invention of the battery to Alessandro Volta since his voltaic pile was the first battery that produced a reliable, steady current of electricity.
Volta found that this wet stack of “dissimilar metals” created a small electric current, and this current could be drawn off through wires and used for experiments.

 StreetSwing's Dance History Archives - La Volta Dance Page - Main1
The Volta (Vuel-ta) is known as a "Renaissance dance" (a period in time) which came from Italy (some say Provence, France) as a peasant dance in the early 16th century and later into Switzerland, then to France (Volte) and ending in Germany.
The Volta is said to be the first of the Waltzes or the forerunner of the Waltz when combined with other round dances.
It was reported that "the Volta brought forth many murders and miscarriages" (not true) and "should be heavily looked into by local police." Madame de Valentinois, in the time of Francis the First, was very fond of this dance, and while dancing it sang the psalms translated by Clement Marot.

 Volta
First edition, rare offprint form, of this major work of Volta, in which he established that Galvani's 'animal electricity' was in fact the result of contact of two different metals in a conductive environment and that the muscle spasms observed by Galvani were the result of purely external electrical stimulation.
Volta had been one of the first to take up Galvani's theory of animal electricity but he became skeptical as his own research progressed, finally concluding that all galvanic excitations were the result of external electrical stimulation produced by the contact of two dissimilar metals in a moist environment.
Among the experiments described is the following: Four insulated individuals form a human chain, the first placing his finger on the tip of the second's tongue, the second likewise touching the uncovered eyeball of the third, and the third and fourth holding between them in their wet hands a freshly skinned and gutted frog.

The lake is formed by the Akosombo Dam (q.v.), which, begun in 1961 and completed in 1965, dammed the Volta River just south of Ajena and created a lake extending upstream from the Akosombo Dam to Yapei, beyond the former confluence of the Black Volta and White Volta rivers.
It rises 16 miles (26 km) northwest of Mampong and flows southeast into Lake Volta (formerly the Afram was a tributary of the Volta River).
The Volta Basin, a vast saucer-shaped plateau averaging from 990 to 1,980 feet (300 to 600 meters) above sea level, occupies the north-central part of the country.

 Volta'sPile   (Site not responding. Last check: 2007-11-07)
Above is a diagram of a reconceptualization of one of Volta's early experiments.
This experiment is like one that Volta did around 1800 in order to test his hypothesis that two different kinds of metal could produce electricity, thus explaining what caused the legs of dead frogs to twitch on Galvani's lab table (see our historical background).
If the needle on the voltmeter moves to the right from its zero mark on the left, then the experiment supports Volta's hypothesis that two different kinds of metal can be made to produce an electrical current.
