Lee De Forest
Lee de Forest (August 26, 1873 – June 30, 1961) was an American inventor and a fundamentally important early pioneer in electronics. He invented the first electronic device for controlling current flow; the three-element " Audion" triode vacuum tube in 1906. This started the Electronic Age, and enabled the development of the electronic amplifier and oscillator. These made radio broadcasting and long distance telephone lines possible, and led to the development of talking motion pictures, among countless other applications. He had over 300 patents worldwide, but also a tumultuous career— he boasted that he made, then lost, four fortunes. He was also involved in several major patent lawsuits, spent a substantial part of his income on legal bills, and was even tried (and acquitted) for mail fraud. Despite this, he was recognised for his pioneering work with the 1922 IEEE Medal of Honor, the 1923 Franklin Institute Elliott Cresson Medal and the 1946 American Institute of ...

Council Bluffs, Iowa
Council Bluffs is a city in and the county seat of Pottawattamie County, Iowa, United States. The city is the most populous in Southwest Iowa, and is the third largest and a primary city of the Omaha-Council Bluffs Metropolitan Area. It is located on the east bank of the Missouri River, across from the city of Omaha, Nebraska. Council Bluffs was known, until at least 1853, as Kanesville. It was the historic starting point of the Mormon Trail. Kanesville is also the northernmost anchor town of the other emigrant trails, since there was a steam-powered boat to ferry their wagons, and cattle, across the Missouri River. In 1869, the first transcontinental railroad to California was connected to the existing U.S. rail network at Council Bluffs. Council Bluffs' population was 62,799 at the time of the 2020 census, making it the state's tenth largest city. The Omaha metropolitan region, of which Council Bluffs is a part, is the 58th largest in the United States, with an estimat ...

Oscillator
Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples of oscillation include a swinging pendulum and alternating current. Oscillations can be used in physics to approximate complex interactions, such as those between atoms. Oscillations occur not only in mechanical systems but also in dynamic systems in virtually every area of science: for example the beating of the human heart (for circulation), business cycles in economics, predator–prey population cycles in ecology, geothermal geysers in geology, vibration of strings in guitar and other string instruments, periodic firing of nerve cells in the brain, and the periodic swelling of Cepheid variable stars in astronomy. The term ''vibration'' is precisely used to describe a mechanical oscillation. Oscillation, especially rapid oscillation, may be an undesirable phenomenon in p ...

Talladega College
Talladega College is a private historically black college in Talladega, Alabama. It is Alabama's oldest private historically black college and offers 17 degree programs. It is accredited by the Southern Association of Colleges and Schools. History The history of Talladega College began on November 20, 1865, when three former slaves William Savery, Thomas Tarrant, and Ambrose Headen of Talladega, met in convention with a group of new freedmen in Mobile, Alabama. From this meeting came the commitment, "We regard the education of our children and youth as vital to the preservation of our liberties, and true religion as the foundation of all real virtue, and shall use our utmost endeavors to promote these blessings in our common country." With this as their pledge, Savery, Tarrant, and Headen aided by General Wager Swayne of the Freedmen's Bureau, began in earnest to provide a school for the children of former slaves of the community. Their leadership resulted in the construction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Congregational Church
Congregational churches (also Congregationalist churches or Congregationalism) are Protestant churches in the Calvinist tradition practising congregationalist church governance, in which each congregation independently and autonomously runs its own affairs. Congregationalism, as defined by the Pew Research Center, is estimated to represent 0.5 percent of the worldwide Protestant population; though their organizational customs and other ideas influenced significant parts of Protestantism, as well as other Christian congregations. The report defines it very narrowly, encompassing mainly denominations in the United States and the United Kingdom, which can trace their history back to nonconforming Protestants, Puritans, Separatists, Independents, English religious groups coming out of the English Civil War, and other English Dissenters not satisfied with the degree to which the Church of England had been reformed. Congregationalist tradition has a presence in the United States ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huguenots
The Huguenots ( , also , ) were a religious group of French Protestants who held to the Reformed, or Calvinist, tradition of Protestantism. The term, which may be derived from the name of a Swiss political leader, the Genevan burgomaster Bezanson Hugues (1491–1532?), was in common use by the mid-16th century. ''Huguenot'' was frequently used in reference to those of the Reformed Church of France from the time of the Protestant Reformation. By contrast, the Protestant populations of eastern France, in Alsace, Moselle, and Montbéliard, were mainly Lutherans. In his ''Encyclopedia of Protestantism'', Hans Hillerbrand wrote that on the eve of the St. Bartholomew's Day massacre in 1572, the Huguenot community made up as much as 10% of the French population. By 1600, it had declined to 7–8%, and was reduced further late in the century after the return of persecution under Louis XIV, who instituted the '' dragonnades'' to forcibly convert Protestants, and then finally revoke ...

Walloons
Walloons (; french: Wallons ; wa, Walons) are a Gallo-Romance ethnic group living native to Wallonia and the immediate adjacent regions of France. Walloons primarily speak '' langues d'oïl'' such as Belgian French, Picard and Walloon. Walloons are historically and primarily Roman Catholic. In modern Belgium, Walloons are, by law, termed a "distinctive linguistic and ethnic community" within the country, as are the neighbouring Flemish, a Germanic group. When understood as a regional identification, the ethnonym is also extended to refer to the inhabitants of the Walloon region in general, regardless of ethnicity or ancestry. Etymology The term ''Walloon'' is derived from ''* walha'', a Proto-Germanic term used to refer to Celtic and Latin speakers. ''Walloon'' originated in Romance languages alongside other related terms, but it supplanted them. Its oldest written trace is found in Jean de Haynin's ''Mémoires de Jean, sire de Haynin et de Louvignies'' in 1465, where ...

Jessé De Forest
Jessé de Forest (1576 – October 22, 1624) was the leader of a group of Walloon Huguenots who fled Europe due to religious persecutions. They emigrated to the New World, where he planned to found New-Amsterdam, which is currently New York City. Background Jessé de Forest was born between the dates of 1576 and 1578 in Avesnes (County of Hainaut, now Nord, France). The family name originated from the village of Forest in the canton of Landrecies near Avesnes. (A ''Sports Illustrated'' article incorrectly claims that Jessé was a son of the French king Henri IV.) Around 1609 he left Avesnes for Sedan and Montcornet before settling in Leiden, the Netherlands. In Leiden, he moved to obtain the right to emigrate with his own and other Walloon families to the New World. During his stay, he also met Pilgrim Fathers, future passengers of the ''Mayflower''. De Forest served with Prince Maurice of Nassau as a lieutenant and captain. On February 5, 1621, Jessé de Forest sent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
