John Stone Stone (September 24, 1869 – May 20, 1943) was an American mathematician, physicist and inventor. He initially worked in telephone research, followed by influential work developing early radio technology, where he was especially known for improvements in tuning. Despite his often advanced designs, the Stone Telegraph and Telephone Company failed in 1908, and he spent the remainder of his career as an engineering consultant. Biography Early years Stone was born in Dover (now Manakin) village, in Goochland County, Virginia, the son of Charles Pomeroy Stone, an American Civil War Union general and engineer, and Annie Jeannie toneStone. From 1870 until 1883, General Stone held the post of Chief of Staff to the khedive of Egypt, and, while growing up in Cairo, John Stone Stone became fluent in Arabic, French, German and Spanish in addition to English.

Manakin-Sabot, Virginia
Manakin-Sabot, consisting of the villages of Manakin and Sabot, is an unincorporated community in Goochland County, Virginia, United States. It is located northwest of Richmond in the Piedmont and is part of the Greater Richmond region. History Among the earliest European settlers in the Piedmont were several hundred French Huguenots, Protestant religious refugees who had emigrated via London in 1700 and 1701 on the promise of land from the Crown. While they had expected to be settled near existing settlements of Jamestown or in Lower Norfolk County, officials gave them land in areas 20 miles above the falls of the James River at areas previously occupied by the Native American Monacan people. This tribe spoke a Siouan language, as did other tribes of the uplands. One French settlement in Powhatan County became known as Manakin Town (after the native tribe); two villages in Goochland were Manakin and Sabot. The colony of Manakin was created by a grant of 10,000 acres of land in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alpha Delta Phi
Alpha Delta Phi (), commonly known as Alpha Delt, ADPhi, A-Delt, or ADP, is a North American Greek-letter social college fraternity. Alpha Delta Phi was originally founded as a literary society by Samuel Eells in 1832 at Hamilton College in Clinton, New York. Its more than 50,000 alumni include former presidents and senators of the United States, and justices of the Supreme Court. The mission of the Alpha Delta Phi Fraternity is to provide a comprehensive and positive personal growth experience for all undergraduate and alumni brothers: social, ethical, leadership, scholastic, community service, and literary. Founding When Samuel Eells arrived on campus at Hamilton College, he found two existing literary societies, the Phoenix and the Philopeuthian, the latter of which he reluctantly joined. Eells quickly became disenchanted with both societies' unscrupulous recruiting tactics and dispassionately small sizes and considered creating his own society which would disavow wha ...

Audion
The Audion was an electronic detecting or amplifying vacuum tube invented by American electrical engineer Lee de Forest in 1906.De Forest patented a number of variations of his detector tubes starting in 1906. The patent that most clearly covers the Audion is , Space Telegraphy', filed January 29, 1907, issued February 18, 1908 The link is to a reprint of the paper in the ''Scientific American Supplement'', Nos. 1665 and 1666, November 30, 1907 and December 7, 1907, p.348-350 and 354-356. It was the first triode, consisting of an evacuated glass tube containing three electrodes: a heated filament, a grid, and a plate. It is important in the history of technology because it was the first widely used electronic device which could amplify. A low power signal at the grid could control much more power in the plate circuit. Audions had more residual gas than later vacuum tubes; the residual gas limited the dynamic range and gave the Audion non-linear characteristics and erratic per ...
