Light's Golden Jubilee
Light's Golden Jubilee was a celebration of the 50th anniversary of Thomas Edison's incandescent light bulb, held on October 21, 1929, just days before the stock market crash of 1929 that swept the United States headlong into the Great Depression. The Jubilee also served as the dedication of Henry Ford's Greenfield Village, originally known as the Thomas Edison Institute. Origins A golden jubilee marks the 50th anniversary of events, people, and things. Originally, "Light’s Golden Jubilee" was a celebration organized by the General Electric Company, which had absorbed Edison's original business and saw great business value in drawing connections between itself and the illustrious inventor. Thomas Edison and his family, however, believed that the aging inventor was being used and appealed to Henry Ford, Edison's long-time friend. Eventually, the celebration turned into a collaboration between Henry Ford and General Electric, though Ford won control over much of the ceremony, ...

Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

Horseless Carriage
Horseless carriage is an early name for the car, motor car or automobile. Prior to the invention of the motor car, carriages were usually pulled by animals, typically horses. The term can be compared to other transitional terms, such as mobile phone, wireless phone. These are cases in which a new technology is compared to an older one by describing what the new one does not have. Most horseless carriages are notable for their similarity to existing horse-drawn carriages, but with some type of mechanical propulsion. Features of the first horseless carriages include tiller steering, an engine under the floorboards, and a high center of gravity. In the 19th century, steam engines became the primary source of power for railway locomotives and ships, and for powering processes in fixed installations such as factory, factories. In 1803, what is said to have been the first horseless carriage was a steam-driven vehicle demonstrated in London, England, by Richard Trevithick. In the 1820s, ...

Albert Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ' ...

Charles M
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man".

The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its dep ...
