Isaac Newton
Sir Isaac Newton (25 December 1642 – 20 March 1726/27) was an English mathematician, physicist, astronomer, alchemist, theologian, and author (described in his time as a "natural philosopher"), widely recognised as one of the greatest mathematicians and physicists and among the most influential scientists of all time. He was a key figure in the philosophical revolution known as the Enlightenment. His book (''Mathematical Principles of Natural Philosophy''), first published in 1687, established classical mechanics. Newton also made seminal contributions to optics, and shares credit with German mathematician Gottfried Wilhelm Leibniz for developing infinitesimal calculus. In the , Newton formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint for centuries until it was superseded by the theory of relativity. Newton used his mathematical description of gravity to derive Kepler's laws of planetary motion, account for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Province Of Maryland
The Province of Maryland was an English and later British colony in North America that existed from 1632 until 1776, when it joined the other twelve of the Thirteen Colonies in rebellion against Great Britain and became the U.S. state of Maryland. Its first settlement and capital was St. Mary's City, in the southern end of St. Mary's County, which is a peninsula in the Chesapeake Bay and is also bordered by four tidal rivers. The province began as a proprietary colony of the English Lord Baltimore, who wished to create a haven for English Catholics in the New World at the time of the European wars of religion. Although Maryland was an early pioneer of religious toleration in the English colonies, religious strife among Anglicans, Puritans, Catholics, and Quakers was common in the early years, and Puritan rebels briefly seized control of the province. In 1689, the year following the Glorious Revolution, John Coode led a rebellion that removed Lord Baltimore, a Catholic, from pow ...

Tobacco
Tobacco is the common name of several plants in the genus '' Nicotiana'' of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is ''N. tabacum''. The more potent variant ''N. rustica'' is also used in some countries. Dried tobacco leaves are mainly used for smoking in cigarettes and cigars, as well as pipes and shishas. They can also be consumed as snuff, chewing tobacco, dipping tobacco, and snus. Tobacco contains the highly addictive stimulant alkaloid nicotine as well as harmala alkaloids. Tobacco use is a cause or risk factor for many deadly diseases, especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco use as the world's single greatest preventable cause of death. Etymology The English word ''tobacco'' originates from the Spanish word "tabaco ...

South River Club
The South River Club is a social club located just south of Annapolis in Anne Arundel County, Maryland. The name also refers to the group's clubhouse, which was built in 1742. The club The South River Club (also known as "The Old South River Club") is one of the country's oldest, continuously active organizations of its type. Early records were lost when the first clubhouse burned down, but there is evidence that the club existed in 1732 and perhaps as early as 1700. Club records show that it existed before February 11, 1742, when a resolution was passed to attempt to record all previous members' names. As early as 1746, the club was referred to as "The Ancient South River Club" in the ''Maryland Gazette.'' Early members included prominent landowners, merchants, and the local doctor and clergyman, all of whom lived within a 10-mile radius of the clubhouse. The members of the club meet at the clubhouse four times per year for feasts prepared in the detached kitchen. Women are onl ...

Lewis Evans (surveyor)
Lewis Evans (c. 170012 June 1756) was a Welsh surveyor and geographer. He had a brother John. In the mid-1730s he emigrated to British America, where he was based in Philadelphia. He was well known for his 1755 map of the Middle British Colonies. Biography Lewis Evans was born in Caernarfonshire, Wales. He travelled to the British colonies in North America, where he settled in Philadelphia by the mid-1730s. In 1736 he bought a book from Benjamin Franklin, a printer, which was the start of their friendship. Franklin encouraged his geographic and scientific research. In 1743 Evans married Martha Hoskins, a friend of Franklin's wife Deborah Read Franklin. They had a daughter Amelia before Martha died in 1754, when the girl was ten.

Ebenezer Kinnersley
Ebenezer Kinnersley (30 November 1711 – 4 July 1778]) was an English scientist, inventor and lecturer, specializing in the investigation of electricity. Life and Scientific Studies Ebenezer Kinnersley was a son of Rev. William Kinnersley, an assistant pastor of the Lower Dublin Baptist church. Ebenezer became a member of this church while young, and in 1743 was ordained as a minister, but he never served as a pastor. He travelled to America with his parents in 1714. His early life was passed at Dublin, and then he went to Philadelphia, where he gave evidence of his genius as a scholar and mechanician. It is supposed that he taught a school there and associated with Benjamin Franklin, who soon learned to appreciate young Kinnersley, whom he designates as "an ingenious neighbor." When Franklin saw Dr Spence, a Scotsman in Boston, experiment with a glass tube and silk, and observed the effects that were produced, he communicated the fact to his associates in Philadelphia, and ...

Mentor
Mentorship is the influence, guidance, or direction given by a mentor. A mentor is someone who teaches or gives help and advice to a less experienced and often younger person. In an organizational setting, a mentor influences the personal and professional growth of a mentee. Most traditional mentorships involve having senior employees mentor more junior employees, but mentors do not necessarily have to be more senior than the people they mentor. What matters is that mentors have experience that others can learn from. According to the Business Dictionary, a mentor is a senior or more experienced person who is assigned to function as an advisor, counsellor, or guide to a junior or trainee. The mentor is responsible for offering help and feedback to the person under their supervision. A mentor's role, according to this definition, is to use their experience to help a junior employee by supporting them in their work and career, providing comments on their work, and, most crucially, ...

Static Electricity
Static electricity is an imbalance of electric charges within or on the surface of a material or between materials. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, where the electric charge flows through an electrical conductor or space, and transmits energy. A static electric charge can be created whenever two surfaces contact and have worn and separated, and at least one of the surfaces has a high resistance to electric current (and is therefore an electrical insulator). The effects of static electricity are familiar to most people because people can feel, hear, and even see the spark as the excess charge is neutralized when brought close to a large electrical conductor (for example, a path to ground), or a region with an excess charge of the opposite polarity (positive or negative). The familiar phenomenon of a static shockmore specifically, an electros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pieter Van Musschenbroek
Pieter van Musschenbroek (14 March 1692 – 19 September 1761) was a Dutch scientist. He was a professor in Duisburg, Utrecht, and Leiden, where he held positions in mathematics, philosophy, medicine, and astronomy. He is credited with the invention of the first capacitor in 1746: the Leyden jar. He performed pioneering work on the buckling of compressed struts. Musschenbroek was also one of the first scientists (1729) to provide detailed descriptions of testing machines for tension, compression, and flexure testing. An early example of a problem in dynamic plasticity was described in the 1739 paper (in the form of the penetration of butter by a wooden stick subjected to impact by a wooden sphere). Early life and studies Pieter van Musschenbroek was born on 14 March 1692 in Leiden, Holland, Dutch Republic. His father was Johannes van Musschenbroek and his mother was Margaretha van Straaten.
