Norwood's Arc Measurement
Richard Norwood (1590? – 1675) was an English mathematician, diver, and surveyor. He has been called "Bermuda’s outstanding genius of the seventeenth century". Life Born about 1590, he was in 1616 sent out by the Somers Isles Company to survey the islands of Bermuda (also known as the Somers Isles), then newly settled. He was later accused of collusion with the governor, and that, after assigning the shares to all the settlers, eight shares of the best land remained over, for the personal advantage of himself and the governor. His map was published in London in 1622. In 1623, Norwood patented lands in Virginia, but it does not appear that he ever went there. He is said to have resided at that date in the Bermudas. He may have made several visits to the islands, but according to his own statements he was, for some years before 1630 and after, up to 1640, resident in London, near Tower Hill, as a teacher of mathematics. He is also credited with founding Bermuda's oldest school, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagoreans, Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathemat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arc Measurement
Arc measurement, sometimes degree measurement (german: Gradmessung), is the astrogeodetic technique of determining of the radius of Earth – more specifically, the local Earth radius of curvature of the figure of the Earth – by relating the latitude difference (sometimes also the longitude difference) and the geographic distance (arc length) surveyed between two locations on Earth's surface. The most common variant involves only astronomical latitudes and the meridian arc length and is called ''meridian arc measurement''; other variants may involve only astronomical longitude ('' parallel arc measurement'') or both geographic coordinates (''oblique arc measurement''). Arc measurement campaigns in Europe were the precursors to the International Association of Geodesy (IAG). History The first known arc measurement was performed by Eratosthenes (240 BC) between Alexandria and Syene in what is now Egypt, determining the radius of the Earth with remarkable correctness.

Events January–March * January 5 – Franco-Dutch War – Battle of Turckheim: The French defeat Austria and Brandenburg. * January 29 – John Sassamon, an English-educated Native American Christian, dies at Assawampsett Pond, an event which will trigger a year-long war between the English American colonists of New England, and the Algonquian Native American tribes. * February 4 – The Italian opera ''La divisione del mondo'', by Giovanni Legrenzi, is performed for the first time, premiering in Venice at the Teatro San Luca. The new opera, telling the story of the "division of the world" after the battle between the Gods of Olympus and the Titans, becomes known for its elaborate and expensive sets, machinery, and special effects and is revived 325 years later in the year 2000. * February 6 – Nicolò Sagredo is elected as the new Doge of Venice and leader of the Venetian Republic, replacing Domenico II Contarini, who had died 10 days ...

Year 159 ( CLIX) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time in Roman territories, it was known as the Year of the Consulship of Quintillus and Priscus (or, less frequently, year 912 ''Ab urbe condita''). The denomination 159 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Sandwich, Kent
Sandwich is a town and civil parish in the Dover District of Kent, south-east England. It lies on the River Stour and has a population of 4,985.

While once a major port, it is now two miles from the sea due to the disappearance of the Wantsum Channel. Its historic centre has been preserved. Sandwich Bay is home to nature reserves and two world-class golf courses, Royal St George's and Prince's. The town is also home to many educational and cultural events. Sandwich also gave its name to the food by way of John Montagu, 4th Earl of Sandwich, and the word ''sandwich'' is now found in several languages.
