Adriaan Anthonisz
Adriaan Anthonisz (also known as Adriaen Anthonisz of Alcmaer) (1527–1607) was a Dutch mathematician, surveyor, cartographer, and military engineer who specialized in the design of fortifications. As a mathematician Anthonisz calculated in 1585 the ratio of a circle's circumference to its diameter, which would later be called pi. Life Anthonisz served as burgomaster (mayor) of Alkmaar in the Netherlands from 1582. Adriaan fathered two sons, and named them both Metius (from the Dutch word ''meten'', meaning 'measuring', 'measurer', or surveyor). They each became prominent members of society. Adriaan Metius (9 Dec 1571 – 6 Sep 1635) was a Dutch geometer and astronomer. Jacob Metius worked as an instrument-maker and a specialist in grinding lenses and applied for patent rights for the telescope a few weeks after Middelburg spectacle-maker Hans Lippershey tried to patent the same device. Career In 1585 Anthonisz discovered that the ratio of a circle's circumference to its diam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mr Adriaan Anthonisz John Bier Noorderkade Alkmaar
''Mister'', usually written in its contracted form ''Mr.'' or ''Mr'', is a commonly used English honorific for men without a higher honorific, or professional title, or any of various designations of office. The title 'Mr' derived from earlier forms of ''Master (form of address), master'', as the equivalent female titles ''Mrs., Mrs'', ''Miss'', and ''Ms., Ms'' all derived from earlier forms of ''Mistress (form of address), mistress''. ''Master'' is sometimes still used as an honorific for boys and young men. The modern plural form is ''Misters'', although its usual formal abbreviation ''Messrs''(.) derives from use of the French title ' in the 18th century. ' is the plural of ' (originally ', "my lord"), formed by declension (nouns), declining both of its constituent parts separately. Historical etiquette Historically, ''mister'' was applied only to those above one's own status if they had no higher title such as ''Sir'' or ''my lord'' in the English class system. That unders ...

Milü
Milü (; "close ratio"), also known as Zulü ( Zu's ratio), is the name given to an approximation to (pi) found by Chinese mathematician and astronomer Zu Chongzhi in the 5th century. Using Liu Hui's algorithm (which is based on the areas of regular polygons approximating a circle), Zu famously computed to be between 3.1415926 and 3.1415927 and gave two rational approximations of , and , naming them respectively Yuelü (; "approximate ratio") and Milü. is the best rational approximation of with a denominator of four digits or fewer, being accurate to six decimal places. It is within % of the value of , or in terms of common fractions overestimates by less than . The next rational number (ordered by size of denominator) that is a better rational approximation of is , still only correct to six decimal places and hardly closer to than . To be accurate to seven decimal places, one needs to go as far as . For eight, is needed. The accuracy of Milü to the true value of ...

16th-century Dutch Military Personnel
The 16th century begins with the Julian year 1501 ( MDI) and ends with either the Julian or the Gregorian year 1600 ( MDC) (depending on the reckoning used; the Gregorian calendar introduced a lapse of 10 days in October 1582). The 16th century is regarded by historians as the century which saw the rise of Western civilization and the Islamic gunpowder empires. The Renaissance in Italy and Europe saw the emergence of important artists, authors and scientists, and led to the foundation of important subjects which include accounting and political science. Copernicus proposed the heliocentric universe, which was met with strong resistance, and Tycho Brahe refuted the theory of celestial spheres through observational measurement of the 1572 appearance of a Milky Way supernova. These events directly challenged the long-held notion of an immutable universe supported by Ptolemy and Aristotle, and led to major revolutions in astronomy and science.

17th-century Dutch Engineers
The 17th century lasted from January 1, 1601 (Roman numerals, MDCI), to December 31, 1700 (Roman numerals, MDCC). It falls into the early modern period of Europe and in that continent (whose impact on the world was increasing) was characterized by the Baroque cultural movement, the latter part of the Spanish Golden Age, the Dutch Golden Age, the French ''Grand Siècle'' dominated by Louis XIV, the Scientific Revolution, the world's first public company and megacorporation known as the Dutch East India Company, and according to some historians, the General Crisis. From the mid-17th century, European politics were increasingly dominated by the Kingdom of France of Louis XIV, where royal power was solidified domestically in the civil war of the Fronde. The semi-feudal territorial French nobility was weakened and subjugated to the power of an absolute monarchy through the reinvention of the Palace of Versailles from a hunting lodge to a gilded prison, in which a greatly expanded royal ...

Mayors Of Alkmaar
In many countries, a mayor is the highest-ranking official in a municipal government such as that of a city or a town. Worldwide, there is a wide variance in local laws and customs regarding the powers and responsibilities of a mayor as well as the means by which a mayor is elected or otherwise mandated. Depending on the system chosen, a mayor may be the chief executive officer of the municipal government, may simply chair a multi-member governing body with little or no independent power, or may play a solely ceremonial role. A mayor's duties and responsibilities may be to appoint and oversee municipal managers and employees, provide basic governmental services to constituents, and execute the laws and ordinances passed by a municipal governing body (or mandated by a state, territorial or national governing body). Options for selection of a mayor include direct election by the public, or selection by an elected governing council or board. The term ''mayor'' shares a linguistic o ...

Muiden
Muiden () is a city and former municipality in the Netherlands, in the province of North Holland. It lies at the mouth of the Vecht and is in an area called the Vechtstreek. Since 2016, Muiden has been part of the new municipality of Gooise Meren. History The first known reference to Muiden is from 953 when Otto I, Holy Roman Emperor, granted the settlement and its toll rights to Cathedral of Saint Martin, Utrecht. It was called ''Amuda'', meaning "mouth of the (river) A". "A" was the old name for the Vecht river. In 1122 Muiden was, together with Utrecht, granted some city rights by Emperor Henry V. After the lands around Muiden were given to Count Floris V, he began building Muider Castle at the mouth of the Vecht river. Muiden once again received city rights in 1296. The first defensive works date from the first half of the 15th century. In 1590 the walls are replaced with earthen mounds with bastions after a design by Adriaen Anthonisz. Muiden was the northern end o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naarden
Naarden () is a city and former municipality in the Gooi region in the province of North Holland, Netherlands. It has been part of the new municipality of Gooise Meren since 2016. History Naarden was granted its city rights in 1300 (the only town in the Gooi with these rights) and later developed into a fortified garrison town with a textile industry. Naarden is an example of a star fort, complete with fortified walls and a moat. The moat and walls have been restored on numerous occasions, most notably during the French era (1795-1814). After the Battle of Leipzig (1813), the Netherlands were liberated by an allied force of Dutch, Prussian and Russian armies. During this period, Naarden was besieged for months since the French commander didn't believe that Napoleon was captured. In May 1814, the French soldiers left the city in a retreat with honour (see Siege of Naarden (1813-1814). John Amos Comenius, 17th century Moravian born Czech educator was buried in the city, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
