Steven Hoogendijk
Steven Hoogendijk (1 April 1698 – 3 July 1788) was a Rotterdam watch and instrument maker and physicist. His portrait to the right, shows him pointing to an early pyrometer from Pieter van Musschenbroeck with pumps in the background. In 1769, Steven Hoogendijk co-founded the Batavian Society for Experimental Philosophy, with a main aim of introducing the steam engine in the Netherlands, and with the motto: "Certos Feret experientia fructus" (experience will give reliable products). With the support of the Society at their own expense they brought a Thomas Newcomen, Newcomen steam engine from England to an old Powder Tower at the edge of Rotterdam. On 9 March 1776, the machine was first put into operation. The steam engine components worked well, but the self-designed wooden Hoogendijk pumps were not compatible and quickly collapsed. This made it such an impression that in 1787 a new steam engine was built in the Polder, Polder Blijdorp. The expected theoretical capacity of 1750 ...

Rotterdam
Rotterdam ( , , , lit. ''The Dam on the River Rotte'') is the second largest city and municipality in the Netherlands. It is in the province of South Holland, part of the North Sea mouth of the Rhine–Meuse–Scheldt delta, via the ''"New Meuse"'' inland shipping channel, dug to connect to the Meuse first, but now to the Rhine instead. Rotterdam's history goes back to 1270, when a dam was constructed in the Rotte. In 1340, Rotterdam was granted city rights by William IV, Count of Holland. The Rotterdam–The Hague metropolitan area, with a population of approximately 2.7 million, is the 10th-largest in the European Union and the most populous in the country. A major logistic and economic centre, Rotterdam is Europe's largest seaport. In 2020, it had a population of 651,446 and is home to over 180 nationalities. Rotterdam is known for its university, riverside setting, lively cultural life, maritime heritage and modern architecture. The near-complete destruction ...

Pyrometer
A pyrometer is a type of remote-sensing thermometer used to measure the temperature of distant objects. Various forms of pyrometers have historically existed. In the modern usage, it is a device that from a distance determines the temperature of a surface from the amount of the thermal radiation it emits, a process known as pyrometry and sometimes radiometry. The word pyrometer comes from the Greek word for fire, "πῦρ" (''pyr''), and ''meter'', meaning to measure. The word pyrometer was originally coined to denote a device capable of measuring the temperature of an object by its incandescence, visible light emitted by a body which is at least red-hot. Modern pyrometers or infrared thermometers also measure the temperature of cooler objects, down to room temperature, by detecting their infrared radiation flux. Principle It is based on the principle that the intensity of light received by the observer depends upon distance of observer from source and temperature of dis ...

Pieter Van Musschenbroeck
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. The Van Musschenbroeks, originally from Flanders, had lived in the city of Leid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batavian Society For Experimental Philosophy
The Batavian Society for Experimental Philosophy ( nl, Bataafsch Genootschap voor Proefondervindelijke Wijsbegeerte) is a Dutch learned society residing in Rotterdam. History The society was founded on June 3, 1769 after Steven Hoogendijk declared in his last will that after his death a foundation for the furtherance of experimental philosophy (a term now called 'Science') would inherit his fortune. His fortune would be more than sufficient to secure the foundation's financial future for a long time. The society met as a gentlemen's club of amateur scientists. The initial directors were:Steven Hogendijk in A.J. van der Aa * dr. |
Thomas Newcomen
Thomas Newcomen (; February 1664 – 5 August 1729) was an English inventor who created the atmospheric engine, the first practical fuel-burning engine in 1712. He was an ironmonger by trade and a Baptist lay preacher by calling. He was born in Dartmouth, in Devon, England, to a merchant family and baptised at St. Saviour's Church on 28 February 1664. In those days flooding in coal and tin mines was a major problem. Newcomen was soon engaged in trying to improve ways to pump out the water from such mines. His ironmonger's business specialised in designing, manufacturing and selling tools for the mining industry. Religious life Thomas Newcomen was a lay preacher and a teaching elder in the local Baptist church. After 1710 he became the pastor of a local group of Baptists. His father had been one of a group who brought the well-known Puritan John Flavel to Dartmouth. Later one of Newcomen's business contacts in London, Edward Wallin, was another Baptist minister who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polder
A polder () is a low-lying tract of land that forms an artificial hydrological entity, enclosed by embankments known as dikes. The three types of polder are: # Land reclaimed from a body of water, such as a lake or the seabed # Flood plains separated from the sea or river by a dike # Marshes separated from the surrounding water by a dike and subsequently drained; these are also known as ''koogs'', especially in Germany The ground level in drained marshes subsides over time. All polders will eventually be below the surrounding water level some or all of the time. Water enters the low-lying polder through infiltration and water pressure of groundwater, or rainfall, or transport of water by rivers and canals. This usually means that the polder has an excess of water, which is pumped out or drained by opening sluices at low tide. Care must be taken not to set the internal water level too low. Polder land made up of peat (former marshland) will sink in relation to its previous l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
