Teapot Dribble
The teapot effect, also known as dribbling, is a fluid dynamics phenomenon that occurs when a liquid being pouring, poured from a container runs down the spout or the body of the vessel instead of flowing out in an arc. Markus Reiner coined the term "teapot effect" in 1956 to describe the tendency of liquid to dribble down the side of a vessel while pouring. Reiner received his PhD at TU Wien in 1913 and made significant contributions to the development of the study of flow behavior known as rheology. Reiner believed the teapot effect could be explained by Bernoulli's principle, which states that an increase in the speed of a fluid is always accompanied by a decrease in its pressure. When tea is poured from a teapot, the liquid's speed increases as it flows through the narrowing spout. This decrease in pressure was what Reiner thought to cause the liquid to dribble down the side of the pot. However, a 2021 study found the primary cause of the phenomenon to be an interaction of ...

American Institute Of Physics
The American Institute of Physics (AIP) promotes science and the profession of physics, publishes physics journals, and produces publications for scientific and engineering societies. The AIP is made up of various member societies. Its corporate headquarters are at the American Center for Physics in College Park, Maryland, but the institute also has offices in Melville, New York, and Beijing. Historical overview The AIP was founded in 1931 as a response to lack of funding for the sciences during the Great Depression. /www.aip.org/aip/history "History of AIP" American Institute of Physics. July 2010. The AIP was founded in 1931 at a joint meeting between four physics societies: the American Physical Society, the Optical Society of America, the Acoustical Society of America, and the Society of Rheology. These were soon joined by the American Association of Physics Teachers, for a total of five societies. It formally incorporated in 1932 consisting of five original "member so ...

Deutsches Porzellanmuseum
The Porzellanikon is a museum complex dealing with the production of porcelain and ceramics in Selb and Hohenberg an der Eger in the district of Wunsiedel (district), Wunsiedel i. Fichtel Mountains, Fichtelgebirge (Upper Franconia, Oberfranken) in Germany. The complex of museums was the result of the merger of the European Industrial Museum for Porcelain, the European Museum of Technical Ceramics, the Rosenthal Museum and the German Porcelain Museum in Hohenberg an der Eger. Since 2012, the Porzellanikon has been included in the as a member of the "UNIC" ("Urban Network for Innovation in Ceramics"). The museum was developed under founding director Wilhelm Siemen beginning in 1984 and expanded over several decades. It includes the restored former Rosenthal (company), Rosenthal factory in Selb, which Siemen helped incorporate into the museum. In 2014, Porzellanikon was designated a state museum of Bavaria.

Fluid Dynamics
In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases. It has several subdisciplines, including (the study of air and other gases in motion) and (the study of water and other liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space, understanding large scale geophysical flows involving oceans/atmosphere and modelling fission weapon detonation. Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem typically involves the calculation of various properties of the fluid, such as flow ...

Physics Of Fluids
''Physics of Fluids'' is a monthly peer-reviewed scientific journal covering fluid dynamics, established by the American Institute of Physics in 1958, and is published by AIP Publishing. The journal focus is the dynamics (physics), dynamics of gases, liquids, and complex or multiphase flow, multiphase fluids—and the journal contains original research resulting from theoretical physics, theoretical, computational fluid dynamics, computational, and experimental physics, experimental studies. History From 1958 through 1988, the journal included plasma (physics), plasma physics. From 1989 until 1993, the journal split into ''Physics of Fluids A'' covering fluid dynamics, and ''Physics of Fluids B,'' on plasma physics. In 1994, the latter was renamed ''Physics of Plasmas'', and the former continued under its original name, ''Physics of Fluids''. The journal was originally published by the American Institute of Physics in cooperation with the American Physical Society's Division of Fl ...

Melitta
Melitta () is a German company selling coffee, paper coffee filters, and coffee makers, part of the Melitta Group, which has branches in other countries. The company is headquartered in Minden, North Rhine-Westphalia. It is named after Melitta Bentz (1873–1950) who founded the company after she invented the drip brew paper coffee filter (German patent granted 8 July 1908). Bentz later ran the company as a family business. History In 1908, Melitta Bentz, a 35-year-old woman from Dresden, Germany, invented the first coffee filter, receiving a patent registration for her "Filter Top Device lined with Filter Paper" from the Patent Office in Berlin on 8 July. She founded the company bearing her name the same year. In the 1930s, Melitta revised the original filter, tapering it into the shape of a cone and adding ribs. This created a larger filtration area, allowing for improved extraction of the ground coffee. In 1936, the widely recognized cone-shaped filter paper that ...

Alcock, Lindley & Bloore Ltd
Samuel Alcock (1799–1848) was an English pottery manufacturer who operated as Samuel Alcock & Co in Burslem, Staffordshire from 1828 to 1859. They were especially noted for "picture jugs" modelled and moulded in relief in various ceramic materials, a popular type of object in these years. Samuel Alcock & Co. Alcock was born in Kingsley, Staffordshire. He was the youngest of the nine children of Thomas (1746–1816) and Catherine Alcock (1756–1838). Though from a farming background, he developed an interest in commerce after working with his uncle Joseph Locker, a grocer, tea dealer, provision dealer, chandler and banker of the Market Square, Hanley, Staffordshire, Hanley. His introduction to pottery came when he embarked upon a partnership with Ralph Stevenson of Cobridge, Staffordshire. In 1828, Alcock developed his own business and began work on the Hill Top site in Cobridge. By the 1830s Stevenson employed 600 people at his works. In 1839 he completed work on a large fac ...
