Pieter Rijke
Petrus Leonardus Rijke (11 July 1812 – 7 April 1899) was a Dutch physicist, and a professor in experimental physics at the University of Leiden. Rijke spent his scientific career exploring the physics of electricity, and is known for the Rijke tube. On 1 July 1852 he married Johanna Hamaker. They had 6 sons and 6 daughters. Early years and education Rijke was born in Hemmen, (now Overbetuwe municipality), Gelderland. His father, Dirk Rijke, was a pastor. His mother was Elisabeth Pieternella Beausar. From 1830 Rijke studied physics under at the University of Leiden, where he obtained his Ph.D. in 1836. The title of his Ph.D. thesis was "De origine electricitatis voltaicae".

Overbetuwe
Overbetuwe () is a municipality in the province of Gelderland in the Netherlands. It was formed on 1 January 2001 as a merger of three former municipalities: Elst, Heteren and Valburg. Overbetuwe is bordered in the north by the river Rhine and in the south by the river Waal. The town hall is located in Elst, the largest town in the municipality. Since 2021 it has been part of the Arnhem-Nijmegen Green Metropolitan Region (, which aids planning and development in the region's eighteen municipalities.

Academic Staff Of Leiden University
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of tertiary education. The name traces back to Plato's school of philosophy, founded approximately 386 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and Skills, skill, north of Ancient Athens, Athens, Greece. The Royal Spanish Academy defines academy as scientific, literary or artistic society established with public authority and as a teaching establishment, public or private, of a professional, artistic, technical or simply practical nature. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the Gymnasium (ancient Greece), gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive Grove (nature), grove, hence the expression "the groves of Academe". In these gardens, the philos ...

19th-century Dutch Physicists
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm cer ...

People From Overbetuwe
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heike Kamerlingh Onnes
Heike Kamerlingh Onnes (; 21 September 1853 – 21 February 1926) was a Dutch Experimental physics, experimental physicist. After studying in Groningen and Heidelberg, he became Professor of Experimental Physics at Leiden University, where he taught from 1882 to 1923. In 1904, he established a cryogenics laboratory where he exploited the Hampson–Linde cycle to investigate how materials behave when cooled to nearly absolute zero. In 1908, he became the first to liquefaction of gases, liquefy helium, cooling it to near 1.5 kelvin, at the time the coldest temperature achieved on earth. For this research, he was awarded the Nobel Prize in Physics in 1913. Using liquid helium to investigate the electrical conductivity of solid mercury (element), mercury, he found in 1911 that at 4.2 K its electrical resistance vanishes, thus discovering superconductivity. Early life Kamerlingh Onnes was born in Groningen, Netherlands. His father, Harm Kamerlingh Onnes, was a brickworks owner. His ...

Johannes Diderik Van Der Waals
Johannes Diderik van der Waals (; 23 November 1837 – 8 March 1923) was a Dutch theoretical physicist who received the Nobel Prize in Physics in 1910 "for his work on the equation of state for gases and liquids". Van der Waals started his career as a schoolteacher. He became the first physics professor of the University of Amsterdam when its status was upgraded to Municipal University in 1877. His name is primarily associated with the van der Waals equation, an equation of state that describes the behavior of gases and their condensation to the liquid phase. His name is also associated with van der Waals forces (forces between stable molecules), with van der Waals molecules (small molecular clusters bound by van der Waals forces), and with the van der Waals radius (size of molecules). James Clerk Maxwell once said that, "there can be no doubt that the name of Van der Waals will soon be among the foremost in molecular science." In his 1873 thesis, Van der Waals noted the ...

Professor
Professor (commonly abbreviated as Prof.) is an Academy, academic rank at university, universities and other tertiary education, post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a 'person who professes'. Professors are usually experts in their field and teachers of the highest rank. In most systems of List of academic ranks, academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word ''professor'' is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well, and often to instructors or lecturers. Professors often conduct original research and commonly teach undergraduate, Postgraduate educa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
