Johannes Bosscha
Johannes Bosscha Jr. (18 November 1831 – 15 April 1911) was a Dutch physicist. Bosscha came from a family long known for their academic achievements. His great-grandfather and grandfather were classical scholars. His father, Johannes Bosscha Sr. (1797–1874), was a professor of history and literature and also was minister of church-state relationships in two governments (1853–1861). From 1844–1848 Johannes Jr. attended a Latin school in Amsterdam, after which he enrolled at Leiden University. In 1854 he obtained his doctoral degree (promotor Pieter Rijke) with a thesis on galvanometry. After a brief sojourn in Berlin he returned to the physics department in Leiden. Here he made important investigations on galvanic polarization and the rapidity of sound waves. He initiated the mechanical theory of electrolysis, and he was one of the first (1855) to suggest the possibility of sending two messages simultaneously over the same wire. In 1858 he published "Conservation of En ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heike Kamerlingh Onnes
Heike Kamerlingh Onnes (21 September 1853 – 21 February 1926) was a Dutch physicist and Nobel laureate. He exploited the Hampson–Linde cycle to investigate how materials behave when cooled to nearly absolute zero and later to liquefy helium for the first time, in 1908. He also discovered superconductivity in 1911. Biography Early years Kamerlingh Onnes was born in Groningen, Netherlands. His father, Harm Kamerlingh Onnes, was a brickworks owner. His mother was Anna Gerdina Coers of Arnhem. In 1870, Kamerlingh Onnes attended the University of Groningen. He studied under Robert Bunsen and Gustav Kirchhoff at the University of Heidelberg from 1871 to 1873. Again at Groningen, he obtained his master's degree in 1878 and a doctorate in 1879. His thesis was ''Nieuwe bewijzen voor de aswenteling der aarde'' (''tr''. New proofs of the rotation of the earth). From 1878 to 1882 he was assistant to Johannes Bosscha, the director of the Delft Polytechnic, for whom he substituted as le ...

People From Breda
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

19th-century Dutch Physicists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century 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, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, 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 Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bosscha Observatory
Bosscha Observatory is the oldest modern observatory in Indonesia, and one of the oldest in Asia. The observatory is located in Lembang, West Java, approximately north of Bandung. It is situated on a hilly six hectares of land and is above mean sea level plateau. The IAU observatory code for Bosscha is 299. History During the first meeting of the ''Nederlandsch-Indische Sterrekundige Vereeniging'' (Dutch-Indies Astronomical Society) in the 1920s, it was agreed that an observatory was needed to study astronomy in the Dutch East Indies. Of all locations in the Indonesia archipelago, a tea plantation in Malabar, a few kilometers north of Bandung in West Java was selected. It is on the hilly north side of the city with a non-obstructed view of the sky and with close access to the city that was planned to become the new capital of the Dutch colony, replacing Batavia (present-day Jakarta). The observatory is named after the tea plantation owner Karel Albert Rudolf Bosscha, son of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
