H. C. Hamaker
Hugo Christiaan Hamaker (23 March 1905 in Broek op Langedijk, North Holland – 7 September 1993 in Eindhoven) was a Dutch scientist, who was responsible for the Hamaker theory which explains the van der Waals forces between objects larger than molecules. His 1937 paper was heavily cited. He completed his doctorate at the Universiteit Utrecht in 1934. His dissertation was labelled: ''Reflectivity and Emissivity of Tungsten; with a Description of a New Method to Determine the Total Reflectivity of Any Surface in a Simple and Accurate Way''. His adviser was Leonard Ornstein. From 1934 to 1967 he was employed in the Physical Laboratory of Philips in Eindhoven, and from 1960 to 1972 he was Professor at the Eindhoven University of Technology. In 1959 he was elected as a Fellow of the American Statistical Association. Publications Hamaker published the following papers: *H.C. Hamaker (1934).

Broek Op Langedijk
Broek op Langedijk (West Frisian Dutch: ''Broek op Lengedìk'') is a village in the municipality of Dijk en Waard in the province of North Holland, the Netherlands. History The village was first mentioned in the 12th century as 1420 Broec, and means "swampy land on the long dike". Broek op Langedijk developed along the dike as a linear settlement. The swamp was cultivated and the so-called empire of a thousand islands was formed. The islands were used to grow cabbage and in 1887, an auction house was established in Broek op Langedijk. The Dutch Reformed church is a single aisled church with wooden tower from the 15th century. Around 1860, the front and tower were renovated. The auction house is a large wooden complex surrounded by water. It was built in 1912 and was influenced by Jugendstil. In 1968, the auction merged with the Noord-Scharwoude auction and moved. In 1974, a museum was established in the former auction which allows visitors to bid on fruit and vegetables in hous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Langedijk
A person (plural, : 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 obligation, 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 us ...

Journal Of The Royal Statistical Society
The ''Journal of the Royal Statistical Society'' is a peer-reviewed scientific journal of statistics. It comprises three series and is published by Wiley for the Royal Statistical Society. History The Statistical Society of London was founded in 1834, but would not begin producing a journal for four years. From 1834 to 1837, members of the society would read the results of their studies to the other members, and some details were recorded in the proceedings. The first study reported to the society in 1834 was a simple survey of the occupations of people in Manchester, England. Conducted by going door-to-door and inquiring, the study revealed that the most common profession was mill-hands, followed closely by weavers. When founded, the membership of the Statistical Society of London overlapped almost completely with the statistical section of the British Association for the Advancement of Science. In 1837 a volume of ''Transactions of the Statistical Society of London'' were wri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tungsten
Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements barring carbon (which sublimes at normal pressure), melting at . It also has the highest boiling point, at . Its density is , comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many ...
