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. 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 Provinces of the Netherlands, province of North Holland, the Netherlands. History The village was first mentioned in the 12th century but documented in 1420 as "Broec" which means marshy or swampy land (broek in modern Dutch), and the modern name, Broek-op-Langedijk means "swampy land upon long dike". Broek op Langedijk developed along the dike as a linear settlement. The swamp was cultivated and upon the islands, farms were built, which were nicknamed "Rijk der duizend eilanden", meaning Realm/Empire of the thousand islands. 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 ...

People From Langedijk
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] |

1905 Births
As the second year of the massive Russo-Japanese War begins, more than 100,000 die in the largest world battles of that era, and the war chaos leads to the 1905 Russian Revolution against Nicholas II of Russia (Dmitri Shostakovich, Shostakovich's Symphony No. 11 (Shostakovich), 11th Symphony is subtitled ''The Year 1905'' to commemorate this) and the start of Revolution in the Kingdom of Poland (1905–07), Revolution in the Kingdom of Poland. Canada and the U.S. expand west, with the Alberta and Saskatchewan provinces and the founding of Las Vegas. 1905 is also the year in which Albert Einstein, at this time resident in Bern, publishes his four Annus Mirabilis papers, ''Annus Mirabilis'' papers in ''Annalen der Physik'' (Leipzig) (March 18, May 11, June 30 and September 27), laying the foundations for more than a century's study of theoretical physics.

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 Oxford University Press 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Applied Scientific Research
''Flow, Turbulence and Combustion'' is a peer-reviewed scientific journal on fluid mechanics. It covers original research on fluid mechanics and combustion, with the areas of interest including industrial, geophysical, and environmental applications. The journal was established in 1949 under the name ''Applied Scientific Research''. It obtained its present name in 1998, which also reflects its association with the European Research Community on Flow, Turbulence and Combustion (ERCOFTAC). Since the start in 1948, the journal was published by Martinus Nijhoff Publishers.

Tungsten
Tungsten (also called wolfram) is a chemical element; it has symbol W and atomic number 74. It is a metal found naturally on Earth almost exclusively in compounds with other elements. It was identified as a distinct element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternative name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements, melting at . It also has the highest boiling point, at . Its density is 19.254 g/cm3, 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 into metal. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many alloys ...
