Context: Hugo Christiaan Hamaker ( 23 March 1905 , Broek op Langedijk , North Holland -- 7 September 1993 , 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 ., After the explanation of van der Waals forces by Fritz London several scientists soon realised that his definition could be extended from the interaction of two molecules with induced dipoles to macro-scale objects by summing all of the forces between the molecules in each of the bodies involved. The theory is named after H. C. Hamaker who derived the interaction between two spheres, a sphere and a wall, and presented a general discussion in a heavily cited 1937 paper., A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge. However, in quantum physics, organic chemistry, and biochemistry, the term "molecule" is often used less strictly, also being applied to polyatomic ions., The Netherlands  is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three island territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing maritime borders with Belgium, the United Kingdom, and Germany. The largest cities in the Netherlands are Amsterdam, Rotterdam, The Hague and Utrecht. Amsterdam is the country's capital, while The Hague holds the Dutch seat of government and parliament. The name "Holland" is used to refer informally to the whole of the country of the Netherlands., The Dommel is a stream in Belgium and the Netherlands, left tributary of the Dieze. It rises in north-eastern Belgium near Peer and flows into the southern part of the Netherlands. The Dommel takes in water from the Keersop, Tongelreep, Run, Gender and Kleine Dommel streams and merges at 's-Hertogenbosch with the Aa stream to form river Dieze, which subsequently flows towards the Meuse. The main cities and towns along the Dommel's course are Peer, Neerpelt, Valkenswaard, Dommelen, Eindhoven, Son en Breugel, Sint-Oedenrode, Boxtel, Sint-Michielsgestel and 's-Hertogenbosch. The most original part and natural state of the Dommel can be found between Eindhoven and Boxtel. Here the Dommel has still its original winds and meanders and forms a cultural-historical and valuable landscape area called the Dommelbeemden., Fritz Wolfgang London (March 7, 1900  March 30, 1954) was a Jewish-German physicist and professor at Duke University. His fundamental contributions to the theories of chemical bonding and of intermolecular forces (London dispersion forces) are today considered classic and are discussed in standard textbooks of physical chemistry. With his brother Heinz London, he made a significant contribution to understanding electromagnetic properties of superconductors with the London equations and was nominated for the Nobel Prize in Chemistry on five separate occasions. , Friesland (official) or Frisia is a province in the northwest of the Netherlands. It is situated west of Groningen, northwest of Drenthe and Overijssel, north of Flevoland, northeast of North Holland, and south of the North Sea. In 2010, the province had a population of 646,000 and a total area of ., Broek op Langedijk (West Frisian: "Broek op Lengedìk") is a town in the Netherlands, located in the municipality of Langedijk in the province of North Holland., North Holland (, West Frisian: "Noard-Holland") is a province in the northwest of the Netherlands. It is situated on the North Sea, north of South Holland and Utrecht, and west of Friesland and Flevoland. As of 2015, it has a population of 2,762,163 and a total area of ., In physical chemistry, the van der Waals forces (or van der Waals interaction), named after Dutch scientist Johannes Diderik van der Waals, are the residual attractive or repulsive forces between molecules or atomic groups that do not arise from covalent bonds, nor ionic bonds. It can be shown that van der Waals forces are of the same origin as the Casimir effect, arising from quantum interactions with the zero-point field. The resulting van der Waals forces can be attractive or repulsive., Eindhoven is a municipality and a city in the south of the Netherlands, originally at the confluence of the Dommel and Gender streams. The Gender was dammed short of the city centre in the 1950s and the Dommel still runs through the city. The city has a population of 223,220 in January 2015, making it the fifth-largest municipality of the Netherlands and the largest in the province of North Brabant., Noord Brabant, also unofficially called Brabant, is a province in the south of the Netherlands. It borders the provinces of South Holland and Gelderland to the north, Limburg to the east, Zeeland to the west, and the Belgian provinces of Antwerp and Limburg to the south. The northern border follows the Meuse (Maas) river westward to its mouth in the Hollands Diep strait, part of the RhineMeuseScheldt delta.
History.
The Duchy of Brabant was a state of the Holy Roman Empire established in 1183 or 1190. It developed from the Landgraviate of Brabant and formed the heart of the historic Low Countries, part of the Burgundian Netherlands from 1430 and of the Habsburg Netherlands from 1482, until it was split up after the Dutch revolt. After the War of Independence, Catholics in the Southern Netherlands were systematically and officially discriminated against by the Northern Protestant government until the second half of the 20th century, which had a major influence on the economic and cultural development of the southern part of the Netherlands. 
Present-day North Brabant (Staats-Brabant) was adjudicated to the Generality Lands of the Dutch Republic according to the 1648 Peace of Westphalia, while the reduced duchy remained in existence with the Southern Netherlands until it was conquered by French Revolutionary forces in 1794., A municipality is usually a single urban administrative division having corporate status and powers of self-government or jurisdiction as granted by national and state laws, to which it is subordinate. It is to be distinguished from the county, which may encompass rural territory and/or numerous small communities such as towns, villages and hamlets. The term "municipality" may also mean the governing or ruling body of a given municipality. A municipality is a general-purpose administrative subdivision, as opposed to a special-purpose district. The term is derived from French "municipalité" and Latin "municipalis"., Subject: hugo christiaan hamaker, Relation: occupation, Options: (A) general (B) major (C) official (D) peer (E) physicist (F) physics (G) professor (H) scientist (I) united kingdom
