Habilitation
Habilitation is the highest university degree, or the procedure by which it is achieved, in many European countries. The candidate fulfills a university's set criteria of excellence in research, teaching and further education, usually including a dissertation. The degree, abbreviated "Dr. habil." (Doctor habilitatus) or "PD" (for "Privatdozent"), is a qualification for professorship in those countries. The conferral is usually accompanied by a lecture to a colloquium as well as a public inaugural lecture. History and etymology The term ''habilitation'' is derived from the Medieval Latin , meaning "to make suitable, to fit", from Classical Latin "fit, proper, skillful". The degree developed in Germany in the seventeenth century (). Initially, habilitation was synonymous with "doctoral qualification". The term became synonymous with "post-doctoral qualification" in Germany in the 19th century "when holding a doctorate seemed no longer sufficient to guarantee a proficient transfer o ...

X-ray Crystallography
X-ray crystallography is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal. From this electron density, the mean positions of the atoms in the crystal can be determined, as well as their chemical bonds, their crystallographic disorder, and various other information. Since many materials can form crystals—such as salts, metals, minerals, semiconductors, as well as various inorganic, organic, and biological molecules—X-ray crystallography has been fundamental in the development of many scientific fields. In its first decades of use, this method determined the size of atoms, the lengths and types of chemical bonds, and the atomic-scale differences among various mat ...

Gelehrtenschule Des Johanneums
The ''Gelehrtenschule des Johanneums'' ( ''Academic School of the Johanneum'', short: Johanneum) is a Gymnasium (or Grammar School ) in Hamburg, Germany. It is Hamburg's oldest school and was founded in 1529 by Johannes Bugenhagen. The school's focus is on the teaching of Latin and ancient Greek. It is proud of having educated some of Germany's political leaders as well as some of Germany's notable scientists. The school is operated and financed by the city of Hamburg. History The Johanneum was founded by Johannes Bugenhagen, the spiritual representative of the reformer Martin Luther. In 1528 he came to Hamburg to give the city an Evangelical Lutheran church order, "the Erbarn Stadt Hamborch Christlike Ordeninge". On 24 May, 1529, the Johanneum first opened its doors in the building of the secularized old St. Johannis monastery, on the site of today's Rathausmarkt as the "Latinsche Schole". The actual school rooms were in half-timbered buildings in the inner courtyard of the mon ...

Klaus Fuchs
Klaus Emil Julius Fuchs (29 December 1911 – 28 January 1988) was a German theoretical physicist and atomic spy who supplied information from the American, British and Canadian Manhattan Project to the Soviet Union during and shortly after World War II. While at the Los Alamos National Laboratory, Fuchs was responsible for many significant theoretical calculations relating to the first nuclear weapons and, later, early models of the hydrogen bomb. After his conviction in 1950, he served nine years in prison in the United Kingdom, then migrated to East Germany where he resumed his career as a physicist and scientific leader. The son of a Lutheran pastor, Fuchs attended the University of Leipzig, where his father was a professor of theology, and became involved in student politics, joining the student branch of the Social Democratic Party of Germany (SPD), and the ''Reichsbanner Schwarz-Rot-Gold'', the SPD's paramilitary organisation. He was expelled from the SPD in 1932, a ...

Elstead
Elstead is a civil parish in Surrey, England with shops, houses and cottages spanning the north and south sides of the River Wey; development is concentrated on two roads that meet at a central green. It includes Pot Common its southern neighbourhood. Hamlets in the parish, marginally separated from the village centre, are Charleshill and Elstead Common, both rich in woodland. Elstead lies between Farnham and Godalming on the B3001 road about west of the A3 Milford interchange. History Elstead's relative prosperity over the centuries can be partly attributed to the existence of the availability of a site for a watermill and a bridge over the river; parts of the bridge are dated to around 1300. The first known reference to Elstead is in the 1128 foundation charter for Waverley Abbey (sometimes spelt Waverly), where it was called ''Helestede''. The church of St James was built around ten years later. It still contains 13th-century windows and some 14th-century timbers and is a ...
