His father was Gustav Hertz who, along with James Franck, was awarded the Nobel Prize in Physics 1925 for their experiments on inelastic electron collisions in gases. Gustav Hertz's uncle was in turn Heinrich Hertz, who first conclusively proved the existence of the electromagnetic waves. Hellmuth graduated from the elite Schule Schloss Salem boarding school in 1939 at the age of 19 years with the highest grade in mathematics and physics. The same year, he was conscripted into the German Army (Wehrmacht) and served as a soldier for Nazi Germany in World War II. In 1943 he was captured in the North African theatre by US t ...

Berlin is Capital of Germany, the capital and largest city of Germany, both by area and List of cities in Germany by population, by population. Its more than 3.85 million inhabitants make it the European Union's List of cities in the European Union by population within city limits, most populous city, as measured by population within city limits having gained this status after the United Kingdom's, and thus London's, Brexit, departure from the European Union. Simultaneously, the city is one of the states of Germany, and is the List of German states by area, third smallest state in the country in terms of area. Berlin is surrounded by the state of Brandenburg, and Brandenburg's capital Potsdam is nearby. The urban area of Berlin has a population of over 4.5 million and is therefore the most populous urban area in Germany. The Berlin/Brandenburg Metropolitan Region, Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's second-largest metropolitan reg ...

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 p ...

Birgit Ann-Marie Margareta Nordbring-Hertz, (16 May 1923 – 16 March 2020 in Lund, Sweden) was a Swedish scientist at Lund University known for her work on the interactions between fungi and nematodes. Education Nordbring-Hertz graduated with a medical licentiate degree with a thesis on the opportunistic human pathogenic fungus, ''Candida albicans'', 1956 at Lund University, and received a doctorate in microbiology in 1974 at the same university, working on nematode-trapping fungi. After her doctorate she took over responsibility for the department of microbial ecology, a position she held from 1975 until 1989. In 1987, she was promoted to professor at Lund University, and in 1989 she transitioned to an emeritus position. She was the first female professor at the natural science faculty at Lund University. Research Nordbring-Hertz's research mainly dealt with a type of microfungi, so-called nematophagous fungi, that infect and digest nematodes. She concentrated on the nemato ...

Niels Bohr
Niels Henrik David Bohr (; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research. Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. Although the Bohr model has been supplanted by other models, its underlying principles remain valid. He conceived the principle of complementarity: that items could be separately analysed in terms of contradictory properties, like behaving as a wave or a stream of particles. The notion of complementarity dominated Bohr's thinking in both science and philosophy. Bohr founded the Institute of Theoretical Physics at the University of ...
