Johanna Geertruida Van Cittert-Eymers
Johanna Geertruida (Truus) van Cittert-Eymers was a Dutch physicist, historian of science, museum director and author. Early years Johanna Geertruida Eymers was born in Velp, in the Netherlands on 19 June 1903, the only child of teacher Johan Anton Eymers and Johanna Hermina Aleida Huetinck. She graduated from secondary school with a HBS-b diploma in Arnhem in 1921 and moved to Utrecht to begin studying physics at the university there in 1923. Career Eymers began work as a researcher in the experimental physics group of Leonard Ornstein at Utrecht University in 1929 and in 1932 became the head of the teaching laboratory. Ornstein's group did both pure and applied research, with the latter often at the request of businesses or government institutions. Thus it came to be that Eymers published research about atomic emission spectra but her doctoral research concerned the illumination of an art gallery in The Hague. Eymers graduated cum laude with a PhD in 1935 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Women Physicists
A woman is an adult female human. Prior to adulthood, a female human is referred to as a girl (a female child or adolescent). The plural ''women'' is sometimes used in certain phrases such as " women's rights" to denote female humans regardless of age. Typically, women inherit a pair of X chromosomes, one from each parent, and are capable of pregnancy and giving birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, SRY-gene on either one of the respective sex chromosomes. Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. A fully developed woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. Women have significantly less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular th ...

Historians Of Physics
A historian is a person who studies and writes about the past and is regarded as an authority on it. Historians are concerned with the continuous, methodical narrative and research of past events as relating to the human race; as well as the study of all history in time. Some historians are recognized by publications or training and experience.Herman, A. M. (1998). Occupational outlook handbook: 1998–99 edition. Indianapolis: JIST Works. Page 525. "Historian" became a professional occupation in the late nineteenth century as research universities were emerging in Germany and elsewhere. Objectivity During the ''Irving v Penguin Books and Lipstadt'' trial, people became aware that the court needed to identify what was an "objective historian" in the same vein as the reasonable person, and reminiscent of the standard traditionally used in English law of "the man on the Clapham omnibus". This was necessary so that there would be a legal benchmark to compare and contrast the scholar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marriage Bar
A marriage bar is the practice of restricting the employment of married women. Common in Western countries from the late 19th century to the 1970s, the practice often called for the termination of the employment of a woman on her marriage, especially in teaching and clerical occupations. Further, widowed women with children were still considered to be married at times, preventing them from being hired, as well. The practice lacked an economic justification, and its rigid application was often disruptive to workplaces. However, marriage bars were widely relaxed in wartime due to an increase in the demand for labor. Research carried out by Claudia Goldin to explore their determinants using firm-level data from 1931 and 1940, find out that they are associated with promotion from within, tenure-based salaries, and other modern personnel practices. Since the 1960s, the practice has widely been regarded as employment inequality and sexual discrimination, and has been either discontinu ...

Bioluminescent Bacteria
Bioluminescent bacteria are Bioluminescence, light-producing bacteria that are predominantly present in sea water, marine sediments, the surface of decomposing fish and in the gut of marine animals. While not as common, bacterial bioluminescence is also found in terrestrial and freshwater bacteria. These bacteria may be free living (such as ''Vibrio harveyi'') or in symbiosis with animals such as the Hawaiian Bobtail Squid, Hawaiian Bobtail squid (''Aliivibrio fischeri'') or terrestrial nematodes (''Photorhabdus luminescens''). The host organisms provide these bacteria a safe home and sufficient nutrition. In exchange, the hosts use the light produced by the bacteria for camouflage, prey and/or mate attraction. Bioluminescent bacteria have evolved symbiotic relationships with other organisms in which both participants benefit close to equally. Another possible reason bacteria use luminescence reaction is for quorum sensing, an ability to regulate gene expression in response to bacter ...

Biophysics
Biophysics is an interdisciplinary science that applies approaches and methods traditionally used in physics to study biological phenomena. Biophysics covers all scales of biological organization, from molecular to organismic and populations. Biophysical research shares significant overlap with biochemistry, molecular biology, physical chemistry, physiology, nanotechnology, bioengineering, computational biology, biomechanics, developmental biology and systems biology. The term ''biophysics'' was originally introduced by Karl Pearson in 1892.Roland Glaser. Biophysics: An Introduction'. Springer; 23 April 2012. . The term ''biophysics'' is also regularly used in academia to indicate the study of the physical quantities (e.g. electric current, temperature, stress, entropy) in biological systems. Other biological sciences also perform research on the biophysical properties of living organisms including molecular biology, cell biology, chemical biology, and biochemistry. Overview ...

Latin Honors
Latin honors are a system of Latin phrases used in some colleges and universities to indicate the level of distinction with which an academic degree has been earned. The system is primarily used in the United States. It is also used in some Southeastern Asian countries with European colonial history, such as Indonesia and the Philippines, although sometimes translations of these phrases are used instead of the Latin originals. The honors distinction should not be confused with the honors degrees offered in some countries, or with honorary degrees. The system usually has three levels of honor: ''cum laude'', ''magna cum laude'', and ''summa cum laude''. Generally, a college or university's regulations set out definite criteria a student must meet to obtain a given honor. For example, the student might be required to achieve a specific grade point average, submit an honors thesis for evaluation, be part of an honors program, or graduate early. Each school sets its own standards. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kunstmuseum Den Haag
The Kunstmuseum Den Haag is an art museum in The Hague in the Netherlands, founded in 1866 as the Museum voor Moderne Kunst. Later, until 1998, it was known as Haags Gemeentemuseum, and until the end of September 2019 as Gemeentemuseum Den Haag. It has a collection of around 165,000 works, over many different forms of art. In particular, the Kunstmuseum is renowned for its large Mondrian collection, the largest in the world. Mondrian's last work, ''Victory Boogie-Woogie'', is on display at the museum. The current museum building was constructed between 1931–1935, designed by the Dutch architect H.P. Berlage. The KM21 (museum for contemporary art) and Fotomuseum Den Haag (The Hague museum for photography) are part of the Kunstmuseum, though not housed in the same building and with a separate entrance fee. Collection Modern art The museum's collection of modern art includes works by international artists (Edgar Degas, Claude Monet, Pablo Picasso, Egon Schiele, Frank Stella, ...
