Marietta Blau
Marietta Blau (29 April 1894 – 27 January 1970) was an Austrian physicist credited with developing photographic nuclear emulsions that were usefully able to image and accurately measure high-energy nuclear particles and events, significantly advancing the field of particle physics in her time. For this, she was awarded the Lieben Prize by the Austrian Academy of Sciences. As a Jew, she was forced to flee Austria when Nazi Germany annexed it in 1938, eventually making her way to the United States. She was nominated for Nobel Prizes in both physics and chemistry for her work, but did not win. After her return to Austria, she won the Erwin Schrödinger Prize from the Austrian Academy of Sciences. Biography Blau was born on 29 April 1894 in a middle-class Jewish family, to Mayer (Markus) Blau, a court lawyer and music publisher, and his wife, Florentine Goldzweig. After having obtained the general certificate of education from the girls' high school run by the Association for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the Writing system#Directionality, directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Glossary of mathematical sym ...

University Of Frankfurt Am Main
Goethe University (german: link=no, Johann Wolfgang Goethe-Universität Frankfurt am Main) is a university located in Frankfurt am Main, Germany. It was founded in 1914 as a citizens' university, which means it was founded and funded by the wealthy and active liberal citizenry of Frankfurt. The original name was Universität Frankfurt am Main. In 1932, the university's name was extended in honour of one of the most famous native sons of Frankfurt, the poet, philosopher and writer/dramatist Johann Wolfgang von Goethe. The university currently has around 45,000 students, distributed across four major campuses within the city. The university celebrated its 100th anniversary in 2014. The first female president of the university, Birgitta Wolff, was sworn into office in 2015, and was succeeded by Enrico Schleiff in 2021. 20 Nobel Prize winners have been affiliated with the university, including Max von Laue and Max Born. The university is also affiliated with 18 winners of the Gottfri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Albert Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ' ...

Jews In Austria
The history of the Jews in Austria probably begins with the exodus of Jews from Judea under Roman occupation. Over the course of many centuries, the political status of the community rose and fell many times: during certain periods, the Jewish community prospered and enjoyed political equality, and during other periods it suffered pogroms, deportations to concentration camps and mass murder, and antisemitism. The Holocaust drastically reduced the Jewish community in Austria and only 8,140 Jews remained in Austria according to the 2001 census, though other estimates place the current figure at 9,000, 15,000, or 20,000 people, if accounting for those of mixed descent. Antiquity Jews have been in Austria since at least the 3rd century CE. In 2008 a team of archeologists discovered a third-century CE amulet in the form of a gold scroll with the words of the Jewish prayer Shema Yisrael (Hear, O Israel! The Lord is our God, the Lord is one) inscribed on it in the grave of a Jewish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cosmic-ray
Cosmic rays are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, and from distant galaxies. Upon impact with Earth's atmosphere, cosmic rays produce showers of secondary particles, some of which reach the surface, although the bulk is deflected off into space by the magnetosphere or the heliosphere. Cosmic rays were discovered by Victor Hess in 1912 in balloon experiments, for which he was awarded the 1936 Nobel Prize in Physics. Direct measurement of cosmic rays, especially at lower energies, has been possible since the launch of the first satellites in the late 1950s. Particle detectors similar to those used in nuclear and high-energy physics are used on satellites and space probes for research into cosmic rays. Data from the Fermi Space Telescope (2013) have been interpreted as evidence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spallation
Spallation is a process in which fragments of material (spall) are ejected from a body due to impact or stress. In the context of impact mechanics it describes ejection of material from a target during impact by a projectile. In planetary physics, spallation describes meteoritic impacts on a planetary surface and the effects of stellar winds and cosmic rays on planetary atmospheres and surfaces. In the context of mining or geology, spallation can refer to pieces of rock breaking off a rock face due to the internal stresses in the rock; it commonly occurs on mine shaft walls. In the context of anthropology, spallation is a process used to make stone tools such as arrowheads by knapping. In nuclear physics, spallation is the process in which a heavy nucleus emits numerous nucleons as a result of being hit by a high-energy particle, thus greatly reducing its atomic weight. In industrial processes and bioprocessing the loss of tubing material due to the repeated flexing of the tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hertha Wambacher
Hertha Wambacher (9 March 1903 in Vienna – 25 April 1950 in Vienna) was an Austrian physicist. Education After having obtained the general certificate of education from the girls' high school run by the Association for the Extended Education of Women in 1922, she studied first chemistry, then physics at the University of Vienna. Work with Marietta Blau Wambacher's dissertation at the 2nd Physics Institute was supervised by Marietta Blau, with whom Wambacher continued to collaborate also after her Ph.D. graduation in 1932. The cooperation of the two women referred to the photographic method of detecting ionizing particles. For their methodical studies at the Institute for Radium Research of the Austrian Academy of Sciences in Vienna, Blau and Wambacher received the Lieben Prize of the Austrian Academy of Sciences in 1937. Also in 1937, Blau and Wambacher jointly discovered "disintegration stars" in photographic plates that had been exposed to cosmic radiation at an altitude o ...
