Ehrenhaft
Felix Ehrenhaft (24 April 1879 – 4 March 1952) was an Austrian physicist who contributed to atomic physics, to the measurement of electrical charges and to the optical properties of metal colloids. He was known for his maverick and controversial style. His fearless iconoclasm was greatly admired by philosopher Paul Feyerabend. He won the Haitinger Prize of the Austrian Academy of Sciences in 1917. Biography Early years Ehrenhaft was born in Vienna to physician Leopold Ehrenhaft and Louise Eggar, the daughter of a Hungarian industrialist. Ehrenhaft earned his doctorate from the University of Vienna in 1903, working on the optical properties of metallic colloids. He subsequently became assistant to Franz S. Exner. Middle years In 1907, the reality of atoms was still disputed but Albert Einstein and Marian Smoluchowski had both recently given accounts of Brownian motion in liquids, strongly supporting the atomic theory. Though Theodor Svedberg had made important demonstrati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olga Ehrenhaft-Steindler
Olga Ehrenhaft-Steindler (28 October 1879 – 21 December 1933) was an Austrians, Austrian physicist and science teacher. In 1903, she became the first woman to earn a physics doctorate at the University of Vienna. She established the first ''Vienna Business School, Wiener Handelsakademie für Mädchen'' (Vienna Commercial Academy for Girls), as well as a grammar school for girls, in 1907. Biography Early years Olga Steindler was born in Vienna to lawyer Leopold Steindler and Caroline Steindler, née Goldberg. She had three siblings. As women could not take the ''Matura'' (comparable to A-Level exams) in Vienna at the time, Olga Steindler went to Prague, where she took her exam on 7 July 1899. Steindler began to study mathematics and physics at Vienna University in 1899, which was then newly possible for women. She wrote her thesis on the validity of the Helmholtz equation for various elements. Her doctoral adviser was Franz Serafin Exner. In 1903, she became the first woman to ...

Lieben Prize
The Ignaz Lieben Prize, named after the Austrian banker , is an annual Austrian award made by the Austrian Academy of Sciences to young scientists working in the fields of molecular biology, chemistry, or physics. Biography The Ignaz Lieben Prize has been called the Austrian Nobel Prize. It is similar in intent but somewhat older than the Nobel Prize. The Austrian merchant Ignaz L. Lieben, whose family supported many philanthropic activities, had stipulated in his testament that 6,000 florins should be used “for the common good”. In 1863 this money was given to the Austrian Imperial Academy of Sciences, and the Ignaz L. Lieben Prize was instituted. Every three years, the sum of 900 florins was to be given to an Austrian scientist in the field of chemistry, physics, or physiology. This sum corresponded to roughly 40 per cent of the annual income of a university professor. From 1900 on, the prize was offered on a yearly basis. The endowment was twice increased by the Lieben fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marian Smoluchowski
Marian Smoluchowski (; 28 May 1872 – 5 September 1917) was a Polish physicist who worked in the Polish territories of the Austro-Hungarian Empire. He was a pioneer of statistical physics, and an avid mountaineer. Life Born into an upper-class family in Vorder-Brühl, near Vienna, Smoluchowski studied physics at the University of Vienna. His teachers included Franz S. Exner and Joseph Stefan. Ludwig Boltzmann held a position at Munich University during Smoluchowski's studies in Vienna, and Boltzmann returned to Vienna in 1894 when Smoluchowski was serving in the Austrian army. They apparently had no direct contact, although Smoluchowski's work follows in the tradition of Boltzmann's ideas. After several years at other universities (Paris, Glasgow, Berlin), in 1899 Smoluchowski moved to Lwów (present-day Lviv), where he took a position at the University of Lwów. He was president of the Polish Copernicus Society of Naturalists, 1906–7. In 1913 Smoluchowski moved to K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atom
Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons. Only the most common variety of hydrogen has no neutrons. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across. They are so small that accurately predicting their behavior using classical physics, as if they were tennis balls for example, is not possible due to quantum effects. More than 99.94% of an atom's mass is in the nucleus. The protons have a positive electric charge, the electrons have a negative electric charge, and the neutrons have no electric charge. If the number of protons and electrons are equal, then the atom is electrically neutral. If an atom has more or fewer electrons than protons, then it has an overall negative or positive charge, respectively – such atoms are called ions. The electrons of an atom are a ...

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 ' ...
