He was among the first to write books on science for a broad Jewish audience, and was the founder of '' Ha-Tsfira'', the first Hebrew-language newspaper with an emphasis on the sciences. Biography Ḥayyim Selig Slonimski was born in Bialystok, in the Grodno Governorate of the Russian Empire (present-day Poland), the oldest son of Rabbi Avraham Ya'akov Bishka and Leah (Neches) Bishka.

Crelle's Journal
''Crelle's Journal'', or just ''Crelle'', is the common name for a mathematics journal, the ''Journal für die reine und angewandte Mathematik'' (in English: ''Journal for Pure and Applied Mathematics''). History The journal was founded by August Leopold Crelle (Berlin) in 1826 and edited by him until his death in 1855. It was one of the first major mathematical journals that was not a proceedings of an academy. It has published many notable papers, including works of Niels Henrik Abel, Georg Cantor, Gotthold Eisenstein, Carl Friedrich Gauss and Otto Hesse. It was edited by Carl Wilhelm Borchardt from 1856 to 1880, during which time it was known as ''Borchardt's Journal''. The current editor-in-chief is Daniel Huybrechts ( Rheinische Friedrich-Wilhelms-Universität Bonn).

Pale Of Settlement
The Pale of Settlement was a western region of the Russian Empire with varying borders that existed from 1791 to 1917 (''de facto'' until 1915) in which permanent settlement by Jews was allowed and beyond which the creation of new Jewish settlements, permanent or temporary, was mostly forbidden. Jews were allowed to live outside the area, including those with university education, the ennobled, members of the most affluent of the merchant guilds and particular artisans, some military personnel and some services associated with them, including their families, and sometimes their servants. Pale is an archaic term meaning an enclosed area. Jews were also allowed to settle in colonies outside of the Pale, such as in Siberia. The Pale of Settlement included all of modern-day Belarus and Moldova, much of Lithuania, Ukraine and east-central Poland, and relatively small parts of Latvia and what is now the western Russian Federation. It extended from the eastern ''pale'', or demarcation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Wilhelm Leibniz, Gottfried Leibniz. From its establishment, the academy benefitted from a slate of foreign scholars as professors; the academy then gained its first clear set of goals from the 1747 Charter. The academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few Academy name changes, ending as The Imperial ...

Ruble
The ruble or rouble (; rus, рубль, p=rublʲ) is a currency unit. Currently, currencies named ''ruble'' in circulation include the Russian ruble (RUB, ₽) in Russia and the Belarusian ruble (BYN, Rbl) in Belarus. These currencies are subdivided into one hundred kopeks. No kopek is currently formally subdivided, although '' denga'' (½ kopek) and ''polushka'' (½ denga, thus ¼ kopek) were minted until the 19th century. Additionally, the Transnistrian ruble is used in Transnistria, an unrecognized breakaway province of Moldova. Historically, the grivna, ruble and denga were used in Russia as measurements of weight. In 1704, as a result of monetary reforms by Peter the Great, the imperial ruble of the Russian Empire became the first decimal currency. The silver ruble was used until 1897 and the gold ruble was used until 1917. The Soviet ruble officially replaced the imperial ruble in 1922 and continued to be used until 1993, when it was formally replaced with the Russi ...

Slonimski's Theorem
Slonimski's Theorem is an observation by Hayyim Selig Slonimski that the sequence of carry digits in a multiplication table is the Farey sequence In mathematics, the Farey sequence of order ''n'' is the sequence of completely reduced fractions, either between 0 and 1, or without this restriction, which have denominators less than or equal to ''n'', arranged in order of increasing size. Wi .... This observation allowed Slonimski to create very compact multiplication tables for use in hand calculations. He received several awards for different devices for presenting these tables. The most common format were Joffe Bars similar to Napier's Rods. Joffe Bars were popular in Eastern Europe in the late 19th and early 20th century. References *.

Photo Of Hayyim Selig Slonimski, Polin Museum
A photograph (also known as a photo, or more generically referred to as an ''image'' or ''picture'') is an image created by light falling on a photosensitivity, photosensitive surface, usually photographic film or an electronic image sensor. The process and practice of creating such images is called photography. Most photographs are now created using a smartphone or camera, which uses a photographic lens, lens to focus the scene's visible spectrum, visible wavelengths of light into a reproduction of what the human eye would perceive. Etymology The word ''photograph'' was coined in 1839 by Sir John Herschel and is based on the Greek language, Greek φῶς ('':el:phos, phos''), meaning "light", and γραφή (''graphê''), meaning "drawing, writing", together meaning "drawing with light". History The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the Bitumen of Judea, bitumen-based "heliography" process developed by Nicéphore Niép ...

Abraham Stern (inventor)
Abraham Jacob Stern (; 1762 or 1769 – 3 February 1842) was a Polish Jewish ''Haskalah, maskil'', inventor, educator, and poet. He is known for his mechanical calculators. Biography Abraham Stern was born in Hrubieszow to poor Jews, Jewish parents Miriam Liba () and Menachem Mendel Stern (). He received a traditional Cheder, Jewish education, and trained as a watchmaker. His natural aptitude in the study of philosophy, languages, and mathematics was discovered by reformer Stanisław Staszic, who invited him to Warsaw to continue his studies. His first major invention was a mechanical calculator, perfected in 1817, which could calculate the square roots of numbers. This attracted wide attention, and led to his being elected in 1817 the first Jewish member of the Warsaw Society of Friends of Learning, Warsaw Society of the Friends of Science. In 1816, and again in 1818, he was presented to Tsar Alexander I of Russia, Alexander I, who granted him an annual pension of 350 rubles fr ...
