Mechanics
Mechanics (from Ancient Greek: μηχανική, ''mēkhanikḗ'', "of machines") is the area of mathematics and physics concerned with the relationships between force, matter, and motion among physical objects. Forces applied to objects result in displacements, or changes of an object's position relative to its environment. Theoretical expositions of this branch of physics has its origins in Ancient Greece, for instance, in the writings of Aristotle and Archimedes (see History of classical mechanics and Timeline of classical mechanics). During the early modern period, scientists such as Galileo, Kepler, Huygens, and Newton laid the foundation for what is now known as classical mechanics. As a branch of classical physics, mechanics deals with bodies that are either at rest or are moving with velocities significantly less than the speed of light. It can also be defined as the physical science that deals with the motion of and forces on bodies not in the quantum realm ...

Pogroms In The Russian Empire
Pogroms in the Russian Empire (russian: Еврейские погромы в Российской империи) were large-scale, targeted, and repeated anti-Jewish rioting that began in the 19th century. Pogroms began to occur after Imperial Russia, which previously had very few Jews, acquired territories with large Jewish populations from the Polish–Lithuanian Commonwealth and the Ottoman Empire from 1772 to 1815. These territories were designated "the Pale of Settlement" by the Imperial Russian government, within which Jews were reluctantly permitted to live, and it was within them where the pogroms largely took place. Jews were forbidden from moving to other parts of European Russia (including Finland), unless they converted from Judaism or obtained a university diploma or first guild merchant status. Migration to the Caucasus, Siberia, the Far East or Central Asia was not restricted. 1821 The 1821 Odessa pogroms are sometimes considered the first pogroms. After the executi ...

Ha-Ẓefirah
''Ha-Tsfira'' ( he, הצפירה) was a Hebrew language, Hebrew-language newspaper published in Poland in 1862 and 1874–1931. History The first issue of ''Ha-Tsfira'' appeared in Warsaw, Congress Poland, in 1862, edited by Chaim Selig Slonimski. ''Ha-Tsfira'' was the first Hebrew paper with an emphasis on the sciences. The paper closed down after six months when Slonimski became principal of the rabbinical seminary in Zhytomyr, and the government began censorship of Hebrew books. It reopened in 1874 in Berlin, and began to be published in Warsaw in September 1875. Coverage of news and politics was introduced after the First Zionist Congress. From 1886, the paper began to appear as a daily. The driving spirit behind this change was Slonimski's assistant, Nachum Sokolov, who was later appointed editor-in-chief. ''Ha-Tsfira'' became part of a network of important Hebrew periodicals, among them ''Ha-Shahar'', ''Ha-Asif'', ''Ha-Shiloaḥ''. Some of the greatest names in early modern ...

Ha-Melitz
''Ha-Melitz'' or ''HaMelitz'' (Hebrew: ) was the first Hebrew newspaper in the Russian Empire. It was founded by Alexander Zederbaum in Odessa in 1860. History ''Ha-Melitz'' first appeared as a weekly, and it began to appear daily in 1886. From 1871, it was published in Saint Petersburg. Publication was suspended several times for lack of support or by order of the authorities. In 1893, Leon Rabinowitz succeeded Zederbaum as the editor. ''Ha-Melitz'' was a representative of the progressive or ''haskalah'' movement, and even so severe a critic as Abraham Kovner admitted that it had been "more useful to the Jews than have the other Hebrew newspapers" (''Ḥeḳer Dabar,'' p. 52 ff., Warsaw, 1866). While it was not so literary or scientific as some of its contemporaries, ''Ha-Melitz'' usually had more news and debates of interest, and was consequently more popular. J. A. Goldenblum was for many years associated with Zederbaum in its publication. Abraham Shalom Friedberg and Ju ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hebrew
Hebrew (; ; ) is a Northwest Semitic language of the Afroasiatic language family. Historically, it is one of the spoken languages of the Israelites and their longest-surviving descendants, the Jews and Samaritans. It was largely preserved throughout history as the main liturgical language of Judaism (since the Second Temple period) and Samaritanism. Hebrew is the only Canaanite language still spoken today, and serves as the only truly successful example of a dead language that has been revived. It is also one of only two Northwest Semitic languages still in use, with the other being Aramaic. The earliest examples of written Paleo-Hebrew date back to the 10th century BCE. Nearly all of the Hebrew Bible is written in Biblical Hebrew, with much of its present form in the dialect that scholars believe flourished around the 6th century BCE, during the time of the Babylonian captivity. For this reason, Hebrew has been referred to by Jews as '' Lashon Hakodesh'' (, ) since an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Munich
Munich ( ; german: München ; bar, Minga ) is the capital and most populous city of the States of Germany, German state of Bavaria.

Mishnat Ha-Middot
The Mishnat ha-Middot ( he, מִשְׁנַת הַמִּדּוֹת, 'Treatise of Measures') is the earliest known Hebrew treatise on geometry, composed of 49 ''mishnayot'' in six chapters. Scholars have dated the work to either the Mishnaic period or the early Islamic era. History Date of composition Moritz Steinschneider dated the ''Mishnat ha-Middot'' to between 800 and 1200 CE. Sarfatti and Langermann have advanced Steinschneider's claim of Arabic influence on the work's terminology, and date the text to the early ninth century. On the other hand, Hermann Schapira argued that the treatise dates from an earlier era, most likely the Mishnaic period, as its mathematical terminology differs from that of the Hebrew mathematicians of the Arab period. Solomon Gandz conjectured that the text was compiled no later than (possibly by Rabbi Nehemiah) and intended to be a part of the Mishnah, but was excluded from its final canonical edition because the work was regarded as too secular ...

Hebrew Literature
Hebrew literature consists of ancient, medieval, and modern writings in the Hebrew language. It is one of the primary forms of Jewish literature, though there have been cases of literature written in Hebrew by non-Jews. Hebrew literature was produced in many different parts of the world throughout the medieval and modern eras, while contemporary Hebrew literature is largely Israeli literature. In 1966, Agnon won the Nobel Prize for Literature for novels and short stories that employ a unique blend of biblical, Talmudic and modern Hebrew, making him the first Hebrew writer to receive this award. Ancient era Literature in Hebrew begins with the oral literature of the ' (), "The Holy Language", since ancient times and with the teachings of Abraham, the first of the biblical patriarchs of Israel, c. 2000 BCE . Beyond comparison, the most important work of ancient Hebrew literature is the Hebrew Bible (Tanakh). The Mishna, compiled around 200 CE, is the primary rabbinic codifica ...

Privatdozent
''Privatdozent'' (for men) or ''Privatdozentin'' (for women), abbreviated PD, P.D. or Priv.-Doz., is an academic title conferred at some European universities, especially in German-speaking countries, to someone who holds certain formal qualifications that denote an ability (''facultas docendi'') and permission to teach (''venia legendi'') a designated subject at the highest level. To be granted the title Priv.-Doz. by a university, a recipient has to fulfill the criteria set by the university which usually require excellence in research, teaching, and further education. In its current usage, the title indicates that the holder has completed their habilitation and is therefore granted permission to teach and examine students independently without having a professorship. Conferment and roles A university faculty can confer the title to an academic who has a higher doctoral degree - usually in the form of a habilitation. The title, ''Privatdozent'', as such does not imply a sala ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cofunction
In mathematics, a function ''f'' is cofunction of a function ''g'' if ''f''(''A'') = ''g''(''B'') whenever ''A'' and ''B'' are complementary angles. This definition typically applies to trigonometric functions. The prefix "co-" can be found already in Edmund Gunter's ''Canon triangulorum'' (1620). For example, sine (Latin: ''sinus'') and cosine (Latin: ''cosinus'', ''sinus complementi'') are cofunctions of each other (hence the "co" in "cosine"): The same is true of secant (Latin: ''secans'') and cosecant (Latin: ''cosecans'', ''secans complementi'') as well as of tangent (Latin: ''tangens'') and cotangent (Latin: ''cotangens'', ''tangens complementi''): These equations are also known as the cofunction identities. This also holds true for the versine (versed sine, ver) and coversine (coversed sine, cvs), the vercosine (versed cosine, vcs) and covercosine (coversed cosine, cvc), the haversine (half-versed sine, hav) and hacoversine (half-coversed sine, hcv), the havercosin ...

Homogeneous Function
In mathematics, a homogeneous function is a function of several variables such that, if all its arguments are multiplied by a scalar, then its value is multiplied by some power of this scalar, called the degree of homogeneity, or simply the ''degree''; that is, if is an integer, a function of variables is homogeneous of degree if :f(sx_1,\ldots, sx_n)=s^k f(x_1,\ldots, x_n) for every x_1, \ldots, x_n, and s\ne 0. For example, a homogeneous polynomial of degree defines a homogeneous function of degree . The above definition extends to functions whose domain and codomain are vector spaces over a field : a function f : V \to W between two -vector spaces is ''homogeneous'' of degree k if for all nonzero s \in F and v \in V. This definition is often further generalized to functions whose domain is not , but a cone in , that is, a subset of such that \mathbf\in C implies s\mathbf\in C for every nonzero scalar .
