148-563: Nisan (or Nissan ; Hebrew : נִיסָן , romanized : Nīsān from Akkadian : 𒁈 , romanized: Nissāni ) in the Babylonian and Hebrew calendars is the month of the barley ripening and first month of spring. The name of the month is an Akkadian language borrowing, although it ultimately originates in Sumerian nisag "first fruits". In the Hebrew calendar it is
296-492: A heliometer from Fraunhofer . The scientific activity of Gauss, besides pure mathematics, can be roughly divided into three periods: astronomy was the main focus in the first two decades of the 19th century, geodesy in the third decade, and physics, mainly magnetism, in the fourth decade. Gauss made no secret of his aversion to giving academic lectures. But from the start of his academic career at Göttingen, he continuously gave lectures until 1854. He often complained about
444-423: A magnetometer in 1833 and – alongside Wilhelm Eduard Weber – the first electromagnetic telegraph in 1833. Gauss was the first to discover and study non-Euclidean geometry , coining the term as well. He further developed a fast Fourier transform some 160 years before John Tukey and James Cooley . Gauss refused to publish incomplete work and left several works to be edited posthumously . He believed that
592-685: A Hebrew form. Medieval Hebrew added 6421 words to (Modern) Hebrew. The approximate number of new lexical items in Israeli is 17,000 (cf. 14,762 in Even-Shoshan 1970 [...]). With the inclusion of foreign and technical terms [...], the total number of Israeli words, including words of biblical, rabbinic and medieval descent, is more than 60,000. In Israel, Modern Hebrew is currently taught in institutions called Ulpanim (singular: Ulpan). There are government-owned, as well as private, Ulpanim offering online courses and face-to-face programs. Modern Hebrew
740-406: A butcher, bricklayer, gardener, and treasurer of a death-benefit fund. Gauss characterized his father as honourable and respected, but rough and dominating at home. He was experienced in writing and calculating, whereas his second wife Dorothea, Carl Friedrich's mother, was nearly illiterate. He had one elder brother from his father's first marriage. Gauss was a child prodigy in mathematics. When

Hebrew has been revived several times as a literary language, most significantly by the Haskalah (Enlightenment) movement of early and mid-19th-century Germany. In the early 19th century, a form of spoken Hebrew had emerged in the markets of Jerusalem between Jews of different linguistic backgrounds to communicate for commercial purposes. This Hebrew dialect
1036-569: A collection of short remarks about his results from the years 1796 until 1814, shows that many ideas for his mathematical magnum opus Disquisitiones Arithmeticae (1801) date from this time. Gauss graduated as a Doctor of Philosophy in 1799, not in Göttingen, as is sometimes stated, but at the Duke of Brunswick's special request from the University of Helmstedt, the only state university of
1184-491: A considerable literary estate, too. Gauss referred to mathematics as "the queen of sciences" and arithmetics as "the queen of mathematics", and supposedly once espoused a belief in the necessity of immediately understanding Euler's identity as a benchmark pursuant to becoming a first-class mathematician. On certain occasions, Gauss claimed that the ideas of another scholar had already been in his possession previously. Thus his concept of priority as "the first to discover, not
1332-661: A corollary Hebrew ceased to function as a spoken language around the same time. Moshe Zvi Segal , Joseph Klausner and Ben Yehuda are notable exceptions to this view. During the latter half of the 20th century, accumulating archaeological evidence and especially linguistic analysis of the Dead Sea Scrolls has disproven that view. The Dead Sea Scrolls, uncovered in 1946–1948 near Qumran revealed ancient Jewish texts overwhelmingly in Hebrew, not Aramaic. The Qumran scrolls indicate that Hebrew texts were readily understandable to
1480-672: A critique of d'Alembert's work. He subsequently produced three other proofs, the last one in 1849 being generally rigorous. His attempts clarified the concept of complex numbers considerably along the way. In the preface to the Disquisitiones , Gauss dates the beginning of his work on number theory to 1795. By studying the works of previous mathematicians like Fermat, Euler, Lagrange, and Legendre, he realized that these scholars had already found much of what he had discovered by himself. The Disquisitiones Arithmeticae , written since 1798 and published in 1801, consolidated number theory as
1628-431: A curious feature of his working style that he carried out calculations with a high degree of precision much more than required, and prepared tables with more decimal places than ever requested for practical purposes. Very likely, this method gave him a lot of material which he used in finding theorems in number theory. Gauss refused to publish work that he did not consider complete and above criticism. This perfectionism

Her sister Wilhelmina married the orientalist Heinrich Ewald . Gauss's mother Dorothea lived in his house from 1817 until she died in 1839. The eldest son Joseph, while still a schoolboy, helped his father as an assistant during the survey campaign in
1924-483: A discipline and covered both elementary and algebraic number theory . Therein he introduces the triple bar symbol ( ≡ ) for congruence and uses it for a clean presentation of modular arithmetic . It deals with the unique factorization theorem and primitive roots modulo n . In the main sections, Gauss presents the first two proofs of the law of quadratic reciprocity and develops the theories of binary and ternary quadratic forms . The Disquisitiones include
2072-579: A distinct style of philosophical Hebrew. This is used in the translations made by the Ibn Tibbon family. (Original Jewish philosophical works were usually written in Arabic. ) Another important influence was Maimonides , who developed a simple style based on Mishnaic Hebrew for use in his law code, the Mishneh Torah . Subsequent rabbinic literature is written in a blend between this style and
2220-594: A gradually accepted movement. It was not, however, until the 1904–1914 Second Aliyah that Hebrew had caught real momentum in Ottoman Palestine with the more highly organized enterprises set forth by the new group of immigrants. When the British Mandate of Palestine recognized Hebrew as one of the country's three official languages (English, Arabic, and Hebrew, in 1922), its new formal status contributed to its diffusion. A constructed modern language with

Similar to his excellent knowledge of Latin he was also acquainted with modern languages. At the age of 62, he began to teach himself Russian , very likely to understand scientific writings from Russia, among them those of Lobachevsky on non-Euclidean geometry. Gauss read both classical and modern literature, and English and French works in
2516-555: A heart attack in Göttingen; and was interred in the Albani Cemetery there. Heinrich Ewald , Gauss's son-in-law, and Wolfgang Sartorius von Waltershausen , Gauss's close friend and biographer, gave eulogies at his funeral. Gauss was a successful investor and accumulated considerable wealth with stocks and securities, finally a value of more than 150 thousand Thaler; after his death, about 18 thousand Thaler were found hidden in his rooms. The day after Gauss's death his brain
2664-468: A literary language down through the Byzantine period from the 4th century CE. The exact roles of Aramaic and Hebrew remain hotly debated. A trilingual scenario has been proposed for the land of Israel. Hebrew functioned as the local mother tongue with powerful ties to Israel's history, origins and golden age and as the language of Israel's religion; Aramaic functioned as the international language with
2812-536: A literary language, especially in Spain, as the language of commerce between Jews of different native languages, and as the liturgical language of Judaism, evolving various dialects of literary Medieval Hebrew , until its revival as a spoken language in the late 19th century. In May 2023, Scott Stripling published the finding of what he claims to be the oldest known Hebrew inscription, a curse tablet found at Mount Ebal , dated from around 3200 years ago. The presence of
2960-474: A private scholar. He gave the second and third complete proofs of the fundamental theorem of algebra , made contributions to number theory , and developed the theories of binary and ternary quadratic forms. Gauss was instrumental in the identification of Ceres as a dwarf planet. His work on the motion of planetoids disturbed by large planets led to the introduction of the Gaussian gravitational constant and
3108-702: A scandal in public, Eugen suddenly left Göttingen under dramatic circumstances in September 1830 and emigrated via Bremen to the United States. He wasted the little money he had taken to start, after which his father refused further financial support. The youngest son Wilhelm wanted to qualify for agricultural administration, but had difficulties getting an appropriate education, and eventually emigrated as well. Only Gauss's youngest daughter Therese accompanied him in his last years of life. Collecting numerical data on very different things, useful or useless, became

#17327725277083256-548: A set of dialects evolving out of Late Biblical Hebrew and into Mishnaic Hebrew, thus including elements from both but remaining distinct from either. By the start of the Byzantine Period in the 4th century CE, Classical Hebrew ceased as a regularly spoken language, roughly a century after the publication of the Mishnah, apparently declining since the aftermath of the catastrophic Bar Kokhba revolt around 135 CE. In
3404-668: A spoken language, it continued to be used as a lingua franca among scholars and Jews traveling in foreign countries. After the 2nd century CE when the Roman Empire exiled most of the Jewish population of Jerusalem following the Bar Kokhba revolt , they adapted to the societies in which they found themselves, yet letters, contracts, commerce, science, philosophy, medicine, poetry and laws continued to be written mostly in Hebrew, which adapted by borrowing and inventing terms. After

At university, he was accompanied by a staff of other lecturers in his disciplines, who completed the educational program; these included the mathematician Thibaut with his lectures, the physicist Mayer , known for his textbooks, his successor Weber since 1831, and in the observatory Harding , who took the main part of lectures in practical astronomy. When

While many saw his work as fanciful or even blasphemous (because Hebrew was the holy language of the Torah and therefore some thought that it should not be used to discuss everyday matters), many soon understood the need for a common language amongst Jews of
3848-445: A university chair in Göttingen, "because he was always involved in some polemic." Gauss's life was overshadowed by severe problems in his family. When his first wife Johanna suddenly died shortly after the birth of their third child, he revealed the grief in a last letter to his dead wife in the style of an ancient threnody , the most personal surviving document of Gauss. The situation worsened when tuberculosis ultimately destroyed
3996-558: A vernacular in Judea until it was displaced by Aramaic, probably in the 3rd century CE. Certain Sadducee , Pharisee , Scribe , Hermit, Zealot and Priest classes maintained an insistence on Hebrew, and all Jews maintained their identity with Hebrew songs and simple quotations from Hebrew texts. While there is no doubt that at a certain point, Hebrew was displaced as the everyday spoken language of most Jews, and that its chief successor in

A regional dialect of the Canaanite languages , it was natively spoken by the Israelites and remained in regular use as a first language until after 200 CE and as the liturgical language of Judaism (since the Second Temple period ) and Samaritanism . The language was revived as a spoken language in the 19th century, and

In 2012, a Knesset bill for the preservation of the Hebrew language was proposed, which includes the stipulation that all signage in Israel must first and foremost be in Hebrew, as with all speeches by Israeli officials abroad. The bill's author, MK Akram Hasson , stated that the bill was proposed as a response to Hebrew "losing its prestige" and children incorporating more English words into their vocabulary. Hebrew

Currently, 90% of Israeli Jews are proficient in Hebrew, and 70% are highly proficient. Some 60% of Israeli Arabs are also proficient in Hebrew, and 30% report having a higher proficiency in Hebrew than in Arabic. In total, about 53% of

It is traditionally understood to be an adjective based on the name of Abraham 's ancestor, Eber , mentioned in Genesis 10:21 . The name is believed to be based on the Semitic root ʕ-b-r ( ע־ב־ר ), meaning "beyond", "other side", "across"; interpretations of
5624-547: The Canaanite group of languages . Canaanite languages are a branch of the Northwest Semitic family of languages. Hebrew was the spoken language in the Iron Age kingdoms of Israel and Judah during the period from about 1200 to 586 BCE. Epigraphic evidence from this period confirms the widely accepted view that the earlier layers of biblical literature reflect the language used in these kingdoms. Furthermore,

They assembled data on asteroids and comets as a basis for Gauss's research on their orbits, which he later published in his astronomical magnum opus Theoria motus corporum coelestium (1809). In November 1807, Gauss followed a call to the University of Göttingen , then an institution of the newly founded Kingdom of Westphalia under Jérôme Bonaparte , as full professor and director of

However, his brand of Hebrew followed norms that had been replaced in Eastern Europe by different grammar and style, in the writings of people like Ahad Ha'am and others. His organizational efforts and involvement with the establishment of schools and the writing of textbooks pushed the vernacularization activity into
6956-472: The method of least squares , which he had discovered before Adrien-Marie Legendre published it. Gauss was in charge of the extensive geodetic survey of the Kingdom of Hanover together with an arc measurement project from 1820 to 1844; he was one of the founders of geophysics and formulated the fundamental principles of magnetism . Fruits of his practical work were the inventions of the heliotrope in 1821,

After Israel, the United States has the largest Hebrew-speaking population, with approximately 220,000 fluent speakers (see Israeli Americans and Jewish Americans ). Modern Hebrew is the official language of the State of Israel, while pre-revival forms of Hebrew are used for prayer or study in Jewish and Samaritan communities around

In its widest sense, Biblical Hebrew refers to the spoken language of ancient Israel flourishing between c. 1000 BCE and c. 400 CE . It comprises several evolving and overlapping dialects. The phases of Classical Hebrew are often named after important literary works associated with them. Sometimes

Several of the teachers were imprisoned, e.g. Yosef Begun , Ephraim Kholmyansky , Yevgeny Korostyshevsky and others responsible for a Hebrew learning network connecting many cities of the USSR. Standard Hebrew, as developed by Eliezer Ben-Yehuda, was based on Mishnaic spelling and Sephardi Hebrew pronunciation. However,
7844-611: The 19th century was a lexical modernization of Hebrew. New words and expressions were adapted as neologisms from the large corpus of Hebrew writings since the Hebrew Bible, or borrowed from Arabic (mainly by Ben-Yehuda) and older Aramaic and Latin. Many new words were either borrowed from or coined after European languages, especially English, Russian, German, and French. Modern Hebrew became an official language in British-ruled Palestine in 1921 (along with English and Arabic), and then in 1948 became an official language of

' Judean ' ) or Səpaṯ Kəna'an ( transl. "the language of Canaan " ). Mishnah Gittin 9:8 refers to
8140-766: The Aramaized Rabbinic Hebrew of the Talmud. Hebrew persevered through the ages as the main language for written purposes by all Jewish communities around the world for a large range of uses—not only liturgy, but also poetry, philosophy, science and medicine, commerce, daily correspondence and contracts. There have been many deviations from this generalization such as Bar Kokhba 's letters to his lieutenants, which were mostly in Aramaic, and Maimonides' writings, which were mostly in Arabic; but overall, Hebrew did not cease to be used for such purposes. For example,

In 20874 CE, therefore, the Jewish year is due to begin at 11.30 3/18 A.M. on Friday, 14 June. Because of the displacements, it actually begins on Saturday, 15 June. Odd months have 30 days and even months 29, so the starting dates are 2, 15 July; 3, 13 August; 4, 12 September; 5, 11 October; 6, 10 November; 7, 9 December, and 8, 8 January. The rules are based on

Allowing for the current difference of thirteen days between the civil and Julian calendars, the Julian date is 13+(248x0d 5h 47 4/18m) earlier, which is 72d 21h 28 16/18m earlier. Convert back to the civil calendar by applying the formula. So, in 20874 CE,

Gauss confessed to disliking teaching, but some of his students became influential mathematicians, such as Richard Dedekind and Bernhard Riemann . Gauss was born on 30 April 1777 in Brunswick in the Duchy of Brunswick-Wolfenbüttel (now in the German state of Lower Saxony ). His family was of relatively low social status. His father Gebhard Dietrich Gauss (1744–1808) worked variously as
10804-506: The average Jew, and that the language had evolved since Biblical times as spoken languages do. Recent scholarship recognizes that reports of Jews speaking in Aramaic indicate a multilingual society, not necessarily the primary language spoken. Alongside Aramaic, Hebrew co-existed within Israel as a spoken language. Most scholars now date the demise of Hebrew as a spoken language to the end of the Roman period , or about 200 CE. It continued on as
10952-547: The beginning of the 20th century, Hebrew was well on its way to becoming the main language of the Jewish population of both Ottoman and British Palestine. At the time, members of the Old Yishuv and a very few Hasidic sects, most notably those under the auspices of Satmar , refused to speak Hebrew and spoke only Yiddish. In the Soviet Union, the use of Hebrew, along with other Jewish cultural and religious activities,
11100-637: The best-paid professors of the university. When Gauss was asked for help by his colleague and friend Friedrich Wilhelm Bessel in 1810, who was in trouble at Königsberg University because of his lack of an academic title, Gauss provided a doctorate honoris causa for Bessel from the Philosophy Faculty of Göttingen in March 1811. Gauss gave another recommendation for an honorary degree for Sophie Germain but only shortly before her death, so she never received it. He also gave successful support to
11248-517: The birth of Louis, who himself died a few months later. Gauss chose the first names of his children in honour of Giuseppe Piazzi , Wilhelm Olbers, and Karl Ludwig Harding, the discoverers of the first asteroids. On 4 August 1810, Gauss married Wilhelmine (Minna) Waldeck, a friend of his first wife, with whom he had three more children: Eugen (later Eugene) (1811–1896), Wilhelm (later William) (1813–1879), and Therese (1816–1864). Minna Gauss died on 12 September 1831 after being seriously ill for more than
11396-701: The burdens of teaching, feeling that it was a waste of his time. On the other hand, he occasionally described some students as talented. Most of his lectures dealt with astronomy, geodesy, and applied mathematics , and only three lectures on subjects of pure mathematics. Some of Gauss's students went on to become renowned mathematicians, physicists, and astronomers: Moritz Cantor , Dedekind , Dirksen , Encke , Gould , Heine , Klinkerfues , Kupffer , Listing , Möbius , Nicolai , Riemann , Ritter , Schering , Scherk , Schumacher , von Staudt , Stern , Ursin ; as geoscientists Sartorius von Waltershausen , and Wappäus . Gauss did not write any textbook and disliked
11544-405: The calculated value applies on and from 1 March (civil date) for conversions to Julian. For earlier dates reduce the calculated value by one. For conversions to the civil date the calculated value applies on and from 29 February (Julian date). Again, for earlier dates reduce the calculated value by one. The difference is applied to the calendar one is converting into . A negative value indicates that
11692-602: The composition of 1 Maccabees in archaizing Hebrew, Hasmonean coinage under John Hyrcanus (134-104 BCE), and coins from both the Great Revolt and Bar Kokhba Revolt featuring exclusively Hebrew and Palaeo-Hebrew script inscriptions. This deliberate use of Hebrew and Paleo-Hebrew script in official contexts, despite limited literacy, served as a symbol of Jewish nationalism and political independence. The Christian New Testament contains some Semitic place names and quotes. The language of such Semitic glosses (and in general
11840-496: The contemporary school of Naturphilosophie . Gauss had an "aristocratic and through and through conservative nature", with little respect for people's intelligence and morals, following the motto " mundus vult decipi ". He disliked Napoleon and his system, and all kinds of violence and revolution caused horror to him. Thus he condemned the methods of the Revolutions of 1848 , though he agreed with some of their aims, such as
11988-410: The content of Hebrew inscriptions suggests that the written texts closely mirror the spoken language of that time. Scholars debate the degree to which Hebrew was a spoken vernacular in ancient times following the Babylonian exile when the predominant international language in the region was Old Aramaic . Hebrew was extinct as a colloquial language by late antiquity , but it continued to be used as
12136-409: The date will be later by the number of days which corresponds to the difference between the actual number of insertions and five. If the year is due to start on Sunday, it actually begins on the following Tuesday if the following year is due to start on Friday morning. If due to start on Monday, Wednesday or Friday it actually begins on the following day. If due to start on Saturday, it actually begins on
12284-531: The day of the Jewish month to within a day or so and the number of the month to within a month or so. From the 4th century, the number of the month is given exactly and from the 9th century the day of the month is given exactly as well. In the Julian calendar, every 76 years the Jewish year is due to start 5h 47 14/18m earlier, and 3d 18h 12 4/18m later in the week. On what civil date does the eighth month begin in CE 20874–5? 20874=2026+(248x76). In (248x76) Julian years
12432-568: The dialects of Classical Hebrew that functioned as a living language in the land of Israel. A transitional form of the language occurs in the other works of Tannaitic literature dating from the century beginning with the completion of the Mishnah. These include the halachic Midrashim ( Sifra , Sifre , Mekhilta etc.) and the expanded collection of Mishnah-related material known as the Tosefta . The Talmud contains excerpts from these works, as well as further Tannaitic material not attested elsewhere;
12580-702: The duchy. Johann Friedrich Pfaff assessed his doctoral thesis, and Gauss got the degree in absentia without further oral examination. The Duke then granted him the cost of living as a private scholar in Brunswick. Gauss subsequently refused calls from the Russian Academy of Sciences in St. Peterburg and Landshut University . Later, the Duke promised him the foundation of an observatory in Brunswick in 1804. Architect Peter Joseph Krahe made preliminary designs, but one of Napoleon's wars cancelled those plans:
12728-423: The earliest Hebrew writing yet discovered, dating from around 3,000 years ago. Hebrew University archaeologist Amihai Mazar said that the inscription was "proto-Canaanite" but cautioned that "[t]he differentiation between the scripts, and between the languages themselves in that period, remains unclear", and suggested that calling the text Hebrew might be going too far. The Gezer calendar also dates back to
12876-513: The earliest speakers of Modern Hebrew had Yiddish as their native language and often introduced calques from Yiddish and phono-semantic matchings of international words. Despite using Sephardic Hebrew pronunciation as its primary basis, modern Israeli Hebrew has adapted to Ashkenazi Hebrew phonology in some respects, mainly the following: The vocabulary of Israeli Hebrew is much larger than that of earlier periods. According to Ghil'ad Zuckermann : The number of attested Biblical Hebrew words
13024-532: The early 6th century BCE, the Neo-Babylonian Empire conquered the ancient Kingdom of Judah , destroying much of Jerusalem and exiling its population far to the east in Babylon . During the Babylonian captivity , many Israelites learned Aramaic, the closely related Semitic language of their captors. Thus, for a significant period, the Jewish elite became influenced by Aramaic. After Cyrus
13172-514: The elementary teachers noticed his intellectual abilities, they brought him to the attention of the Duke of Brunswick who sent him to the local Collegium Carolinum , which he attended from 1792 to 1795 with Eberhard August Wilhelm von Zimmermann as one of his teachers. Thereafter the Duke granted him the resources for studies of mathematics, sciences, and classical languages at the University of Göttingen until 1798. His professor in mathematics
13320-412: The end of the fifth section, it appears that Gauss already knew the class number formula in 1801. In the last section, Gauss gives proof for the constructibility of a regular heptadecagon (17-sided polygon) with straightedge and compass by reducing this geometrical problem to an algebraic one. He shows that a regular polygon is constructible if the number of its sides is either a power of 2 or
13468-406: The equivalent lunar months in the Babylonian calendar came to be applied to the Hebrew calendar during the Babylonian captivity , in which the month of Aviv's name was Araḫ Nissānu , the "month of beginning". The list below gives a time which can be used to determine the day the Jewish ecclesiastical (spring) year starts over a period of nineteen years. These are not Nisan molad times, although
13616-711: The first Middle East printing press, in Safed (modern Israel), produced a small number of books in Hebrew in 1577, which were then sold to the nearby Jewish world. This meant not only that well-educated Jews in all parts of the world could correspond in a mutually intelligible language, and that books and legal documents published or written in any part of the world could be read by Jews in all other parts, but that an educated Jew could travel and converse with Jews in distant places, just as priests and other educated Christians could converse in Latin. For example, Rabbi Avraham Danzig wrote
13764-429: The first and seventh simultaneously, and are referred to as one or the other depending on the specific religious aspects being discussed. The biblical Hebrew months were given enumerations instead of names. The new moon of Aviv , which in Hebrew means "barley ripening" and by extension "spring season"(Exodus 9:31) is one of the few called both by name and by its number, the first. Nisan and other Akkadian-origin names for
13912-669: The first investigations, due to mislabelling, with that of the physician Conrad Heinrich Fuchs , who died in Göttingen a few months after Gauss. A further investigation showed no remarkable anomalies in the brains of both persons. Thus, all investigations on Gauss's brain until 1998, except the first ones of Rudolf and Hermann Wagner, actually refer to the brain of Fuchs. Gauss married Johanna Osthoff on 9 October 1805 in St. Catherine's church in Brunswick. They had two sons and one daughter: Joseph (1806–1873), Wilhelmina (1808–1840), and Louis (1809–1810). Johanna died on 11 October 1809, one month after
14060-545: The first month of the ecclesiastical year, called the "first of the months of the year" ( Exodus 12 :1-2), "first month" (Ex 12:14), and the month of Aviv (Ex 13:4) בְּחֹ֖דֶשׁ הָאָבִֽיב ḥōḏeš hāʾāḇîḇ ). It is called Nissān in the Book of Esther . It is a month of 30 days. In the year 2024, 1 Nisan will occur on 9 April. Counting from 1 Tishrei , the civil new year, it would be the seventh month (eighth, in leap year), but in contemporary Jewish culture, both months are viewed as
14208-440: The first to publish" differed from that of his scientific contemporaries. In contrast to his perfectionism in presenting mathematical ideas, he was criticized for a negligent way of quoting. He justified himself with a very special view of correct quoting: if he gave references, then only in a quite complete way, with respect to the previous authors of importance, which no one should ignore; but quoting in this way needed knowledge of
14356-427: The following day if the previous year was due to begin on Monday morning. The table below lists, for a Jewish year commencing on 23 March, the civil date of the first day of each month. If the year does not begin on 23 March, each month's first day will differ from the date shown by the number of days that the start of the year differs from 23 March. The correct column is the one which shows the correct starting date for
14504-530: The following year in the last row. If 29 February falls within a Jewish month the first day of later months will be a day earlier than shown. For long period calculations, dates should be reduced to the Julian calendar and converted back to the civil calendar at the end of the calculation. The civil calendar used here (Exigian) is correct to one day in 44,000 years and omits the leap day in centennial years which do not give remainder 200 or 700 when divided by 900. It
14652-406: The generic term for these passages is Baraitot . The dialect of all these works is very similar to Mishnaic Hebrew. About a century after the publication of the Mishnah, Mishnaic Hebrew fell into disuse as a spoken language. By the third century CE, sages could no longer identify the Hebrew names of many plants mentioned in the Mishnah. Only a few sages, primarily in the southern regions, retained
14800-525: The health of his second wife Minna over 13 years; both his daughters later suffered from the same disease. Gauss himself gave only slight hints of his distress: in a letter to Bessel dated December 1831 he described himself as "the victim of the worst domestic sufferings". By reason of his wife's illness, both younger sons were educated for some years in Celle , far from Göttingen. The military career of his elder son Joseph ended after more than two decades with
14948-460: The history of science and more time than he wished to spend. Soon after Gauss's death, his friend Sartorius published the first biography (1856), written in a rather enthusiastic style. Sartorius saw him as a serene and forward-striving man with childlike modesty, but also of "iron character" with an unshakeable strength of mind. Apart from his closer circle, others regarded him as reserved and unapproachable "like an Olympian sitting enthroned on
15096-467: The idea of a unified Germany. As far as the political system is concerned, he had a low estimation of the constitutional system; he criticized parliamentarians of his time for a lack of knowledge and logical errors. Some Gauss biographers have speculated on his religious beliefs. He sometimes said "God arithmetizes" and "I succeeded – not on account of my hard efforts, but by the grace of the Lord." Gauss
15244-462: The language as Ivrit , meaning Hebrew; however, Mishnah Megillah refers to the language as Ashurit , meaning Assyrian , which is derived from the name of the alphabet used , in contrast to Ivrit , meaning the Paleo-Hebrew alphabet . Hebrew ceased to be a regular spoken language sometime between 200 and 400 CE, as it declined in the aftermath of the unsuccessful Bar Kokhba revolt , which
15392-465: The language spoken by Jews in scenes from the New Testament) is often referred to as "Hebrew" in the text, although this term is often re-interpreted as referring to Aramaic instead and is rendered accordingly in recent translations. Nonetheless, these glosses can be interpreted as Hebrew as well. It has been argued that Hebrew, rather than Aramaic or Koine Greek, lay behind the composition of
15540-471: The language. The revival of the Hebrew language as a mother tongue was initiated in the late 19th century by the efforts of Ben-Yehuda. He joined the Jewish national movement and in 1881 immigrated to Palestine , then a part of the Ottoman Empire . Motivated by the surrounding ideals of renovation and rejection of the diaspora " shtetl " lifestyle, Ben-Yehuda set out to develop tools for making
15688-598: The mathematician Gotthold Eisenstein in Berlin. Gauss was loyal to the House of Hanover . After King William IV died in 1837, the new Hanoverian King Ernest Augustus annulled the 1833 constitution. Seven professors, later known as the " Göttingen Seven ", protested against this, among them his friend and collaborator Wilhelm Weber and Gauss's son-in-law Heinrich Ewald. All of them were dismissed, and three of them were expelled, but Ewald and Weber could stay in Göttingen. Gauss
15836-727: The newly declared State of Israel . Hebrew is the most widely spoken language in Israel today. In the Modern Period, from the 19th century onward, the literary Hebrew tradition revived as the spoken language of modern Israel, called variously Israeli Hebrew , Modern Israeli Hebrew , Modern Hebrew , New Hebrew , Israeli Standard Hebrew , Standard Hebrew and so on. Israeli Hebrew exhibits some features of Sephardic Hebrew from its local Jerusalemite tradition but adapts it with numerous neologisms, borrowed terms (often technical) from European languages and adopted terms (often colloquial) from Arabic. The literary and narrative use of Hebrew
15984-590: The observatory was completed, Gauss took his living accommodation in the western wing of the new observatory and Harding in the eastern one. They had once been on friendly terms, but over time they became alienated, possibly – as some biographers presume – because Gauss had wished the equal-ranked Harding to be no more than his assistant or observer. Gauss used the new meridian circles nearly exclusively, and kept them away from Harding, except for some very seldom joint observations. Brendel subdivides Gauss's astronomic activity chronologically into seven periods, of which
16132-405: The offset necessarily remains constant. (The fractions shown are fractions of a minute.) Every nineteen years this time is 2 days, 16 hours, 33 1/18 minutes later in the week. That is either the same or the previous day in the civil calendar, depending on whether the difference in the day of the week is three or two days. If 29 February is included fewer than five times in the nineteen – year period
16280-411: The original languages. His favorite English author was Walter Scott , his favorite German Jean Paul . Gauss liked singing and went to concerts. He was a busy newspaper reader; in his last years, he used to visit an academic press salon of the university every noon. Gauss did not care much for philosophy, and mocked the "splitting hairs of the so-called metaphysicians", by which he meant proponents of
16428-534: The phonetic values are instead inspired by the acrophonic principle. The common ancestor of Hebrew and Phoenician is called Canaanite , and was the first to use a Semitic alphabet distinct from that of Egyptian. One ancient document is the famous Moabite Stone , written in the Moabite dialect; the Siloam inscription , found near Jerusalem , is an early example of Hebrew. Less ancient samples of Archaic Hebrew include
16576-591: The present day. It is perhaps the most important Hebrew manuscript in existence. During the Golden age of Jewish culture in Spain , important work was done by grammarians in explaining the grammar and vocabulary of Biblical Hebrew; much of this was based on the work of the grammarians of Classical Arabic . Important Hebrew grammarians were Judah ben David Hayyuj , Jonah ibn Janah , Abraham ibn Ezra and later (in Provence ), David Kimhi . A great deal of poetry
16724-570: The primary language of use, and to prevent large-scale incorporation of English words into the Hebrew vocabulary. The Academy of the Hebrew Language of the Hebrew University of Jerusalem currently invents about 2,000 new Hebrew words each year for modern words by finding an original Hebrew word that captures the meaning, as an alternative to incorporating more English words into Hebrew vocabulary. The Haifa municipality has banned officials from using English words in official documents, and
16872-475: The problem by accepting offers from Berlin in 1810 and 1825 to become a full member of the Prussian Academy without burdening lecturing duties, as well as from Leipzig University in 1810 and from Vienna University in 1842, perhaps because of the family's difficult situation. Gauss's salary was raised from 1000 Reichsthaler in 1810 to 2400 Reichsthaler in 1824, and in his later years he was one of
17020-425: The product of a power of 2 and any number of distinct Fermat primes . In the same section, he gives a result on the number of solutions of certain cubic polynomials with coefficients in finite fields , which amounts to counting integral points on an elliptic curve . An unfinished eighth chapter was found among left papers only after his death, consisting of work done during 1797–1799. One of Gauss's first results
17168-592: The railroad system in the US for some months. Eugen left Göttingen in September 1830 and emigrated to the United States, where he joined the army for five years. He then worked for the American Fur Company in the Midwest. Later, he moved to Missouri and became a successful businessman. Wilhelm married a niece of the astronomer Bessel ; he then moved to Missouri, started as a farmer and became wealthy in
17316-437: The rank of a poorly paid first lieutenant , although he had acquired a considerable knowledge of geodesy. He needed financial support from his father even after he was married. The second son Eugen shared a good measure of his father's talent in computation and languages, but had a vivacious and sometimes rebellious character. He wanted to study philology, whereas Gauss wanted him to become a lawyer. Having run up debts and caused
17464-435: The reader the author's train of thought. Gauss was the first to restore that rigor of demonstration which we admire in the ancients and which had been forced unduly into the background by the exclusive interest of the preceding period in new developments. But for himself, he propagated a quite different ideal, given in a letter to Farkas Bolyai as follows: It is not knowledge, but the act of learning, not possession but
17612-674: The rest of the Middle East; and eventually Greek functioned as another international language with the eastern areas of the Roman Empire. William Schniedewind argues that after waning in the Persian period, the religious importance of Hebrew grew in the Hellenistic and Roman periods, and cites epigraphical evidence that Hebrew survived as a vernacular language – though both its grammar and its writing system had been substantially influenced by Aramaic. According to another summary, Greek
17760-411: The results by masterly estimation. Nevertheless, his calculations were not always free from mistakes. He coped with the enormous workload by using skillful tools. Gauss used a lot of mathematical tables , examined their exactness, and constructed new tables on various matters for personal use. He developed new tools for effective calculation, for example the Gaussian elimination . It has been taken as
17908-613: The shoe business in St. Louis in later years. Eugene and William have numerous descendants in America, but the Gauss descendants left in Germany all derive from Joseph, as the daughters had no children. In the first two decades of the 19th century, Gauss was the only important mathematician in Germany, comparable to the leading French ones; his Disquisitiones Arithmeticae was the first mathematical book from Germany to be translated into
18056-493: The southern villages of Judea." In other words, "in terms of dialect geography, at the time of the tannaim Palestine could be divided into the Aramaic-speaking regions of Galilee and Samaria and a smaller area, Judaea, in which Rabbinic Hebrew was used among the descendants of returning exiles." In addition, it has been surmised that Koine Greek was the primary vehicle of communication in coastal cities and among
18204-474: The spoken language of the Russian Jews, should be treated as their only national language, while Hebrew was to be treated as a foreign language. Hebrew books and periodicals ceased to be published and were seized from the libraries, although liturgical texts were still published until the 1930s. Despite numerous protests, a policy of suppression of the teaching of Hebrew operated from the 1930s on. Later in
18352-567: The sum. Gauss took on the directorate of the 60-year-old observatory, founded in 1748 by Prince-elector George II and built on a converted fortification tower, with usable, but partly out-of-date instruments. The construction of a new observatory had been approved by Prince-elector George III in principle since 1802, and the Westphalian government continued the planning, but Gauss could not move to his new place of work until September 1816. He got new up-to-date instruments, including two meridian circles from Repsold and Reichenbach , and
18500-577: The summer of 1821. After a short time at university, in 1824 Joseph joined the Hanoverian army and assisted in surveying again in 1829. In the 1830s he was responsible for the enlargement of the survey network to the western parts of the kingdom. With his geodetical qualifications, he left the service and engaged in the construction of the railway network as director of the Royal Hanoverian State Railways . In 1836 he studied
18648-421: The summit of science". His close contemporaries agreed that Gauss was a man of difficult character. He often refused to accept compliments. His visitors were occasionally irritated by his grumpy behaviour, but a short time later his mood could change, and he would become a charming, open-minded host. Gauss abominated polemic natures; together with his colleague Hausmann he opposed to a call for Justus Liebig on
18796-470: The term "Hebrew" generally render its meaning as roughly "from the other side [of the river/desert]"—i.e., an exonym for the inhabitants of the land of Israel and Judah , perhaps from the perspective of Mesopotamia , Phoenicia or Transjordan (with the river referred to being perhaps the Euphrates , Jordan or Litani ; or maybe the northern Arabian Desert between Babylonia and Canaan ). Compare
18944-519: The theory that Maimonides explains in his book Rabbinical Astronomy . The times in the list are those calculated by Gauss with an offset of -14 days as his calculation gives the civil date of Passover rather than the start of the month. Gauss's calculation has been rigorously proved. Hebrew language Hebrew ( Hebrew alphabet : עִבְרִית , ʿĪvrīt , pronounced [ ʔivˈʁit ] or [ ʕivˈrit ] ; Samaritan script : ࠏࠨࠁࠬࠓࠪࠉࠕ ʿÎbrit )
19092-580: The upper class of Jerusalem , while Aramaic was prevalent in the lower class of Jerusalem, but not in the surrounding countryside. After the suppression of the Bar Kokhba revolt in the 2nd century CE, Judaeans were forced to disperse. Many relocated to Galilee, so most remaining native speakers of Hebrew at that last stage would have been found in the north. Many scholars have pointed out that Hebrew continued to be used alongside Aramaic during Second Temple times, not only for religious purposes but also for nationalistic reasons, especially during revolts such as
19240-455: The word Habiru or cognate Assyrian ebru , of identical meaning. One of the earliest references to the language's name as " Ivrit " is found in the prologue to the Book of Sirach , from the 2nd century BCE. The Hebrew Bible does not use the term "Hebrew" in reference to the language of the Hebrew people; its later historiography, in the Book of Kings , refers to it as יְהוּדִית Yehudit " Judahite (language)". Hebrew belongs to
19388-595: The world today; the latter group utilizes the Samaritan dialect as their liturgical tongue. As a non- first language , it is studied mostly by non-Israeli Jews and students in Israel, by archaeologists and linguists specializing in the Middle East and its civilizations , and by theologians in Christian seminaries . The modern English word "Hebrew" is derived from Old French Ebrau , via Latin from
19536-421: The years since 1820 are taken as a "period of lower astronomical activity". The new, well-equipped observatory did not work as effectively as other ones; Gauss's astronomical research had the character of a one-man enterprise without a long-time observation program, and the university established a place for an assistant only after Harding died in 1834. Nevertheless, Gauss twice refused the opportunity to solve
19684-630: Was Abraham Gotthelf Kästner , whom Gauss called "the leading mathematician among poets, and the leading poet among mathematicians" because of his epigrams . Astronomy was taught by Karl Felix Seyffer , with whom Gauss stayed in correspondence after graduation; Olbers and Gauss mocked him in their correspondence. On the other hand, he thought highly of Georg Christoph Lichtenberg , his teacher of physics, and of Christian Gottlob Heyne , whose lectures in classics Gauss attended with pleasure. Fellow students of this time were Johann Friedrich Benzenberg , Farkas Bolyai , and Heinrich Wilhelm Brandes . He
19832-421: Was a spoken language , and Amoraic Hebrew (also called Late Rabbinic Hebrew or Mishnaic Hebrew II), which was a literary language . The earlier section of the Talmud is the Mishnah that was published around 200 CE, although many of the stories take place much earlier, and were written in the earlier Mishnaic dialect. The dialect is also found in certain Dead Sea Scrolls. Mishnaic Hebrew is considered to be one of
19980-585: Was a German mathematician , astronomer , geodesist , and physicist who contributed to many fields in mathematics and science. He was director of the Göttingen Observatory and professor of astronomy from 1807 until his death in 1855. He is widely considered one of the greatest mathematicians ever. While studying at the University of Göttingen , he propounded several mathematical theorems . Gauss completed his masterpieces Disquisitiones Arithmeticae and Theoria motus corporum coelestium as
20128-792: Was a member of the Lutheran church , like most of the population in northern Germany. It seems that he did not believe all dogmas or understand the Holy Bible quite literally. Sartorius mentioned Gauss's religious tolerance , and estimated his "insatiable thirst for truth" and his sense of justice as motivated by religious convictions. In his doctoral thesis from 1799, Gauss proved the fundamental theorem of algebra which states that every non-constant single-variable polynomial with complex coefficients has at least one complex root . Mathematicians including Jean le Rond d'Alembert had produced false proofs before him, and Gauss's dissertation contains
20276-457: Was carried out against the Roman Empire by the Jews of Judaea . Aramaic and, to a lesser extent, Greek were already in use as international languages, especially among societal elites and immigrants. Hebrew survived into the medieval period as the language of Jewish liturgy , rabbinic literature , intra-Jewish commerce, and Jewish poetic literature . The first dated book printed in Hebrew
20424-701: Was deeply affected by this quarrel but saw no possibility to help them. Gauss took part in academic administration: three times he was elected as dean of the Faculty of Philosophy. Being entrusted with the widow's pension fund of the university, he dealt with actuarial science and wrote a report on the strategy for stabilizing the benefits. He was appointed director of the Royal Academy of Sciences in Göttingen for nine years. Gauss remained mentally active into his old age, even while suffering from gout and general unhappiness. On 23 February 1855, he died of
20572-517: Was in keeping with the motto of his personal seal Pauca sed Matura ("Few, but Ripe"). Many colleagues encouraged him to publicize new ideas and sometimes rebuked him if he hesitated too long, in their opinion. Gauss defended himself, claiming that the initial discovery of ideas was easy, but preparing a presentable elaboration was a demanding matter for him, for either lack of time or "serenity of mind". Nevertheless, he published many short communications of urgent content in various journals, but left
20720-484: Was likely a self-taught student in mathematics since he independently rediscovered several theorems. He solved a geometrical problem that had occupied mathematicians since the Ancient Greeks , when he determined in 1796 which regular polygons can be constructed by compass and straightedge . This discovery ultimately led Gauss to choose mathematics instead of philology as a career. Gauss's mathematical diary,
20868-491: Was now a more significant written language than Aramaic within Judaea." This nationalist aspect was further emphasized during periods of conflict, as Hannah Cotton observing in her analysis of legal documents during the Jewish revolts against Rome that "Hebrew became the symbol of Jewish nationalism, of the independent Jewish State." The nationalist use of Hebrew is evidenced in several historical documents and artefacts, including
