Mendeleyev (masculine) or Mendeleyeva (feminine or masculine genitive) may also refer to: Dmitri Mendeleev Dmitri Ivanovich Mendeleev ForMemRS (sometimes romanized as Mendeleyev , Mendeleiev , or Mendeleef ; English: / ˌ m ɛ n d əl ˈ eɪ ə f / MEN -dəl- AY -əf ; Russian: Дмитрий Иванович Менделеев , romanized: Dmitriy Ivanovich Mendeleyev , IPA: [ˈdmʲitrʲɪj ɪˈvanəvʲɪtɕ mʲɪnʲdʲɪˈlʲejɪf] ; 8 February [ O.S. 27 January] 1834 – 2 February [O.S. 20 January] 1907)
178-572: A vocational school until they have full job qualifications. It is also possible to get an erweiterter Realschulabschluss after 10th grade that allows the students to continue their education at the Oberstufe of a gymnasium and get an Abitur . There are two types of vocational school in Germany: the Berufsschule , a part-time vocational school and a part of Germany's dual education system , and
267-769: A British or American comprehensive school . However, it offers the same school-leaving certificates as the other three types—the Hauptschulabschluss (school-leaving certificate of a Hauptschule after 9th grade or in Berlin and North Rhine-Westphalia after 10th grade), the Realschulabschluss (also called Mittlere Reife , school-leaving certificate of a Realschule after 10th Grade) and Abitur (also called Hochschulreife , school-leaving certificate after 12th Grade). Students who graduate from Hauptschule or Realschule may continue their schooling at

In Sweden , there are two different kinds of branches of studies: the first branch focuses on giving a vocational education while the second branch focuses on giving preparation for higher education. While students from both branches can go on to study at a university, students of the vocational branch graduate with a degree within their attended program. There are 18 national programs, 12 vocational and 6 preparatory. In
445-444: A Swiss university. The gymnasia are operated by the cantons of Switzerland , and accordingly in many cantons they are called Kantonsschule (cantonal school). In Bosnia and Herzegovina , Croatia , Montenegro , North Macedonia , Serbia , and Slovenia , a gymnasium education takes four years following a compulsory eight or nine-year elementary education and ending with a final aptitude test called Matura . In these countries,
534-473: A certain type of gymnasia called Classical Gymnasia ( klasična gimnazija ). In all of the countries, the gymnasium ( gimnazija / gjimnazi ) is generally viewed as a destination for best-performing students and as the type of school that serves primarily to prepare students for university studies, while other students go to technical/vocational schools. Therefore, gymnasia often base their admittance criteria on an entrance exam, elementary school grades, or
623-603: A combination of the two. Depending on country, the final degree (if any) is called Abitur , Artium , Diploma , Matura , Maturita or Student and it usually opens the way to professional schools directly. However, these degrees are occasionally not fully accredited internationally, so students wanting to attend a foreign university often have to submit to further exams to be permitted access to them. In countries like Austria, most university faculties accept only students from secondary schools that last four years (rather than three). This includes all Gymnasium students but only
712-537: A common foundation course can choose between different fields of study that meet the individual student's abilities and interests. The course is offered in Aasiaat , Nuuk , Sisimiut and Qaqortoq , with one in Ilulissat to be opened in 2015, latest in 2016 if approved by Inatsisartut . In Finland, the admissions to gymnasia are competitive, the accepted people comprising 51% of the age group. The gymnasia concludes with

He worked on
890-457: A member of the Nobel Committee for Chemistry, had a great deal of influence in the academy and also pressed for the rejection of Mendeleev, arguing that the periodic system was too old to acknowledge its discovery in 1906. According to the contemporaries, Arrhenius was motivated by the grudge he held against Mendeleev for his critique of Arrhenius's dissociation theory . After heated arguments,
979-401: A new element being discovered at a rate of approximately one per year. Other scientists had previously identified periodicity of elements. John Newlands described a Law of Octaves , noting their periodicity according to relative atomic weight in 1864, publishing it in 1865. His proposal identified the potential for new elements such as germanium . The concept was criticized, and his innovation

In-state schools, a student who is not baptized into either the Catholic or Protestant faiths is allowed to choose which of these classes to take. The only exception to this
1157-419: A part of vocational high schools, in effect making Gymnasium the preferred choice for all pupils aiming for university diplomas. In Germany, other types of secondary school are called Realschule , Hauptschule and Gesamtschule . These are attended by about two thirds of the students and the first two are practically unknown in other parts of the world. A Gesamtschule largely corresponds to
1246-680: A professor at the Saint Petersburg Technological Institute and Saint Petersburg State University in 1864, and 1865, respectively. In 1865, he became a Doctor of Science for his dissertation "On the Combinations of Water with Alcohol". He achieved tenure in 1867 at St. Petersburg University and started to teach inorganic chemistry while succeeding Voskresenskii to this post; by 1871, he had transformed Saint Petersburg into an internationally recognized center for chemistry research. In 1863, there were 56 known elements with

He noted that tellurium has a higher atomic weight than iodine , but he placed them in the right order, incorrectly predicting that the accepted atomic weights at the time were at fault. He was puzzled about where to put the known lanthanides , and predicted the existence of another row to
1424-714: A remark that burning petroleum as a fuel "would be akin to firing up a kitchen stove with bank notes". In 1905, Mendeleev was elected a member of the Royal Swedish Academy of Sciences . The following year the Nobel Committee for Chemistry recommended to the Swedish Academy to award the Nobel Prize in Chemistry for 1906 to Mendeleev for his discovery of the periodic system. He was also elected an International Member of
1513-608: A specific focus. (This also differs from country to country.) The four traditional branches are: Curricula differ from school to school but generally include literature, mathematics, informatics , physics, chemistry, biology, geography, art (as well as crafts and design), music, history, philosophy, civics /citizenship, social sciences, and several foreign languages. Schools concentrate not only on academic subjects, but also on producing well-rounded individuals, so physical education and religion or ethics are compulsory, even in non-denominational schools which are prevalent. For example,
1602-623: A substance as the temperature at which cohesion and heat of vaporization become equal to zero and the liquid changes to vapor, irrespective of the pressure and volume. Mendeleev is given credit for the introduction of the metric system to the Russian Empire . He invented pyrocollodion , a kind of smokeless powder based on nitrocellulose . This work had been commissioned by the Russian Navy , which however did not adopt its use. In 1892 Mendeleev organized its manufacture. Mendeleev studied
1691-488: A very technical and highly demanding course, being available as final exams. Usually, schools will have all classes mandatory in switching combinations for the first three or so years (with the exception of Technasium which is a free choice from the second year onward), after which students will choose their subjects in the directions of Economics and Society, Culture and Society, Nature and Health, Nature and Technology or Technology. The equivalent without classical languages
1780-715: A wealthy merchant. In 1889, a local librarian published an article in the Tobolsk newspaper where he claimed that Yakov was a baptized Teleut , an ethnic minority known as "white Kalmyks " at the time. Since no sources were provided and no documented facts of Yakov's life were ever revealed, biographers generally dismiss it as a myth. In 1908, shortly after Mendeleev's death, one of his nieces published Family Chronicles. Memories about D. I. Mendeleev where she voiced "a family legend" about Maria's grandfather who married "a Kyrgyz or Tatar beauty whom he loved so much that when she died, he also died from grief". This, however, contradicts

Compared to the somewhat equivalent A-levels in the UK, Danish gymnasia have more mandatory subjects. The subjects are divided into levels, where A-levels usually run through all three years, B-levels usually two years and C-levels one year (apart from PE which exists as

All are government-funded. See Voorbereidend wetenschappelijk onderwijs (in English) for the full article on Dutch "preparatory scientific education". In Denmark , Estonia , the Faroe Islands , Finland , Greenland , Iceland , Latvia , Norway and Sweden , gymnasium consists of three years, usually starting at
2225-488: Is generally viewed as a destination for the best-performing students and as the type of school that serves primarily to prepare students for university. In the Czech Republic and Slovakia , gymnázium (also spelled gymnasium ) is a type of school that provides secondary education. Secondary schools, including gymnázium , lead to the maturita exam. There are different types of gymnázium distinguished by
2314-586: Is in most cases free (and in other cases at low cost). It consists of six years, after eight years (including kindergarten ) of primary school, in which pupils study the same subjects as their German counterparts, with the addition of compulsory Ancient Greek , Latin and Klassieke Culturele Vorming (Classical Cultural Education), history of the Ancient Greek and Roman culture and literature. Schools have some freedom in choosing their specific curriculum, with for example Spanish, Philosophy and Technasium ,
2403-536: Is in the state of Berlin , where the subject ethics is mandatory for all students and (Christian) religious studies can only be chosen additionally. A similar situation is found in Brandenburg where the subject life skills, ethics, and religious education ( Lebensgestaltung, Ethik, Religionskunde, LER ) is the primary subject but parents/guardians or students older than 13 can choose to replace it with (Christian) religious studies or take both. The intention behind LER
2492-568: Is only two years, instead of the three required for STX, HHX, and HTX. All different types of gymnasia (except for HF) theoretically gives the same eligibility for university. However, because of the different subjects offered, students may be better qualified in an area of further study. E.g. HHX students have subjects that make them more eligible for studies such as business studies or economics at university, while HTX offer applied science and mathematics that benefit studies in Science or Engineering. There

The subjects taught are mathematics, Albanian language, one to three foreign languages, history, geography, computer science, the natural sciences (biology, chemistry, physics), history of art, music, philosophy, logic, physical education, and
2670-476: Is that students should get an objective insight on questions of personal development and ethics as well as on the major world religions. For younger students nearly the entire curriculum of a gymnasium is compulsory; in higher years additional subjects are available and some of the hitherto compulsory subjects can be dropped, but the choice is not as wide as in other school systems, such as US high schools. Although some specialist gymnasia have English or French as
2759-699: Is true that Mendeleev in 1892 became head of the Archive of Weights and Measures in Saint Petersburg, and evolved it into a government bureau the following year, but that institution was charged with standardising Russian trade weights and measuring instruments, not setting any production quality standards. Also, Mendeleev's 1865 doctoral dissertation was entitled "A Discourse on the combination of alcohol and water", but it only discussed medical-strength alcohol concentrations over 70%, and he never wrote anything about vodka. A number of places and objects are associated with

2848-532: The Abitur examinations, which complete the Gymnasium education, after 13 years of primary school and Gymnasium combined. In addition, some states offer a 12-year curriculum leading to the Abitur . These final examinations are now centrally drafted and controlled ( Zentralabitur ) in all German states except for Rhineland-Palatinate and provide a qualification to attend any German university. In Italy originally
2937-599: The Berufsfachschule , a full-time vocational school outside the dual education system. Students who graduate from a vocational school and students who graduate with a good grade point average from a Realschule can continue their schooling at another type of German secondary school, the Fachoberschule , a vocational high school. The school leaving exam of this type of school, the Fachhochschulreife , enables
3026-830: The ginnasio indicated a type of five-year junior high school (age 11 to 16) and preparing to the three year Classical Lyceum (age 16 to 19), a high school focusing on classical studies and humanities . After the school reform that unified the junior high school system, the term ginnasio stayed to indicate the first two year of Liceo Classico , now five years long. An Italian high school student who enrolls in Liceo Classico follows this study path: Quarta Ginnasio (gymnasium fourth year, age 14), Quinta Ginnasio (gymnasium fifth year, age 15), Prima Liceo (lyceum first year, age 16), Seconda Liceo (lyceum second year, age 17) and Terza Liceo (lyceum third year, age 18). Some believe this still has some sense, since
3115-490: The American Philosophical Society . The Chemistry Section of the Swedish Academy supported this recommendation. The academy was then supposed to approve the committee's choice, as it has done in almost every case. Unexpectedly, at the full meeting of the academy, a dissenting member of the Nobel Committee, Peter Klason , proposed the candidacy of Henri Moissan whom he favored. Svante Arrhenius , although not

He was especially active in improving the Russian petroleum industry, making detailed comparisons with the more advanced industry in Pennsylvania . Although not well-grounded in economics, he had observed industry throughout his European travels, and in 1891 he helped convince the Ministry of Finance to impose temporary tariffs with
3293-462: The Faroe Islands , there are also four kinds of gymnasia, which are the equivalents of the Danish programmes: Studentaskúli (equivalent to STX), Handilsskúli (HHX), Tekniski skúli (HTX) and HF (HF). Studentaskúli and HF are usually located at the same institutions as can be seen in the name of the institute in Eysturoy : Studentaskúlin og HF-skeiðið í Eysturoy. In Greenland , there
3382-476: The Protestant Reformation in the 16th century. The term was derived from the classical Greek word γυμνάσιον ( gymnasion ), which was originally applied to an exercising ground in ancient Athens . Here teachers gathered and gave instruction between the hours devoted to physical exercises and sports, and thus the term became associated with and came to mean an institution of learning. This use of

In Switzerland, gymnasia ( Gymnasien , gymnases ) are selective schools that provide a three- to six-year (depending on the canton) course of advanced secondary education intended to prepare students to attend university. They conclude with a nationally standardized exam, the maturité or Maturität , often shortened to " Matura or Matur ", which if passed allows students to attend

Mendeleev was the youngest of 17 siblings, of whom "only 14 stayed alive to be baptized" according to Mendeleev's brother Pavel, meaning the others died soon after their birth. The exact number of Mendeleev's siblings differs among sources and is still a matter of some historical dispute. Unfortunately for the family's financial well-being, his father became blind and lost his teaching position. His mother
3827-478: The German constitution guarantees the separation of church and state, so although religion or ethics classes are compulsory, students may choose to study a specific religion or none at all. Today, a number of other areas of specialization exist, such as gymnasia specializing in economics, technology or domestic sciences. In some countries, there is a notion of progymnasium , which is equivalent to beginning classes of
3916-690: The Sanskrit grammarians of ancient India, who had created theories of language based on their discovery of the two-dimensional patterns of speech sounds (exemplified by the Śivasūtras in Pāṇini 's Sanskrit grammar ). Mendeleev was a friend and colleague of the Sanskritist Otto von Böhtlingk , who was preparing the second edition of his book on Pāṇini at about this time, and Mendeleev wished to honor Pāṇini with his nomenclature. The original draft made by Mendeleev would be found years later and published under
4005-442: The aim of fostering Russian infant industries . In 1890 he resigned his professorship at St. Petersburg University following a dispute with officials at the Ministry of Education over the treatment of university students. In 1892 he was appointed director of Russia's Central Bureau of Weights and Measures, and led the way to standardize fundamental prototypes and measurement procedures. He set up an inspection system, and introduced
4094-421: The definitive textbook of its time. It was published in two volumes between 1868 and 1870, and Mendeleev wrote it as he was preparing a textbook for his course. This is when he made his most important discovery. As he attempted to classify the elements according to their chemical properties, he noticed patterns that led him to postulate his periodic table; he claimed to have envisioned the complete arrangement of
4183-1108: The degree awarded substituted for the bachelor's degree (Baccalaureate) previously awarded by a college or university so that universities in Germany became exclusively graduate schools. In the United States, the German Gymnasium curriculum was used at a number of prestigious universities, such as the University of Michigan, as a model for their undergraduate college programs. Pupils study subjects such as German, mathematics, physics, chemistry, geography, biology, arts, music, physical education, religion, history and civics /citizenship/ social sciences and computer science . They are also required to study at least two foreign languages. The usual combinations are English and French or English and Latin , although many schools make it possible to combine English with another language, most often Spanish, Ancient Greek , or Russian. Religious education classes are
4272-413: The determination of the nature of such indefinite compounds as solutions . In another department of physical chemistry , he investigated the expansion of liquids with heat, and devised a formula similar to Gay-Lussac's law of the uniformity of the expansion of gases, while in 1861 he anticipated Thomas Andrews ' conception of the critical temperature of gases by defining the absolute boiling-point of
4361-601: The divorce, Mendeleev was technically a bigamist ; the Russian Orthodox Church required at least seven years before lawful remarriage. His divorce and the surrounding controversy contributed to his failure to be admitted to the Russian Academy of Sciences (despite his international fame by that time). His daughter from his second marriage, Lyubov, became the wife of the famous Russian poet Alexander Blok . His other children were son Vladimir (a sailor, he took part in
4450-478: The documented family chronicles, and neither of those legends is supported by Mendeleev's autobiography, his daughter's or his wife's memoirs. Yet some Western scholars still refer to Mendeleev's supposed "Mongol", "Tatar", " Tartarian " or simply "Asian" ancestry as a fact. Mendeleev was raised as an Orthodox Christian , his mother encouraging him to "patiently search divine and scientific truth". His son Ivan would later inform that Mendeleev had departed from

Awakening, I immediately wrote it down on a piece of paper, only in one place did a correction later seem necessary. Unaware of the earlier work on periodic tables going on in the 1860s, he made the following table: By adding additional elements following this pattern, Mendeleev developed his extended version of

#17328878150474628-649: The father's alma mater. The now poor Mendeleev family relocated to Saint Petersburg, where he entered the Main Pedagogical Institute in 1850. After graduation, he contracted tuberculosis , causing him to move to the Crimean Peninsula on the northern coast of the Black Sea in 1855. While there, he became a science master of the 1st Simferopol Gymnasium . In 1857, he returned to Saint Petersburg with fully restored health. Between 1859 and 1861, he worked on
4717-429: The final test is standardized at the state level and can serve as an entrance qualification for universities. There are either public (state-run and tuition-free), religious (church-run with secular curriculum and tuition-free) or private (fee-paying) gymnasium schools in these countries. The subjects taught are mathematics, the native language, one to three foreign languages, history, geography, informatics (computers),

The last two years of the gymnasium kept the previous denomination and the related scholastic curriculum for the following decades. In the Netherlands, gymnasium is the highest variant of secondary education, offering the academically most promising youngsters (top 5%) a quality education that
4895-402: The former meaning of a place for physical education was retained. Because gymnasia prepare students for university study, they are thus meant for the more academically minded students, who are sifted out between the ages of 10 and 13. In addition to the usual curriculum, students of a gymnasium often study Latin and Ancient Greek . Some gymnasia provide general education, while others have
4984-412: The full gymnasium, with the rights to continue education in a gymnasium . Here, the prefix pro - is equivalent to pre -, indicating that this curriculum precedes normal gymnasium studies. In Central European, Nordic , Benelux and Baltic countries, this meaning for "gymnasium" (that is a secondary school preparing the student for higher education at a university) has been the same at least since

In fact, the 40% standard was already introduced by the Russian government in 1843, when Mendeleev was nine years old. It
5251-729: The language of instruction, at most gymnasia lessons (apart from foreign language courses) are conducted in Standard German . The number of years of instruction at a gymnasium differs between the states. It varies between six and seven years in Berlin and Brandenburg (primary school is six years in both as opposed to four years in the rest of Germany) and eight in Bavaria , Hesse and Baden-Württemberg among others. While in Saxony and Thuringia students have never been taught more than eight years in Gymnasium (by default), nearly all states now conduct
5340-605: The length of study. In the Czech Republic there are eight-year, six-year, and four-year types, and in Slovakia there are eight-year and four-year types, of which the latter is more common. In both countries, there are also bilingual (Czech or Slovak with English, French, Spanish, Italian, German, or Russian; in Slovakia, bilingual gymnáziums are five-year) and private gymnáziums . German gymnasia are selective schools. They offer
5429-660: The majority of the academy chose Moissan by a margin of one vote. The attempts to nominate Mendeleev in 1907 were again frustrated by the absolute opposition of Arrhenius. In 1907, Mendeleev died at the age of 72 in Saint Petersburg from influenza , just 6 days short of his 73rd birthday. His last words were to his physician: "Doctor, you have science, I have faith," which is possibly a Jules Verne quote. Mendeleev made other important contributions to science. The Russian chemist and science historian Lev Chugaev characterized him as "a chemist of genius, first-class physicist,

He bemoaned the widespread acceptance of spiritualism in Russian culture, and its negative effects on the study of science. A very popular Russian story credits Mendeleev with setting the 40% standard strength of vodka . For example, Russian Standard vodka advertises: "In 1894, Dmitri Mendeleev,

Gymnasia may expel students who academically under-perform their classmates or behave in a way that is often seen as undesirable and unacceptable. Historically, the German Gymnasium also included in its overall accelerated curriculum post-secondary education at college level and

In 1876, he became obsessed with Anna Ivanova Popova and began courting her; in 1881 he proposed to her and threatened suicide if she refused. His divorce from Leshcheva was finalized one month after he had married Popova (on 2 April) in early 1882. Even after
5785-489: The name and achievements of the scientist. In Saint Petersburg his name was given to D. I.

Next to it there is a monument to him that consists of his sitting statue and a depiction of his periodic table on the wall of the establishment. In
5874-471: The name of gymnasium. By the 20th century, this practice was followed in almost the entire Austrian-Hungarian , German , and Russian Empires . In the modern era, many countries which have gymnasia were once part of these three empires. In Albania, a gymnasium ( Albanian : Gjimnaz ) education takes three years following a compulsory nine-year elementary education and ending with a final aptitude test called Albanian : Matura Shtetërore . The final test

Though Mendeleev was widely honored by scientific organizations all over Europe, including (in 1882) the Davy Medal from the Royal Society of London (which later also awarded him the Copley Medal in 1905), he resigned from Saint Petersburg University on 17 August 1890. He

He wrote: "The capital fact to note is that petroleum was born in the depths of the earth, and it is only there that we must seek its origin." Beginning in the 1870s, he published widely beyond chemistry, looking at aspects of Russian industry, and technical issues in agricultural productivity. He explored demographic issues, sponsored studies of

On 6 March 1869, he made a formal presentation to the Russian Chemical Society, titled The Dependence between the Properties of the Atomic Weights of the Elements , which described elements according to both atomic weight (now called relative atomic mass ) and valence . This presentation stated that Mendeleev published his periodic table of all known elements and predicted several new elements to complete
6319-492: The sciences. In the last few decades, more autonomy has been granted to schools, and various types have been developed, focusing on sports, music, or economics, for example. In Belarus, gymnasium is the highest variant of secondary education, which provides advanced knowledge in various subjects. The number of years of instruction at a gymnasium is 11. However, it is possible to cover all required credits in 11 years, by taking additional subjects each semester. In Belarus, gymnasium
6408-428: The social sciences (sociology, ethics, psychology, politics and economy). The gymnasium is generally viewed as a destination for the best-performing students and as the type of school that serves primarily to prepare students for university, while other students go to technical/vocational schools. Therefore, gymnasia often base their admittance criteria on an entrance exam, elementary school grades, or some combination of
6497-430: The table in a Russian-language journal. Only a few months after, Meyer published a virtually identical table in a German-language journal. Mendeleev has the distinction of accurately predicting the properties of what he called ekasilicon, ekaaluminium and ekaboron ( germanium , gallium and scandium , respectively). Mendeleev also proposed changes in the properties of some known elements. Prior to his work, uranium
6586-428: The table which were the actinides which were some of the heaviest in atomic weight. Some people dismissed Mendeleev for predicting that there would be more elements, but he was proven to be correct when Ga ( gallium ) and Ge ( germanium ) were found in 1875 and 1886 respectively, fitting perfectly into the two missing spaces. By using Sanskrit prefixes to name "missing" elements, Mendeleev may have recorded his debt to
6675-560: The term did not prevail among the Romans , but was revived during the Renaissance in Italy , and from there passed into the Netherlands and Germany during the 15th century. In 1538, Johannes Sturm founded at Strasbourg the school which became the model of the modern German gymnasium. In 1812, a Prussian regulation ordered all schools with the right to send their students to the university to bear
6764-477: The theory and practice of protectionist trade and on agriculture. In an attempt at a chemical conception of the aether , he put forward a hypothesis that there existed two inert chemical elements of lesser atomic weight than hydrogen . Of these two proposed elements, he thought the lighter to be an all-penetrating, all-pervasive gas, and the slightly heavier one to be a proposed element, coronium . Mendeleev devoted much study and made important contributions to
6853-408: The tradition of priests of that time, Pavel's children were given new family names while attending the theological seminary , with Ivan getting the family name Mendeleev after the name of a local landlord. Maria Kornilieva came from a well-known family of Tobolsk merchants, founders of the first Siberian printing house who traced their ancestry to Yakov Korniliev, a 17th-century posad man turned
6942-480: The two-year ginnasio has a differently oriented curriculum from the Liceo . Ginnasio students spend the majority of their schooling studying Greek and Latin grammar, laying the bases for the "higher" and more in depth set of studies of the Liceo , such as Greek and Latin literature and philosophy. In July 1940 the fascist Minister of National Education Giuseppe Bottai got a bill of law approved that abolished
7031-550: The two. In Austria the Gymnasium has two stages, from the age of 11 to 14, and from 15 to 18, concluding with Matura . Historically, three types existed. The Humanistisches Gymnasium focuses on Ancient Greek and Latin . The Neusprachliches Gymnasium puts its focus on actively spoken languages. The usual combination is English, French, and Latin; sometimes French can be swapped with another foreign language (like Italian, Spanish or Russian). The Realgymnasium emphasizes
7120-598: The word; pl. gymnasia ) is a term in various European languages for a secondary school that prepares students for higher education at a university . It is comparable to the US English term preparatory high school or the British term grammar school . Before the 20th century, the gymnasium system was a widespread feature of educational systems throughout many European countries. The word γυμνάσιον ( gumnásion ), from Greek γυμνός ( gumnós ) 'naked' or 'nude',
7209-712: The year the students turn 16 years old after nine or ten years of primary school. In Lithuania , the gymnasium usually consists of four years of schooling starting at the age of 15–16, the last year roughly corresponding to the first year of college . Most gymnasia in the Nordic countries are free. Universal student grants are also available in certain countries for students over 18. In Denmark (see also Gymnasium (Denmark) ), there are four kinds of gymnasia: STX (Regular Examination Programme), HHX (Higher Business Examination Programme), HTX (Higher Technical Examination Programme) and HF (Higher Preparatory Examination Programme). HF
7298-545: Was a Russian chemist and inventor. He is best known for formulating the Periodic Law and creating a version of the periodic table of elements . He used the Periodic Law not only to correct the then-accepted properties of some known elements, such as the valence and atomic weight of uranium , but also to predict the properties of three elements that were yet to be discovered ( germanium , gallium and scandium ). Mendeleev
7387-558: Was born in the village of Verkhnie Aremzyani, near Tobolsk in Siberia , to Ivan Pavlovich Mendeleev (1783–1847) and Maria Dmitrievna Mendeleeva ( née Kornilieva) (1793–1850). Ivan worked as a school principal and a teacher of fine arts, politics and philosophy at the Tambov and Saratov gymnasiums. Ivan's father, Pavel Maximovich Sokolov, was a Russian Orthodox priest from the Tver region. As per
7476-450: Was described in 2015. A large lunar impact crater Mendeleev , that is located on the far side of the Moon, also bears the name of the scientist. The Russian Academy of Sciences has occasionally awarded a Mendeleev Golden Medal since 1965. On 8 February 2016, Google celebrated Dmitri Mendeleev's 182nd Birthday with a doodle. Gymnasium (school) Gymnasium (and variations of
7565-563: Was elected a Foreign Member of the Royal Society (ForMemRS) in 1892 , and in 1893 he was appointed director of the Bureau of Weights and Measures, a post which he occupied until his death. Mendeleev also investigated the composition of petroleum , and helped to found the first oil refinery in Russia. He recognized the importance of petroleum as a feedstock for petrochemicals . He is credited with
7654-580: Was first used in Ancient Greece , in the sense of a place for both physical and intellectual education of young men. The latter meaning of a place of intellectual education persisted in many European languages (including Albanian , Bulgarian , Czech , Dutch , Estonian , Greek , German , Hungarian , Macedonian , Polish , Russian , Scandinavian languages , Croatian , Serbian , Slovak , Slovenian and Ukrainian ), whereas in other languages, like English ( gymnasium , gym ) and Spanish ( gimnasio ),
7743-633: Was forced to work and she restarted her family's abandoned glass factory. At the age of 13, after the passing of his father and the destruction of his mother's factory by fire, Mendeleev attended the Gymnasium in Tobolsk. In 1849, his mother took Mendeleev across Russia from Siberia to Moscow with the aim of getting Mendeleev enrolled at the Moscow University . The university in Moscow did not accept him. The mother and son continued to Saint Petersburg to
7832-455: Was not recognized by the Society of Chemists until 1887. Another person to propose a periodic table was Lothar Meyer , who published a paper in 1864 describing 28 elements classified by their valence, but with no predictions of new elements. After becoming a teacher in 1867, Mendeleev wrote Principles of Chemistry ( Russian : Основы химии , romanized : Osnovy khimii ), which became
7921-445: Was supposed to have valence 3 and atomic weight about 120. Mendeleev realized that these values did not fit in his periodic table, and doubled both to valence 6 and atomic weight 240 (close to the modern value of 238). For his predicted three elements, he used the prefixes of eka, dvi, and tri ( Sanskrit one, two, three) in their naming. Mendeleev questioned some of the currently accepted atomic weights (they could be measured only with
