Teleskop

Teleskop je optička sprava koja uz pomoč leći i / ili ogledala omugučava osmatranje i oslikavanje udaljenih astronomskih objekata. Riječ teleskop ima svoje porijeklo u grčkoj riječi telesko'pos što znači gledanje u daljinu.

Historija

Prvi teleskop je napravljen od strane Galileo Galileja u 1609 godini, pošto je došao na ideju da bih se novi holandski izum – dvogled mogao koristiti za osmatranje nebeskih tijela. Sam Galileo je koristio isprva riječ „perspicillum“ da bih kasnije počeo koristiti termine „telescopium“ na latinskom i „telescopio“ na talijanskom. Bosanska riječ za ovaj izum vuče svoje porijeklo iz Galileovih gore navedenih riječi. Kasnije Johannes Kepler poboljšava Galileov teleskop korištenjem duplih leći. On takođe objašnjava principe na kojima teleskop radi u svojoj knjizi „Astronomiae Pars Optica and Dioptrice“

Postolje

Johannes Kepler Montiranje teleskopa na postolje se vrši na dva osnovna načina – ekvatorijalno i azimutalno. Večina jednostavnijih teleskopa se montira ekvatorijalno zbog lakšeg kompenziranje zemljine rotacije.

Refraktori i reflektori

Postoje dvije glavne vrste teleskopa – refraktori i reflektori. U refraktorima slika nastaje refrakcijom svjetlosti na površinama leći dok kod reflektora slika nastaje odbijanjem od ogledala unutar teleskopa. Među amaterima u čestoj je upotrebi Newtonov teleskop koji je jedna vrsta reflektora.

Najpoznatiji teleskopi u svijetu danas

Johannes Kepler
- Svemirski teleskop Hubble je teleskop koji si nalazi u orbiti oko Zemlje. Plasiranjem ovog teleskopa van zemljine atmosfere izbjegnute su atmosferske smetnje koje stvaraju velike neprilike za sve teleskope koji se nalaze na površini naše planete. Hubble se primarno koriste za osmatranje nebeskih objekata u infra-crvenom i ultra-ljubičastom spektrumu.
- VLT (Very Large Telescope) ili prevedeno na bosanski Veoma Veliki Teleskop je teleskop Evropske Južne Observatorije (European Southern Observatory, ESO) i smješten je u pustinji Atacama u Čileu. Razlog za ovakvu lokaciju su izvrsne vremenske prilike u ovoj pustinji. Teleskop se sastoji od četri ogledala promjera 8 metara koja su uvezana uz pomoć računara i mogu se koristiti zajedno za osmatranje istih nebeskih objekata.
- Keck teleskopi na ugašenom vulkanu Mauna Kai na Havajima su jedni od največih teleskopa na svijetu. Prvi je počeo sa svojim radom 1993 godine a drugi 1996 godine.

Galileo Galilej

Galilei Galileo (rođen 15. februara 1564. preminuo 8. januara 1642.), talijanski matematičar, fizičar i astronom. Galilei je otac moderne astronomije. Pronašao je zakone slobodnog pada tijela, prvi uveo opitnu metodu i matematičko formuliranje fizičkih zakona i na taj način postavio temelje klasične fizike. Otkrio je cikloidu i njenu primjenu na lukove mostova. Osnovao je balistiku, određujući paraboličku putanju zrna. Konstruirao je prvi termoskop. 1610. godine je izradio poznati Galileiev durbin sa uvećanjem od 20x, na temelju već postojećeg koji je imao uvećanje od 10x, i njime otkrio planine na Mjesecu, četiri Jupiterova satelita koji nose i njegovo ime, i zvjezdanu konstrukciju Mliječne staze. Otkrio je da i planet Venera ima iste faze kao i Mjesec. U svom djelu Dialogo sopra i due massimi sistemi del mondo tolemaico e copernicano, objavljenog u Firenci 1632. godine, iznio je učenje heliocentričnog sustava i zbog toga ga je inkvizicija 1633. godine stavila u okove i odvela u Rim, kod pape Urbana VIII. Poslije dva tjedna provedena u karanteni na inzistiranje Ferninanda II. de Medicia, premješten je u rezidenciju toskanskog konzula. U aprilu 1633. godine je inkvizicija počela njegovo ispitivanje, da bi sa suđenjem počela 22. juna 1633. godine i u namještenom sudskom procesu ga osudila na odricanje od svog učenja, na što je on i pristao, bojeći se da ga ne bi zadesila ista sudbina kao i Giordana Bruna iz godine 1600., i na zatvor neodređenog trajanja što je kasnije papa Urban VIII. pretvorio u konfinaciju (kućni pritvor). Pritvoren do smrti u svojoj kući u Firenci, završio je svoje veliko djelo Discorsi e dimonstrazioni matematiche intorno a due nuove scienze attenenti alla meccanica, koje je objavljeno 1638. godine, a u kojem je objasnio zakone fizike i mehanike u novoj svjetlosti, po čemu se i smatra osnivačem klasične fizike i mehanike. Prvo izdanje njegovih svih knjiga izdano je u Firenci između 1842. i 1856. godine u 16 knjiga. 31. oktobra 1992. godine, 359 godina poslije procesa protiv Galileia, papa Ivan Pavao II. je zatražio oprost i ukinuo presudu inkvizicije protiv Galilea Galileia. U njegovu čast, svemirska sonda, napravljena za istraživanje Jupitera, i satelitski navigacioni sustav su nazvani njegovim imenom.

Latinski

Latinski je indoevropski jezik, prvobitno govoren u oblasti oko Rima, zvanoj Latium. It gained great importance as the formal language of the Roman Empire. All Romance languages, those being most notably Spanish, French, Portuguese, Italian, and Romanian, are descended from Latin, and many words based on Latin are found in other modern languages such as English. The Latin alphabet, derived from the Greek, remains the most widely-used alphabet in the world. It is said that 80 percent of scholarly English words are derived from Latin (in a large number of cases by way of French). Moreover, in the Western world, Latin was a lingua franca, the learned language for scientific and political affairs, for more than a thousand years, being eventually replaced by French in the 18th century and English in the late 19th. Ecclesiastical Latin remains the formal language of the Roman Catholic Church to this day, and thus the official national language of the Vatican. The Church used Latin as its primary liturgical language until the Second Vatican Council in the 1960s. Latin is also still used (drawing heavily on Greek roots) to furnish the names used in the scientific classification of living things. The modern study of Latin, along with Greek, is known as Classics.

Main features

Latin is a synthetic inflectional language: affixes (which usually encode more than one grammatical category) are attached to fixed stems to express gender, number, and case in adjectives, nouns, and pronouns, which is called declension; and person, number, tense, voice, mood, and aspect in verbs, which is called conjugation. There are five declensions (declinationes) of nouns and four conjugations of verbs. There are six noun cases: #nominative (used as the subject of the verb or the predicate nominative), #genitive (used to indicate relation or possession, often represented by the English of or the addition of s to a noun), #dative (used of the indirect object of the verb, often represented by the English to or for), #accusative (used of the direct object of the verb, or object of the preposition in some cases), #ablative (separation, source, cause, or instrument, often represented by the English by, with, from), #vocative (used of the person or thing being addressed). In addition, some nouns have a locative case used to express location (otherwise expressed by the ablative with a preposition such as in), but this survival from Proto-Indo-European is found only in the names of lakes, cities, towns, small islands, and a few other words related to locations, such as "house", "ground", and "countryside". Latin itself, being a very old language, is far closer to Proto-Indo-European than are most modern Western European languages; it has, in fact, about the same relationship with PIE as modern Italian or French has to Latin. There are six general tenses in Latin (technically they are tense/aspect/mood complexes). The indicative mood can be used with all of them. The subjunctive mood, however, has only present, imperfect, perfect, and pluperfect tenses. These tenses in the subjunctive mood do not completely correlate in meaning to the tenses in the indicative.

Present system tenses

# present (
laudo, "I praise") # imperfect (laudabam, "I was praising") # future (laudabo, "I shall praise," "I will praise")

Past system tenses

# perfect (
laudavi, "I praised", "I have praised") # pluperfect (laudaveram, "I had praised") # future perfect (laudavero, "I shall have praised," "I will have praised") The future perfect tense can also imply a normal future idea (like in "When I will have run...") and so may also sometimes be included in the present system.

Latin and Romance

After the collapse of the Roman Empire, Latin evolved into the various Romance languages. These were for many centuries only spoken languages, Latin still being used for writing. For example, Latin was the official language of Portugal until 1296 when it was replaced by Portuguese. The Romance languages evolved from Vulgar Latin, the spoken language of common usage, which in turn evolved from an older speech which also produced the formal classical standard. Latin and Romance differ (for example) in that Romance had distinctive stress, whereas Latin had distinctive length of vowels. In Italian and Sardo logudorese, there is distinctive length of consonants and stress, in Spanish only distinctive stress, and in French even stress is no longer distinctive. Another major distinction between Romance and Latin is that all Romance languages, excluding Romanian, have lost their case endings in most words except for some pronouns. Romanian retains a direct case (nominative/accusative), an indirect case (dative/genitive), and vocative. In Italy, Latin is still compulsory in secondary schools as
Liceo Classico and Liceo Scientifico which are usually attended by people who aim to the highest level of education. In Liceo Classico Ancient Greek is a compulsory subject.

Latin and English

See Latin influence in English for a more complete exposition. English grammar is independent of Latin grammar, though prescriptive grammarians in English have been heavily influenced by Latin. Attempts to make English grammar follow Latin rules — such as the prohibition against the split infinitive — have not worked successfully in regular usage. However, as many as half the words in English were derived from Latin, including many words of Greek origin first adopted by the Romans, not to mention the thousands of French, hundreds of Spanish, Portuguese and Italian words of Latin origin that have also enriched English. During the 16th and on through the 18th century English writers created huge numbers of new words from Latin and Greek roots. These words were dubbed "inkhorn" or "inkpot" words (as if they had spilled from a pot of ink). Many of these words were used once by the author and then forgotten, but some remain. Imbibe, extrapolate, dormant and inebriation are all inkhorn terms carved from Latin words. In fact, the word etymology is derived from the Greek word etymologia, meaning "true sense of the word." Latin was once taught in many of the schools in Britain with academic leanings - perhaps 25% of the total [http://www.channel4.com/history/microsites/T/teachem2/thennow/]. However, the requirement for it was gradually abandoned in the professions such as the law and medicine, and then, from around the late 1960s, for admission to university. After the introduction of the Modern Language GCSE in the 1980s, it was gradually replaced by other languages, although it is now being taught by more schools along with other classical languages.

Latin education

The linguistic element of Latin courses offered in high schools or secondary schools, and in universities, is primarily geared toward an ability to translate Latin texts into modern languages, rather than using it in oral communication. As such, the skill of reading is heavily emphasized, whereas speaking and listening skills are barely touched upon. However, there is a growing movement, sometimes known as the Living Latin movement, whose supporters believe that Latin can, or should, be taught in the same way that modern "living" languages are taught, that is, as a means of both spoken and written communication. One of the most interesting aspects of such an approach is that it assists speculative insight into how many of the ancient authors spoke and incorporated sounds of the language stylistically; without understanding how the language is meant to be heard it is very difficult to identify patterns in Latin poetry. Institutions offering Living Latin instruction include the Vatican and the University of Kentucky. In Britain the Classical Association encourages this approach, and there has been something of a vogue for books describing the adventures of a mouse called Minimus. In the United States there is a thriving competitive organization for high school Latin students, the National Junior Classical League (the second-largest youth organization in the world after the Boy Scouts), backed up by the Senior Classical League for college students. Many would-be international auxiliary languages have been heavily influenced by Latin, and the moderately successful Interlingua considers itself to be the modernized and simplified version of the language (
le latino moderne international e simplificate). Latin translations of modern literature such as Paddington Bear, Winnie the Pooh, Harry Potter and the Philosopher's Stone, Le Petit Prince, Max und Moritz, and The Cat in the Hat have also helped boost interest in the language.
