62-674: Nomenclature of Organic Chemistry , commonly referred to by chemists as the Blue Book , is a collection of recommendations on organic chemical nomenclature published at irregular intervals by the International Union of Pure and Applied Chemistry (IUPAC). A full edition was published in 1979, an abridged and updated version of which was published in 1993 as A Guide to IUPAC Nomenclature of Organic Compounds . Both of these are now out-of-print in their paper versions, but are available free of charge in electronic versions. After

124-817: A M.S. as professors too (and rarely, some big universities who need part-time or temporary instructors, or temporary staff), but when the positions are scarce and the applicants are many, they might prefer Ph.D. holders instead. Skills that a chemist may need on the job include: Most chemists begin their lives in research laboratories . Many chemists continue working at universities. Other chemists may start companies, teach at high schools or colleges, take samples outside (as environmental chemists ), or work in medical examiner offices or police departments (as forensic chemists ). Some software that chemists may find themselves using include: Increasingly, chemists may also find themselves using artificial intelligence , such as for drug discovery . Chemistry typically

186-403: A Master of Science (M.S.) in chemistry or in a very related discipline may find chemist roles that allow them to enjoy more independence, leadership and responsibility earlier in their careers with less years of experience than those with a bachelor's degree as highest degree. Sometimes, M.S. chemists receive more complex tasks duties in comparison with the roles and positions found by chemists with

248-559: A Ph.D. more often than not. Chemists with a Ph.D. as the highest academic degree are found typically on the research-and-development department of an enterprise and can also hold university positions as professors. Professors for research universities or for big universities usually have a Ph.D., and some research-oriented institutions might require post-doctoral training. Some smaller colleges (including some smaller four-year colleges or smaller non-research universities for undergraduates) as well as community colleges usually hire chemists with

310-604: A bachelor's degree are most commonly involved in positions related to either research assistance (working under the guidance of senior chemists in a research-oriented activity), or, alternatively, they may work on distinct (chemistry-related) aspects of a business, organization or enterprise including aspects that involve quality control, quality assurance, manufacturing, production, formulation, inspection, method validation, visitation for troubleshooting of chemistry-related instruments, regulatory affairs , "on-demand" technical services, chemical analysis for non-research purposes (e.g., as

372-466: A bachelor's degree as their highest academic degree and with the same or close-to-same years of job experience. There are positions that are open only to those that at least have a degree related to chemistry at the master's level. Although good chemists without a Ph.D. degree but with relatively many years of experience may be allowed some applied research positions, the general rule is that Ph.D. chemists are preferred for research positions and are typically

434-435: A combination of education, experience and personal achievements), the higher the responsibility given to that chemist and the more complicated the task might be. Chemistry, as a field, have so many applications that different tasks and objectives can be given to workers or scientists with these different levels of education or experience. The specific title of each job varies from position to position, depending on factors such as

Such technicians commonly do such work as simpler, routine analyses for quality control or in clinical laboratories , having an associate degree . A chemical technologist has more education or experience than a chemical technician but less than a chemist, often having a bachelor's degree in

558-409: A different field of science with also an associate degree in chemistry (or many credits related to chemistry) or having the same education as a chemical technician but more experience. There are also degrees specific to become a chemical technologist, which are somewhat distinct from those required when a student is interested in becoming a professional chemist. A Chemical technologist is more involved in

620-560: A fundamentally different language. There is no real consensus on the exact boundary where Late Latin ends and Medieval Latin begins. Some scholarly surveys begin with the rise of early Ecclesiastical Latin in the middle of the 4th century, others around 500, and still others with the replacement of written Late Latin by written Romance languages starting around the year 900. The terms Medieval Latin and Ecclesiastical Latin are sometimes used synonymously, though some scholars draw distinctions. Ecclesiastical Latin refers specifically to

682-517: A knowledge of Classical or Old Latin by the use of rare or archaic forms and sequences. Though they had not existed together historically, it is common that an author would use grammatical ideas of the two periods Republican and archaic, placing them equally in the same sentence. Also, many undistinguished scholars had limited education in "proper" Latin, or had been influenced in their writings by Vulgar Latin. Many striking differences between classical and Medieval Latin are found in orthography . Perhaps

Other jobs or roles may include sales and marketing of chemical products and chemistry-related instruments or technical writing. The more experience obtained, the more independence and leadership or management roles these chemists may perform in those organizations. Some chemists with relatively higher experience might change jobs or job position to become

806-497: A living language and was instead a scholarly language of the minority of educated men (and a tiny number of women) in medieval Europe, used in official documents more than for everyday communication. This resulted in two major features of Medieval Latin compared with Classical Latin, though when it is compared to the other vernacular languages, Medieval Latin developed very few changes. There are many prose constructions written by authors of this period that can be considered "showing off"

868-468: A manager of a chemistry-related enterprise, a supervisor, an entrepreneur or a chemistry consultant. Other chemists choose to combine their education and experience as a chemist with a distinct credential to provide different services (e.g., forensic chemists, chemistry-related software development, patent law specialists, environmental law firm staff, scientific news reporting staff, engineering design staff, etc.). In comparison, chemists who have obtained

930-553: A rebirth of Latin literature and learning after the depressed period following the final disintegration of the authority of the Western Roman Empire. Although it was simultaneously developing into the Romance languages, Latin itself remained very conservative, as it was no longer a native language and there were many ancient and medieval grammar books to give one standard form. On the other hand, strictly speaking there

At the Master's level and higher, students tend to specialize in a particular field. Fields of specialization include biochemistry , nuclear chemistry , organic chemistry , inorganic chemistry , polymer chemistry , analytical chemistry , physical chemistry , theoretical chemistry , quantum chemistry , environmental chemistry , and thermochemistry . Postdoctoral experience may be required for certain positions. Workers whose work involves chemistry, but not at

1178-1094: Is divided into several major sub-disciplines. There are also several main cross-disciplinary and more specialized fields of chemistry. There is a great deal of overlap between different branches of chemistry, as well as with other scientific fields such as biology, medicine, physics, radiology , and several engineering disciplines. All the above major areas of chemistry employ chemists. Other fields where chemical degrees are useful include astrochemistry (and cosmochemistry ), atmospheric chemistry , chemical engineering , chemo-informatics , electrochemistry , environmental science , forensic science , geochemistry , green chemistry , history of chemistry , materials science , medical science , molecular biology , molecular genetics , nanotechnology , nuclear chemistry , oenology , organometallic chemistry , petrochemistry , pharmacology , photochemistry , phytochemistry , polymer chemistry , supramolecular chemistry and surface chemistry .

1550-650: The Neo-Latin noun chimista , an abbreviation of alchimista ( alchemist ). Alchemists discovered many chemical processes that led to the development of modern chemistry. Chemistry as we know it today, was invented by Antoine Lavoisier with his law of conservation of mass in 1783. The discoveries of the chemical elements has a long history culminating in the creation of the periodic table by Dmitri Mendeleev . The Nobel Prize in Chemistry created in 1901 gives an excellent overview of chemical discovery since

1612-593: The syntax of some Medieval Latin writers, although Classical Latin continued to be held in high esteem and studied as models for literary compositions. The high point of the development of Medieval Latin as a literary language came with the Carolingian Renaissance , a rebirth of learning kindled under the patronage of Charlemagne , king of the Franks .

1984-590: The Latin vocabulary that developed for them became the source of a great many technical words in modern languages. English words like abstract , subject , communicate , matter , probable and their cognates in other European languages generally have the meanings given to them in Medieval Latin, often terms for abstract concepts not available in English. The influence of Vulgar Latin was also apparent in

However the use of quod to introduce subordinate clauses was especially pervasive and is found at all levels. Medieval Latin had ceased to be

2108-584: The classical Latin practice of generally placing the verb at the end, medieval writers would often follow the conventions of their own native language instead. Whereas Latin had no definite or indefinite articles, medieval writers sometimes used forms of unus as an indefinite article, and forms of ille (reflecting usage in the Romance languages) as a definite article or even quidam (meaning "a certain one/thing" in Classical Latin) as something like an article. Unlike classical Latin, where esse ("to be")

The higher the competency level achieved in the field of chemistry (as assessed via

3410-552: The use of medieval Latin among the learned elites of Christendom may have played a role in the spread of those features. In every age from the late 8th century onwards, there were learned writers (especially within the Church) who were familiar enough with classical syntax to be aware that these forms and usages were "wrong" and resisted their use. Thus the Latin of a theologian like St Thomas Aquinas or of an erudite clerical historian such as William of Tyre tends to avoid most of

After gold was discovered and became a precious metal, many people were interested to find a method that could convert other substances into gold. This led to the protoscience called alchemy . The word chemist is derived from

3534-419: Was also spread to areas such as Ireland and Germany , where Romance languages were not spoken, and which had never known Roman rule. Works written in those lands where Latin was a learned language, having no relation to the local vernacular, also influenced the vocabulary and syntax of Medieval Latin. Since subjects like science and philosophy, including Rhetoric and Ethics , were communicated in Latin,

Other important Insular authors include the historian Gildas ( c.  500  – c.  570 ) and the poet Aldhelm ( c.  640 –709). Benedict Biscop ( c.  628 –690) founded the monastery of Wearmouth-Jarrow and furnished it with books which he had taken home from a journey to Rome and which were later used by Bede ( c.  672 –735) to write his Ecclesiastical History of

3658-465: Was heavily influenced by the language of the Vulgate , which contained many peculiarities alien to Classical Latin that resulted from a more or less direct translation from Greek and Hebrew ; the peculiarities mirrored the original not only in its vocabulary but also in its grammar and syntax. Greek provided much of the technical vocabulary of Christianity . The various Germanic languages spoken by

3720-593: Was no single form of "Medieval Latin". Every Latin author in the medieval period spoke Latin as a second language, with varying degrees of fluency and syntax. Grammar and vocabulary, however, were often influenced by an author's native language. This was especially true beginning around the 12th century, after which the language became increasingly adulterated: late Medieval Latin documents written by French speakers tend to show similarities to medieval French grammar and vocabulary; those written by Germans tend to show similarities to German, etc. For instance, rather than following

Latin's use in universities was structured in lectures and debates, however, it was highly recommended that students use it in conversation. This practice was kept up only due to rules. One of Latin's purposes, writing, was still in practice; the main uses being charters for property transactions and to keep track of
