Animalcules
Animalcule ('little animal', from Latin ''animal'' + the diminutive suffix ''-culum'') is an old term for microscopic organisms that included bacteria, protozoans, and very small animals. The word was invented by 17th-century Dutch scientist Antonie van Leeuwenhoek to refer to the microorganisms he observed in rainwater. Some better-known types of animalcule include: * '' Actinophrys'', and other heliozoa, termed sun animalcules. * ''Amoeba'', termed ''Proteus'' animalcules. * ''Noctiluca scintillans'', commonly termed the sea sparkles. * ''Paramecium'', termed slipper animalcules. * '' Rotifers'', termed wheel animalcules. * ''Stentor'', termed trumpet animalcules. * ''Vorticella'', and other peritrichs, termed bell animalcules. The concept seems to have been proposed at least as early as about 30 BC, as evidenced by this translation from Marcus Varro's ''Rerum Rusticarum Libri Tres'': Note also if there be any swampy ground, both for the reasons given above, and because cer ...

Antonie Van Leeuwenhoek
Antonie Philips van Leeuwenhoek ( ; ; 24 October 1632 – 26 August 1723) was a Dutch microbiologist and microscopist in the Golden Age of Dutch science and technology. A largely self-taught man in science, he is commonly known as " the Father of Microbiology", and one of the first microscopists and microbiologists. Van Leeuwenhoek is best known for his pioneering work in microscopy and for his contributions toward the establishment of microbiology as a scientific discipline. Raised in Delft, Dutch Republic, van Leeuwenhoek worked as a draper in his youth and founded his own shop in 1654. He became well recognized in municipal politics and developed an interest in lensmaking. In the 1670s, he started to explore microbial life with his microscope. This was one of the notable achievements of the Golden Age of Dutch exploration and discovery (). Using single-lensed microscopes of his own design and make, van Leeuwenhoek was the first to observe and to experiment with micro ...

Paramecium
'' ''Paramecium'' ( , ; also spelled ''Paramoecium'') is a genus of eukaryotic, unicellular ciliates, commonly studied as a representative of the ciliate group. ''Paramecia'' are widespread in freshwater, brackish, and marine environments and are often very abundant in stagnant basins and ponds. Because some species are readily cultivated and easily induced to conjugate and divide, it has been widely used in classrooms and laboratories to study biological processes. Its usefulness as a model organism has caused one ciliate researcher to characterize it as the " white rat" of the phylum Ciliophora. Historical background ''Paramecia'' were among the first ciliates to be seen by microscopists, in the late 17th century. They were probably known to the Dutch pioneer of protozoology, Antonie van Leeuwenhoek, and were clearly described by his contemporary Christiaan Huygens in a letter of 1678. The earliest known illustration of a Paramecium was published anonymously in Philosophi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Henry Oldenburg
Henry Oldenburg (also Henry Oldenbourg) FRS (c. 1618 as Heinrich Oldenburg – 5 September 1677), was a German theologian, diplomat, and natural philosopher, known as one of the creators of modern scientific peer review. He was one of the foremost intelligencers of 17th-century Europe, with a network of correspondents to rival those of Fabri de Peiresc, Marin Mersenne, and Ismaël Boulliau. At the foundation of the Royal Society in London, he took on the task of foreign correspondence, as the first Secretary. Early life Born in Bremen, Germany, he was trained in theology and received his degree from the local ''Gymnasyum illustre'' on 2 November 1639. He had an initial very firm grasp of the German, Latin, and Greek languages. His movements during the 1640s are unclear, but he is thought to have worked as a tutor in England for much of the decade. In 1648 he left England and spent some time in Leiden and Utrecht in the Dutch Republic, where he became conversant in the Dutch ...

Microscopic Discovery Of Microorganisms
A microorganism, or microbe,, ''mikros'', "small") and ''organism'' from the el, ὀργανισμός, ''organismós'', "organism"). It is usually written as a single word but is sometimes hyphenated (''micro-organism''), especially in older texts. The informal synonym ''microbe'' () comes from μικρός, mikrós, "small" and βίος, bíos, "life". is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van Leeuwenhoek. In the 1850s, Louis Pasteur found that microorganisms caused food spoilage, debunking the theory of spontaneous generation. In the 1880s, Robert Koch discovered that microorganisms caused the diseases tuberculosis, cholera, diphtheria, and anthrax. Because micr ...

Infusoria
Infusoria are minute freshwater life forms including ciliates, euglenoids, protozoa, unicellular algae and small invertebrates. Some authors (e.g., Bütschli) used the term as a synonym for Ciliophora. In modern formal classifications, the term is considered obsolete; the microorganisms previously included in the Infusoria are mostly assigned to the kingdom Protista. Aquarium use Infusoria are used by owners of aquaria to feed fish fry; because of its small size it can be used to rear newly hatched fry of many common aquarium species. Many home aquaria are unable to naturally supply sufficient infusoria for fish-rearing, so hobbyists may create and maintain their own supply cultures or use one of the many commercial cultures available.Sharpe, Shirlie (December 22, 2018)"How to Culture Your Own Infusoria at Home" The Spruce Pets. Retrieved August 28, 2019. Infusoria can be cultured by soaking any decomposing vegetative matter such as papaya skin in a jar of aged (i.e., chlorine-fr ...

Caminalcule
Caminalcules are a fictive group of animal-like life forms, which were created as a tool for better understanding phylogenetics in real organisms. They were created by Joseph H. Camin (University of Kansas) and consist of 29 living 'species' and 48 fossil forms. The name of the taxon Caminalcules seems to come from Camin's last name and Antonie van Leeuwenhoek's animalcules. History Joseph H. Camin (1922–1979) drew the Caminalcules in the early 1960s or possibly even earlier to study the nature of taxonomic judgement. He assured that there was genetic continuity in the Caminalcules by the preservation of all characters except for changes that he desired in all successive animals. He did not keep track of the changes he made in the different species. The images of the Caminalcules were made using master stencils. The images of the living OTUs (29 species) were made available in the early 1960s; those of the fossil ones (48 species) later in the decade. These images were copied ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Major-General's Song
"I Am the Very Model of a Modern Major-General" (often referred to as the "Major-General's Song" or "Modern Major-General's Song") is a patter song from Gilbert and Sullivan's 1879 comic opera ''The Pirates of Penzance''. It has been called the most famous Gilbert and Sullivan patter song. Sung by Major-General Stanley at his first entrance, towards the end of Act I, the character introduces himself by presenting his résumé and admitting to a few shortcomings. The song satirises the idea of the "modern" educated British Army officer of the latter 19th century. The song is replete with historical and cultural references, in which the Major-General describes his impressive and well-rounded education in non-military matters, but he says that his military knowledge has "only been brought down to the beginning of the century". The stage directions in the libretto state that at the end of each verse the Major-General is "bothered for a rhyme". Interpolated business occurs here, and ...

The Pirates Of Penzance
''The Pirates of Penzance; or, The Slave of Duty'' is a comic opera in two acts, with music by Arthur Sullivan and libretto by W. S. Gilbert, W. S. Gilbert. Its official premiere was at the Fifth Avenue Theatre in New York City on 31 December 1879, where it was well received by both audiences and critics. Its London debut was on 3 April 1880, at the Opera Comique, where it ran for 363 performances. The story concerns Frederic, who, having completed his 21st year, is released from his apprenticeship to a band of tender-hearted pirates. He meets the daughters of Major-General Stanley, including Mabel, and the two young people fall instantly in love. Frederic soon learns, however, that he was born on the 29th of February, and so, technically, he has a birthday only once each leap year. His indenture specifies that he remain apprenticed to the pirates until his "twenty-first birthday", meaning that he must serve for another 63 years. Bound by his own sense of duty, Freder ...
