Navy Blue
Navy blue is a very dark shade of the color blue. Navy blue got its name from the dark blue (contrasted with naval white) worn by officers in the Royal Navy since 1748 and subsequently adopted by other navies around the world. When this color name, taken from the usual color of the uniforms of sailors, originally came into use in the early 19th century, it was initially called ''marine blue'', but the name of the color soon changed to ''navy blue''. An early use of ''navy blue'' as a color name in English was in 1840 though the ''Oxford English Dictionary'' has a citation from 1813. Variations Indigo dye Indigo dye is the color that is called ''Añil'' (the Spanish word for "indigo dye") in the ''Guía de coloraciones'' (''Guide to colorations'') by Rosa Gallego and Juan Carlos Sanz, a color dictionary published in 2005 that is widely popular in the Hispanophone realm. ''Indigo dye'' is the basis for all the historical navy blue colors, since in the 18th, 19th, and ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caduceus
The caduceus (☤; ; la, cādūceus, from grc-gre, κηρύκειον "herald's wand, or staff") is the staff carried by Hermes in Greek mythology and consequently by Hermes Trismegistus in Greco-Egyptian mythology. The same staff was also borne by heralds in general, for example by Iris, the messenger of Hera. It is a short staff entwined by two serpents, sometimes surmounted by wings. In Roman iconography, it was often depicted being carried in the left hand of Mercury, the messenger of the gods. Some accounts suggest that the oldest known imagery of the caduceus has its roots in Mesopotamia with the Sumerian god Ningishzida; his symbol, a staff with two snakes intertwined around it, dates back to 4000 BC to 3000 BC. As a symbolic object, it represents Hermes (or the Roman Mercury), and by extension trades, occupations, or undertakings associated with the god. In later Antiquity, the caduceus provided the basis for the astrological symbol representing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetite
Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe2+Fe3+2O4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. With the exception of extremely rare native iron deposits, it is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism. Magnetite is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and leaves a black streak. Small grains of magnetite are very common in igneous and metamorphic rocks. The chemical IUPAC name is iron(II,III) oxide and the common chemical name is ''ferrous-ferric oxide''. Properties In addition to igneous rocks, magnetite also occurs in sedimentary rocks, including banded iron formations and in lake and marine s ...

Greek Alphabet
The Greek alphabet has been used to write the Greek language since the late 9th or early 8th century BCE. It is derived from the earlier Phoenician alphabet, and was the earliest known alphabetic script to have distinct letters for vowels as well as consonants. In Archaic and early Classical times, the Greek alphabet existed in many local variants, but, by the end of the 4th century BCE, the Euclidean alphabet, with 24 letters, ordered from alpha to omega, had become standard and it is this version that is still used for Greek writing today. The uppercase and lowercase forms of the 24 letters are: : , , , , , , , , , , , , , , , , , /ς, , , , , , . The Greek alphabet is the ancestor of the Latin and Cyrillic scripts. Like Latin and Cyrillic, Greek originally had only a single form of each letter; it developed the letter case distinction between uppercase and lowercase in parallel with Latin during the modern era. Sound values and conventional transcriptions for s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrostatics
Electrostatics is a branch of physics that studies electric charges at rest ( static electricity). Since classical times, it has been known that some materials, such as amber, attract lightweight particles after rubbing. The Greek word for amber, (), was thus the source of the word 'electricity'. Electrostatic phenomena arise from the forces that electric charges exert on each other. Such forces are described by Coulomb's law. Even though electrostatically induced forces seem to be rather weak, some electrostatic forces are relatively large. The force between an electron and a proton, which together make up a hydrogen atom, is about 36 orders of magnitude stronger than the gravitational force acting between them. There are many examples of electrostatic phenomena, from those as simple as the attraction of plastic wrap to one's hand after it is removed from a package, to the apparently spontaneous explosion of grain silos, the damage of electronic components during manufac ...

Amber
Amber is fossilized tree resin that has been appreciated for its color and natural beauty since Neolithic times. Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects."Amber" (2004). In Maxine N. Lurie and Marc Mappen (eds.) ''Encyclopedia of New Jersey'', Rutgers University Press, . Amber is used in jewelry and has been used as a healing agent in folk medicine. There are five classes of amber, defined on the basis of their chemical constituents. Because it originates as a soft, sticky tree resin, amber sometimes contains animal and plant material as inclusions. Amber occurring in coal seams is also called resinite, and the term ''ambrite'' is applied to that found specifically within New Zealand coal seams. Etymology The English word ''amber'' derives from Arabic (ultimately from Middle Persian ''ambar'') via Middle Latin ''ambar'' and Middle French ''ambre''. The word was adopted in Middle English in the 14th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineering And Technology History Wiki
The Engineering and Technology History Wiki (ETHW) is a MediaWiki-based website dedicated to the history of technology. It started operating in 2015. It consists of articles, first-hand accounts, oral histories, landmarks and milestones. A partnership between the United Engineering Foundation (UEF) and its member engineering organizations ASCE, AIME, AIChE, ASME, IEEE as well as the Society of Women Engineers is developing the ETHW as a central repository for the documentation, analysis and explanation of the history of technology. Origins In September 2008, the ''IEEE History Committee'' founded the ''IEEE Global History Network'', which operated from 2008 to 2014. The ETHW became successor to the former ''IEEE Global History Network (IEEE GHN)''. Originally, the United Engineering Foundation had made a grant to develop an engineering intersociety web platform as a central historical repository. Initially, the work was mainly done at the IEEE History Center. annexed to the Ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dalhousie University
Dalhousie University (commonly known as Dal) is a large public research university in Nova Scotia, Canada, with three campuses in Halifax, a fourth in Bible Hill, and a second medical school campus in Saint John, New Brunswick. Dalhousie offers more than 4,000 courses, and over 200 degree programs in 13 undergraduate, graduate, and professional faculties. The university is a member of the U15, a group of research-intensive universities in Canada. The institution was established as ''Dalhousie College'', a nonsectarian institution established in 1818 by the eponymous Lieutenant Governor of Nova Scotia, George Ramsay, 9th Earl of Dalhousie, with education reformer, Dr. Thomas McCulloch, as its first principal. However, the college did not hold its first class until 1838, with operations remaining sporadic due to financial difficulties. The college was reorganized in 1863 and renamed ''The Governors of Dalhousie College and University''. The university formally changed its nam ...
