Brookfield, Massachusetts
Brookfield is a town in Worcester County, Massachusetts, United States. Brookfield was first settled by Europeans in 1660. The population was 3,439 at the 2020 census. History Brookfield was first settled by Europeans in 1660 and was officially incorporated in 1718. The town was settled by men from Ipswich as part of the Quaboag Plantation lands. In August 1675, King Philip's War reached central Massachusetts. Brookfield, one of the most isolated settlements in the colony, was attacked by Nipmuck forces. After an ambush, the town was besieged. For two days the townsfolk, consisting of 80 people, sought shelter in the garrison house while the rest of the town was completely destroyed. The settlement lay abandoned for twelve years. During the winter of 1776, General Henry Knox passed through the town with cannon from Fort Ticonderoga to end the Siege of Boston. A marker along Route 9 commemorates his route. Bathsheba Spooner In March 1778, Joshua Spooner, a wealthy farme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanologist
A volcanologist, or volcano scientist, is a geologist who focuses on understanding the formation and eruptive activity of volcanoes. Volcanologists frequently visit volcanoes, sometimes active ones, to observe and monitor volcanic eruptions, collect eruptive products including tephra (such as Volcanic ash, ash or pumice), Rock (geology), rock and lava samples. One major focus of inquiry in recent times is the prediction of eruptions to alleviate the impact on surrounding populations and monitor natural hazards associated with volcanic activity. Geologists who research volcanic materials that make up the solid Earth are referred to as igneous petrologists. Etymology The word ''volcanologist'' (or ''vulcanologist'') is derived from the English volcanology (volcano + wikt:-logy, -logy), which was derived from the French wikt:volcanologie#French, volcanologie (or vulcanologie), which was further derived from the French word wikt:volcan#French, volcan (volcano), which was even furt ...

Hendrik Willem Bakhuis Roozeboom
Hendrik Willem Bakhuis Roozeboom (; October 24, 1854 – February 8, 1907) was a Dutch chemist who studied phase behaviour in physical chemistry. Education and career Bakhuis Roozeboom (originally "Bakhuys Roozeboom") was born in Alkmaar in the Netherlands. Financial difficulties did not allow him to directly pursue a university education, and he left school to work in a chemical factory for some time. Due to support from his mentor, J. M. van Bemmelen, he became an assistant at the University of Leiden in 1878, which enabled him to start his academic education there. In 1881 he became a teacher at a girls school, and in 1884 he obtained his PhD with works on the hydrates of acids. J. D. van der Waals introduced him to the theoretical works of J. Willard Gibbs on the phase rule which so far had little experimental verification in chemistry, prompting him to start a lifelong research program on phase equilibria. In 1896, he became professor for chemistry at the University of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Society Of America
The Geological Society of America (GSA) is a nonprofit organization dedicated to the advancement of the geosciences. History The society was founded in Ithaca, New York, in 1888 by Alexander Winchell, John J. Stevenson, Charles H. Hitchcock, John R. Procter and Edward Orton and has been headquartered at 3300 Penrose Place, Boulder, Colorado, US, since 1967. GSA began with 100 members under its first president, James Hall. In 1889 Mary Emilie Holmes became its first female member. It grew slowly but steadily to 600 members until 1931, when a nearly $4 million endowment from 1930 president R. A. F. Penrose Jr. jumpstarted GSA's growth. As of December 2017, GSA had more than 25,000 members in over 100 countries. The society has six regional sections in North America, three interdisciplinary interest groups, and eighteen specialty divisions. Activities The stated mission of GSA is "to advance geoscience research and discovery, service to society, stewardship of Ear ...

Electrolytes
An electrolyte is a substance that conducts electricity through the movement of ions, but not through the movement of electrons. This includes most soluble salts, acids, and bases, dissolved in a polar solvent like water. Upon dissolving, the substance separates into cations and anions, which disperse uniformly throughout the solvent. Solid-state electrolytes also exist. In medicine and sometimes in chemistry, the term electrolyte refers to the substance that is dissolved. Electrically, such a solution is neutral. If an electric potential is applied to such a solution, the cations of the solution are drawn to the electrode that has an abundance of electrons, while the anions are drawn to the electrode that has a deficit of electrons. The movement of anions and cations in opposite directions within the solution amounts to a current. Some gases, such as hydrogen chloride (HCl), under conditions of high temperature or low pressure can also function as electrolytes. Electroly ...

Conductive
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of Electric charge, charge (electric current) in one or more directions. Materials made of metal are common electrical conductors. The flow of negatively charged electrons generates electric current, positively charged Electron hole, holes, and positive or negative ions in some cases. In order for current to flow within a closed Electrical network, electrical circuit, one charged particle does not need to travel from the component producing the current (the current source) to those consuming it (the Electrical load, loads). Instead, the charged particle simply needs to nudge its neighbor a finite amount, who will nudge ''its'' neighbor, and on and on until a particle is nudged into the consumer, thus powering it. Essentially what is occurring is a long chain of momentum transfer between mobile charge carriers; the Drude model of conduction describes this process more rigorous ...

Friedrich Kohlrausch (physicist)
Friedrich Wilhelm Georg Kohlrausch (14 October 1840 – 17 January 1910) was a German physicist who investigated the conductive properties of electrolytes and contributed to knowledge of their behaviour. He also investigated elasticity, thermoelasticity, and thermal conduction as well as magnetic and electrical precision measurements. Nowadays, Friedrich Kohlrausch is classed as one of the most important experimental physicists. His early work helped to extend the absolute system of Carl Friedrich Gauss and Wilhelm Weber to include electrical and magnetic measuring units. Biography Education Son of Rudolf Kohlrausch, Friedrich Wilhelm Georg Kohlrausch was born on October 14, 1840, in Rinteln, Germany. After studying physics at Erlangen and Göttingen, Friedrich Kohlrausch completed his doctorate in Göttingen. Teaching After a two-year work as a lecturer in Frankfurt, Kohlrausch was appointed a professor of physics at the University of Göttingen (1866–70). During 1870 Ko ...

Honorary Doctorate
An honorary degree is an academic degree for which a university (or other degree-awarding institution) has waived all of the usual requirements. It is also known by the Latin phrases ''honoris causa'' ("for the sake of the honour") or '' ad honorem '' ("to the honour"). The degree is typically a doctorate or, less commonly, a master's degree, and may be awarded to someone who has no prior connection with the academic institution or no previous postsecondary education. An example of identifying a recipient of this award is as follows: Doctorate in Business Administration (''Hon. Causa''). The degree is often conferred as a way of honouring a distinguished visitor's contributions to a specific field or to society in general. Honorary doctorates are purely titular degrees in that they confer no rights on the recipient and carry with them no formal academic qualification. As such, it is always expected that such degrees be listed in one's curriculum vitae (CV) as an award, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doctor Of Philosophy
A Doctor of Philosophy (PhD, DPhil; or ) is a terminal degree that usually denotes the highest level of academic achievement in a given discipline and is awarded following a course of Postgraduate education, graduate study and original research. The name of the degree is most often abbreviated PhD (or, at times, as Ph.D. in North American English, North America), pronounced as three separate letters ( ). The University of Oxford uses the alternative abbreviation "DPhil". PhDs are awarded for programs across the whole breadth of academic fields. Since it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and, in some cases, defend their work before a panel of other experts in the field. In many fields, the completion of a PhD is typically required for employment as a university professor, researcher, or scientist. Definition In the context o ...
