Charles Thomas Jackson
Charles Thomas Jackson (June 21, 1805 – August 28, 1880) was an American physician and scientist who was active in medicine, chemistry, mineralogy, and geology. Life and work Born at Plymouth, Massachusetts, of a prominent New England family, he was a brother-in-law of Ralph Waldo Emerson and a graduate of the Harvard Medical School in 1829, where he won the Boylston prize for his dissertation. While at Harvard he made a geological exploration of Nova Scotia with his friend Francis Alger of Boston, which helped to increasingly turn his interests toward geology. In 1829, he traveled to Europe where he studied both medicine and geology for several years and made the acquaintance of prominent European scientists and physicians. Upon returning to the United States he played an active role in the new state geological survey movement, serving successively between 1836 and 1844 as the state geologist of Maine, Rhode Island, and New Hampshire. In 1844–45, he was an on-site minin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plymouth, Massachusetts
Plymouth (; historically known as Plimouth and Plimoth) is a town in Plymouth County, Massachusetts, United States. Located in Greater Boston, the town holds a place of great prominence in American history, folklore, and culture, and is known as "America's Hometown". Plymouth was the site of the colony founded in 1620 by the ''Mayflower'' Pilgrims, where New England was first established. It is the oldest municipality in New England and one of the oldest in the United States. The town has served as the location of several prominent events, one of the more notable being the First Thanksgiving feast. Plymouth served as the capital of Plymouth Colony from its founding in 1620 until the colony's merger with the Massachusetts Bay Colony in 1691. The English explorer John Smith named the area Plymouth (after the city in South West England) and the region 'New England' during his voyage of 1614 (the accompanying map was published in 1616). It was a later coincidence that, after an ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Auburn Cemetery
Mount Auburn Cemetery is the first rural cemetery, rural, or garden, cemetery in the United States, located on the line between Cambridge, Massachusetts, Cambridge and Watertown, Massachusetts, Watertown in Middlesex County, Massachusetts, Middlesex County, Massachusetts, west of Boston. It is the burial site of many prominent Boston Brahmins, as well as being a National Historic Landmark. Dedicated in 1831 and set with classical monuments in a rolling landscaped terrain, it marked a distinct break with Colonial-era burying grounds and church-affiliated graveyards. The appearance of this type of landscape coincides with the rising popularity of the term "cemetery," derived from the Greek language, Greek for "a sleeping place," instead of graveyard. This language and outlook eclipsed the previous harsh view of death and the afterlife embodied by old graveyards and church burial plots. The cemetery is important both for its historical aspects and for its role as an arboretum. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Douglass Houghton (September 21, 1809 – October 13, 1845) was an American geologist and physician, primarily known for his exploration of the Keweenaw Peninsula of Michigan. It was the site of a copper boom and extensive copper mining beginning in the 19th century. He was appointed in 1839 as the first state geologist of Michigan, after it was admitted to the union, and served in that position for the rest of his life.

Diethyl Ether
Diethyl ether, or simply ether, is an organic compound in the ether class with the formula , sometimes abbreviated as (see Pseudoelement symbols). It is a colourless, highly volatile, sweet-smelling ("ethereal odour"), extremely flammable liquid. It is commonly used as a solvent in laboratories and as a starting fluid for some engines. It was formerly used as a general anesthetic, until non-flammable drugs were developed, such as halothane. It has been used as a recreational drug to cause intoxication. Production Most diethyl ether is produced as a byproduct of the vapor-phase hydration of ethylene to make ethanol. This process uses solid-supported phosphoric acid catalysts and can be adjusted to make more ether if the need arises. Vapor-phase dehydration of ethanol over some alumina catalysts can give diethyl ether yields of up to 95%. Diethyl ether can be prepared both in laboratories and on an industrial scale by the acid ether synthesis. Ethanol is mixed with a stro ...

Anesthesia
Anesthesia is a state of controlled, temporary loss of sensation or awareness that is induced for medical or veterinary purposes. It may include some or all of analgesia (relief from or prevention of pain), paralysis (muscle relaxation), amnesia (loss of memory), and unconsciousness. An individual under the effects of anesthetic drugs is referred to as being anesthetized. Anesthesia enables the painless performance of procedures that would otherwise cause severe or intolerable pain in a non-anesthetized individual, or would otherwise be technically unfeasible. Three broad categories of anesthesia exist: * General anesthesia suppresses central nervous system activity and results in unconsciousness and total lack of sensation, using either injected or inhaled drugs. * Sedation suppresses the central nervous system to a lesser degree, inhibiting both anxiety and creation of long-term memories without resulting in unconsciousness. * Regional and local anesthesia, which blo ...

Digestion
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream. Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion. The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. Mechanical digestion takes place in the mouth through mastication and in the small intestine through segmentation contractions. In chemical digestion, enzymes break down food into the small molecules the body can use. In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a form of mechanical digestion, and the wetting contact o ...
