Horace Wells
Horace Wells (January 21, 1815 – January 24, 1848) was an American dentist who pioneered the use of anesthesia in dentistry, specifically the use of nitrous oxide (or laughing gas). Early life Wells was the first of three children of Horace and Betsy Heath Wells, born on January 21, 1815 in Hartford, Vermont. His parents were well-educated and affluent land owners, which allowed him to attend private schools in New Hampshire and Amherst, Massachusetts. At the age of 19 in 1834, Wells began studying dentistry under a two-year apprenticeship in Boston. The first dental school did not open until 1840 in Baltimore. At age 23, Wells published a booklet "An Essay on Teeth" in which he advocated for his ideas in preventive dentistry, particularly for the use of a toothbrush. In his booklet, he also described tooth development and oral diseases, where he mentioned diet, infection, and oral hygiene as important factors. After obtaining a degree, Wells set up a practice in Hart ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sulfuric Acid
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid ( Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula . It is a colorless, odorless and viscous liquid that is miscible with water. Pure sulfuric acid does not exist naturally on Earth due to its strong affinity to water vapor; it is hygroscopic and readily absorbs water vapor from the air. Concentrated sulfuric acid is highly corrosive towards other materials, from rocks to metals, since it is an oxidant with powerful dehydrating properties. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid, but to the contrary dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is released; thus the reverse procedure of adding water to the acid should not be performed since the heat released ...

Humphry Davy
Sir Humphry Davy, 1st Baronet, (17 December 177829 May 1829) was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp. He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine. Davy also studied the forces involved in these separations, inventing the new field of electrochemistry. Davy is also credited to have been the first to discover clathrate hydrates in his lab. In 1799 he experimented with nitrous oxide and was astonished at how it made him laugh, so he nicknamed it "laughing gas" and wrote about its potential anaesthetic properties in relieving pain during surgery. Davy was a baronet, President of the Royal Society (PRS), Member of the Royal Irish Academy (MRIA), Fellow of the Geological Society (FGS), and a mem ...

Self-experimentation
Self-experimentation refers to the special case of single-subject research in which the experimenter conducts the experiment on themselves. Usually this means that a single person is the designer, operator, subject, analyst, and user or reporter of the experiment. Also referred to as Personal science or N-of-1 research, self-experimentation is an example of citizen science, since it can also be led by patients or people interested in their own health and well-being, as both research subjects and self-experimenters. Current pioners and practitioners of self-experimentation include the late Seth Roberts, Tim Ferriss, and a sprawling community of Quantified Self. Biology and medicine Human scientific self-experimentation principally (though not necessarily) falls into the fields of medicine and psychology. Self-experimentation has a long and well-documented history in medicine which continues to the present day. For example, after failed attempts to infect piglets in 1984, B ...
