Harold F. Blum
Harold Francis Blum (1899 - 1980) was a physiologist who explored the interaction of light and chemicals on cells, especially sunlight-induced skin cancer. Early life and education Harold Blum was born on February 12, 1899, in Escondido, California. For a year during the First World War, he served with the American Expeditionary Forces Signal Corps in France. Blum graduated in 1922 from the University of California, Berkeley, with an A.B. in zoology with honors. He attended Harvard Medical School from 1923 to 1924, then returned to Berkeley for a Ph.D. in physiology and graduated in 1927. During his PhD studies Blum worked for the San Francisco Bay Marine Piling Committee. Blum completed postdoctoral studies at the Laboratoire Maritime de Concarneau in France and the University of Liège in Belgium in 1933. Career Harold Blum was an assistant professor of animal biology at the University of Oregon, then an instructor of physiology at Harvard Medical School. He became an assist ...

Escondido, California
Escondido is a city in San Diego County, California, United States. Located in the North County region, it was incorporated in 1888, and is one of the oldest cities in San Diego County. It has a population of 151,038 as of the 2020 census. Etymology "Escondido" is a Spanish word meaning "hidden". One source says the name originally referred to ''agua escondida'' or hidden water; another says it meant "hidden treasure". The city is known as ''Eskondiid'' in Kumeyaay. History The Escondido area was first settled by the Luiseño, who established campsites and villages along the creek running through the area. They named the place Mixéelum Pompáwvo or "Mehel-om-pom-pavo." The Luiseno also had another village north of Mixéelum Pompáwvo called Panakare. The Kumeyaay migrated from areas near the Colorado River, settling both in the San Pasqual Valley and near the San Dieguito River in the southwestern and western portions of what is now Escondido. Most of the villages and campsi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Expeditionary Forces
The American Expeditionary Forces (A. E. F.) was a formation of the United States Army on the Western Front of World War I. The A. E. F. was established on July 5, 1917, in France under the command of General John J. Pershing. It fought alongside French Army, British Army, Canadian Army, New Zealand Army and Australian Army units against the Imperial German Army. A small number of A. E. F. troops also fought alongside Italian Army units in that same year against the Austro-Hungarian Army. The A. E. F. helped the French Army on the Western Front during the Aisne Offensive (at the Battle of Château-Thierry and Battle of Belleau Wood) in the summer of 1918, and fought its major actions in the Battle of Saint-Mihiel and the Meuse-Argonne Offensive in the latter part of 1918. Formation President Woodrow Wilson initially planned to give command of the A. E. F. to Gen. Frederick Funston, but after Funston's sudden death, Wilson appointed Major General John J. Pershing in Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermodynamic
Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation. The behavior of these quantities is governed by the four laws of thermodynamics which convey a quantitative description using measurable macroscopic physical quantities, but may be explained in terms of microscopic constituents by statistical mechanics. Thermodynamics applies to a wide variety of topics in science and engineering, especially physical chemistry, biochemistry, chemical engineering and mechanical engineering, but also in other complex fields such as meteorology. Historically, thermodynamics developed out of a desire to increase the efficiency of early steam engines, particularly through the work of French physicist Sadi Carnot (1824) who believed that engine efficiency was the key that could help France win the Napoleonic Wars. Scots-Irish physicist Lord Kelvin was the first to formulate a co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Negentropy
In information theory and statistics, negentropy is used as a measure of distance to normality. The concept and phrase "negative entropy" was introduced by Erwin Schrödinger in his 1944 popular-science book ''What is Life?'' Later, Léon Brillouin shortened the phrase to ''negentropy''. In 1974, Albert Szent-Györgyi proposed replacing the term ''negentropy'' with ''syntropy''. That term may have originated in the 1940s with the Italian mathematician Luigi Fantappiè, who tried to construct a unified theory of biology and physics. Buckminster Fuller tried to popularize this usage, but ''negentropy'' remains common. In a note to ''What is Life?'' Schrödinger explained his use of this phrase. Information theory In information theory and statistics, negentropy is used as a measure of distance to normality. Out of all distributions with a given mean and variance, the normal or Gaussian distribution is the one with the highest entropy. Negentropy measures the difference in entrop ...

Organic Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. The theory of evolution by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arrow Of Time
The arrow of time, also called time's arrow, is the concept positing the "one-way direction" or " asymmetry" of time. It was developed in 1927 by the British astrophysicist Arthur Eddington, and is an unsolved general physics question. This direction, according to Eddington, could be determined by studying the organization of atoms, molecules, and bodies, and might be drawn upon a four-dimensional relativistic map of the world ("a solid block of paper"). Physical processes at the microscopic level are believed to be either entirely or mostly time-symmetric: if the direction of time were to reverse, the theoretical statements that describe them would remain true. Yet at the macroscopic level it often appears that this is not the case: there is an obvious direction (or ''flow'') of time. Overview The symmetry of time (T-symmetry) can be understood simply as the following: if time were perfectly symmetrical, a video of real events would seem realistic whether played forward ...

Guggenheim Fellowships
Guggenheim Fellowships are grants that have been awarded annually since by the John Simon Guggenheim Memorial Foundation to those "who have demonstrated exceptional capacity for productive scholarship or exceptional creative ability in the arts." Each year, the foundation issues awards in each of two separate competitions: * One open to citizens and permanent residents of the United States and Canada. * The other to citizens and permanent residents of Latin America and the Caribbean. The Latin America and Caribbean competition is currently suspended "while we examine the workings and efficacy of the program. The U.S. and Canadian competition is unaffected by this suspension." The performing arts are excluded, although composers, film directors, and choreographers are eligible. The fellowships are not open to students, only to "advanced professionals in mid-career" such as published authors. The fellows may spend the money as they see fit, as the purpose is to give fellows "b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
