Victor Lenzen
Victor Fritz Lenzen (14 December 1890, San Jose – 18 July 1975, Oakland) was an American physicist most noted for his logical rigour and commitment to teaching. His father was a building contractor. He went to Lick-Wilmerding High School, San Francisco where he developed an early interests in marine engineering, studying the armaments and the outfittings of all the capital ships in the world. He liked to take long walks around the nearby Hunter's Point. Although he started studying engineering at the University of California in 1909, he developed an interest in physics, but decided to major in philosophy. After graduating at the head of his class in 1913, he received a scholarship to Harvard from the San Francisco Harvard Club. He gained his Ph.D. in philosophy in 1916. Here he studied with Bertrand Russell and Josiah Royce, being influenced by their ideas on scientific methodology. He rejected Royce's idealism and developed his interest in physics, particularly with fundament ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Josiah Royce
Josiah Royce (; November 20, 1855 – September 14, 1916) was an American objective idealist philosopher and the founder of American idealism. His philosophical ideas included his version of personalism, defense of absolutism, idealism and his conceptualization of God. Royce's "A Word for the Times" (1914) was quoted in 1936 State of the Union Address by Franklin Delano Roosevelt: "The human race now passes through one of its great crises. New ideas, new issues – a new call for men to carry on the work of righteousness, of charity, of courage, of patience, and of loyalty. . . . I studied, I loved, I labored, unsparingly and hopefully, to be worthy of my generation." Royce is known as the only noted American philosopher who also studied and wrote history. His historical works mainly focused on the American West. Life Royce, born on November 20, 1855, in Grass Valley, California, was the son of Josiah and Sarah Eleanor (Bayliss) Royce, whose families were recent English emigr ...

1890 Births
Year 189 ( CLXXXIX) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Silanus and Silanus (or, less frequently, year 942 ''Ab urbe condita''). The denomination 189 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Thomas Corwin Mendenhall
Thomas Corwin Mendenhall (October 4, 1841 – March 23, 1924) was an American autodidact physicist and meteorologist. He was the first professor hired at Ohio State University in 1873 and the superintendent of the U.S. Coast and Geodetic Survey (now known as NOAA) from 1889 to 1894. Alongside his work, he was also an advocate for the adoption of the metric system by the United States and is the father of author profiling.

Coast And Geodetic Survey
The United States Coast and Geodetic Survey (abbreviated USC&GS), known from 1807 to 1836 as the Survey of the Coast and from 1836 until 1878 as the United States Coast Survey, was the first scientific agency of the United States Government. It existed from 1807 to 1970, and throughout its history was responsible for mapping and charting the coast of the United States, and later the coasts of U.S. territories. In 1871, it gained the additional responsibility of surveying the interior of the United States and geodesy became a more important part of its work, leading to it being renamed the U.S. Coast and Geodetic Survey in 1878. Long the U.S. Government's only scientific agency, the Survey accumulated other scientific and technical responsibilities as well, including astronomy, cartography, meteorology, geology, geophysics, hydrography, navigation, oceanography, exploration, pilotage, tides, and topography. It also was responsible for the standardization of weights and measures th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juliette Peirce
Juliette Peirce (; d. October 4, 1934) was the second wife of the mathematician and philosopher Charles Sanders Peirce. History Almost nothing is known about Juliette Peirce's life before she met Charles—not even her name, which is variously given as Juliette Annette Froissy or Juliette Pourtalai. Some historians believe she was French, but others have speculated that she had a Gypsy heritage (Ketner 1998, p. 279ff).Ketner, Kenneth Layne (1998), ''His Glassy Essence: An Autobiography of Charles Sanders Peirce'', Vanderbilt University Press, Nashville, TN, 416 pages, hardcover. Uses a fictional framing device, but most of the book presents Peirce's own words and the words of his family and friends. On occasion, she claimed to be a Habsburg princess.Brent 1998, p. 143.

Charles Peirce
Charles Sanders Peirce ( ; September 10, 1839 – April 19, 1914) was an American philosopher, logician, mathematician and scientist who is sometimes known as "the father of pragmatism". Educated as a chemist and employed as a scientist for thirty years, Peirce made major contributions to logic, a subject that, for him, encompassed much of what is now called epistemology and the philosophy of science. He saw logic as the formal branch of semiotics, of which he is a founder, which foreshadowed the debate among logical positivists and proponents of philosophy of language that dominated 20th-century Western philosophy. Additionally, he defined the concept of abductive reasoning, as well as rigorously formulated mathematical induction and deductive reasoning. As early as 1886, he saw that logical operations could be carried out by electrical switching circuits. The same idea was used decades later to produce digital computers.

Kant
Immanuel Kant (, , ; 22 April 1724 – 12 February 1804) was a German Philosophy, philosopher and one of the central Age of Enlightenment, Enlightenment thinkers. Born in Königsberg, Kant's comprehensive and systematic works in epistemology, metaphysics, ethics, and aesthetics have made him one of the most influential figures in modern Western philosophy. In his doctrine of transcendental idealism, Kant argued that space and time are mere "forms of intuition" which structure all experience, and therefore that, while "Thing-in-itself, things-in-themselves" exist and contribute to experience, they are nonetheless distinct from the objects of experience. From this it follows that the objects of experience are mere "appearances", and that the nature of things as they are in themselves is unknowable to us. In an attempt to counter the Philosophical skepticism, skepticism he found in the writings of philosopher David Hume, he wrote the ''Critique of Pure Reason'' (1781/1787), on ...

Bertrand Russell
Bertrand Arthur William Russell, 3rd Earl Russell, (18 May 1872 – 2 February 1970) was a British mathematician, philosopher, logician, and public intellectual. He had a considerable influence on mathematics, logic, set theory, linguistics, artificial intelligence, cognitive science, computer science and various areas of analytic philosophy, especially philosophy of mathematics, philosophy of language, epistemology, and metaphysics.Stanford Encyclopedia of Philosophy"Bertrand Russell" 1 May 2003. He was one of the early 20th century's most prominent logicians, and a founder of analytic philosophy, along with his predecessor Gottlob Frege, his friend and colleague G. E. Moore and his student and protégé Ludwig Wittgenstein. Russell with Moore led the British "revolt against idealism". Together with his former teacher A. N. Whitehead, Russell wrote ''Principia Mathematica'', a milestone in the development of classical logic, and a major attempt to reduce the whole ...

Oakland
Oakland is the largest city and the county seat of Alameda County, California, United States. A major West Coast port, Oakland is the largest city in the East Bay region of the San Francisco Bay Area, the third largest city overall in the Bay Area and the eighth most populated city in California. With a population of 440,646 in 2020, it serves as the Bay Area's trade center and economic engine: the Port of Oakland is the busiest port in Northern California, and the fifth busiest in the United States of America. An act to incorporate the city was passed on May 4, 1852, and incorporation was later approved on March 25, 1854. Oakland is a charter city. Oakland's territory covers what was once a mosaic of California coastal terrace prairie, oak woodland, and north coastal scrub. In the late 18th century, it became part of a large ''rancho'' grant in the colony of New Spain. Its land served as a resource when its hillside oak and redwood timber were logged to build San Francisc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
