Karleton Armstrong
The Sterling Hall bombing occurred on the University of Wisconsin–Madison campus on August 24, 1970, and was committed by four men as an action against the university's research connections with the U.S. military during the Vietnam War. It resulted in the death of a university physics researcher and injuries to three others. Overview Sterling Hall is a centrally located building on the University of Wisconsin–Madison campus. The bomb, set off at 3:42 am on August 24, 1970, was intended to destroy the Army Mathematics Research Center (AMRC) housed on the 2nd, 3rd, and 4th floors of the building. It caused massive destruction to other parts of the building and nearby buildings as well. It resulted in the death of the researcher Robert Fassnacht, injured three others and caused significant destruction to the physics department and its equipment. Neither Fassnacht nor the physics department itself was involved with or employed by the Army Mathematics Research Center. The b ...

Opposition To United States Involvement In The Vietnam War
Opposition to United States involvement in the Vietnam War (before) or anti-Vietnam War movement (present) began with demonstrations in 1965 against the escalating role of the United States in the Vietnam War and grew into a broad social movement over the ensuing several years. This movement informed and helped shape the vigorous and polarizing debate, primarily in the United States, during the second half of the 1960s and early 1970s on how to end the war. Many in the peace movement within the United States were children, mothers, or anti-establishment youth. Opposition grew with participation by the African-American civil rights, second-wave feminist movements, Chicano Movements, and sectors of organized labor. Additional involvement came from many other groups, including educators, clergy, academics, journalists, lawyers, physicians such as Benjamin Spock, and military veterans. Their actions consisted mainly of peaceful, nonviolent events; few events were deliberately pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Oil
Fuel oil is any of various fractions obtained from the distillation of petroleum (crude oil). Such oils include distillates (the lighter fractions) and residues (the heavier fractions). Fuel oils include heavy fuel oil, marine fuel oil (MFO), bunker fuel, furnace oil (FO), gas oil (gasoil), heating oils (such as home heating oil), diesel fuel and others. The term ''fuel oil'' generally includes any liquid fuel that is burned in a furnace or boiler to generate heat (heating oils), or used in an engine to generate power (as motor fuels). However, it does not usually include other liquid oils, such as those with a flash point of approximately , or oils burned in cotton- or wool-wick burners. In a stricter sense, ''fuel oil'' refers only to the heaviest commercial fuels that crude oil can yield, that is, those fuels heavier than gasoline (petrol) and naphtha. Fuel oil consists of long-chain hydrocarbons, particularly alkanes, cycloalkanes, and aromatics. Small molecules, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Department Of Defense
The United States Department of Defense (DoD, USDOD or DOD) is an executive branch department of the federal government charged with coordinating and supervising all agencies and functions of the government directly related to national security and the United States Armed Forces. The DoD is the largest employer in the world, with over 1.34 million active-duty service members (soldiers, marines, sailors, airmen, and guardians) as of June 2022. The DoD also maintains over 778,000 National Guard and reservists, and over 747,000 civilians bringing the total to over 2.87 million employees. Headquartered at the Pentagon in Arlington, Virginia, just outside Washington, D.C., the DoD's stated mission is to provide "the military forces needed to deter war and ensure our nation's security". The Department of Defense is headed by the secretary of defense, a cabinet-level head who reports directly to the president of the United States. Beneath the Department of Defense are t ...

The Daily Cardinal
''The Daily Cardinal'' is a student newspaper that serves the University of Wisconsin–Madison community. One of the oldest student newspapers in the country, it began publishing on Monday, April 4, 1892. The newspaper is financially and editorially independent of the university. The ''Cardinals motto, printed at the bottom of every front page and taken from an 1894 declaration by the university's board of regents, is "...the great state University of Wisconsin should ever encourage that continual and fearless sifting and winnowing by which alone the truth can be found." Circulation ''The Daily Cardinal'' is published Thursdays during the academic year in a tabloid print format and maintains an independent website with fresh content each day. The print press run of 10,000 is distributed throughout the campus community. Nearly 200 undergraduate and graduate student volunteers and employees work at the paper. Its daily sections include News, Opinion, Arts and Sports, and its weekly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of t ...

Wisconsin Alumni Research Foundation
The Wisconsin Alumni Research Foundation is the independent nonprofit technology transfer organization serving the University of Wisconsin–Madison and Morgridge Institute for Research. It provides significant research support, granting tens of millions of dollars to the university each year and contributing to the university's "margin of excellence". History WARF was founded in 1925 to manage a discovery by Harry Steenbock, who invented the process for using ultraviolet radiation to add vitamin D to milk and other foods. Rather than leaving the invention unpatented—then the standard practice for university inventions—Steenbock used $300 of his own money to file for a patent. He received commercial interest from Quaker Oats but declined the company's initial offer. Instead, Steenbock sought a way to protect discoveries made by UW-Madison faculty, ensure use of the ideas for public benefit and bring any financial gains back to the university. His concept gained supp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Number Theory
Number theory (or arithmetic or higher arithmetic in older usage) is a branch of pure mathematics devoted primarily to the study of the integers and integer-valued functions. German mathematician Carl Friedrich Gauss (1777–1855) said, "Mathematics is the queen of the sciences—and number theory is the queen of mathematics."German original: "Die Mathematik ist die Königin der Wissenschaften, und die Arithmetik ist die Königin der Mathematik." Number theorists study prime numbers as well as the properties of mathematical objects made out of integers (for example, rational numbers) or defined as generalizations of the integers (for example, algebraic integers). Integers can be considered either in themselves or as solutions to equations (Diophantine geometry). Questions in number theory are often best understood through the study of analytical objects (for example, the Riemann zeta function) that encode properties of the integers, primes or other number-theoretic object ...

Kleene–Rosser Paradox
In mathematics, the Kleene–Rosser paradox is a paradox that shows that certain systems of formal logic are inconsistent, in particular the version of Haskell Curry's combinatory logic introduced in 1930, and Alonzo Church's original lambda calculus, introduced in 1932–1933, both originally intended as systems of formal logic. The paradox was exhibited by Stephen Kleene and J. B. Rosser in 1935. The paradox Kleene and Rosser were able to show that both systems are able to characterize and enumerate their provably total, definable number-theoretic functions, which enabled them to construct a term that essentially replicates Richard's paradox in formal language. Curry later managed to identify the crucial ingredients of the calculi that allowed the construction of this paradox, and used this to construct a much simpler paradox, now known as Curry's paradox. See also * List of paradoxes This list includes well known paradoxes, grouped thematically. The grouping is appr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosser's Trick
In mathematical logic, Rosser's trick is a method for proving Gödel's incompleteness theorems without the assumption that the theory being considered is ω-consistent (Smorynski 1977, p. 840; Mendelson 1977, p. 160). This method was introduced by J. Barkley Rosser in 1936, as an improvement of Gödel's original proof of the incompleteness theorems that was published in 1931. While Gödel's original proof uses a sentence that says (informally) "This sentence is not provable", Rosser's trick uses a formula that says "If this sentence is provable, there is a shorter proof of its negation". Background Rosser's trick begins with the assumptions of Gödel's incompleteness theorem. A theory T is selected which is effective, consistent, and includes a sufficient fragment of elementary arithmetic. Gödel's proof shows that for any such theory there is a formula \operatorname_T(x,y) which has the intended meaning that y is a natural number code (a Gödel number) for a ...
