National Carbon Company
The National Carbon Company was founded in 1886 by the former Brush Electric Company executive W. H. Lawrence, in association with Myron T. Herrick, James Parmelee, and Webb Hayes, son of U.S. President Rutherford B. Hayes, in Cleveland, Ohio. In 1890, National Carbon merged with Thomson-Houston, Standard Carbon, and Faraday Carbon. History In 1894 the company began marketing Leclanché wet cells. At the same time, E. M. Jewett, was working in the company's Lakewood plant on the west side of Cleveland, under the direction of George Little. Jewett became interested in dry cells and, in his free time, conducted experiments in the laboratory. He developed a paper-lined, 1.5 volt cylindrical dry cell which he showed to Lawrence, who gave Jewett and Little a green light to begin manufacturing commercial dry cells. The trademark "Columbia" was proposed by Nelson C. Cotabish, a sales manager at NCC. In 1896 the company marketed the very first battery intended for widespread consumer ...

Applied Mathematics
Applied mathematics is the application of mathematical methods by different fields such as physics, engineering, medicine, biology, finance, business, computer science, and industry. Thus, applied mathematics is a combination of mathematical science and specialized knowledge. The term "applied mathematics" also describes the professional specialty in which mathematicians work on practical problems by formulating and studying mathematical models. In the past, practical applications have motivated the development of mathematical theories, which then became the subject of study in pure mathematics where abstract concepts are studied for their own sake. The activity of applied mathematics is thus intimately connected with research in pure mathematics. History Historically, applied mathematics consisted principally of applied analysis, most notably differential equations; approximation theory (broadly construed, to include representations, asymptotic methods, variational ...

Cornell Chronicle
The ''Cornell Chronicle'' is the in-house weekly newspaper published by Cornell University. History Prior to the founding of the ''Chronicle'' in 1969, campus news was reported by the ''Cornell Era'' and then by ''The Cornell Daily Sun''. During the Willard Straight Hall takeover in April 1969, the campus learned of unfolding events through the student-edited ''Sun'', the student radio station WVBR, and the independently owned ''Cornell Alumni News.'' However, Cornell's administration, most notably then-Vice President for Public Affairs Steven Muller, was dissatisfied because those media reported events in a manner that was somewhat critical of the administration. Over the summer, plans for the ''Chronicle'' were put in place and it debuted on September 25, 1969. The ''Chronicle''s first office was in the basement of the Edmund Ezra Day Edmund Ezra Day (December 7, 1883 – March 23, 1951) was an American educator. Day received his undergraduate and master's degrees f ...

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, ma ...

Klystron
A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian,Pond, Norman H. "The Tube Guys". Russ Cochran, 2008 p.31-40 which is used as an amplifier for high radio frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power klystrons are used as output tubes in UHF television transmitters, satellite communication, radar transmitters, and to generate the drive power for modern particle accelerators. In a klystron, an electron beam interacts with radio waves as it passes through resonant cavities, metal boxes along the length of a tube. The electron beam first passes through a cavity to which the input signal is applied. The energy of the electron beam amplifies the signal, and the amplified signal is taken from a cavity at the other end of the tube. The output signal can be coupled back into the input cavi ...

Doctoral Dissertation
A thesis ( : theses), or dissertation (abbreviated diss.), is a document submitted in support of candidature for an academic degree or professional qualification presenting the author's research and findings.International Standard ISO 7144: DocumentationâPresentation of theses and similar documents International Organization for Standardization, Geneva, 1986. In some contexts, the word "thesis" or a cognate is used for part of a bachelor's or master's course, while "dissertation" is normally applied to a doctorate. This is the typical arrangement in American English. In other contexts, such as within most institutions of the United Kingdom and Republic of Ireland, the reverse is true. The term graduate thesis is sometimes used to refer to both master's theses and doctoral dissertations. The required complexity or quality of research of a thesis or dissertation can vary by country, university, or program, and the required minimum study period may thus vary significantly in du ...

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...
