Arthur Edward Ruark
Arthur Edward Ruark (November 9, 1899 – 1979) was an American physicist and academic known for his role in the development of quantum mechanics. He wrote the book ''Atoms, Molecules, and Quanta'' with Nobel Prize in Chemistry winner Harold Clayton Urey in 1930, and is the author of numerous scientific papers on quantum physics. Early life and education Ruark was born in Washington, D.C., the son of Oliver Miles and Margaret Gordon Ruark (née Smith). He graduated from Towson High School in Maryland and attended Shepherd University. He received a Bachelor of Arts, Master of Arts, and PhD from Johns Hopkins University. Career He was a member of Atomic Structure Section of the National Bureau of Standards from 1922 to 1926. He was assistant professor of physics at Yale University from 1926 to 1927.

Quantum Physicists
In physics, a quantum (plural quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. The fundamental notion that a physical property can be "quantized" is referred to as "the hypothesis of quantization". This means that the magnitude of the physical property can take on only discrete values consisting of integer multiples of one quantum. For example, a photon is a single quantum of light (or of any other form of electromagnetic radiation). Similarly, the energy of an electron bound within an atom is quantized and can exist only in certain discrete values. (Atoms and matter in general are stable because electrons can exist only at discrete energy levels within an atom.) Quantization is one of the foundations of the much broader physics of quantum mechanics. Quantization of energy and its influence on how energy and matter interact (quantum electrodynamics) is part of the fundamental framework for understanding and describing nature. E ...

Shepherd University Alumni
A shepherd or sheepherder is a person who tends, herds, feeds, or guards flocks of sheep. ''Shepherd'' derives from Old English ''sceaphierde (''sceap'' 'sheep' + ''hierde'' 'herder'). ''Shepherding is one of the world's oldest occupations, it exists in all parts of the globe, and it is an important part of pastoralist animal husbandry. Because of the ubiquity of the profession, many religions and cultures have symbolic or metaphorical references to the shepherd profession. For example, Jesus called himself the Good Shepherd, and ancient Greek mythologies highlighted shepherds such as Endymion and Daphnis. This symbolism and shepherds as characters are at the center of pastoral literature and art. Origins Shepherding is among the oldest occupations, beginning some 5,000 years ago in Asia Minor. Sheep were kept for their milk, meat and especially their wool. Over the next thousand years, sheep and shepherding spread throughout Eurasia. Henri Fleisch tentatively suggested ...

Canton, New York
Canton is an incorporated town in St. Lawrence County, New York. The population was 11,638 at the time of the 2020 census. The town contains two villages: one also named Canton, the other named Rensselaer Falls. The town is named after the great port of Canton (now named Guangzhou) in China. Canton is the home of St. Lawrence University and the State University of New York at Canton. The Canton Central School District is based in the village of Canton. History Humans have been present in this region of New York since the Paleo-Indian period which is from about 15,000-7,000 BC. Iroquoian peoples arrived between 1,200 and 4,000 years ago, and both the Mohawk and the Oneida consider the Adirondacks to be part of their territory. When white settlers began to arrive, the area was part of the Mohawk Nation, which was part of the Iroquois Confederacy. The Mohawks are known as Kanienkehaka, or "the people of the flint," and they were considered the keepers of the Eastern door for t ...

Project Sherwood
Project Sherwood was the codename for a United States program in controlled nuclear fusion during the period it was classified. After 1958, when fusion research was declassified around the world, the project was reorganized as a separate division within the United States Atomic Energy Commission (AEC) and lost its codename. Sherwood developed out of a number of ''ad hoc'' efforts dating back to about 1951. Primary among these was the stellarator program at Princeton University, itself code-named Project Matterhorn. Since then the weapons labs had clamored to join the club, Los Alamos with its z-pinch efforts, Livermore's magnetic mirror program, and later, Oak Ridge's fuel injector efforts. By 1953 the combined budgets were increasing into the million dollar range, demanding some sort of oversight at the AEC level. The name "Sherwood" was suggested by Paul McDaniel, Deputy Director of the AEC. He noted that funding for the wartime Hood Building was being dropped and moved to th ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
