Gustaf Wilhelm Hammar
Gustaf Wilhelm Hammar (Gustav Vilhelm Hammar) (June 22, 1893 – August 19, 1954) was a Swedish-born American experimental physicist. He was the eldest of six children of Anders Vilhelm Hammar and Elin Christina Hammar (née Olsson). He emigrated to the United States in 1913, attended Bethel University in St. Paul, Minnesota, and by 1920 was married and living with his wife, Louise (with whom he was ultimately to have four children), in King County, Washington. He obtained his M.S. degree at the University of Idaho in 1924 and a Ph.D. from the California Institute of Technology in 1927. His Ph.D. dissertation topic was titled "Magnetic Susceptibilities of Some Common Gases." He returned to the University of Idaho in 1926 to teach, and became the head of the physics department in 1930, a position that he held for sixteen years. He led a productive materials science laboratory and was mindful of practical applications of his research—for example, as an extension of his re ...

Bethel University (Minnesota)
Bethel University is a private Christian university and seminary in Arden Hills, Minnesota. It was founded in 1871 as a seminary and is affiliated with Converge. The university enrolls 5,600 students in undergraduate, graduate, and seminary programs. Its main campus is situated on about 290 acres on the east side of Lake Valentine just south of Interstate 694. History Bethel University has its origins in the Baptist Theological Union's Swedish Seminary, which was founded by Swedish Baptist pastor John Alexis Edgren in Chicago, Illinois in 1871. In 1914, the Baptist General Conference has become the school's main partner.Randall Herbert Balmer, ''Encyclopedia of Evangelicalism: Revised and expanded edition'', Baylor University Press, USA, 2004, p. 74 The seminary merged with Bethel Academy and relocated its campus to Saint Paul, Minnesota. In 1931, the Academy became Bethel Junior College. The addition of a four-year liberal arts college program created ''Bethel College and Sem ...

Military Deception
Military deception (MILDEC) is an attempt by a military unit to gain an advantage during warfare by misleading adversary decision makers into taking action or inaction that creates favorable conditions for the deceiving force. This is usually achieved by creating or amplifying an artificial fog of war via psychological operations, information warfare, visual deception, or other methods. As a form of disinformation, it overlaps with psychological warfare. Military deception is also closely connected to operations security (OPSEC) in that OPSEC attempts to conceal from the adversary critical information about an organization's capabilities, activities, limitations, and intentions, or provide a plausible alternate explanation for the details the adversary can observe, while deception reveals false information in an effort to mislead the adversary. Deception in warfare dates back to early history. ''The Art of War'', an ancient Chinese military treatise, emphasizes the importance of ...

Experimental Physicists
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into Causality, cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experiment, natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Physical Society
The American Physical Society (APS) is a not-for-profit membership organization of professionals in physics and related disciplines, comprising nearly fifty divisions, sections, and other units. Its mission is the advancement and diffusion of knowledge of physics. The society publishes more than a dozen scientific journals, including the prestigious '' Physical Review'' and ''Physical Review Letters'', and organizes more than twenty science meetings each year. APS is a member society of the American Institute of Physics. Since January 2021 the organization has been led by chief executive officer Jonathan Bagger. History The American Physical Society was founded on May 20, 1899, when thirty-six physicists gathered at Columbia University for that purpose. They proclaimed the mission of the new Society to be "to advance and diffuse the knowledge of physics", and in one way or another the APS has been at that task ever since. In the early years, virtually the sole activity of the AP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Night Vision Device
A night-vision device (NVD), also known as a night optical/observation device (NOD), night-vision goggle (NVG), is an optoelectronic device that allows visualization of images in low levels of light, improving the user's night vision. The device enhances ambient visible light and converts near-infrared light into visible light which can be seen by the user; this is known as I2 ( image intensification). By comparison, viewing of infrared thermal radiation is referred to as thermal imaging and operates in a different section of the infrared spectrum. A night vision device usually consists of an image intensifier tube, a protective housing, and may have some type of mounting system. Many NVDs also include a protective sacrificial lens, mounted over the front lens (ie. objective lens) on NVDs to protect the latter from damage by environmental hazards and some can incorporate [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King County, Washington
King County is located in the U.S. state of Washington. The population was 2,269,675 in the 2020 census, making it the most populous county in Washington, and the 13th-most populous in the United States. The county seat is Seattle, also the state's most populous city. King County is one of three Washington counties that are included in the Seattle– Tacoma–Bellevue metropolitan statistical area. (The others are Snohomish County to the north, and Pierce County to the south.) About two-thirds of King County's population lives in Seattle's suburbs. History When Europeans arrived in the region that would become King County, it was inhabited by several Coast Salish groups. Villages around the site that would become Seattle were primarily populated by the Duwamish people. The Snoqualmie Indian Tribe occupied the area that would become eastern King County. The Green River and White River were home for the Muckleshoot tribal groups. In the first winter after the Denny Party lande ...
