Mass Shootings In The United States
Mass shootings are incidents involving multiple victims of Gun violence in the United States, firearm-related violence. Definitions vary, with no single, broadly accepted definition. One definition is an act of public firearm violence—excluding gang killings, domestic violence, or terrorist acts sponsored by an organization—in which a shooter kills at least four victims. Using this definition, one study found that nearly one-third of the world's public mass shootings between 1966 and 2012 (90 of 292 incidents) occurred in the United States. Using a similar definition, ''The Washington Post'' records 163 mass shootings in the United States between 1967 and June 2019. Mother Jones (magazine), ''Mother Jones'' records 133 mass shootings between 1982 and July 2022. ''The Associated Press'' records 59 mass shootings between 2006 and August 2022. ''The New York Times'' records 90 mass shootings between 1966 and 2012. ''The Violence Project'' records 185 mass shootings from 1966 to ...

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 ...

Space Plasma
The interplanetary medium (IPM) or interplanetary space consists of the mass and energy which fills the Solar System, and through which all the larger Solar System bodies, such as planets, dwarf planets, asteroids, and comets, move. The IPM stops at the heliopause, outside of which the interstellar medium begins. Before 1950, interplanetary space was widely considered to either be an empty vacuum, or consisting of " aether". Composition and physical characteristics The interplanetary medium includes interplanetary dust, cosmic rays, and hot plasma from the solar wind. The temperature of the interplanetary medium varies. For dust particles within the asteroid belt, typical temperatures range from 200 K (−73 °C) at 2.2 AU down to 165 K (−108 °C) at 3.2 AU. The density of the interplanetary medium is very low, decreasing in inverse proportion to the square of the distance from the Sun. It is variable, and may be affected by magnetic fields and e ...

Des Moines Register
''The Des Moines Register'' is the daily morning newspaper of Des Moines, Iowa. History Early period The first newspaper in Des Moines was the ''Iowa Star''. In July 1849, Barlow Granger began the paper in an abandoned log cabin by the junction of the Des Moines and Raccoon River. In 1854, ''The Star'' became the ''Iowa Statesman'' which was also a Democratic paper. In 1857, ''The Statesman'' became the ''Iowa State Journal'', which published 3 times per week. In 1870, ''The Iowa Statesman'' became the ''Iowa State Leader'' as a Democratic newspaper, which competed with pro-Republican ''Iowa Daily State Register'' for the next 32 years. In 1902, George Roberts bought the ''Register'' and ''Leader'' and merged them into a morning newspaper. In 1903, Des Moines banker Gardner Cowles, Sr. purchased the ''Register and Leader''. The name finally became ''The Des Moines Register'' in 1915. (Cowles also acquired the ''Des Moines Tribune'' in 1908. The ''Tribune'', which merged with ...

Postdoctoral Researcher
A postdoctoral fellow, postdoctoral researcher, or simply postdoc, is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). The ultimate goal of a postdoctoral research position is to pursue additional research, training, or teaching in order to have better skills to pursue a career in academia, research, or any other field. Postdocs often, but not always, have a temporary academic appointment, sometimes in preparation for an academic faculty position. They continue their studies or carry out research and further increase expertise in a specialist subject, including integrating a team and acquiring novel skills and research methods. Postdoctoral research is often considered essential while advancing the scholarly mission of the host institution; it is expected to produce relevant publications in peer-reviewed academic journals or conferences. In some countries, postdoctoral research may lead to further formal qualificati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tantrum
A tantrum, temper tantrum, lash out, meltdown, fit or hissy fit is an emotional outburst, usually associated with those in emotional distress, that is typically characterized by stubbornness, crying, screaming, violence, defiance, angry ranting, a resistance to attempts at pacification, and, in some cases, hitting and other physically violent behavior. Physical control may be lost; the person may be unable to remain still; and even if the "goal" of the person is met, they may not be calmed. Throwing a temper tantrum can lead to a child getting detention or being suspended from school for older school age children. A tantrum may be expressed in a tirade: a protracted, angry speech. In early childhood Tantrums are one of the most common forms of problematic behavior in young children but tend to decrease in frequency and intensity as the child gets older. For a toddler, tantrums can be considered as normal, and even as gauges of developing strength of character. While tantru ...

CUSPEA
CUSPEA (China-U.S. Physics Examination and Application,李政道奖学金) was an examination and admission system used by the physics departments of some American and Canadian universities for graduate school admission from People's Republic of China between 1979 and 1989. It was created by the Chinese-American Nobel laureate in physics Professor Tsung-Dao Lee (诺贝尔物理学奖得主李政道教授) and Chinese physics community as an alternative graduate school admission procedure. At that time in China, higher education was still recovering from the Cultural Revolution; school transcripts and recommendation letters were difficult to evaluate. Furthermore, standardized tests such as the Graduate Record Examination were unavailable in China. Details The CUSPEA exam was in English and had a similar scope to that of Ph.D. written qualifying exams in major American universities. The questions were prepared by physics professors from participating North American universities ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
