Physics
Physics is the scientific study of matter, its Elementary particle, 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." It is one of the most fundamental scientific disciplines. "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 physics. (...) You will come to see physics as a towering achievement of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Exxon
Exxon Mobil Corporation ( ) is an American multinational oil and gas corporation headquartered in Spring, Texas, a suburb of Houston. Founded as the largest direct successor of John D. Rockefeller's Standard Oil, the modern company was formed in 1999 following the merger of Exxon and Mobil. It is vertically integrated across the entire oil and gas industry, as well as within its chemicals division, which produces plastic, synthetic rubber, and other chemical products. As the largest U.S.-based oil and gas company, ExxonMobil is the seventh-largest company by revenue in the U.S. and 13th-largest in the world. It is the largest investor-owned oil company in the world. Approximately 55.56% of the company's shares are held by institutions, the largest of which as of 2019 were The Vanguard Group (8.15%), BlackRock (6.61%), and State Street Corporation (4.83%).

Purpose: Because living persons may suffer personal harm from inappropriate information, we should watch their articles carefully. By adding an article to this category, it marks them with a notice about sources whenever someone tries to edit them, to remind them of WP:BLP (biographies of living persons) policy that these articles must maintain a neutral point of view, maintain factual accuracy, and be properly sourced. Recent changes to these articles are listed on Special:RecentChangesLinked/Living people. Organization: This category should not be sub-categorized. Entries are generally sorted by family name In many societies, a surname, family name, or last name is the mostly hereditary portion of one's personal name that indicates one's family. It is typically combined with a given name to form the full name of a person, although several give ....

Year Of Birth Missing (living People)
A year is a unit of time based on how long it takes the Earth to orbit the Sun. In scientific use, the tropical year (approximately 365 solar days, 5 hours, 48 minutes, 45 seconds) and the sidereal year (about 20 minutes longer) are more exact. The modern calendar year, as reckoned according to the Gregorian calendar, approximates the tropical year by using a system of leap years. The term 'year' is also used to indicate other periods of roughly similar duration, such as the lunar year (a roughly 354-day cycle of twelve of the Moon's phasessee lunar calendar), as well as periods loosely associated with the calendar or astronomical year, such as the seasonal year, the fiscal year, the academic year, etc. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Statistical Mechanics And Its Applications
Statistics (from German: ', "description of a state, a country") is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied. Populations can be diverse groups of people or objects such as "all people living in a country" or "every atom composing a crystal". Statistics deals with every aspect of data, including the planning of data collection in terms of the design of surveys and experiments. When census data (comprising every member of the target population) cannot be collected, statisticians collect data by developing specific experiment designs and survey samples. Representative sampling assures that inferences and conclusions can reasonably extend from the sample to the population as a whole. An experimental study involves taking measurements of the syst ...

National Science Foundation CAREER Awards
The National Science Foundation CAREER award is the most prestigious award presented by the National Science Foundation (NSF) of the United States Federal Government to support junior faculty who exemplify the role of teacher-scholars through research and education, and the integration of these endeavors in the context of their organizations' missions. The awards, presented once each year, include a federal grant of minimum $400,000 for research and education activities for five-year period. On 30 May 2025, the Trump administration requested a budget that eliminated the CAREER award. History The Presidential Young Investigators (PYI) program was initiated in 1983 during the presidency of Ronald Reagan, and remained active until the NSF New Young Investigators (NYI) program replaced it in 1992. Both programs were research-oriented and funded an average of 200 faculty members per year. Another, more selective program began in 1992, when the White House asked NSF to institute the ...

Herbert Newby McCoy
Herbert Newby McCoy (June 29, 1870, Richmond, Indiana – May 7, 1945, Los Angeles, California) was an American chemist who taught at the University of Chicago and the University of Utah and was the vice-president of Lindsay Light & Chemical Company. He contributed numerous papers on physical chemistry, radioactivity and rare earths. McCoy and his wife-to-be, chemist Ethel Mary Terry, wrote the three-volume set ''Introduction to General Chemistry'' (1919), ''Laboratory outline of General Chemistry'' (1920) and ''Teachers Manual and Notes'' (1920). Background McCoy was born in Richmond, Indiana, on June 29, 1870. His father died when he was young, leaving him to earn his own education.

H-index
The ''h''-index is an author-level metric that measures both the productivity and citation impact of the publications, initially used for an individual scientist or scholar. The ''h''-index correlates with success indicators such as winning the Nobel Prize, being accepted for research fellowships and holding positions at top universities. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications. The index has more recently been applied to the productivity and impact of a scholarly journal as well as a group of scientists, such as a department or university or country. The index was suggested in 2005 by Jorge E. Hirsch, a physicist at UC San Diego, as a tool for determining theoretical physicists' relative quality and is sometimes called the Hirsch index or Hirsch number. Hirsch intended the ''h''-index to address the main disadvantages of other bibliometric indicators. The total number of ...
