Clifford V. Johnson
Clifford Victor Johnson (born 5 March 1968) is a British theoretical physicist and professor at the University of California, Santa Barbara department of Physics. Biography Johnson was born in London, England, and lived in Montserrat for 10 years. From an early age, Johnson was interested in electronics. He would spend time reading on the subject, and designing small machinery such as radios. He graduated with a Bachelor of Science in Physics from Imperial College London in 1989 and he completed his Doctor of Philosophy in Mathematics and Physics from the University of Southampton in 1992. Johnson's research focus is in superstring theory and particle physics, specifically related to strongly coupled phenomena. He has previously worked at the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara, the Institute for Advanced Study, Durham University and Princeton University as a postdoctoral fellow. He worked as an assistant professor at the Unive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theoretical Physics
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict List of natural phenomena, natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena. The advancement of science generally depends on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigour while giving little weight to experiments and observations.There is some debate as to whether or not theoretical physics uses mathematics to build intuition and illustrativeness to extract physical insight (especially when normal experience fails), rather than as a tool in formalizing theories. This links to the question of it using mathematics in a less formally rigorous, and more intuitive or heuristic way than, say, mathematical physics. For example, while developing special relativity, Albert E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantum Gravity
Quantum gravity (QG) is a field of theoretical physics that seeks to describe gravity according to the principles of quantum mechanics. It deals with environments in which neither gravitational nor quantum effects can be ignored, such as in the vicinity of black holes or similar compact astrophysical objects, as well as in the early stages of the universe moments after the Big Bang. Three of the four fundamental forces of nature are described within the framework of quantum mechanics and quantum field theory: the Electromagnetism, electromagnetic interaction, the Strong interaction, strong force, and the Weak interaction, weak force; this leaves gravity as the only interaction that has not been fully accommodated. The current understanding of gravity is based on Albert Einstein's general theory of relativity, which incorporates his theory of special relativity and deeply modifies the understanding of concepts like time and space. Although general relativity is highly regarded for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cameo Appearance
A cameo appearance, also called a cameo role and often shortened to just cameo (), is a brief guest appearance of a well-known person or character in a work of the performing arts. These roles are generally small, many of them non-speaking ones, and are commonly either appearances in a work in which they hold some special significance (such as actors from an original movie appearing in its remake) or renowned people making uncredited appearances. Short appearances by celebrities, film directors, politicians, athletes or musicians are common. A crew member of the movie or show playing a minor role can be referred to as a cameo role as well, such as director Alfred Hitchcock who made frequent cameo appearances in his films. Concept Originally, in the 1920s, a "cameo role" meant "a small character part that stands out from the other minor parts". The ''Oxford English Dictionary'' connects this with the meaning "a short literary sketch or portrait", which is based on the lite ...

Science Fiction
Science fiction (often shortened to sci-fi or abbreviated SF) is a genre of speculative fiction that deals with imaginative and futuristic concepts. These concepts may include information technology and robotics, biological manipulations, space exploration, time travel, Parallel universes in fiction, parallel universes, and extraterrestrials in fiction, extraterrestrial life. The genre often explores human responses to the consequences of projected or imagined scientific advances. Science fiction is related to fantasy (together abbreviated wikt:SF&F, SF&F), Horror fiction, horror, and superhero fiction, and it contains many #Subgenres, subgenres. The genre's precise Definitions of science fiction, definition has long been disputed among authors, critics, scholars, and readers.

Discovery Channel
Discovery Channel, known as The Discovery Channel from 1985 to 1995, and often referred to as simply Discovery, is an American cable channel that is best known for its ongoing reality television shows and promotion of pseudoscience. It initially provided documentary television programming focused primarily on popular science, technology, and history, but by the 2010s had become increasingly dominated by programs that were reality television shows, promoted conspiracy theories, or advocated junk science.

History (U
History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives of several sources to devel ...

Physics Outreach
Physics outreach encompasses facets of science outreach and physics education, and a variety of activities by schools, research institutes, universities, clubs and institutions such as science museums aimed at broadening the audience for and awareness and understanding of physics. While the general public may sometimes be the focus of such activities, physics outreach often centers on developing and providing resources and making presentations to students, educators in other disciplines, and in some cases researchers within different areas of physics. History Ongoing efforts to expand the understanding of physics to a wider audience have been undertaken by individuals and institutions since the early 19th century. Historic works, such as the '' Dialogue Concerning the Two Chief World Systems'', and Two New Sciences by Galileo Galilei, sought to present revolutionary knowledge in astronomy, frames of reference, and kinematics in a manner that a general audience could understand ...

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. It 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. It is a member society of the American Institute of Physics. Since January 2021, it is 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 APS was to hold scientific m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
