  1. Physics - Wikipedia › wiki › Physics

    Physics (from Ancient Greek: φυσική (ἐπιστήμη), romanized: physikḗ (epistḗmē), lit. 'knowledge of nature', from φύσις phýsis 'nature') is the natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force.

  2. Physics - Simple English Wikipedia, the free encyclopedia › wiki › Physics

    Physics is a branch of science. It is one of the most fundamental scientific disciplines. The main goal of physics is to explain how things move in space and time and understand how the universe behaves. It studies matter, forces and their effects. The word physics comes from the Greek word ἡ φύσις, meaning "nature".

  3. Outline of physics - Wikipedia › wiki › Outline_of_physics

    Physics – branch of science that studies matter and its motion through space and time, along with related concepts such as energy and force. Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. According to physics, the physical ...

    Physics is a scientific discipline that seeks to construct and experimentally test theories of the physical universe. These theories vary in their scope and can be organized into several distinct branches, which are outlined in this article. Domains of major fields of physics

    Classical mechanics is a model of the physics of forces acting upon bodies; includes sub-fields to describe the behaviors of solids, gases, and fluids. It is often referred to as "Newtonian mechanics" after Isaac Newton and his laws of motion. It also includes the classical approach as given by Hamiltonian and Lagrange methods. It deals with the motion of particles and general system of particles.

    The first chapter of The Feynman Lectures on Physics is about the existence of atoms, which Feynman considered to be the most compact statement of physics, from which science could easily result even if all other knowledge was lost. By modeling matter as collections of hard spheres, it is possible to describe the kinetic theory of gases, upon which classical thermodynamics is based.

    The study of the behaviors of electrons, electric media, magnets, magnetic fields, and general interactions of light.

    The special theory of relativity enjoys a relationship with electromagnetism and mechanics; that is, the principle of relativity and the principle of stationary action in mechanics can be used to derive Maxwell's equations, and vice versa.

    Quantum mechanics is the branch of physics treating atomic and subatomic systems and their interaction based on the observation that all forms of energy are released in discrete units or bundles called "quanta". Remarkably, quantum theory typically permits only probable or statistical calculation of the observed features of subatomic particles, understood in terms of wave functions. The Schrödinger equation plays the role in quantum mechanics that Newton's laws and conservation of energy ...

    The Physics is a named text, written in ancient Greek, collated from a collection of surviving manuscripts known as the Corpus Aristotelicum, attributed to the 4th-century BC philosopher Aristotle. First page of text, Volume 2, of a work less formally known as "the Oxford Aristotle", with the usual label Ex Recensione Immanuelis Bekkeri appended to the title. The translation of ex is equivocal in English; it could mean "of" or "from", not helpful in this case. The image is not the original publi

    It is a collection of treatises or lessons that deal with the most general principles of natural or moving things, both living and non-living, rather than physical theories or investigations of the particular contents of the universe. The chief purpose of the work is to discover the principles and causes of change, or movement, or motion, especially that of natural wholes. In the conventional Andronicean ordering of Aristotle's works, it stands at the head of, as well as being foundational to, t

    The Physics is composed of eight books, which are further divided into chapters. This system is of ancient origin, now obscure. In modern languages, books are referenced with Roman numerals, standing for ancient Greek capital letters. Chapters are identified by Arabic numerals, but the use of the English word "chapter" is strictly conventional. Ancient "chapters" are generally very short, often less than a page. Additionally, the Bekker numbers give the page and column used in the Prussian Acade

    The works of Aristotle are typically considered foundational to Western science and philosophy. The citations below are not given as any sort of final modern judgement on the interpretation and significance of Aristotle, but are only the notable views of some moderns.

    The first Nobel Prize in Physics was awarded in 1901 to Wilhelm Conrad Röntgen, of Germany, who received 150,782 SEK, which is equal to 7,731,004 SEK in December 2007. John Bardeen is the only laureate to win the prize twice—in 1956 and 1972. Marie Skłodowska-Curie also won two Nobel Prizes, for physics in 1903 and chemistry in 1911.
