Physics print that page


Physics is one of the oldest academic disciplines , perhaps the oldest through its inclusion of astronomy . [ 6 ] Over the last two millennia, physics was a part of natural philosophy along with chemistry , certain branches of mathematics , and biology , but during the Scientific Revolution

Spin (physics) print that page

In quantum mechanics and particle physics , spin is a fundamental characteristic property of elementary particles , composite particles ( hadrons ), and atomic nuclei . [ note 1 ] All elementary particles of a given kind have the same spin quantum number , an important part of a particle

History of physics print that page


As forms of science historically developed out of philosophy , physics (from Greek : φύσις physis " nature ") was originally referred to as natural philosophy , a term describing a field of study concerned with "the workings of nature". Contents 1 Early history 2 Galileo

Moscow Institute of Physics and Technology print that page


Kapitsa argued for the need for such a school, which he tentatively called the Moscow Institute of Physics and Technology , to better maintain and develop the country's defense potential. The institute would follow the principles outlined above, and was supposed to be governed by a board of

Physics engine print that page


These are four examples of a physics engine simulating an object falling onto a slope. The examples differ in accuracy of the simulation: No physics . Gravity , no collision detection. Gravity and collision detection , no rigid body dynamics. Gravity, collision detection and rotation

Particle physics print that page


Modern particle physics research is focused on subatomic particles , including atomic constituents such as electrons , protons , and neutrons (protons and neutrons are actually composite particles called baryons , made of quarks ), particles produced by radioactive and scattering processes

Causality (physics) print that page

equal probability of stopping at each position. [ edit ] Various concepts of cause and effect in physics In physics it is useful to interpret certain terms of a physical theory as causes and other terms as effects. Thus, in classical (Newtonian) mechanics a cause may be represented by

Drag (physics) print that page


In fluid dynamics , drag (sometimes called air resistance or fluid resistance ) refers to forces that oppose the relative motion of an object through a fluid (a liquid or gas ). Drag forces act in a direction opposite to the oncoming flow velocity . [ 1 ] Unlike other resistive forces

Plasma (physics) print that page


In physics and chemistry , plasma is a state of matter similar to gas in which a certain portion of the particles are ionized . Heating a gas may ionize (reduce the number of electrons in) its molecules or atoms, thus turning it into a plasma, which contains charged particles: positive

Digital physics print that page

In physics and cosmology , digital physics is a collection of theoretical perspectives based on the premise that the universe is, at heart, describable by information , and is therefore computable . Therefore, the universe can be conceived as either the output of a computer program or
