Matter



Matter is the substance of which a physical object is composed. In physics, it is everything that is constituted of elementary particles fermions. All gauge bosons (of which the photon is one), which mediate the four fundamental forces, are thus not considered matter, even though they certainly have energy and some also mass. Matter thus consists of quarks and leptons. Quarks combine to form hadrons, primarily baryons and mesons, through the strong interaction and are actually thought to be always thus confinement problem. Among the baryons are the proton and the neutron which further combine to form the nucleus of all chemical elements of the periodic table. Usually these nuclei are surrounded by a cloud of electrons. A nucleus with as many electrons as protons, which is thus electrically neutral, is called an atom, otherwise it is an ion. Chemistry is the science that studies how nuclei and electrons combine to form chemical compounds. In bulk, matter can be in several different phases of matters, according to particle density and energy density or alternatively pressure and temperature, such as Bose-Einstein condensated, superfluidic, liquid, fluidic, gaseous, solid and plasma. As circumstances change, matter may change from one phase to another. This phenomenon is called phase transition and is studied in the field of thermodynamics. In small quantities matter can exhibit properties which are entirely different from those of the bulk material. ==See also== *Antimatter *Phases of matter *Particle physics, which provides a bit of historical background ---- Matter, in the sense of content, is also used in contrast to form.

"...MATTER AND ENERGY WERE FUNDAMENTALLY SEPARATE TYPES OF MATERIAL." EINSTEIN "SHOWED THAT MASS AND ENERGY WERE INTERCHANGABLE." THERE IS AN IMPLICATION THAT MATTER AND MASS ARE THE SAME. THIS IS CONFUSING AND NEEDS CORRECTING AND EXPLAINING. This sentence "Matter can more accurately be defined as the energy that has a low vibratory rate, a compressed energy state." is very confusing. Matter is made of protons, neutrons and electrons and these all have very HIGH vibratory rates (Compton frequencies of approx 10^20 to 10^23 Hz). Why does it state "LOW" vibratory rate? It would be more accurate to state that matter is energy travelling at velocity less than c. This article needs a lot of cleaning up! User:Dpr 22:12, 5 Mar 2005 (UTC) I gotta agree with Dpr. "(among which the photon)"... what? ==What is Matter== If you take a look ar physics it is all that is studied by physics. But are fotons matter? I'm not sure. Fotons are: massless, (gauge) bosons. Gravitons and gluons are also massless, but gluons are definately matter. The W and Z gauge bosons are massive, are they thus matter?User:MarSch 14:40, 18 Mar 2005 (UTC) :it seams that matter fields in QFT are all fermion fields and that the bosonic interaction fields are not matter even though they may have mass. Thus weak vector bosons, which acquire mass through Higgs, would not be considered matter. User:MarSch 12:23, 6 Apr 2005 (UTC) >> Matter, in the sense of content, is also used in contrast to form. I love this sentence! It is cryptic, yet at the same time, concise and exact. -c neg
