Electric field - Wikipedia, the free encyclopedia The electric field or electric field intensity is a vector quantity, and the electric field strength is the magnitude of this vector. Electric fields exist around all charges; the direction of field lines at a point is defined by the direction of the electric force exerted on a positive test charge placed at that point. In physics, an electric field or E-field is an effect produced by an electric charge (or a time-varying magnetic field) that exerts a force on charged objects in the field. en.wikipedia.org /wiki/Electric_field   (1168 words)

Oil field - Wikipedia, the free encyclopedia Because an oil field may be remote from civilization, establishing a field is often an extremely complicated exercise in logistics. Thus, the typical oil field resembles a small self-contained city in the midst of a landscape dotted with drilling rigs and/or the pump jacks known as "nodding donkeys" because of their bobbing arm. In the modern age, the location and proven oil reserves of oil fields are a key underlying factor in many geopolitical conflicts. en.wikipedia.org /wiki/Oil_field   (789 words)

Somebody Else's Problem field - Wikipedia, the free encyclopedia An SEP field can be erected on, or projected around a bizarre and unbelievable scene so that the unconscious minds of the observers instantly abdicate responsibility for its existence, assert that it's "somebody else's problem", and therefore don't perceive it at all. The SEP field is a fictional technology from the Hitchhiker's Guide to the Galaxy "trilogy" by Douglas Adams. It is a cheaper alternative to an invisibility field. en.wikipedia.org /wiki/SEP_field   (208 words)

Field goal - Wikipedia, the free encyclopedia A field goal or dropped goal (usually abbreviated to "drop goal" in speech) is scored by drop kicking the ball above the crossbar and between the uprights. A field goal (formerly "goal from the field") is a general term used in some sports wherein a goal may be scored either during general play ("from the field") or via some sort of free shot. A dropped goal is worth three points in rugby union and one point in rugby league (in league, more commonly known as a field goal); conversions are worth two points in both codes. en.wikipedia.org /wiki/Field_goal   (2006 words)

Electromagnetism - Wikipedia, the free encyclopedia Electromagnetism is the physics of the electromagnetic field: a field, encompassing all of space, which exerts a force on those particles that possess the property of electric charge, and is in turn affected by the presence and motion of such particles. A non-zero electric field is produced by the presence of electrically charged particles, and gives rise to the electric force; this is the force that causes static electricity and drives the flow of electric charge (electric current) in electrical conductors. In classical electromagnetism, the electromagnetic field obeys a set of equations known as Maxwell's equations, and the electromagnetic force is given by the Lorentz force law. en.wikipedia.org /wiki/Electromagnetism   (1172 words)

Unified field theory - Wikipedia, the free encyclopedia His quest proved elusive and a unified field theory, sometimes grandiosely referred to as the Theory of Everything (TOE, for short), has remained the holy grail for physicists, the long-sought theory which would explain the nature and behavior of all matter. Given the requirements of a successful unified field theory, that it must explain all previous known results in a single framework while making new and falsifiable predictions, it is no surprise that this is a difficult task. They demonstrated that the gauge field from the weak interaction was structurally identical to the electromagnetic field. en.wikipedia.org /wiki/Unified_field_theory   (5205 words)

Stasis (fiction) - Wikipedia, the free encyclopedia A stasis field is a region where a stasis process is in effect.
