Peace and conflict studiesPeace and conflict studies or conflict analysis and resolution is a social science field that identifies and analyzes violent and nonviolent behaviors as well as the structural mechanisms attending conflicts (including social conflicts), with a view towards understanding those processes which lead to a more desirable human condition. A variation on this, peace studies (irenology), is an interdisciplinary effort aiming at the prevention, de-escalation, and solution of conflicts by peaceful means, thereby seeking "victory" for all parties involved in the conflict.
Peace symbolsA number of peace symbols have been used many ways in various cultures and contexts. The dove and olive branch was used symbolically by early Christians and then eventually became a secular peace symbol, popularized by a Dove lithograph by Pablo Picasso after World War II. In the 1950s the "peace sign", as it is known today (also known as "peace and love"), was designed by Gerald Holtom as the logo for the British Campaign for Nuclear Disarmament (CND), a group at the forefront of the peace movement in the UK, and adopted by anti-war and counterculture activists in the US and elsewhere.
Force carrierIn quantum field theory, a force carrier (also known as a messenger particle, intermediate particle, or exchange particle) is a type of particle that gives rise to forces between other particles. These particles serve as the quanta of a particular kind of physical field. Wave–particle duality Quantum field theories describe nature in terms of fields. Each field has a complementary description as the set of particles of a particular type.
Fishing vesselA fishing vessel is a boat or ship used to catch fish in the sea, or on a lake or river. Many different kinds of vessels are used in commercial, artisanal and recreational fishing. It is difficult to estimate the number of recreational fishing boats. They range in size from small dinghies to large charter cruisers, and unlike commercial fishing vessels, are often not dedicated just to fishing. Prior to the 1950s there was little standardisation of fishing boats. Designs could vary between ports and boatyards.
Democratic peace theoryProponents of "democratic peace theory" argue that both liberal and republican forms of democracy are hesitant to engage in armed conflict with other identified democracies. Different advocates of this theory suggest that several factors are responsible for motivating peace between democratic states. Individual theorists maintain "monadic" forms of this theory (democracies are in general more peaceful in their international relations); "dyadic" forms of this theory (democracies do not go to war with other democracies); and "systemic" forms of this theory (more democratic states in the international system makes the international system more peaceful).
Particle acceleratorA particle accelerator is a machine that uses electromagnetic fields to propel charged particles to very high speeds and energies, and to contain them in well-defined beams. Large accelerators are used for fundamental research in particle physics. The largest accelerator currently active is the Large Hadron Collider (LHC) near Geneva, Switzerland, operated by the CERN. It is a collider accelerator, which can accelerate two beams of protons to an energy of 6.5 TeV and cause them to collide head-on, creating center-of-mass energies of 13 TeV.
Survey vesselA survey vessel is any type of ship or boat that is used for underwater surveys, usually to collect data for mapping or planning underwater construction or mineral extraction. It is a type of research vessel, and may be designed for the purpose, modified for the purpose or temporarily put into the service as a vessel of opportunity, and may be crewed, remotely operated, or autonomous. The size and equipment vary to suit the task and availability.
SmokeSmoke is a suspension of airborne particulates and gases emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass. It is commonly an unwanted by-product of fires (including stoves, candles, internal combustion engines, oil lamps, and fireplaces), but may also be used for pest control (fumigation), communication (smoke signals), defensive and offensive capabilities in the military (smoke screen), cooking, or smoking (tobacco, cannabis, etc.
Peace churchesPeace churches are Christian churches, groups or communities advocating Christian pacifism or Biblical nonresistance. The term historic peace churches refers specifically only to three church groups among pacifist churches: Church of the Brethren, including all daughter churches such as the Old German Baptist Brethren, Old Brethren and Dunkard Brethren; Religious Society of Friends (Quakers); and Mennonites, including the Amish, Beachy Amish, Old Order Mennonites, and Conservative Mennonites In addition to the Schwarzenau Brethren and Mennonites, other Anabaptist Christian fellowships, such as the Hutterian Brethren, River Brethren, Apostolic Christian Church and Bruderhof teach pacifism as well.
Charged particle beamA charged particle beam is a spatially localized group of electrically charged particles that have approximately the same position, kinetic energy (resulting in the same velocity), and direction. The kinetic energies of the particles are much larger than the energies of particles at ambient temperature. The high energy and directionality of charged particle beams make them useful for many applications in particle physics (see Particle beam#Applications and Electron-beam technology).
