51Contourite — A contourite is a sedimentary deposit produced by thermohaline induced deepwater bottom currents and may be influenced by wind or tidal forces.[1][2] Most contourites are formed in continental rise to lower slope settings, although they may occur …
52Spud gun — For the child s toy which fires small pieces of potato, see spud gun (toy). A pneumatic potato cannon A potato cannon (also known as a spud gun or spudzooka ) is a pipe based cannon which uses air pressure (pneumatic), Propellant, or… …
53Proper motion — The proper motion of a star is its angular change in position over time as seen from the center of mass of the solar system.[1] It is measured in seconds of arc per year, arcsec/yr, where 3600 arcseconds equal one degree.[2] This contrasts with… …
54Warp drive — is a form of faster than light propulsion in the fictional universe of Star Trek, capable of propelling spacecraft or objects to many multiples of the speed of light but avoiding the problems of time dilation. It is also featured in several… …
55Internal ballistics — Internal ballistics, a subfield of ballistics, is the study of a projectile s behavior from the time its propellant s igniter is initiated until it exits the gun barrel. The study of internal ballistics is important to designers and users of… …
56Explosive velocity — Explosive velocity, also known as detonation velocity or velocity of detonation (VoD), is the velocity at which the shock wave front travels through a detonated explosive. The data listed for a specific substance is usually a rough prediction… …
57Beeman's algorithm — is a method for numerically integrating ordinary differential equations, generally position and velocity, which is closely related to Verlet integration. It produces identical positions to Verlet, but is more accurate in velocities. It is most… …
58Relative velocity — In kinematics, relative velocity is the vector difference between the velocities of two objects, as evaluated in terms of a single coordinate system, usually an inertial frame of reference unless specifically stated otherwise.For example, if the… …
59Erosion corrosion of copper water tubes — Erosion corrosion, also known as impingement damage, is the combined effect of corrosion and erosion caused by rapid flowing turbulent water. It is probably the second most common cause of copper tube failures behind Type 1 pitting which is also… …
60.458 Lott — 458 Lott, its parent case the .375 H H Magnum and the .458 Winchester Magnum for comparison. Type Rifle …
