Isochoric process

In thermodynamics, an isochoric process, also called a constant-volume process, an isovolumetric process, or an isometric process, is a thermodynamic process during which the volume of the closed system undergoing such a process remains constant. An isochoric process is exemplified by the heating or the cooling of the contents of a sealed, inelastic container: The thermodynamic process is the addition or removal of heat; the isolation of the contents of the container establishes the closed system; and the inability of the container to deform imposes the constant-volume condition. The isochoric process here should be a quasi-static process.

Tunnel vision (metaphor)

Tunnel vision (marksmanship)

Tunnel vision is a term used when a shooter is focused on a target, and thus misses what goes on around that target. Therefore an innocent bystander may pass in front or behind of the target and be shot accidentally. This is easily understandable if the

Acoustic lubrication

Acoustic or sonic lubrication occurs when sound permits vibration to introduce separation between the sliding faces. This could happen between two plates or between a series of particles. The frequency of sound required to induce optimal vibration, and

Fundamental theorem of topos theory

In mathematics, The fundamental theorem of topos theory states that the slice of a topos over any one of its objects is itself a topos. Moreover, if there is a morphism in then there is a functor which preserves exponentials and the subobject

Envelope (motion)

In mechanical engineering, an envelope is a solid representing all positions which may be occupied by an object during its normal range of motion

Inconsistent comparison

An inconsistent comparison is a misleading argument popular in advertising. For example, an advertisement might say "product X is less expensive than product A, has better quality than product B, and has more features than product C". This is designed to
