The isopleth crosses the scale for T at just under 4.65. A nomogram (from Greek nomos νόμος, "law" and grammē γραμμή, "line"), also called a nomograph, alignment chart, or abac, is a graphical calculating device, a two-dimensional diagram designed to allow the approximate graphical computation of a mathematical function.
Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at and below the scale of atoms. [2] : 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science . Quantum mechanics can describe many systems that ...
Graphical projection. In mathematics, a stereographic projection is a perspective projection of the sphere, through a specific point on the sphere (the pole or center of projection ), onto a plane (the projection plane) perpendicular to the diameter through the point.
Heisler charts permit evaluation of the central temperature for transient heat conduction through an infinitely long plane wall of thickness 2L, an infinitely long cylinder of radius r o, and a sphere of radius r o. Each aforementioned geometry can be analyzed by three charts which show the midplane temperature, temperature distribution, and ...
Prism graphs are examples of generalized Petersen graphs, with parameters GP ( n ,1). They may also be constructed as the Cartesian product of a cycle graph with a single edge. [1] As with many vertex-transitive graphs, the prism graphs may also be constructed as Cayley graphs. The order- n dihedral group is the group of symmetries of a regular ...
In photography, reciprocity refers to the relationship whereby the total light energy – proportional to the total exposure, the product of the light intensity and exposure time, controlled by aperture and shutter speed, respectively – determines the effect of the light on the film. That is, an increase of brightness by a certain factor is ...
A Nicol prism is a type of polarizer. It is an optical device made from calcite crystal used to convert ordinary light into plane polarized light . It is made in such a way that it eliminates one of the rays by total internal reflection , i.e. the ordinary ray is eliminated and only the extraordinary ray is transmitted through the prism .
In its most basic form, a moment is the product of the distance to a point, raised to a power, and a physical quantity (such as force or electrical charge) at that point: where is the physical quantity such as a force applied at a point, or a point charge, or a point mass, etc. If the quantity is not concentrated solely at a single point, the ...
