Ray casting is a technique in which the surfaces of objects observable to the camera are found by throwing or casting the rays of light from viewer to the scene. The main idea behind the ray casting is to shoot rays from the eye, one per pixel, and find out the closest object which block the path of that ray – imagine of an image as a screen door, with each and every square in the screen being a pixel.
Lagrange points: The points in the vicinity of two massive bodies (like the Earth and Moon) with each others' relevant gravities balance. There are five, labeled L1 via L5. L1, L2, and L3 lie all along the centerline among the centers
Loschmidt constant: Loschmidt number: NL: The total number of particles per unit volume of an ideal gas at standard pressure and temperature. It has the value of 2.687 19 x 1025 m-3.
Eddington limit (Sir A. Eddington): The hypothetical limit at which the photon pressure would surpass the gravitational attraction of a light-emitting body. That is, a body emanating radiation at bigger than the Eddington limit would
Heat pumps move heat from one place to another. They work similar to refrigeration. The movement of heat takes energy, either electrical energy as in the use of vapor compression heat pumps or thermal energy as in the use of absorption heat pump
