... with natural numbers, so we must first convert characters into numbers: this is easily done using (for example) the ASCII format which represents characters by 7-bit numbers. Then, for example, by concatenating (that is joining together) the 7 bit codes of 8 characters we would produce a 56-bit (7 b ...

... Miller indices - A shorthand notation to describe certain crystallographic directions and planes in a material. Distance is measured in terms of lattice parameters along x, y and z coordinates using right-hand coordinate system. Planes – Crystallographic planes are denoted by first ( ) brackets. ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
