Anti-de Sitter space bell. It might be described as being the "opposite" of the surface of a sphere, which has a positive curvature. General relativity is a theory of the nature of time, space and gravity in which gravity is a curvature of space and time that results from the presence of matter or energy. Energy and mass are equivalent (as expressed in the equation "E" = "mc"), and space and time can be translated into equivalent units based on the speed of light ("c" in the "E" = "mc" equation). A common analogy involves the way that a dip in a flat
Optic equation lens formula: Components of an electrical circuit or electronic circuit can be connected in what is called a series or parallel configuration. For example, the total resistance value "R" of two resistors with resistances "R" and "R" connected in "parallel" follows the optic equation: Similarly, the total inductance "L" of two inductors with inductances "L" and "L" connected in "parallel" is given by: and the total capacitance "C" of two capacitors with capacitances "C" and "C" connected in "series" is as follows: The optic equation of the crossed ladders problem can be applied to folding rectangular paper into three equal
