//__ **The Moore-Penrose Pseudo Inverse** __//

"Moore and Penrose showed that there is a general solution to these equations of the form ~y = A †  ~b . The matrix A  †  is the Moore-Penrose “pseudo-inverse,” and they proved that this matrix is the unique matrix that satisfies the following properties": 1. A A †  A = A  2. A  †  A A  †  = A  † 3. ( A A †  )  T  = A A  † 4. ( A †  A )  T  = A  †  A

__**The Twistor Theory**__

A mathematical theory, which maps the geometric objects of the four dimensional space-time into the geometric objects in the 4-dimensional complex space with the metric signature. The coordinates in such a space are called "twistors." For more information please see [|Twistor Theory transperacy]




 * __ Terrell-Penrose effect __**

Terrell rotation is the distortion that a passing object would appear to undergo, according to the special theory of relativity if it were travelling a significant fraction of the speed of light.
