Is god a scalar or a vector

Selection of specialist mathematical topics

There are a few math topics to choose from. They can be helpful in understanding and solving formulas and equations that occur over and over again in the field of electronics.

Mathematics is the alphabet that God used to describe the universe.
(Galileo Galilei, Italian mathematician and philosopher, 1564 - 1642)
