Mathematicians Of The Day

15th April



On this day in 1831 Gauss introduces the term "complex" for a + bi. Most of the 17th and 18th century writers spoke of a + bi as an imaginary quantity. Gauss saw the desirability of having different names for ai and a + bi, so he gave to the latter the Latin expression numeros integros complexos.

On this day in 2013 Google released an Euler doodle.

Quotation of the day

From Leonhard Euler
For since the fabric of the universe is most perfect and the work of a most wise creator, nothing at all takes place in the universe in which some rule of the maximum or minimum does not appear.
