What is the importance of 1 and 0?
The numbers zero and one are so ubiquitous (present everywhere)
in math and technology, that the question becomes, what are you
doing with them?
In computer science, one and zero are the alphabet of the most
primitive computer language, the language of off and on, or signal
and no signal. This makes zero and one utterly fundamental to
computer science.
In math, one is a unit, a very rare, very important type of
number. Zero, representing nothing, also has special importance.
Zero is linked to one by the successor function. Mathematicians
tend to judge the importance of things by their usefulness, and
zero and one are among the most used numbers in math, particularly
in discrete math.
In logic, zero and one can be associated with the truth values:
true and false. Zero and one are also the first two natural
numbers, the natural numbers being important for establishing the
idea of countability.
