Zero

Zero NumberIs zero a number? Two ways to answer this one, the simple answer and the complicated mathematical answer.

The simple answer: Yes, zero is a number but you are not alone if you wonder why. Indian mathematicians first came up with the number idea around 650 AD. Originally, perhaps as early as 200 AD, they used zero as a placeholder in another number. For example, in our notation: 216 is a different number than 2016. This use of zero advanced trade, commerce, and bookkeeping but does not qualify zero as a number. Zero, in its place-keeping function, is a kind of punctuation mark to help us interpret numbers correctly[1].

The mathematical answer: Zero is clearly an element of the set of Real Numbers, it’s the “additive identity” — the number that, when added to any other number x, doesn’t change the value of x. (Similarly, 1 is the multiplicative identity — the number that, when multiplied by any other number x, doesn’t change the value of x.) Thus, zero is a number, just as any other element of the set of Real Numbers is a number.

But before you get to the Real Numbers, you probably start with the Counting Numbers or Natural Numbers, the set N = {1, 2, 3, …} in set notation. Zero isn’t a member of the set of Natural Numbers since you normally don’t start counting with zero. A primitive society developing a counting system wouldn’t think of “none” … they’d start counting with “one.” Thus, if by “number” you mean “the set of all Natural Numbers,” then zero isn’t among them. Of course, the concept of zero makes its appearance pretty early historically (the idea of using zero as a placeholder digit comes later, but that’s notational, and a different story)[2].

What is math?

Math

Mathematics is the art and science of abstraction; it is the systematic study of quantity, structure, space, and change; to paraphrase Newton, it is the language in which the universe is written. The study of mathematics provides the abilities to analyze data, discover patterns, and reason logically[1]. Mathematics (from Greek μάθημα (máthēma) — knowledge, study, learning) is the study of quantitystructurespace, and change[2].

other definition about math, you can see below:

math·e·mat·ics n. (used with a sing. verb). The study of the measurement, properties, and relationships of quantities, using numbers and symbols. [From Middle English mathematik, from Old French mathematique, from Latin mathematica, from Greek mathematike (tekhne)]

The American Heritage Dictionary


math-e-mat-ics n. … the science of numbers and their operations, interrelations, combinations, generalizations, and abstractions and of space configurations and their structure, measurement, transformations, and generalizations.

Webster’s New Collegiate Dictionary


Mathematics is a language.

Gibbs, Josiah Willard. 1839-1903.
American mathematician and physicist.


To those who do not know Mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty of nature. … If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in.

Richard Feynman. 1918-1988.
American physicist.
The Character of Physical Law


Mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true.

Bertrand Russell. 1872–1970
British philosopher, mathematician.
Mysticism and Logic


All science requires Mathematics. The knowledge of mathematical things is almost innate in us… This is the easiest of sciences, a fact which is obvious in that no one’s brain rejects it; for laymen and people who are utterly illiterate know how to count and reckon.

Roger Bacon. 1214-1294
English philosopher, scientist.
Opus Maius

What is mathematics?   Most people would say it has something to do with numbers, but numbers are just one type of mathematical structure.   Saying “math is the study of numbers” (or something similar) is like saying that “zoology is the study of giraffes”.  Math may be better thought of as the study of patterns, but this too falls short…

The more I study math, the more I wonder about what exactly math is.  Actually nobody knows.   It seems to be a product or our minds, and yet reflects the external universe with uncanny accuracy.   A mathematician develops a mathematical theory for its aesthetic unworldly beauty and it’s compelling evolution, with no thought of how it might be applied to the world.    A century later a physicist finds this theory to be perfect to use as a framework to express his physics (this sort of thing happens frequently).   Pretty weird how intimately connected our innermost “mind” and the outermost “universe” really are.   This is a profound mystery!

Bruce Bennett, my advisor in grad school, defines mathematics as “unified consciousness theory”.   As you come to master a branch of mathematics, it’s as though you’ve grown a new abstract organ of perception through which you may then view the world.  You’ve grown a new “mind’s eye” that can perceive realities literally inconceivable without this new organ of perception.
