What is Math?
      #3418299 - 10/29/09 01:29 PM

The other day I was talking to a college teacher of electrical engineering and he told me that he once asked a math teacher wath were the math teachers studying. The math teacher said "we study the competence of the human brain". I found that answer pretty good.

How would you define math?

A language of numbers rather than letters.

Until you get to higher maths, then it becomes a language of letters all over again!

Without consulting Wikipedia I'll take a shot.

Mathematics is a tool, just as language is a tool. It is a tool that can express real world things in unambiguous ways. Our language is useful for expressing certain things, but it's impossible to express how much money is in one's pocket without mathematics. It's impossible to explain Special or General Relativity without mathematics.

Math, in and of itself, is without purpose. It's how we use it that gives it usefulness. To put that another way, there are whole branches of math that explain nothing (at least nothing we know of) but can be logically derived from simple to complex mathematical concepts. Similarly, we can use language to express meaningless thoughts - some of my own posts come to mind - maybe this one.

In a nutshell, and how my engineer's mind understands it: Math is a language tool used to describe unambiguously real world phenomena.

To me math is a tool not unlike the other tools in my toolbox at work. Math just gets used more than the rest, and never wears out.

So math is an invention, not a discovery?

I'd say it's both. The particular symbolic language that we manipulate is invented, and many of the embellishments that we add to it are invented. But the underlying logic and numeracy, the basic algebraic properties and logical relationships, are discovered.

I always liked "the science of drawing necessary conclusions", which distinguishes it from logic, "the science of drawing any conclusions" - C.S. Pierce.

Something about the question is disturbing to me.

Math consist of three studies:
Arithmatic - the study of numbers
Geometry - the study of shapes
Analysis - the study of infinity

For many years this has been sufficient for me. I am unable to embrace the question.

Also

A system of language and rules which allow for the modeling of reality in abstraction.

The etymology of mathematics I find instructive. From the Greek word "mathemas" meaning learning, study or science (or, generally speaking, all three).

At its foundation, mathematics permits the study of our Universe.

Although the basics concepts were understood by extremely clever men three hundred years ago, the advent of computer technology gave Dr. Mandelbrot a bully pulpit from which to bring the concepts, and intriguing ramifications, of fractals into the mainstream.

Which begs the question: Arithmetic, Geometry, the Calculus have been around for a while. What have we overlooked? What's next?

It also allows you to model abstractions in the absence of reality.

I think the interesting question about math is whether it transcends human thought or not. Is it Something in the Universe which would exist whether Humans exist or not? Is it purely a human construction? Astronomers (and imagers especially) know that the size of image of an object photographed through a telescope is the object's angle (in radians, which is the "natural" measure of arc, not in degrees or grades which are arbitrary units) multiplied by the focal length of the telescope / objective. No adjusting variables. Have you ever been baffled by how extraordinarily simple that is?

I assert that the answer is yes. If we find another society of thinking creatures who have the ability to manipulate their environment I am confident that they will have counting numbers and identities that look like 1+1=2 and 1 * 1 = 1. If they are so different from us that they do not find it necessary to do this we may not recognize them as intelligent. It logically follows that they may feel the same way about us.

Have you considered that some societies may have adopted the number we call pi as 1. They may then consider the radius of a circle as an irrational number. It is the ratio between the two that I assert that they will know.

BTW, the degree is not exactly arbitrary. I understand that it size was chosen by the Babylonians because they did not like fractions. 360 is divisible by 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180 & 360. This unit was natural to them.
