I challenge the student of mathematics

 

It appears to me that most people look on math as something with supernatural qualities. I challenge the student of math to develop and post short essays on Internet discussion forums about those fundamental aspects of math that you think people can and should comprehend.

 

What follows is something that I have posted regarding my idea of what ordinary citizens should know abut this very fundamental domain of knowledge.

 

Arithmetic is object collection

 

It is a hypothesis of SGCS (Second Generation Cognitive Science) that the sensorimotor activity of collecting objects by a child constitute a conceptual metaphor at the neural level leading to a primary metaphor that ‘arithmetic is object collection’. The arithmetic teacher attempting to teach the child at a later time depends upon this already accumulated knowledge. Of course, all of this is known to the child without the symbolization or the conscious awareness of the child.

 

The pile of objects became ‘bigger’ when the child added more objects and became ‘smaller’ when objects were removed. The child easily recognizes while being taught arithmetic that 5 is bigger than 3 and 3 is littler than 7. The child knows many entailments, many ‘truths’, resulting from playing with objects. The teacher has little difficulty convincing the child that two collections A and B are increased when another collection C is added, or that if A is bigger than B then A+C is bigger than B+C.

 

At birth an infant has a minimal innate arithmetic ability. This ability to add and subtract small numbers is called subitizing. (I am speaking of a cardinal number—a number that specifies how many objects there are in a collection, don’t confuse this with numeral—a symbol). Many animals display this subitizing ability.

 

In addition to subitizing the child, while playing with objects, develops other cognitive capacities such as grouping, ordering, pairing, memory, exhaustion-detection, cardinal-number assignment, and independent order.

 

Subitizing ability is limited to quantities 1 to 4. As a child grows s/he learns to count beyond 4 objects. This capacity is dependent upon 1) Combinatorial-grouping—a cognitive mechanism that allows you to put together perceived or imagined groups to form larger groups. 2) Symbolizing capacity—capacity to associate physical symbols or words with numbers (quantities).

 

“Metaphorizing capacity: You need to be able to conceptualize cardinal numbers and arithmetic operations in terms of your experience of various kinds—experiences with groups of objects, with the part-whole structure of objects, with distances, with movement and location, and so on.”

 

“Conceptual-blending capacity. You need to be able to form correspondences across conceptual domains (e.g., combining subitizing with counting) and put together different conceptual metaphors to form complex metaphors.”

 

Primary metaphors function somewhat like atoms that can be joined into molecules and these into a compound neural network. On the back cover of “Where Mathematics Comes From” is written “In this acclaimed study of cognitive science of mathematical ideas, renowned linguist George Lakoff pairs with psychologist Rafael Nunez to offer a new understanding of how we conceive and understand mathematical concepts.”

 

“Abstract ideas, for the most part, arise via conceptual metaphor—a cognitive mechanism that derives abstract thinking from the way we function in the everyday physical world. Conceptual metaphor plays a central and defining role in the formation of mathematical ideas within the cognitive unconscious—from arithmetic and algebra to sets and logic to infinity in all of its forms. The brains mathematics is mathematics, the only mathematics we know or can know.”

 

We are acculturated to recognize that a useful life is a life with purpose. The complex metaphor ‘A Purposeful Life Is a Journey’ is constructed from primary metaphors: ‘purpose is destination’ and ‘action is motion’; and a cultural belief that ‘people should have a purpose’.

 

A Purposeful Life Is A Journey Metaphor

A purposeful life is a journey.

A person living a life is a traveler.

Life goals are destinations

A life plan is an itinerary.

 

This metaphor has strong influence on how we conduct our lives. This influence arises from the complex metaphor’s entailments: A journey, with its accompanying complications, requires planning, and the necessary means.

 

Primary metaphors ‘ground’ concepts to sensorimotor experience. Is this grounding lost in a complex metaphor? ‘Not by the hair of your chiney-chin-chin’. Complex metaphors are composed of primary metaphors and the whole is grounded by its parts. “The grounding of A Purposeful Life Is A Journey is given by individual groundings of each component primary metaphor.”

 

The ideas for this post come from Philosophy in the Flesh. The quotes are from Where Mathematics Comes From by Lakoff and Nunez

I challenge the student of mathematics

Okay, I'll bite. This post has been bugging me for a while and honestly I just want to know what on earth your point is.

It appears to me that most people look on math as something with supernatural qualities.

I think I see what you mean here, but I wouldn't agree with your choice of words. I find that lots of people see maths as something incomprehensible and detached from their natural understanding.

I challenge the student of math to develop and post short essays on Internet discussion forums about those fundamental aspects of math that you think people can and should comprehend[... some philosophical stuff ...]

Okay this bugs me, the philosophy of maths is fun - and the physchological aspects are interesting but really, I couldn't care less what other people know about them. If there are things that the vast majority of people should know about maths then it should be things like what the word average means, why breaking distance is proportional to the square of velocity and why casinos have upper limits to the amount you can gamble even though the odds are always in their favour.

I am educated a bit better than your "ordinary citizen", but I'm not 100% sure what you're talking about.

 

The "ordinary citizen" clearly has a vocabulary which is significantly smaller than yours... and it uses maths to solve every-day problems, not to study its own brain or something.

Indeed - all the everyday applications are really pretty important, and worth learning about for anyone but the purely academic side is just that.

Can anyone remember the name of the mathematician who studied number theory because he was sure the military couldn't use it? He was rather put out when they started using it to encrypt signals.

 

As with a lot of things in science (and I don't know or care if maths is a science) today's obscure academic stuff is tomorrows everyday aplication.

 

(This image may well be brought to you using fractal compression- 20 years ago fractals were just pretty pictures that math's geeks played with).

Just fyi guys, coberst is an old, old spammer. Look up this exact topic. I've seen it on at least 3 fora I go to. It's apparently on at least 30 of them, according to google.

 

The idiot rarely returns to his threads - I've only ever seen it 3 times, and with barely any real contributions. Usually he just reposts an old reply when people ask the same questions as others did on other fora, without even trying to do anything new with it. He doesn't discuss anything.

Oh yeah, of course. I was just saying that it's not massively important that the public should know about the abstract philisophical musings when there's all the all the everyday groundwork to be laid, which is not only useful to more people, but interesting to more people as well - same with all the sciences really.

Oh, okay.
