Discussion Overview

The discussion revolves around the relationship between mathematics and the representation of imperfect shapes found in nature. Participants explore why mathematics often employs idealized geometric forms, such as perfect spheres and triangles, despite the irregularities present in the natural world. The conversation touches on applications in architecture and engineering, as well as the philosophical implications of using perfect shapes to model reality.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions why mathematics focuses on perfect shapes when nature is filled with imperfect forms, citing the Earth's shape as an example.
  • Another participant suggests that while mathematics uses ideal shapes, they often serve as good approximations for more complex forms.
  • Fractal geometry is mentioned as an inspiration derived from the imperfections of nature, indicating that natural geometry can involve more specialized mathematical concepts.
  • Some participants express skepticism about the reliance on perfect shapes, questioning whether mathematics should be guided by natural forms.
  • There is a discussion about the practicality of using perfect shapes as a basis for approximating other shapes in mathematical applications.

Areas of Agreement / Disagreement

Participants express differing views on the appropriateness of using perfect shapes in mathematics. While some acknowledge the utility of these shapes as approximations, others challenge the notion that mathematics should be guided by nature, indicating an unresolved debate on the topic.

Contextual Notes

Some claims about the relationship between natural shapes and mathematical representations remain conditional, and there are unresolved questions regarding the extent to which mathematics can accurately model the complexities of nature.

Who May Find This Useful

This discussion may be of interest to those exploring the philosophical implications of mathematics in relation to the natural world, as well as individuals studying geometry and its applications in various fields.

Why does mathematics deal with the world of perfect spheres, triangles and squares. I understand how this can be applied to architecture and engineering. But this seems counter-intuitive to 'nature' that surrounds us which is objects that are not perfect in shape. The Earth for instance isn't a perfect sphere it budges out at the equator. So why is mathematics always prone to using perfect angles and objects to be measured when nature isn't that way at all.

Thank you

Mathematics uses other shapes, too. But often, circles, triangles and so on are good approximations. In addition, they are used as introduction as they are easier to treat than other shapes.

The Earth for instance isn't a perfect sphere it budges out at the equator.
Plus many more corrections to the shape.
 
nature isn't that way at all.

That is what inspired fractal geometry.

Natural geometry also follows some more specialised mathematics - spirals, fibonacchi series, and some very complicated equal area shpes.

Note also that the word geometry derives from 'measurement of the Earth'.

Why should nature guide maths?

I guess the way i see it is. I was mainly just wondering why math uses examples from natural world it's perfect objects seems a bit unrealistic. Though I am no mathematician i would think mathematics becomes so approximate that any shape of nature can be imagined.
 
And what should you approximate reality FROM, if not from the "perfect" shapes?

You can call a rectangle a perfect, unrealistic figure for all you like, but it is from the rectangle and its associated area formula that you can basically derive the area of any other shape.
