Single Idea 19375

[filed under theme 6. Mathematics / A. Nature of Mathematics / 5. The Infinite / j. Infinite divisibility ]

Full Idea

Leibniz said the division of the continuum should not be conceived 'to be like the division of sand into grains, but like that of a tunic or a sheet of paper into folds'.

Gist of Idea

The continuum is not divided like sand, but folded like paper

A Reaction

This from the man who invented calculus. This thought might apply well to the modern physicist's concept of a 'field'.


The 6 ideas with the same theme [endless dividing an interval between numbers]:

Lengths do not contain infinite parts; parts are created by acts of division [Aristotle, by Le Poidevin]
A continuous line cannot be composed of indivisible points [Aristotle]
The continuum is not divided like sand, but folded like paper [Leibniz, by Arthur,R]
There is no continuum in reality to realise the infinitely small [Hilbert]
Between any two rational numbers there is an infinite number of rational numbers [Friend]
Infinitesimals were sometimes zero, and sometimes close to zero [Colyvan]
