Infinite Dimensional Infinitesimal

AI Thread Summary
Any smooth connected 1-dimensional manifold is either diffeomorphic to a circle or an interval of real numbers. The discussion illustrates this concept by taking a line segment and rotating it into higher dimensions, demonstrating that as dimensions increase, the segments approach a limit where an infinite-dimensional universe can be considered a point. The conversation also touches on the implications of dimensionality, questioning how rotations contribute to dimensionality and referencing the limitations of the alphabet in expressing these concepts. The relationship between dimensions and geometric representation is a key focus, highlighting the complexity of understanding higher-dimensional spaces. Ultimately, the discussion emphasizes the mathematical principles underlying manifold theory and dimensionality.

Any smooth connected 1 dimensional manifold is diffeomorphic either to the circle, or to some interval of real numbers.

Take a line segment of length 1. It is one dimensional.

A-------B

Find the midpoint of the line segment and rotate it into 2 dimensions

Each leg is 1/2

Rotate into 3 dimensions, and each leg is 1/3

A

B



rotate into N dimensions and each leg is 1/N

Continue this process as a limit

N---->oo

By the above process, an infinite dimensional universe is a point.

So this is four-dimenisional?..how do you account for the fact there is only 26 letters in the alphabet?

The problem is that a Four dimensional space has inner products made from A+B..A Rotation does not constitute a added Dimension?
