Discussion Overview

The discussion revolves around the nature and naming of "Space" from both mathematical and physical perspectives. Participants explore concepts related to Euclidean space, Minkowski space, and the implications of physical space in relation to mathematical models.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that the space surrounding us is Euclidean space, as it describes three-dimensional points.
  • Others agree that we live in Euclidean space but introduce the idea of manifolds and spacetime when considering movement beyond everyday experiences.
  • One participant argues that physical space should not be conflated with mathematical definitions, suggesting that while Euclidean and Minkowski spaces are useful models, they do not represent physical reality directly.
  • A participant questions the naming of space in the context of a bouncing ball, suggesting it can be modeled mathematically in Euclidean space.
  • Another participant humorously remarks that the naming of space may be subjective, referencing a literary quote about names.
  • One contribution describes the space of a bouncing ball as consisting of three spatial dimensions and one temporal dimension, indicating a more complex understanding of space and time.

Areas of Agreement / Disagreement

Participants express a mix of agreement and disagreement regarding the naming and nature of space. While some assert that it is Euclidean space, others challenge this view, emphasizing the distinction between physical and mathematical interpretations. The discussion remains unresolved with multiple competing views.

Contextual Notes

There are limitations in the assumptions made about the nature of physical space versus mathematical models, and the discussion does not resolve the complexities involved in defining space in different contexts.

TL;DR
What is the mathematical name of the space that I am living in?
I am surrounded by Space and so I am curious to know what the name of this Space is. Is this Space given any name by a Mathematician? I suspect that this Space may be called Euclidean Space because Euclidean Space knows how to present point in three-dimensions. Euclidean Space talks about three-dimensions. Euclidean Space can tell me how to put a point in three-dimensional Space.

Yes, you live in Euclidean space.

Unless he takes a flight, then he lives on a manifold.

And if he is rich enough to go to space, he will live in spacetime.

Euclid - Newton/Riemann - Einstein ... and everybody is looking to become the next one in that row :smile:

Newtonian mechanics uses an Euclidean space. Special relativity uses a Minkowski space. In general relativity we have a Minkowski space locally, but the global structure is more complicated.

Frankly, your question makes no sense! You say "I am surrounded by Space" and since your are a physical object, you are talking about physical space! No, that space is NOT given any name by a Mathematician. Physics is not Mathematics! With apologies to Math_QED physical space is NOT "Euclidean space" although as a mathematical model it might be a good approximation. And would say the same about Minkowski space- as a mathematical model perhaps a better approximation but still an approximation and a model, not a real physical thing.

If I say that: There is a ball that is bouncing.
What would be the name of the Space?

Thanks.

Living room?

It can be mathematically modeled in an Euclidean space.

A rose by any other name would smell as sweet.

The ball exists in a space of three spatial dimensions and one temporal (time measurement) dimension. As the ball moves up or down, its position in the spatial dimensions changes, and the time changes.
