Discussion Overview

The discussion revolves around the philosophical and mathematical implications of the statement "one and one makes two," using the example of adding chewing gums. Participants explore the nature of addition, cardinality, and the distinction between quantity and quality in mathematical contexts.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Mathematical reasoning

Main Points Raised

  • Some participants question the meaning of "add" in the context of chewing gums, suggesting that the act of addition can vary based on interpretation.
  • One participant introduces the concept of cardinality, discussing how the cardinal of a set is independent of its elements.
  • Another participant presents different approaches to addition, including absolute and relative methods, leading to various interpretations of the result of 1 + 1.
  • There is a humorous exchange regarding the nature of chalk and chewing gum, with participants making light of the philosophical implications of their sizes and quantities.
  • Some participants reference historical figures and works, such as Newton and Asimov, to illustrate their points about mathematical reasoning and philosophical inquiry.
  • One participant raises the idea that the question of adding chewing gums could indicate a need for a new branch of mathematics to address such philosophical dilemmas.
  • There is a discussion about the relationship between quantity and quality, with references to Newton's equalization of different types of acceleration.

Areas of Agreement / Disagreement

Participants express a range of views on the nature of addition and its implications, with no clear consensus reached. The discussion remains open-ended, with multiple competing interpretations and approaches presented.

Contextual Notes

Participants highlight the ambiguity in definitions and the philosophical underpinnings of mathematical concepts, indicating that the discussion is influenced by varying interpretations of terms like "addition" and "quality." Some mathematical steps and assumptions remain unresolved.

The whole chalk talk is from Isaac Asimov.

The book is Asimov on Numbers - Isaac Asimov.

He talk abouts a professor who says Mathematicians are maniacs of some sort, and he goes off to finish his case against the angry professor.

Yes, I have read it.

What made me post this thread is Newton's way of equalizing force - mass ratio with angular and linear acceleration at the same time despite the fact that the last have different qualities - units. Newton cannot make a difference between degrees and meters.

The units for linear acceleration are meters/sec^2
The units for angular acceleration are rad/sec^2

It is a simple matter to see how many meters an object travels along the circumference of a given circle if the radius of the given circle is known. This makes the relationship between radial acceleration and tangential acceleration apparent.

Acceleration is defined as a change in velocity over a time. Since velocity is a vector, there are two ways to produce acceleration: by a change in magnitude or by a change in direction. I don't see any flaws in Newton's laws here. The angular (radial) acceleration is perpendicular to the tangential acceleration.

The total acceleration is equal to the square root of (angular acceleration^2 + tangential acceleration^2)

For some reason, you seem to be intent on discrediting Newton. That's ok; because each time you are proven wrong, the students on this forum get a better understanding of classical physics during the course of the discussion. So in your own way, you are providing a valuable service to many people. If this is your purpose, than I would like to thank you for your contribution.
