New definitions to the continuum and the discreteness concepts

Click For Summary
SUMMARY

The discussion centers on the definitions of continuum and discreteness in relation to real numbers p and q. The original poster, Doeon, presents definitions for intervals and connections between real numbers but is corrected by HallsofIvy, who points out the lack of precision in the statements. The key takeaway is that the definitions provided by Doeon require refinement to accurately reflect mathematical principles, particularly the distinction between mathematics and physics. The conversation emphasizes the importance of clarity and precision in mathematical definitions.

PREREQUISITES
  • Understanding of real number intervals
  • Familiarity with mathematical terminology such as "continuum" and "discreteness"
  • Basic knowledge of logical operators, specifically XOR
  • Conceptual grasp of mathematical precision and definitions
NEXT STEPS
  • Research formal definitions of continuum and discreteness in mathematics
  • Study the properties of real number intervals and their notation
  • Learn about logical operators and their applications in mathematical proofs
  • Explore the differences between mathematical concepts and their physical interpretations
USEFUL FOR

Mathematicians, students of mathematics, and anyone interested in the precise definitions of mathematical concepts related to real numbers and logical operations.

p and q are real numbers.


If p < q then

[p,q] = {x : p <= x <= q} or
(p,q] = {x : p < x <= q} or
[p,q) = {x : p <= x < q} or
(p,q) = {x : p < x < q} .


A single-simultaneous-connection is any single real number included in p,q
( = D = Discreteness = a localized element = {.} ).

Double-simultaneous-connection is a connection between any two real numbers
included in p,q ( = C = Continuum = a non-localized element = {.___.} ).


Therefore, x is . XOR .___.


Please tell me what do you think ?

Okay, you asked:

The first point I would make is that your very first statement:

If p is not equal to q then

[p,q] = {x : p <= x <= q} or
(p,q] = {x : p < x <= q} or
[p,q) = {x : p <= x < q} or
(p,q) = {x : p < x < q} .

is not true. It's only true if p<q and you only said "p is not equal to q".

It's a minor point but symptomatic of your tendency to say things sloppily and without precision. All you are really doing is using big words in non-standard ways without bothering to give precise definitions.

Basically, you do not understand what mathematics IS, and, in particular, the difference between mathematics and physics.
 
Hi HallsofIvy,

Thank you for your correction, I am learning from you "on the fly" therefore
I am going to fix my definition and write p>q instead of "p is not equal to q".

Now, after I fix it, please show me by using a formal mathematical way, why my definitions to . XOR ___ are not precise.

Thank you.

Doeon
