SUMMARY

The discussion centers on the concept of "one out of infinity" and its relationship to zero, particularly in the context of probability and mathematical definitions. Participants clarify that infinity is not a number and that expressions like 1/∞ are undefined in standard arithmetic. They emphasize that in traditional number systems such as integers, rationals, and reals, there is no concept of "infinitely small" quantities, and thus one cannot equate one out of infinity with zero. The conversation also touches on the limitations of using ordinary language to describe mathematical concepts, highlighting the need for precise definitions.

PREREQUISITES
  • Understanding of basic probability theory and its axioms, particularly the Kolmogorov Axioms.
  • Familiarity with the concept of infinity in mathematics.
  • Knowledge of different number systems, including integers, rationals, reals, and hyperreals.
  • Basic algebraic concepts, particularly limits and their properties.
NEXT STEPS
  • Research the properties of hyperreal numbers and their applications in calculus.
  • Study the Kolmogorov Axioms of probability theory to understand the foundations of probability.
  • Explore the concept of limits in calculus, particularly how they relate to infinity.
  • Watch educational videos on Hilbert's hotel and other paradoxes involving infinity to deepen understanding.
USEFUL FOR

High school students studying algebra and calculus, educators teaching probability theory, and anyone interested in the philosophical implications of infinity in mathematics.

Why not just use a RNG on the interval?

A RNG can't generate a random number out of an infinite set. Nor, if you are talking about the uncountable interval (0, 1), can it generate infinite decimals. A RNG can only randomly choose an element from a finite set.
