Quantum Theory vs. Relativity: Explained in Layman's Terms

Click For Summary

Discussion Overview

The discussion centers on the differences between quantum theory and relativity, with a focus on understanding these concepts in layman's terms. Participants explore the fundamental principles, applications, and implications of both theories.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant requests reading materials that explain the main differences between quantum theory and relativity in layman's terms.
  • Another participant outlines that quantum theory deals with particle kinetics, while relativity is divided into special relativity, which relates to time and space, and general relativity, which relates to universal gravitation and object kinetics.
  • A different participant emphasizes that both subjects are vast and complex, suggesting that quantum theory describes very small phenomena in a probabilistic manner, whereas relativity describes very large phenomena in a deterministic manner.
  • One participant inquires about the consensus among physicists regarding which theory provides significant explanations of physical forces.
  • A response indicates that both theories are useful depending on the modeling context and that they provide descriptions rather than explanations.
  • Another participant expresses a desire for more explanatory content regarding physics rather than just descriptions.

Areas of Agreement / Disagreement

Participants express differing views on the nature of explanations provided by quantum theory and relativity, with some emphasizing descriptions over explanations. There is no consensus on which theory is more widely accepted for explaining forces in physics.

Contextual Notes

Participants acknowledge the complexity of both theories and the challenge of summarizing their differences adequately, indicating that a full understanding may require extensive discussion.

can someone tell me what to read in "layman " terms ,the main differences between quantum theory and relativity?
 
Physics news on Phys.org
quantum theory explain the law of particle kinetic.
relativity is divide into restricted theory of relativity and general theory of relativity
.restricted theory of relativity mainly assume the relation of time and space.general theory of relativity mainly assume the relation of universal gravitation and object kinetic.
 
These are enormous subjects, and they have both glaring and subtle differences. It would take pages and pages of explanations, even at the layman level, to give this question a real answer.

If I had to sum it up in one sentence, I would say: Quantum theory describes the behavior of very small things, and is fundamentally discontinuous and probabilistic, while relativity describes the behavior of very large things, and is smooth and deterministic.

thanks a lot croot,can you tell which of them or both enjoy the consensus of physicists in explaining forces of physics that provides significant explanations of our world?
 
Both, depending on what you want to model.
And they don't provide explanations, only descriptions.
 
thanks mike,enlighten me with some explanations of physics,and not merely descriptions.
