Discussion Overview

The discussion revolves around the effects of distance on the landing of a bouncing die, particularly in relation to chaos theory and quantum mechanics. Participants explore how precise conditions of the drop and various physical factors might influence the outcome of the die's landing.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that if a die is dropped from a controlled apparatus with precise conditions, it may follow the same path each time, but raises the question of quantum mechanics and probabilities in landing.
  • Another participant emphasizes chaos theory, noting that even slight variations in the drop angle or conditions could lead to different outcomes, alongside the influence of air motion and thermal effects.
  • A third participant argues that quantum effects are unlikely to be significant in this scenario, asserting that a well-constructed drop mechanism would yield consistent results, especially with larger dice compared to smaller objects like BBs.
  • There is a query about whether a BB would be influenced by quantum mechanics, prompting discussion about the scale at which quantum effects are relevant.
  • One participant posits that the distance from which the die is dropped could amplify imperfections, suggesting that this is not related to quantum mechanics but is still a relevant factor.

Areas of Agreement / Disagreement

Participants express differing views on the relevance of quantum mechanics versus chaos theory in the context of the die's landing. There is no consensus on how these factors interact or the extent to which they influence the outcome.

Contextual Notes

Participants acknowledge various assumptions, such as the precision of the drop mechanism and the influence of environmental factors, but these remain unresolved within the discussion.

Who May Find This Useful

This discussion may be of interest to those exploring the intersections of physics, particularly chaos theory and quantum mechanics, as well as practical applications in experimental setups involving randomness and precision.

Lets say you have a die and a galton board (a vertical array of pegs used to demonstrate the normal distribution), you build some kind of apparatus that will allow you to drop the die from the exact location, with the exact degree of tilt, ect, repeatedly. You also have a super slow motion camera to capture its decent.

Question: Will the die follow the exact path each time, and land on the same side? I have heard that quantum mechanics says that the die would only have probabilities of where it would land.

It's more chaos theory, how accurately can you drop it at exactly the same angle in the same point. Then you have to worry about air motion, then the thermal motion of atoms on the surface of the die and the pegs.
 
Yeah. Quantum effects are not going to manifest themselves very readily in your situation. the more exact you build the dropper, board and what not, the more consistent your die drop will be. If you use something as large as a cubic die, you can ensure that you get the same value. Something smaller like a BB would get you more random results.

So would a BB actually be affected by quantum mechanics? I am just wondering if quantum mechanics theoretically happens on the scale of inches, feet, miles, ect, or if it is only something that occurs at the level of photons, electrons, ect.
 
I would have though that the distane in which the die is dropped would have an effect, as the further it is dropped the greater any imperfection will be exagerated, this is the same as with the size of the bases of the die. This itself I do not think is in any way related to Quantum mechanics but I think it still apllies.
