Discussion Overview

The discussion centers on the fairness of dice rolls, specifically examining the symmetry and center of gravity of classic six-sided dice with carved out pips. Participants explore how these factors might influence the likelihood of rolling certain numbers, particularly focusing on whether imperfections or the weight distribution of the dice affect outcomes.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that a perfectly symmetrical die with carved out pips may not have its center of gravity at the center of the cube, potentially leading to biased rolls.
  • Another participant proposes that the number 6 could appear more frequently than expected due to it being the lightest side opposite the heaviest side, raising questions about weight distribution.
  • Some participants agree with the idea that the number 6 may come up more often, although the reasoning is not universally accepted.
  • One participant argues that any potential effects of weight distribution would likely be overshadowed by other imperfections in the dice.
  • Another participant assumes a scenario without imperfections, suggesting that the impact of carved out pips would still be significant.
  • A humorous remark is made regarding the use of lead-based paint on colored pips, questioning the integrity of dice produced in certain conditions.

Areas of Agreement / Disagreement

Participants express differing views on whether the center of gravity affects the fairness of dice rolls, with some supporting the idea that it does while others believe imperfections in the dice would have a greater impact. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

Participants note the assumptions regarding the symmetry of the dice and the potential influence of imperfections, but do not reach a consensus on the significance of these factors.

A classic die is six sided with pips of equal depth. It seems to me that if it is perfectly symmetrical and the sides are in the classic configuration (opposite sides total 7) the center of gravity will not be in the center of the cube. Correct? Has anyone ever tried to figure out where it is? And if it isn't wouldn't they have a tendency to roll a particular number more? (this would only apply to dice with carved out pips, casino dice have colored pips so they would roll true)
 
Physics news on Phys.org
I have been thinking about this a bit since I wrote the question and it seems to me that the 6 will come up the most often, more than 1/6th of the time because it is the lightest side and it is opposite the heaviest. This is slightly relevant because almost every consumer die has carved out pips.
 
seems right
 
6 is it
 
The effect would probably be swamped by other imperfections in the dice.
 
I was assuming no imperfections and even if there were they would be relatively insignificant compared to the amount of material that is carved out by the pips in all but the cheapest crap made in China.
 
Well, I suppose colored pips would be more "true" as long as one wasn't using, say, lead-based paint.
Oh wait, I forgot, China uses lead-based paint !

Sorry... couldn't resist.
 
lol Actually that would be negated by the lead in the plastic.
