> point of a convex hull
This suggests a point on the exterior surface.
> accepting the new point if it stays inside the convex shape
This suggests a point in the interior volume.
Could you reword to avoid ambiguity? (more) |

Although it can be surprising when someone first learns that the volume of a cone or pyramid is independent of the shape of the cross section, that seems to be only a step towards understanding the surprising result presented in the question.
The area of the n-gon at the base of the pyramid will b... (more) |

Note that [the definition of "miffed"](https://en.wiktionary.org/wiki/miffed) can vary in different regions. In many places "miffed" means upset or irritated, so the usage in this question could cause confusion. It might be more widely understood if "made a mistake" were used instead. (more) |

A: How can you forebode that amount of wood in a napkin ring is the same, regardless of the size of the sphere used ? > (a) Guess which ring has more wood in it. The word "guess" shows that this is not necessarily intended to be guessed correctly. The guess is asked for precisely because the result is unintuitive, and surprising to most people. Writing down your guess emphasises the contrast between what you init... (more) |

I don't know how many students you teach per year, but if only a little over 1 per year makes this mistake, it sounds like the large majority understand correctly. Are you concerned because you consider this proportion to be unexpectedly high, or because you can't relate to making the mistake at all?... (more) |

No problem. I can parse it all now. Interesting conjecture. I'll be interested to see if someone can prove it either way. (more) |

I'm having difficulty understanding the second paragraph. If I've understood the intuitive idea behind the question, then I suspect there may be some typos, but I'm not sufficiently confident in my understanding of your intention to suggest a specific edit.
- Should $2^{n-1}$ instead say $2^n-1$?

> It is rude to alter one's post
It is rude to alter the author's intent. The problem is that sometimes the editor does not realise that a small change is in opposition to the author's intent. It is not rude to make small fixes - that is how the site is intended to work. When people edit with good... (more) |

Looks like Peter Taylor has now edited that answer to add double back slashes before every dollar sign, which seems to have the intended effect.
Looks like there are still issues with this. The edit history of that answer shows 2 new backslashes per dollar sign, but only 1 of them is marked as an ... (more) |

Some (most?) implementations of minesweeper do not allow a mine to be hit on the first square that is uncovered. Internally, this may involve recalculating the mine positions if the first square uncovered happens to be a mine, so the player never knows.
Can we assume that this applies, so the play... (more) |

A: Closed-form expression for sum of Modulo Arithmetic Progression Assumed question Placement of parentheses Your final paragraph suggests that you would already know how to evaluate the following expression: $$ \Bigl( \sum{i=1}^{N} (a \cdot i) \Bigr) \bmod{M} $$ I will therefore assume that your question concerns the following expression: $$ \sum{i=1}^{N...

It would be useful to have this answered by adding parentheses to the formula so it is immediately clear. (more) |

I agree this question should be closed. Analysing a long article seems a better fit for a blog than an answer on this site.
As Peter Taylor pointed out, it is possible to profit from some lotteries. However, lotteries close loopholes over time, particularly loopholes that have been made public. It... (more) |

Hovering over the voting buttons and vote counts currently shows the score when in a question page, but it doesn't yet show on question list pages.

I agree a fractional score would be horribly confusing (especially as not all Codidact communities are maths based). An integer percentage might work better but could give the impression of far more voters than there really were.

I share this impression - I raise a lot of issues (some important, some trivial) and see frequent fixes and feature implementations, which encourages me to continue raising whatever I notice. It's really useful to have your first impressions. I hope you'll continue to raise things. (more) |
