    Which is why ten is such a bloody silly choice for a number system base. We should be using sixty and/or twelve!
    And don't get me started on our use of c/d instead of c/r to describe the fundamental circle constant!

    Voting is not just a matter of those who vote, but also of those who count.
    #GOP government attempts to prevent non-GOP citizens to be involved in #counting #votes in the #midterms. For transparency, citizens of all political backgrounds and affiliations must participate in the counting. If trump succeeds in manipulating the #midterms in his favour, the USA will cross another thin line towards #dictatorship. #nofascism

    🔥 chaos’ in Georgia’s elections

    An #election #denier praised by Trump sits on the state’s elections board
    -- which has just #required #hand-#counting ballots on Election Day

  8. Why is it that we have so many #counting concepts up to 12 or 60 like hours/minutes/12 pence in a shilling?

    en.wikipedia.org/wiki/Duodecim gives a speculatively explanation: it's based on a different way of using our fingers to count.

    One thumb is an indicator that goes through all the 12 knuckle bones of the four larger fingers.

    The other hand uses all 5 #fingers to count the number of dozens which enables you to count up to 60.

    Seems a reasonable explanation to me.

  9. In the process I also thought of a #binomial #coefficient interpretation for choosing k things out of a bag of n objects when the objects can be put back and picked again. In probability problems, this is referred to as picking "with replacement".

    Usually, when we say, n choose k, we do not allow repeated choices, every chosen object has to be chosen once. In this case, I want to allow replacements but at the same time, I want to keep using my trusted n choose k idea.

    Here's my way around this: We'll still be picking k things, but we'll pick them not from 1 to n but from the set {1, 2, ..., 𝑛, 𝑟₁, 𝑟₂, ..., 𝑟ₖ₋₁}. That is, in addition to the n objects, we add what I'm calling "replacement tokens" 𝑟ₓ. If any of the 𝑟ₓ gets picked, then it is interpreted as the 𝑥th choice was put back and you are now choosing to pick that again. Since the 𝑘th choice is not put back, we only need replacement tokens for choices 1 to k-1.

    With these replacement tokens, the problem becomes a standard choose k things out of this set, which we can resolve using the binomial coefficient to get: \({ n+k-1 \choose k }\).

    I believe the standard approach to this is via #StarsAndBars but I liked the idea of this "replacement token". Admittedly, I didn't want to use stars and bars here and made up some stuff which I happened to like. :)

  10. Number #two has a very interesting #etymology: Despite the differences between two, #dva #doi and #zwei, they come from the same Proto-Indo-European root: dwóh₁.
