      It's amazing how a professional mathematician saying things that any professional mathematician would readily accept as non-controversial gets a bunch of dickhead conservatives screaming and pounding on the tablehttps://twitter.com/ConceptualJames/status/1288957167844962306 …

      Kids, never doubt yourself. You can achieve anything, including getting math educators to double, triple, and quadruple down on 2+2=5 so they won't have to admit their political and epistemological views are literally Orwellian. pic.twitter.com/KBDlMbc8N2

      Even just an example that everyone is screaming about as logic-chopping and cheating is a good and important example worth thinking about That it's easy to add 2 pounds to 2 pounds and get 5 pounds, if you're using a scale that rounds 2.2 and 2.4 down to 2 and rounds 4.6 up to 5

      Replying to @arthur_affect @perdricof

      The issue is common understanding for meaningful communication among a general public. On your example, how is that hypothetical scale better than the sort you encounter in real life? Seems definitively less precise, no?

      All scales that exist in the real world are this scale, it just depends on the scale (so to speak)

      Does some degree of rounding? Sure. The degree you present? I don’t want to pay for (ca) 5 pounds of meat with (ca) 4.6 pounds. And again, this is a deflection of the point of general communication/ common understanding.

      Yes, I understand that you think mathematical education is just a matter of telling kids how to punch numbers into the calculator on their iPhones and that any further thought about the relationship between those abstract functions and the real world is a woke waste of time

      What I am telling you is that it is your version of mathematical education that is a pointless waste of time (why the hell would anyone, even a small child, actually need me to "teach" them that "2+2=4" in the trivial sense)

      And what you are doing is very much the negative form of "virtue-signaling" (setting up a strawman and tilting wildly against it)

      Again: shared understanding, basic communication, the point you’re still deflecting. The degree of rounding in your scale scale would not bode well in a street market for a reason.

      Hey, here's a fun thing that you understand if you actually understand math: 0.0000000002 + 0.0000000002 = 0.0000000005 isn't different from 2 + 2 = 5

          and depending on your currency 0.02 + 0.02 would have to come to a 0.05 payment because a lot of countries don't have single-cent (or equivalent) coins anymore.

          Or how about gas in the U.S. where it is usually X.YZ⁹/₁₀. Let's say it is 2.02⁹/₁₀ per gallon. 2 gallons would be 4.05.

          I find it very ironic that ter*s claim to be so opposed to rounding errors when calling bimodally distributed sex a binary is such a core component of their whole deal.

          Fun fact - this is actually how Canadian cash payments work, because they round to the nearest $0.05. If you buy one thing for $1.02 it actually costs $1.00 in cash but if you buy two of them they cost $2.05.

          This is an argument for imprecision by drilling down to a number so small we would and do round. While the same on paper, rounding || || to ||||| when each unit matters does not correspond to something acceptable in the real world where we should try to be as precise as possible.

          It is not an argument "for" imprecision, it is an argument that imprecision always exists (or to rephrase, that precision is finite) You don't really know what you're talking about
