    This reminds me of previous work showing where you should aim in darts (https://www.stat.cmu.edu/~ryantibs/darts/). Basically, if you're very accurate you should aim at the 20, but next to it are 1 and 5, so if you're less accurate there are more forgiving spots on the board.

    Question: the authors use the term "inhomogeneous" to describe the oil pattern. Is there a difference between heterogeneous and inhomogeneous?

    • TheJoeMan 6 days ago

      Heterogeneous refers to a mix of dissimilar compounds, while inhomogeneous is more about a varying of properties throughout a single compound.

      So in the abstract, the friction surface is called inhomogeneous because it's referring to the floor as one component with a varying friction coefficient.

      subtle difference: "heterogeneous" generally implies a mixture of distinct, separate elements or components, while "inhomogeneous" can refer to a lack of uniformity in properties within a single substance

      at least in chem

    Now lets see it with candlepin.

      > It has been shown that the optimal location for the ball to hit the headpin is 6 cm offset from the center, and the optimal entry angle for the ball to be incident to the pin at is 6°

      The ideal isn't straight on.

        I thought this was common knowledge, that's always been the spot I've aimed for (~5-6cm to the right of the headpin) since the 80s.

      That’s not what this paper says.

      Its a physics paper and not a news paper article.

      I do assume that the notion is used and also implies the 'resolution'/'precision' of that number.

      • Calwestjobs 6 days ago

        why do people numbers need resolution, emphasis but dollar amounts does not?

          One has a source, the other is a figure of speech without a source.
