> 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°
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
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.
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.

[ 2.8 ms ] story [ 52.4 ms ] threadI do assume that the notion is used and also implies the 'resolution'/'precision' of that number.
The ideal isn't straight on.
at least in chem
