“In a reasonable theory there are no (dimensionless) numbers whose values are only empirically determinable.”[1] “Dimensionless constants in the laws of nature, which from the purely logical point of view can just as well have different values, should not exist. To me, with my ’trust in God’ this appears to be evident, but there will be few who are of the same opinion.”[2]—A. Einstein
A dimensionless physical constant (sometimes fundamental physical constant) is a physical constant that is dimensionless—having no unit attached, so its numerical value is the same under all possible systems of units. The best known example is the fine structure constant α ≈ 1/137.036.
