Add the first digit (1) to the other digits collectively (37+1) =~ 38Physics Guy wrote: ↑Mon Dec 18, 2023 10:39 amIf High Spy wants to figure out special numbers, he could maybe try this one: 137. What is arguably the most important natural constant, the fine structure constant, is a pure number, without any units. It's very close to (but not quite exactly) 1/137. No-one knows why it has the value it has.
Most natural constants are really just unit conventions based on human preferences. We could perfectly well adopt the light-nanosecond as our unit of distance—it's about a foot—and then the speed of light would just be the number one billion, without any units, because "seconds per second" doesn't need saying. It's really only ratios of similar things that are objective facts. The fine structure constant is such a ratio. Among other things it relates the size of the smallest atom to the mass of an electron.
Add the first digit (1) to the other digits individually (3+1) (7+1) =~ 48
PI too is a pure number.
Men have 10 digits between 2 hands.
360 approximates the number Earth of days/year.
What pure number derives from having 10 digits and a circle with 360 degrees?
Truncate it at 6 significant digits.
How does it begin?
How does it end?
