Why the number 137 is one of the greatest mysteries in physics

https://bigthink.com/surprising-science/why-the-number-137-is-one-of-the-greatest-mysteries-in-physics

<snip>
The brilliant physicist Richard Feynman (1918-1988) famously thought so, saying there is a number that all theoretical physicists of worth should "worry about". He called it "one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man".

That magic number, called the fine structure constant, is a fundamental constant, with a value which nearly equals 1/137. Or 1/137.03599913, to be precise. It is denoted by the Greek letter alpha - ?.

What's special about alpha is that it's regarded as the best example of a pure number, one that doesn't need units. It actually combines three of nature's fundamental constants - the speed of light, the electric charge carried by one electron, and the Planck's constant, as explains physicist and astrobiologist Paul Davies to Cosmos magazine. Appearing at the intersection of such key areas of physics as relativity, electromagnetism and quantum mechanics is what gives 1/137 its allure.

Physicist Laurence Eaves, a professor at the University of Nottingham, thinks the number 137 would be the one you'd signal to the aliens to indicate that we have some measure of mastery over our planet and understand quantum mechanics. The aliens would know the number as well, especially if they developed advanced sciences.

Of course, if they're really advanced, they'd know that that's what we use. What would we make of contact from an extraterrestrial that resolved to the number 137?

A repeating string of 137 pulses would work.

10001001 would be easy to express as well, would be fairly universal

Arabic numerals, also called Hindu–Arabic numerals,[1][2] are the ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9; or numerals written using them[a] in the Hindu–Arabic numeral system[5] (where the position of a digit indicates the power of 10 to multiply it by). It is the most common system for the symbolic representation of numbers in the world today.

use the same underlying alphabet -- much like English, French and Spansih all use the Latin alphabet.

It’s more of that sense of *AWE*— things that the human mind can take so far, then the road ends...but there is still territory ahead.

Thanks for posting this, it’s a nice break from all the election-saturation.

For me it's the number 48 because pops up all the time and I have no clue why. This has been going on since the early 1970s.
