Fine-Structure Constant (approx. 1/137) is a dimensionless constant that characterizes the strength of the electromagnetic interaction between elementary charged particles. Its value is approximately 1/137, and it's one of the fundamental constants of nature whose origin remains… pic.twitter.com/VIteZcu4K2

* e is the elementary charge (1.602176634×10−19 C);
* h is the Planck constant (6.62607015×10−34 J⋅Hz−1);
* ħ is the reduced Planck constant, ħ = h/2π (1.054571817...×10−34 J⋅s)
* c is the speed of light (299792458 m⋅s−1);
* ε0 is the electric constant (8.8541878188(14)×10−12 F⋅m−1).
So the Fine-Structure Constant is essential in defining the electromagnetic force, one of the four fundamental forces in nature.
