In this video Dirac talks about the Fine Structure Constant 1/137.
Can we now explain why this is?

It works, but that’s what makes it a good joke.Quantum_Physics123 said:I tested out the equation above on a calculator and it works!
The Fine Structure Constant, often denoted by the Greek letter alpha (α), is a dimensionless constant that characterizes the strength of the electromagnetic interaction between elementary charged particles. It is approximately equal to 1/137 and plays a crucial role in the equations of quantum electrodynamics (QED).
The Fine Structure Constant is important because it determines the strength of the electromagnetic force, one of the four fundamental forces of nature. It influences the structure and behavior of atoms, the emission and absorption spectra of light, and the interactions between charged particles. Its precise value is critical for the accuracy of theoretical predictions in quantum mechanics and other fields of physics.
As of now, the value of the Fine Structure Constant cannot be derived from first principles. It is considered a fundamental constant of nature, meaning its value is determined experimentally. While various theories and models have attempted to explain its value, no universally accepted derivation has been achieved.
Current scientific evidence suggests that the Fine Structure Constant has remained constant over time. Various astronomical and laboratory measurements have been conducted to detect any potential variation, but so far, no significant changes have been observed. This constancy supports the stability of the physical laws governing the universe.
Several theories and hypotheses attempt to explain the Fine Structure Constant, including those involving higher dimensions, string theory, and varying physical constants. However, none of these theories have been proven or widely accepted in the scientific community. The Fine Structure Constant remains one of the unsolved mysteries of modern physics, and its exact origin and nature are still subjects of ongoing research.
