“The fine-structure constant is ubiquitous throughout physics. I’ve already noted its connection to the electromagnetic interaction. In atomic physics, the binding energy, fine-structure splitting,…

— Gerald Gabrielse

“The theoretical determination of the fine structure constant is certainly the most important of the unsolved problems of modern physics.”

— Wolfgang Pauli

“To calculate 'the' fine structure constant, 1/137, we would need a realistic model of just about everything, and this we do not have. In…

— Steven Weinberg

“Let us begin with the fine-structure constant. ... The fine-structure constant is really the ratio of two natural units or atoms of action. ...…

— Arthur Stanley Eddington

“Even a good, inveterate atheist like physicist Richard Feynman once said of the fine structure constant, “All good theoretical physicists put this number up…

— Sam Kean

“One hundred thirty-seven is the inverse of something called the fine-structure constant. ...The most remarkable thing about this remarkable number is that it is…

— Leon M. Lederman

“The strength of the familiar electromagnetic force between two electrons, for example, is expressed in physics in terms of a constant known as the…

— Mario Livio

There are considerable mysteries surrounding the strange values that Nature's actual particles have for their mass and charge. For example, there is the unexplained…

— Roger Penrose

“The apparent strengths of the forces in any field theory depend on two kinds of numerical parameter: the masses (if any) of the particles…

— Steven Weinberg

“In the context of physics, 137 is equal to the integer part of the inverse of the fine structure constant ... The fine structure…

“There is a most profound and beautiful question associated with the observed coupling constant, e - the amplitude for a real electron to emit…
