Fine-Structure Constant 1/137 T-Shirt

Constant: alpha approx 1/137.035999177. Yes, we know. But nobody wants a 1/137.035999177 shirt, right?

The fine-structure constant measures the strength of the electromagnetic interaction between charged particles and light. Because it has no units, its near-1/137 value feels unusually bare: a pure number sitting inside atomic spectra and quantum electrodynamics.
