Using an atom interferometer method, we measure the recoil velocity of cesium due to the coherent scattering of a photon. This measurement is used to obtain a preliminary value of/MCsand the fine structure constant, α, with an uncertaintyΔα/α = 7.3 × 109....
Scientists have most accurately measured the fine-structure constant, the number that essentially shapes the universe.

A team in Paris has made the most precise measurement yet of the fine-structure constant, killing hopes for a new force of nature: “Physicists Nail Down the ‘Magic Number’ That Shapes the Universe.” [TotH to MK] * George Gamow ### As we ponder precision, we might spare a thought...
