The AAA emblem was adopted by the Board of Directors in 1947.
The design incorporates the mathematical symbol for infinity entwined about a five-pointedˆàstar.
The letter symbols within the star are those of the astrophysicist:ˆàEˆàrepresents energy;ˆàCˆàthe velocity of light; the Greek letters nu (¾) and lambda (¾¨) signify respectively the frequency and wavelength of light; andˆàh, the empirical mathematical constant of Max Planck’s quantum theory.
