2.38 = cosh² (1) = down quark/up quark mass ratio

0 = cosh^-1 (1) = photon and gluon mass

1.38 = sinh² (1) = higgs boson/z boson mass

0.88 = sinh^-1 (1) = w boson/z boson mass

1836 = 6pi⁵ = proton/electron mass

1/137 = fine structure constant

137 = 345 base 6 = 4pi³ + pi² + pi

137/60 = 5th term in the harmonic series (60 = 3 * 4 * 5)

1.00137 = neutron/proton mass

13.8 billion years = age of the universe
