This number results from applying a quantum state’s ket to its corresponding bra. QED is an abelian gauge theory that is described by a unitary group of this degree. Vector bosons like gluons and photons (10[1])must have spins equal to this number. (10[4])To obey the Born rule, the integral of the product of the (-5[1])wavefunction and its complex conjugate must equal this number. The Lyman series corresponds to setting n_1 (“n-sub-one”) equal to this number in the Rydberg formula, which describes an atom with this many protons. This number is (10[1])the atomic number of the only element with (10[1])analytic solutions. For 10 points, give this number of protons found in a hydrogen (10[1])atom. ■END■ (10[4]0[1])
