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