We compute observables of the critical 3d Ising model to high precision by applying the numerical conformal bootstrap to mixed correlators of the leading scalar operators sigma and & varepsilon;, and the stress tensor T mu nu. We obtain new precise determinations of scaling dimensions (triangle sigma, triangle & varepsilon;) = (0.518148806(24), 1.41262528(29)) as well as OPE coefficients involving sigma, & varepsilon;, and T mu nu. We also describe several improvements made along the way to algorithms and software tools for the numerical bootstrap.
