I will present recent advances in computing nucleon structure from first principles on a lattice and discuss their connection to current experiments. Quantum Chromodynamics is generally accepted as the fundamental theory of hadron constituents, quarks and gluons. However, making reliable predictions from it requires numerical methods. After decades of development of theory and computing, lattice QCD is now capable of calculations with realistic parameters. Calculating structure of the proton and the neutron is critical to both validating lattice QCD methods and providing theory counterpart to modern experimental efforts to study hadron structure, with proton charge radius, electromagnetic form factors, and proton spin origin being the most notable. In addition, nucleons and nuclei are natural laboratories to search for deviations from the Standard Model. Sensitivity of such detectors to new physics can often be evaluated only on a lattice.
