Unified Electroweak Interaction

weak charges closely related to electromagnetic
       charges, not actually small at very short
       distances weak interaction comparable to
       electromagnetic

difference in strength due to huge difference
       in mass of W and Z, very heavy,
       and massless photon

Next unification in progress
       1) electroweak with strong
        2) electroweak/strong with gravity
                      = string theory ...again, another Nobel prize for your generation
