The period 1989-2000 provided a huge yield of precise electroweak data from the LEP and SLC experiments. Many analyses of these data are now complete, but others, particularly of the full LEP-2 data samples, continue. The main electroweak…

The phenomenological evidence for electroweak corrections in the Standard Model, both at very low energies and the $Z^0$ scale, is discussed. In particular, we review a simple but sharp argument for the presence of Electroweak Bosonic…
The 1999 precision electroweak data from LEP and SLC persist in showing some slight discrepancies from the assumed standard model, mostly regarding $b$ and $c$ quarks. We show how their mixing with exotic heavy quarks could result in a more…
