No. Many of you *think* you know that. It's simply not true. Glass is a solid. It doesn't flow on human time scales. windows that are thicker at one end than others are a result of primitive glass rolling techniques, that resulted in non-uniform thicknesses. If you actually look at windows, you'll find that the thick side is as often on top as on the bottom, and sometimes on one side, or in the middle.
