Tipping Point 3 is PowerPoint.
PowerPoint has caused a revolution of teaching and presenting.
It is much prettier, and livelier than the traditional
chalkboard. The major power
of PowerPoint is just being found. When we taught with a chalk board
at the end of the lecture we would erase the board with our lectures
falling to the fall. PowerPoint on
the web allows us to re-use our lectures. In fact it allows
anyone to reuse our lectures.
