Teachers like this old-fashioned, quirky and energetic guy are why students become interested in science. Sadly, these kinds of teachers are rare. He reminds me of the NASA guy(also quirky) who comes on public t.v. to tell us about the objects in the night sky.

I couldn't agree more. All we do in school now during chemistry or physics is copy out of text books with the very occasional experiment which is just so boring.

I don't agree that a wedge is simply an inclined plane, although all wedges are inclined planes. Use a knife to cut something and yes, its function as an inclined plane redirects downward force partly into sideways force, pushing the two pieces apart. But the cutting itself is not a property of inclined planes. A wedge also concentrates force towards its thin end, to a small contact area which translates to a very large force per unit of surface area. This is a function specific to wedges.
