Re: [Phys-L] Power Point's Huge Waste of Paper
There are very interesting comments in light of the reference to Edward Tufte
earlier. He would agree, saying that ppt are a low density way to transmitting
information. His approach, as I understand it, would be hand out a printed
page much richer than the ppt, allow people to have time to read it, and then
lead a presentation build on the ideas in the page.
