I have to thank Thomas (who was the inspiration for this thread) who posted a link whherein Lincoln was attributed to have presented the Gettysburg Address as a powerpoint presentation
LINCOLNS GETTYSBURG ADDRESS IN POWERPOINT
It would be funny if it werent sad how a tool like powerpoint has been adopted and now serves a purpose to stifle communication and creativity.
Theres a fellow from Yale,Edward Tufte, whos been called "The Leonardo of data" Hes the author of a book
The Visual Display of Information, Visualizing Information,and
Visual Explanations: Images and Quantities, Evidence, and Narrative
His main message is "Good Content is Critical for Good Presentations, but Poor Display of the Information, Kills the Presentation"
HEs been a major critic of the valuelessness of Powerpoint when it comes to presenting math and science data. An average graph in SCience has about one thousand data points in it. An average graph in the Wall STreet Jounal, a hundred. A typical Powerpoint slide has 12 data points according to Tuftes.
Powerpoint forces a lame structure on the presentation, a structure that causes a loss of clarity. An example was the Powerpoint presentation that NASA used to analyze the
Columbia disaster.All the conclusions were lost in the oversimplification that Powerpoint forced to the presentation. Noone could glean what caused the disaster , so rteporters pretty much dragged bullet points and wrote around them , with often comical results.
Powerpoint reduces the content of a presentation to its lowest common denominator. Thats why the Norvig take on the Gettysburg Address is a worthhy display of how a great speech could have been turned to some beurocratic garbage.
Tufte does say that theres a good use of Powerpoint,as a slide projector of low res pictures that (he says) should be accompanied by paper handouts that explain the images.
