some things about television technology. The fact 
is that television is  different from film and from 
still photos, and again from real life in one 
important way—it’s all made up of a lot of dots. 
And you, watching television, you do have to fit 
those dots together; you are making an effort, 
you are involved. He did have that perception. If he 
had stopped there it would be fine, but he got into 
other perceptions. He talked about the number of 
dots. He once said to me, “You know, if they would 
just pass a rule to change the number of pixels 
making up the screen it would improve education 
enormously.” Then he went into a long explanation 
about it which nobody quite followed or believed.
