Time and again some portions of my articles have been removed as "copyrighted"!!!
Please do not do that again: I indeed pasted it ready-made; however, I pasted it from my own article (
http://www.supermemo.com/articles/genius.htm#Steve%20Wozniak).
Please feel free to expand upon this text, but I would appreciate if you would leave this note intact.
One reason is that I would not like anyone ever think that I steal material from
Wikipedia to write my own articles!
I just thought this would be a nice contribution. --
