What do you really know...
I stumbled on this quiz this morning - it was interesting.. I did ok:
It is good to know I am 'technologically useful' :) I liked the concept because it reminded me of a sci-fi book I read once (that I cannot for the life of me remember the title/author to - maybe someone reading this will have read the same book and can remind me, I really liked the story...) The concept of the book was that a very advanced space craft was found in the desert. When we got into it - there were some mummified remains, of humans. Basically, the earth was populated human wise by the survivors. But, if that were true and this ship was so advanced (meaning the people were technologically advanced) why didn't we get a big jump start in technology? The reasoning - you need a large critical mass of people in order to be as advanced as we are now. No one knows everything about anything - if you didn't have the mass of people building on each others work - it would all fall apart, rapidly.
It seems likes to be true, if you ask me.
