Georg raised an interesting point when pointing out that Wikipedea is not the best or most reliable sorce for science research. I now realize that my science education is from a lot of sources; very few of them primary.I think I get the best stuff mostly from text books but also from popular science books, television, radio, periodicals, encyclopedea's, newspapers and, of course, the "Internet". Which of these do Last Worders prefer?

Do we all perceive color the same way ? for example do we all see the same color green or is the word green or red or blue just names to tag how we perceive those color. If I switched eyes with someone he might see the grass the same way as I perceive the sky but still call it green even though for me it would be blue.

The same goes for colorblind people (those unfortunate to mix up colors) if they were brought up seeing the grass as we would see it red. He would say green to everything red if we were able to see through his eyes. It would rely on education then.

Do I make sense ?
