Well education is perhaps the most efficient way to make a society move onward or to create individual success. Public education has always played a key role in a nations success, I can speak from the experience of my own country Sweden that went from being a very poor country at the beginning of the 20th century. But with the help of education and the use of efficient government policies manage to become the wealthy country it is today.

Although I can't say if the best way for the United states would be to socialize education given many Americans predisposed dislike of centralization, I do think that an free education is the best way to take an country or a proportion of the country from poverty.

Well, this is a subjective idea and only depends on each persons definition of "the end" and "okay". But yeah for me it makes sense :P

Well the same thing applies to evolution, which is has a key role in modern biology. And with the Lenski experiments we have actually observed evolution in E.coli bacteria. And we have observed evidence for evolution happening in the past.

Well basically all colors are different wavelengths of light, and describing a color to a color-blind person is quite like imagining to see radioactivity or microwaves. It's a kind of pointless ordeal that perhaps never will get an answer.

But we could try to describe a color from it's "feelings" and by that I mean we have certain predisposed values towards different colors. Red for example is often instinctively connected to the feeling of danger and will get our attention (Which is used by advertising companies) but your friend will not get an real idea of the color that way either. What's left is an philosophical question that I don't believe will get an answer. Although I long for the day I can be proved wrong (hopefully today)
