I just don't see why spanish is so popular, or even still tought in highschools when it is virtually useless.
Mind-boggling.

If they wern't so lazy, you wouldn't have all those groups of foriegners who set up shop in 45% of miami, or wherever.
The reasons that the "foreigners" set up shop in Miami, is because, as mostly Cubans, they have managed to flee Castro's "poor-causing" finger about 80 miles to Florida. You see, sometimes they have large families, and they can not take all of them across the water, so a few have to stay in Cuba, and continue to be poor. When you live right by Cuba, you can send things to Cuba, to support your loved ones, etc. Also, if you have just floated to another country with very little on your back, how would you plan on heading further north into the new land? And once they have a business, they see that they can make money where they are at, so why should they move?

My point was that just because you find the language useless, doesn't mean that it is useless. For example, I don't speak Polish, and I have no idea what products that Poland produces. For all I care, Poland could cease to exist, and I doubt it would have a huge impact on my life. The Poles could say the same thing about me, this individual. I'm sure that Polish is a very important language to them, otherwise they wouldn't speak it. Do I think that people should learn Polish? Yes, if they want to go to Poland, or interact with Polish people. Almost any language you speak can get you a good job in the military, if that's your cup of tea, as a translator.

A country doesn't have to make itself a part of your life to have their language taught in other countries.

I wonder how would you be able to explain the following:
1. Attractions between the atoms in each protein molecule make the polypeptide chain fold up into a rather rigid structure with a form appropriate to its particular function — for instance, with small pocket that is the attractive site where an enzyme catalyze a chemical reaction. Also, many functional proteins consist of a tight cluster of two or more polypeptides.
Many, many diagrams. Or with math, somehow...
