what's the science?　find the every possible way you can find and try to find wether there are some thing new? even you didn't find the new thins now, but that also just mean the ability of now not defined in the future.
so sciences said what's the problem of the things human doing? that's we think less things than we can.

in my opinion, sorry, i can't clear my opinion to express it clear. but anyway science is we want to reach, science is we want to use. so the only way we can do is explore, analyse, understand.
