Et tu, Brute?
Why are you talking about practical applications?
One of the awesomeness things about the Nobel Committee is that their mandate is that it be given for either discovery or
invention, and yet they've pretty much ignored
the latter in most cases.
I fully approve. Discoveries are
more important than inventions. Last year's nobel prize (IMO) was the most important discovery in my lifetime (of course I am biased towards astrophysics).
