No research no ipod nano.
I think what is most interesting about today’s Nobel prize in physics is how quickly the discovery of a new effect, giant magneto-resistance, led to real devices including the iPod. From the totally unknown to the utterly familiar in less than twenty years. The world really is speeding up.
The Nobel Prize Foundation has a very nice write-up of giant magneto-resistance and its applications.
Thanks to the Marginal Revolution, a very interesting economics blog. Seriously, interesting economics blog exist.
