Physics Again!

After a few years of applied mathematics, better known as Computer "Science", I expect Physics to become popular once again. Besides being a physicist, I believe this, because at some point, we will need hardware, which behavior can only be understood with Physics. Right now there is a spacecraft, the size of a Mini Cooper, in its way to the surface of Mars. It will be powered by a chemical that has all but disappeared from the Solar System. Plutonium has a lifetime of twenty thousand years, the Solar System was formed more than four billion years ago. All the primordial plutonium, baked for us in some far away star, which exploded as a supernova, is gone by now.

The only reason this rover will move around on the surface of Mars, if it lands properly, is that we know Fundamental Physics.
