It's getting to be that time of year again. The 2015 Nobel Prize in Physics will be announced this coming Tuesday morning (EU/US time). Based on past patterns, it looks like it could well be an astro prize. Dark matter/galaxy rotation curves anyone? Or extrasolar planets? (I still like Aharonov + Berry for geometric phases, perhaps with Thouless as well. However, it's unlikely that condensed matter will come around this year.)
On Wednesday, the chemistry prize will be awarded. There, I have no clue. Curious Wavefunction has a great write-up that you should read, though.
