Por falar em escalas…

… no artigo Huygens Sends Images of Titan, da National Geographic News, pode ler-se: Titan is sitting up there perking away as kind of a planet-scale chemistry lab doing a lot of the stuff that was going on in the Earth’s atmosphere four billion years ago. Passamos do “lab-on-a-chip” para o “planet-scale-chemistry-lab”. Temos mesmo de rever as nossas escalas…. Ah, o artigo é excelente, vale a pena ler o resto.
