io9 On Quarks

io9 has a nice short article on quarks and how they, despite being quite light (in the case of the up and down quarks) are able to give us so much mass. It also comes with a video showing some weird visualizations of matter at different scales – from strings/branes (totally hypothetical) to living cells. The video looks much more like an artistic rendering inspired by physics than an accurate representation of the subatomic universe.
