Just technical enough to please the nerd but with enough story to make the prose smooth and enjoyable. We're used to hand waving explanations of planetary formation from a disc of dust and gas, but Tasker shows how there's not long in planetary timescales for this to happen, and why it's really distinctly difficult for a cloud of dust grains to do anything more than bounce off each other, rather than clump together to form a planet.
