SciGuy is giving away books every day from now until the day after Christmas - his Christmas present to his blog's valued and faithful readers.
The first offering is a shrink-wrapped, hard-cover book titled Microscosmos that contains 203 pictures from a scanning electron microscope. We're talking about magnifications from 20X to 22 millionX. It's been described variously as visually stunning and visually arresting.
