    Just How Small is an Atom?

    A fantastic new video from the TEDEd project. By the way, a grapefruit is the same as an Earth filled with blueberries.

    It does a fantastic job detailing the misconceptions that abound in basic science books. Atoms are hard to get your mind around, even though your mind is made of them.

    Previously: I answer the question: “If atoms are mostly empty space, why don’t we fall through the floor?”
