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?”
Science lesson for the day.
