Anyone who reads Giz with any sort of regularity knows that we don't try to hide our affinity for toys. But for some brainiacs, toys like the Etch-a-Sketch aren't just diversions, they're launching pads for important scientific discoveries.
Scientific American rounds up 4 instances in which tiny toys led to some big answers, including the story of a nanoscale transistor that was invented by a physics professor who had the Etch-a-Sketch on the mind.
Head over to Scientific American to see the rest of the lot. Just don't blame me if you find yourself unable to build a LEGO set without thinking of "Directional Locking and the Role of Irreversible Interactions in Deterministic Hydrodynamics Separations in Microfluidic Devices."
