DESIGN











Snow is no match for smart design.

Hiking over several feet of snow becomes possible with some clever physics and nature-inspired design.

The caduceus is used as a medical logo, but that’s not its original meaning.

This ancient symbol, also called the Staff of Hermes, depicts two snakes intertwining around a stick that is capped by wings. It’s used as a medical logo, but for almost all its roughly 5000-year history, the caduceus had nothing to do with medicine.
