What are some clever designs in various fields and how do they work?

[Stewart Snider]

Hi,

I'm new here and joined just to get some curiosity questions answered. Not educated in physics or engineering, but I've always been curious about how stuff works and I have a deep affection for clever design in most any field. I posted a basic question in one of the forums today on something I've wondered about for years.

Thanks to the creators of this forum. I expect to be here pretty often.
