Like any scientist, I often measure my observations of the world in terms of solutions.
Nature is no exception.
I am always observing systems in nature to wonder how their workings, interactions and natural designs can be applied to sceintific problems. When I watch conventional space probes being launched, I see elephants. Someday I'd like to see bumble bees. Of course this isn't literal, elephants and bumble bees are models from nature that I believe relate to the physics of propulsion and movement of mass. Current spacecraft are built with most of their mass and weight devoted to structure, like elephants with their big, solid bones.
