Cadiz Ranch
Essex, California, USA
34.494638, -115.500469

Cadiz Ranch in Essex, California is located in the middle of the Mojave Desert. The organic farm grows lemons, table grapes (dried and turned into raisins) and squash on more than 300 acres of irrigated desert. This is made possible by seven wells that pump 2,000 gallons of water per minute at all times from an underground aquifer - a layer of water-bearing permeable rock from which water can be extracted.

Smale’s paradox
In differential topology, Smale’s paradox states that it is possible to turn a sphere inside out in a three-dimensional space with possible self-intersections but without creating any crease, a process more commonly and historically called sphere eversion (eversion means “to turn inside out”). This is surprising, to those who understand regular homotopy, and is hence deemed a veridical paradox.

Images: The award winning computer animation Outside IN explains the amazing discover, made by Steve Smale in 1957, that a sphere can be turned inside out by means of smooth motions and self intersections, without cutting and pasting. It convincingly demonstrates how valuable vizualization can be in the communication of mathematics - Source & full size at Outsite In - geom.uiuc.edu.
