flexible eye lens focused by a fluid

Leave a comment

Fish_Eye The lens in our eye has a special designed feature called accommodation. That is, the lens changes shape, curvature, or focal length to bring images into focus. When we look at a far distant object the lens becomes thinner. For nearby objects the lens thickens and becomes rounder for clear vision. The flexibility is possible because tFocus_in_an_eye.jpghe lens is somewhat jellylike. Ciliary muscles around the edge of the lens control its shape. These muscles can become fatigued, and they recover when eyes are closed.

Dog inspired drying machines

dogshakingPerhaps you have stood near a wet dog as it dries by shaking its fur. Watch out! An impressive amount of water is thrown off in all directions. The shaking technique for furry creatures including mice, dogs, and bears is studied by researchers at the Georgia Institute of Technology in Atlanta. They find that larger animals tend to move their bodies at a frequency of 4-5 shakes per second. Mice and rats move more rapidly, up to 27 shakes per second. Whatever the size, each creature begins the shaking process with its head and then the process moves along the body. Mathematical formulas have been established for the animal shaking process based on size, nature of the fur, water surface tension, and other variables. The animals apparently know these technical details by instinct.
