Where Is The Frog?: Something To Think About

So, where is the frog?

Somewhere there's a frog. Can you find it?

Camouflage creates its own kind of illusion.  Nature thrives on it, and optical illusions often befuddle humans.

S. Tolansky, a former Professor of Physics at the University of London, wrote a small treatise dealing with visual illusions.  And he argues that camouflage is a practical use of optical illusions.  Camouflage is used by animals and plants primarily as a means of protection from predators and by humans for warfare.  But all illusions are dependent on the health of the eye;  severe astigmatism can destroy the illusion featured below.  Yet, it is well to remember that things are not always what they seem!:oi-1

About Robert M. Weiss
From an early age, I've taken great pleasure in reading. Also, I learned to play my 78 player when I was quite young, and enjoyed listening to musicals and classical music. I remember sitting on the floor, and following the text and pictures of record readers, which were popular in the 1940s and 50s. My favorites were the Bozo and Disney albums. I also enjoyed watching the slow spinning of 16s as they spun out tales of adventure. I have always been attracted by rivers, and I love to sit on a boulder with my feet in the water, gazing into the mysteries of swirling currents. I especially like inner tubing on the Rogue River in Southern Oregon. Since my early youth, I've been interested in collecting minerals, which have taught me about the wonderful possibilities in colors and forms. Sometimes I try to imagine what the ancient Greeks must have felt when they began to discover physical laws in nature. I also remember that I had a special passion for numbers, and used to construct them out of stones. After teaching Russian for several years, I became a writer, interviewer, editor, and translator. I continue to delight in form, and am a problem solver at heart.
