What does the above symbol look like to you? A sad smiley, do you say? But it can mean a lot of other things, can’t it? Like say, a colon followed by an opening bracket? Or better still, two wires coming out of the plane of the paper, oops, screen, just a little left to a concave lens. Of course, you could see the same lens as a convex lens as well, if you are one of those out of the box thinkers, who can see rays of light coming from the left instead of the right (what most people would otherwise do)! And can’t the symbol above also depict a guy carrying a bowl over his head, and they guy is in dark, and only his eyes and the silvery bowl are visible? Why are the eyes visible, do you ask, if it’s dark? Well, he could have had an eye transplant surgery some time back, when he lost his eyes, and insisted on acquiring a new pair that had been donated by his dying cat!
