As I came across this image today while surfing net, my first reaction was a smile... :). It reminded me of a fact that is an exception in mathematics. I'm talking about the only curve discovered so far that can straighten things..., of course it's a smile :). But my recent hectic schedule made me forget that... and this image is giving me a new reason to come back to my idea and start smiling again. Nature tells us time by time that the ultimate goal of life is to make others happy by your presence and be yourself happy doing that.
