C hange; change is the inevitable constant, a force of nature, driven, measured and observed by the laws of entropy on one hand and the magical forces of science, creativity, innovation, invention and engineering on the other. Time moves on second by second, hour by hour and year by year, forcing change upon us no matter what we try to slow or hold it back. Time is like the air we breathe and the rotation of the planet upon which we stand. Time moves on and, as it is truly said, 'time and tide wait for no man.'
