Essays, these have nothing to do with boats

So what is this all about. Although I have an interest in boats, it so happens that I know quite a bit about other things. I have interests in science, history, economics, politics etc. These pages are about me putting some thoughts down on paper, do it once and then move on. These essays are totally optional reading, please only follow the links if you feel that you might be interested
