It took Christopher Columbus over eight weeks to cross the Atlantic. Nowadays, we can do it in less than eight hours in a jumbo jet. What would Columbus or Archimedes have made of it? Well, it doesn’t mean they were less intelligent than you or me. They were probably more intelligent. And maybe all this progress that modern man seems to be making is partly an illusion. Perhaps there are even things we can learn from the science and technology of ancient times. Take the city, for example. Cities seem so much the product of modern technology and yet, in fact, they are one of the most ancient of all inventions.
