China's traditional top four inventions have taken on a new look. An exhibition recently held at the China Science and Technology Museum in Beijing showed that the old stalwarts of compass, papermak-ing, printing and gunpowder no longer hold pride place. While papermaking and print-ing remain but are merged into a single one,compass and gunpowder are replaced by bronze, silk and porcelain.
