Shanghai Science and Technology Museum

This guide to the Shanghai Science and Technology Museum takes you back to October 21, 2001, when the presidents of the United States and Russia met China's leader inside this building for an APEC summit, six weeks after the September 11 attacks. It follows how workers had raced to finish the conference halls while the exhibition floors behind them stood empty and unfinished, with robots not yet switched on. Look up at the great glass sphere at the center of the atrium as you listen, designed to evoke life rising from water.
