Mathematisch-Physikalischer Salon
The Mathematisch-Physikalischer Salon in Dresden's Zwinger contains a nice collection of historic globes, scientific instruments, astronomical clocks and watches. There are gigantic concave mirrors by Ehrenfried Walther von Tschirnhaus (1651-1708) and pictures of cannonball trajectories which are not *exactly* supported by any law of motion I trust. ;-)
