Summary

Cover of the October 1920 issue of Popular Science magazine, painted by American illustrator Norman Rockwell. It depicts an inventor working on a perpetual motion machine. The device shown is a "mass leverage" device, where the spherical weights on the right have more leverage than those on the left, supposedly creating a perpetual rotation, but there are a greater number of weights to the left, balancing the device.

Popular Science (magazine) (also known as PopSci) is an American digital magazine carrying popular science content, which refers to articles for the general reader on science and technology subjects.
