The experiments in this book are derived from experiments that Thomas Edison performed himself. As the young scientist works out the experiments he will become familiar with some of the basic scientific principles underlying such great inventions and discoveries as the incandescent lamp, the carbon button, the fuse, and wireless. He can build a phonograph that resembles Edison’s first phonograph or they can make a simplified version of the electric pen, which was the forerunner of the modern mimeograph machine. There are chapters on insulation, the quadruplex, the telespecan, and the Edison Effect. There is also a brief biography.
