Go back to 1900: That industry was chemistry. People had chemistry sets. In the 1930s, it was the rise of physics and physicists. They build on each other. Chemists laid the experimental understanding for the physicists to build their theories. It was three physicists who invented the transistor in 1947. That started the information revolution.
