Innovation begins with public knowledge, often scientific or mathematical discoveries that sometimes do not seem to have any practical value.   Imaginary numbers, general equations of electromagnetism, the Second Law of Thermodynamics, Brownian motion, E=mc**2, the structure of DNA, the conductivity of solids, quantum superposition, etc.   Some  scientists and inventors begin to see possible applications of this scientific knowledge.   In the 20 th century, they are often funded by ...
