When Pythagoras invented a new way to make calculations with triangles, there was not yet an European Patent Organization. Bad luck, because everybody knows that patents stimulate innovation. Pythagoras invested much time in contemplation. Now, anyone could use this new mathemathical method for free. How could others be stimulated to make the same investment for no financial benefit?
