Garrett Morgan invented an early version of the traffic light using a simple design that included a system of signals to control traffic flow at intersections. His invention featured three positions: one for stop, one for go, and a third for an all-directional stop, allowing pedestrians to cross safely. Morgan's traffic signal utilized mechanical components and was operated manually before the development of electric signals. His innovative design significantly improved road safety and paved the way for modern traffic lights.
A lot of inventions came from the country of France. Some inventions include the battery, bicycle, braille, guillotine, electric iron, and mayonnaise.
This depends on which scientific invention you are referring to. I would say that yes, many inventions make us happy.
