The few major advancements in science and technology was the Bessemer Process, dynamite, light bulb, and products with interchangeable parts. The Bessemer Process made steel become a major material because it made steel more light, durable, and cheaper. The dynamite was a more safer explosive used doing warfare. The light bulb allowed for business to be lit up after dark. The interchangeable parts created less work for one person, efficiency, and affordable factory goods.
