The telegraph, the telephone, the modern lightbulb, the assembly line, the automobile, the airplane, and the building of the transcontinental railroad in the United States are some of the most significant inventions of the Second Industrial Revolution.
The Second Industrial Revolution, often referred to as the Technological Revolution, took place between the late 19th and early 20th centuries and was characterized by a quick pace of scientific advancement, standardization, mass manufacturing, and industrialization. Before the Second Industrial Revolution began in 1870, the First Industrial Revolution, which concluded in the middle of the 19th century, was marked by a slowing in the development of significant inventions. The Second Industrial Revolution is typically dated between 1870 and 1914, despite the fact that some of its events can be linked to earlier advancements in manufacturing, including the emergence of the machine tool industry, the development of techniques for producing interchangeable parts, and the discovery of the Bessemer process to produce steel.
