In a cultural group in the 19th and 20th the western cultures started becoming more modern with technology, communication and military(). This modernization had given the western culture more political power and economic success in other cultures().
How did innovation and technology change life in the 19th century? Answer.
Even the most important inventions of the 19th century that were not simply applications of steam or electrical power, such as the recording technologies of the photograph and the phonograph, contributed to this because they made the past available to the present .
History of technology - The Industrial Revolution (–): The term Industrial Revolution, like similar historical concepts, is more convenient than precise. It is convenient because history requires division into periods for purposes of understanding and instruction and because there were sufficient innovations at the turn of the 18th and 19th .
Most important inventions of the 19th century: in pictures.
The first steam locomotive. Cornish steam pioneer Richard Trevithick was the first to develop a high-pressure engine capable of. Late Nineteenth Century Inventors and Inventions: While we often imagine that the twentieth century was the era in which the greatest advances in technology and science occurred, many often overlook the remarkable advances that came out of the preceding century?advances which in themselves were equally as astonishing in their era as those of the twentieth century were for us.
