Steam-engine
All began with a steam-engine of Nyyukomen. It Was used for water pumping in mines. Further known physicist J. Watt tried to improve device many years. For the end in 1782 the steam-engine became manageable and very useful.
Creation of a steam-engine stimulated development of many branches. To create steam-engines it's very necessary to have very qualitative materials and details. For this was created new inventions. In my opinion it became an integral part of the Victorian era.
