That's because of the huge changes brought by the invention of processes to mass produce steel in the 1860s. Henry Bessemer created the modern age. When cheap steel became available there was a whole new way of manufacturing everything.

Besides that, there were many important scientific discoveries. For instance, the concept of sanitation started by Florence Nightingale increased life expectation by twenty years during that period.
