By the end of the 1800s, science and sophisticated realism reigned triumphant, having explained nearly the entire universe. But a few nagging problems remained, and in the early 1900s changes would blow apart the whole foundations of science and the most basic assumptions of what reality is.
The center of this revolution is Albert Einstein, a young physicist who in 1905 set the scientific world on its head with his theory of relativity. Further work in this area, along with the newborn science of quantum mechanics, reduced all of science up to that point down to size: pre-Einstein theories are now called "classical physics" -- the old way of looking at things.
