A German-born physicist offered startling new ideas on space, time, energy, and matter. Scientists had found that light travels at exactly the same speed no matter what direction it moves in relation to earth
Theory of relativity
In 1905, Einstein theorized that while the speed of light is constant, other things that seem constant, such as space and time, are not. Space and time can change when measured relative to an object moving near the speed of light—about 186,000 miles per second.
Relative motion is the key to Einstein’s idea.
An Austrian physician who treated patients with psychological problems. From his experiences, he constructed a theory about the human mind. He believed that much of human behavior is irrational, or beyond reason. He called the irrational part of the mind the unconscious. In the unconscious, a number of drives existed, especially pleasure-seeking drives, of which the conscious mind was unaware. Freud’s ideas weakened faith in reason.

Why were the ideas of Einstein and Freud revolutionary?
Einstein developed a new theory of Relativity of uncertainty and relativity replaced Isaac Newton’s comforting belief of a world of constants operating according to absolute laws of motion and gravity. Freud’s theories about the universe were new and challenged the Enlightenment or age of Reason theories when he that much of human behavior is irrational or beyond reason.
How did literature in the 1920s reflect the uncertainty of the period?
The brutality of World War I caused philosophers and writers to question accepted ideas about reason and progress.
