A. Einstein signed "Easy Lessons in Einstein" Book 1921. Easy Lessons in Einstein, A Discussion of the More Intelligible Fearures of The Theory of Relativity is a book authored by Edward E. Slosson is considered the first book to present Einsteins Theorys in layman's terms. Although his attempts to unify differing theories of gravity and relativity were discounted after his death, many now believe that he has since been vindicated with new discoveries, including the "strong force" of particle physics. Albert Einstein was a German mathematician and physicist who developed the special and general theories of relativity. In 1921, he won the Nobel Prize for physics for his explanation of the photoelectric effect. In the following decade, he immigrated to the U.S. after being targeted by the German Nazi Party. His work also had a major impact on the development of atomic energy. In his later years, Einstein focused on unified field theory. With his passion for inquiry, Einstein is generally considered the most influential physicist of the 20th century.
