Ideas and Opinions is the definitive collection of Einstein's writing, including scientific writings that are the foundation for modern physics and of our modern world, extracts from his speeches on subjects as diverse as atomic war, religion and human rights and letters that show the personal side of one of the world's greatest, and most public, intellectuals. Einstein's writings re-defined mankind's ideas about the universe. His theory of relativity changed how we think of space and time while his proposal that energy and matter are interchangeable, summed up as E = mc², became the most famous mathematical equation in history.
