Time and time again, Albert Einstein has been counted among the most important people of the 20th century. As we look to understand the true nature of the universe with technological tools that weren't even dreamed of in his lifetime, Einstein's formulae remain our best key for decoding it. Einstein: A Relative History explores both the scientist's work and his private life. It also features a fascinating plain-language exploration of his famous thought experiments, which reveal how this extraordinary thinker visualised complex concepts. Accessible to all adults interested in the man, his life, and his work.
