Stephen Hawking is the world-famous physicist with a cameo in “The Simpsons on his CV”, but outside his academic field his work is little understood. To the public he is a tragic figure — a brilliant scientist and author of the 9 million-copy-selling “A Brief History of Time”, and yet confined to a wheelchair and almost completely paralysed. Hawking's major contribution to science has been to integrate the two great theories of 20th-century physics — Einstein's General Theory of Relativity and Quantum Mechanics. J.P. McEvoy and Oscar Zarate's brilliant graphic guide explores Hawking's life, the evolution of his work from his days as a student, and his breathtaking discoveries about where these fundamental laws break down or overlap, such as on the edge of a Black Hole or at the origin of the Universe itself.
is important to understand the notion of partial theories. For example, Newton’s Law of Gravitation is very accurate only when gravity is weak – and must be replaced by Einstein’s general relativity in strong gravitational fields. Similarly, relativity must be replaced by quantum mechanics when examining interactions on a microscopic scale, such as the big bang singularity, or at the edge and centre of a black hole.

Stephen Hawking is called a relativistic cosmologist. This means he studies the Universe as a whole (cosmologist) and uses mainly the theory of relativity (relativistic).
