Stephen Hawking

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.

    time, the imaginary component does not vanish at the big bang and the theory is thus useful at the singularity. Standard quantum mechanical procedures are then used to arrive at a wave function for the Universe.
    COMPLEX TIME NEAR THE BIG BANG SINGULARITY.

    But what are standard quantum mechanical procedures? For that matter, what is a wave function?

    HAWKING’S NEW PICTURE, A BLACK HOLE IS NOT A BOTTOMLESS PIT BUT A PHYSICAL OBJECT. A BLACK HOLE IS NOT BLACK BUT EMITS THERMAL RADIATION AT A CERTAIN DEFINITE TEMPERATURE.

    EACH BLACK – HOLE LAW, IN FACT, TURNED OUT TO BE IDENTICAL TO A THERMODYNAMIC LAW, IF ONE ONLY REPLACED THE PHRASE “BLACK HOLE’ SURFACE AREA” BY “ENTROPY,” AND THE PHRASE “BLACK HOLE’ SURFACE GRAVITY” BY TEMPERATURE.
    THE COINCIDENCES WERE PILING UP.
