    Unthinkable reason

    It’s September 1933. Physicist Paul Ehrenfest shoots and kills his disabled teenage son, Vassily, before turning the gun on himself.

    Ehrenfest, though gifted, has grappled with severe self-doubt and inferiority his whole life. He has tormented himself over his contributions to physics, which he considers inadequate.

    Later in life, his troubles descend into obsession, as he struggles to grasp the implications of the new theories being developed by physicists like Bohr and Heisenberg. At its core, quantum physics reveals a probabilistic, uncertain subatomic world that unsettles Ehrenfest’s belief in the harmony of nature. The cold mathematical approach of physicists like John von Neumann disturbs him, contradicting his mechanistic conception of the universe and plunging him into an existential and intellectual crisis.

    Ehrenfest experiences a brief period of euphoria, believing himself to have solved some enduring physics problems relating to turbulence.  But he soon realizes that he’s mistaken – his theory doesn’t work.

    Ehrenfest’s final slide into the abyss is prompted by the rise of Nazism in Germany. The spread of militaristic fervor horrifies him, as do eugenics and the cruel treatment of the mentally ill. Afraid for his vulnerable son Vassily’s future, and despondent for humanity and himself,  he decides death is the only solution.

    Chillingly, Ehrenfest emotionlessly boards a train to Amsterdam to carry out his violent plan.


    Ehrenfest’s horrific action might well prompt you to ask: What could possibly drive a father to murder his own child? The rest of the section seeks to unpack the turmoil leading to this tragedy. Intellectual concerns worry Ehrenfest deeply. The new mathematical theories of quantum physics seem somehow profoundly dehumanizing in their abstraction. We’re losing touch with physical intuition – somehow unmooring all of us from reality.

    This section establishes a central theme – a suggested link between pure reason and a kind of inhumanity. Ehrenfest experiences fear in witnessing impersonal forces beyond humanity – alien and uncaring. His story is a lens through which we’re invited to see the life of the central character, the mathematization and polymath John von Neumann.
