Two very different books — Daniel Keown’s The Spark in the Machine and Richard Feynman’s QED — begin from the same fascinating premise: everything is electric.
In QED, Feynman strips physics to its bones. The world, he argues, is built from the interactions of charged particles exchanging photons. Light is not mystical illumination; it is an electromagnetic messenger. Electrons repel and attract by trading quanta of energy. The solidity of matter, the chemistry of life, the warmth of the sun — all reduce to patterns of charge and exchange. Feynman’s genius is not just in explaining quantum electrodynamics, but in making it feel...solid. Redwood trees, rail cars, rhinoceroses, refrigerators, rainforests--they are all mostly empty space filled with colliding, transforming particles--look deep enough and you find electrical interaction.
Keown, approaching from a different direction, proposes that traditional Chinese acupuncture maps onto bioelectric circuitry within the human body. He argues that meridians correspond to fascial planes and conductive pathways, and that health depends on electrical coherence. Where Feynman speaks of photons and amplitudes, Keown speaks of voltage gradients and tissue conductivity. But both imagine the body not as a hydraulic system, but as a dynamic electrical field.
The commonality is not proof; it is perspective.
Both authors reject the purely mechanical metaphor of the body and the universe. In Feynman’s account, what appears solid is mostly empty space structured by electromagnetic force. In Keown’s account, what appears anatomical is animated by charge distribution and electrical signaling. The difference lies in rigor and scope. Feynman’s work rests on experimentally verified mathematics that predicts results to extraordinary precision. Keown’s framework is more interpretive, attempting to reconcile ancient medical practice with modern bioelectric research.
Yet the philosophical overlap is striking. Both books challenge the naive intuition that matter is inert. Instead, they suggest that structure arises from invisible interaction. Energy precedes form. Pattern precedes substance.
The divergence is equally important. Feynman is relentlessly empirical. His photons either match experiment or they don’t. Keown operates at the frontier between hypothesis and demonstration, where metaphor risks outrunning measurement. That tension does not invalidate the comparison; it sharpens it.
If QED teaches that the universe is electrical at its deepest level, The Spark in the Machine asks whether that same principle scales into biology in ways medicine has only begun to grasp. One book explains the microcosm of fundamental forces. The other speculates about the macrocosm of living systems.
They do not belong in the same category of certainty. But they do belong in the same intellectual conversation.
Both remind us that the world — and the body — may be less mechanical than we were taught, and more like a symphony of charge.
One represents the gold standard of physical theory. The other explores whether life’s complexity may also be grounded in electrical patterning. The books are inseparable in my mind, entwined and enmeshed in the complex reality I live in and hope to some degree to understand.
