Key takeaways

  • The Tao of Physics belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect The Tao of Physics to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of The Tao of Physics from memory before moving on to harder problems.

Reference excerpt

The Tao of Physics: An Exploration of the Parallels Between Modern Physics and Eastern Mysticism is a 1975 book by physicist Fritjof Capra. A bestseller in the United States, it has been translated into 23 languages. Capra summarized his motivation for writing the book: "Science does not need mysticism and mysticism does not need science. But man needs both."

Origin According to the preface of the first edition, reprinted in subsequent editions, Capra struggled to reconcile theoretical physics and Eastern mysticism and was at first "helped on my way by 'power plants'" or psychedelics, with the first experience "so overwhelming that I burst into tears, at the same time, not unlike Castaneda, pouring out my impressions to a piece of paper". (p. 12, 4th ed.) Capra later discussed his ideas with Werner Heisenberg in 1972, as he mentioned in the following interview excerpt:

I had several discussions with Heisenberg. I lived in England then [circa 1972], and I visited him several times in Munich and showed him the whole manuscript chapter by chapter. He was very interested and very open, and he told me something that I think is not known publicly because he never published it. He said that he was well aware of these parallels. While he was working on quantum theory he went to India to lecture and was a guest of Tagore. He talked a lot with Tagore about Indian philosophy. Heisenberg told me that these talks had helped him a lot with his work in physics, because they showed him that all these new ideas in quantum physics were in fact not all that crazy. He realized there was, in fact, a whole culture that subscribed to very similar ideas. Heisenberg said that this was a great help for him. Niels Bohr had a similar experience when he went to China. Bohr adopted the yin yang symbol as part of his coat of arms when he was knighted in 1947; it is claimed in the book that it was a result of orientalist influences. The Tao of Physics was followed by other books of the same genre like The Hidden Connection, The Turning Point and The Web of Life in which Capra extended the argument of how Eastern mysticism and scientific findings of today relate, and how Eastern mysticism might also have the linguistic and philosophical tools required to undertake to some of the biggest scientific challenges remaining.

Afterword to the third edition In the afterword to the third edition (published in 1982, pp 360–368 of the 1991 edition) Capra offers six suggestions for a new paradigm in science.

Consider the part and the whole as more symmetrically conditioning one another. Replace thinking in terms of structure with thinking in terms of process. Replace ‘objective science’ with ‘epistemic science’, where the approach to decide what counts as knowledge adapts to the subject studied. Replace the idea of knowledge as buildings based on foundations with an idea of knowledge as networks. Abandon the quest for truth with a quest for better approximations. Abandon the ideas of domination of nature with one of cooperation and nonviolence. Capra reconnects this new paradigm to the theories of living and self-organizing systems that has emerged from cybernetics. Here he quotes Ilya Prigogine, Gregory Bateson, Humberto Maturana and Francisco Varela (p. 372 of the 1991 edition).

Acclaim and criticism According to Capra, Werner Heisenberg was in agreement with the main idea of the book:I showed the manuscript to him chapter by chapter, briefly summarizing the content of each chapter and emphasizing especially the topics related to his own work. Heisenberg was most interested in the entire manuscript and very open to hearing my ideas. I told him that I saw two basic themes running through all the theories of modern physics, which were also the two basic themes of all mystical traditions-the fundamental interrelatedness and interdependence of all phenomena and the intrinsically dynamic nature of reality. Heisenberg agreed with me as far as physics was concerned and he also told me that he was well aware of the emphasis on interconnectedness in Eastern thought. However, he had been unaware of the dynamic aspect of the Eastern world view and was intrigued when I showed him with numerous examples from my manuscript that the principal Sanskrit terms used in Hindu and Buddhist philosophy-brahman, rta, lila, karma, samsara, etc.-had dynamic connotations. At the end of my rather long presentation of the manuscript Heisenberg said simply: "Basically, I am in complete agreement with you."The book was a best-seller in the United States. It received a positive review from New York magazine: A brilliant best-seller ... Lucidly analyzes the tenets of Hinduism, Buddhism, and Taoism to show their striking parallels with the latest discoveries in cyclotrons. Victor N. Mansfield, a professor of physics and astronomy at Colgate University who wrote many papers and books of his own connecting physics to Buddhism and also to Jungian psychology, complimented The Tao of Physics in Physics Today:

Fritjof Capra, in The Tao of Physics, seeks ... an integration of the mathematical world view of modern physics and the mystical visions of Buddha and Krishna. Where others have failed miserably in trying to unite these seemingly different world views, Capra, a high-energy theorist, has succeeded admirably. I strongly recommend the book to both layman and scientist. However, it is not without its critics. Jeremy Bernstein, a professor of physics at the Stevens Institute of Technology, chastised The Tao of Physics:

At the heart of the matter is Mr. Capra's methodology – his use of what seem to me to be accidental similarities of language as if these were somehow evidence of deeply rooted connections. Thus I agree with Capra when he writes, "Science does not need mysticism and mysticism does not need science but man needs both." What no one needs, in my opinion, is this superficial and profoundly misleading book. Leon M. Lederman, a Nobel Prize-winning physicist and current Director Emeritus of Fermilab, criticized both The Tao of Physics and Gary Zukav's The Dancing Wu Li Masters in his 1993 book The God Particle: If the Universe Is the Answer, What Is the Question?

Worked examples

Example 1 — a first encounter with The Tao of Physics

Start with the simplest possible case. Write down what The Tao of Physics claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to The Tao of Physics before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about The Tao of Physics ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of The Tao of Physics

In research
The Tao of Physics appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses The Tao of Physics in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
The Tao of Physics is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1975 English-language non-fiction books, 1975 non-fiction books, American non-fiction books, so understanding it makes those chapters shorter.
In everyday life
Look for The Tao of Physics outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
