Niels Bohr, a pioneer of quantum mechanics, chose the Taoist yin-yang symbol for his coat of arms.
He saw that the polarized states of particles, for example, complement each other the way the two extremes of yin and yang create a balance in the Taoist understanding of the universe. Bohr spoke of the unity of opposites and contradictions in nature.

Many concepts in ancient Chinese science correspond to ideas physicists have only formed in the past century or so. Here’s a simple look at a few such concepts.
1. Eight Trigrams and Particle Arrangements

The eight trigrams are presented in the classic Chinese text “I Ching” (“Book of Changes”), an important and fundamental work in Chinese history. The trigrams each represent essential principles of reality and they are arranged in an octagonal pattern based on the relationships and interactions between them.
In his 1975 book, “The Tao of Physics,” physicist Fritjof Capra wrote that this octagonal pattern is similar in certain ways to the meson octet “in which particles and antiparticles occupy opposite places.” The important part for Capra is that the concept of structure and change is similar.
“Both modern physics and ancient Chinese thought consider change and transformation as the primary aspect of nature, and see the structures and symmetries generated by the changes as secondary,” he wrote.
2. The Book of Changes and the Elusive Theory of Everything
Modern physics rests on the two pillars of general relativity and quantum mechanics. The problem is the two are contradictory.
In 1999, Brian Greene wrote in his Pulitzer Prize-nominated book “The Elegant Universe”: “As they are both currently formulated, general relativity and quantum mechanics cannot both be right. The two theories underlying the tremendous progress of physics during the last hundred years—progress that has explained the expansion of the heavens and the fundamental structure of matter—are mutually incompatible.”
Relativity works well for understanding the universe on the largest scale, that of stars, galaxies, et cetera. Quantum mechanics works well for understanding the universe on the smallest scale, that of atoms, subatomic particles, et cetera. Scientists search for the so-called “theory of everything,” to cover both.
String theory attempts to do this. In simplified terms, string theory conceives of the universe as strings rather than separate points. An electron, for example, would not be a point, but rather a part of a string. If the string oscillates one way, it appears to be an electron, if it oscillates another way, it could appear to be a photon or a quark. These strings may originate in another dimension without gravity.
When Capra was writing in the 1970s, the S-matrix theory, a precursor to string theory, was on the rise (though still on the fringe).
Capra wrote: “The ‘I Ching’ is perhaps the closest analogy to S-matrix theory in Eastern thought. In both systems, the emphasis is on processes rather than objects. In S-matrix theory, these processes are the particle reactions that give rise to all the phenomena in the world of hadrons [a type of subatomic particle].
“In the ‘I Ching,’ the basic processes are called ‘the changes’ and are seen as essential for an understanding of all natural phenomena.”
3. Lao Tzu’s Understanding Related to Subatomic Particles
Lao Tzu, the founder of Taoism in the 6th century B.C., wrote: “Tao gave birth to one, one gave birth to two, two gave birth to three, three gave birth to all the myriad things. All the myriad things carry the yin on their backs and hold the yang in their embrace.”
Some say this comment is related to the various levels of particles: molecules, atoms, electrons, and so on.
Electrons are subatomic particles with a negative electric charge. Protons are subatomic particles with a positive electric charge. These charges could be related to the yin and yang polarities of Taoism.
The ancient Greeks also theorized about atoms. Electrons were only discovered in 1897 and the other subatomic particles followed.

Differences in Priorities
The goals of ancient Chinese science were different than those of modern physics. Ancient Chinese science concentrated on the spiritual, and it recognized the incorporeal as well as the corporeal. The comparison between ancient Chinese science and modern physics remains imprecise to a certain extent because the framework and approach is different.
Some of the greatest modern physicists have nonetheless been inspired by, and have identified with, ancient Chinese science.
Quantum physics has shown that the observer can change the outcome of an experiment simply through the act of observing. “Mystics also say the observer and observed fuse, they can no longer be separated,” said Capra in a recorded interview published on YouTube. It is possible that the intent of the researchers could even influence the outcome of the experiments. Some studies have begun to show the effects of human mind-intent on physical reality, though the subject has not yet been embraced by mainstream science. Dean Radin of the Institute of Noetic Sciences and William A. Tiller of Stanford University are two scientists, for example, who are exploring this topic.
The spiritual starting point of the ancient science and the materialist starting point of modern science may produce different results.
“Our Western science ever since the 17th century has been obsessed with the notion of control, of man dominating nature,” Capra said. “This obsession has led to disaster.”
