      The solving of a koan demands a supreme effort of concentration and involvement from the student. In books about Zen we read that the koan grips the student’s heart and mind and creates a true mental impasse, a state of sustained tension in which the whole world becomes an enormous mass of doubt and questioning. The founders of quantum theory experienced exactly the same situation, described here most vividly by Heisenberg:

      I remember discussions with Bohr which went through many hours till very late at night and ended almost in despair; and when at the end of the discussion I went alone for a walk in the neighbouring park I repeated to myself again and again the question: Can nature possibly be so absurd as it seemed to us in these atomic experiments?6

      Whenever the essential nature of things is analysed by the intellect, it must seem absurd or paradoxical. This has always been recognized by the mystics, but has become a problem in science only very recently. For centuries, scientists were searching for the ‘fundamental laws of nature’ underlying the great variety of natural phenomena. These phenomena belonged to the scientists’ macroscopic environment and thus to the realm of their sensory experience. Since the images and intellectual concepts of their language were abstracted from this very experience, they were sufficient and adequate to describe the natural phenomena.

      Questions about the essential nature of things were answered in classical physics by the Newtonian mechanistic model of the universe which, much in the same way as the Democritean model in ancient Greece, reduced all phenomena to the motions and interactions of hard indestructible atoms. The properties of these atoms were abstracted from the macroscopic notion of billiard balls, and thus from sensory experience. Whether this notion could actually be applied to the world of atoms was not questioned. Indeed, it could not be investigated experimentally.

      In the twentieth century, however, physicists were able to tackle the question about the ultimate nature of matter experimentally. With the help of a most sophisticated technology they were able to probe deeper and deeper into nature, uncovering one layer of matter after the other in search for its ultimate ‘building blocks’. Thus the existence of atoms was verified, then their constituents were discovered—the nuclei and electrons—and finally the components of the nucleus—the protons and neutrons—and many other subatomic particles.

      The delicate and complicated instruments of modern experimental physics penetrate deep into the submicroscopic world, into realms of nature far removed from our macroscopic environment, and make this world accessible to our senses. However, they can do so only through a chain of processes ending, for example, in the audible click of a Geiger counter, or in a dark spot on a photographic plate. What we see, or hear, are never the investigated phenomena themselves but always their consequences. The atomic and subatomic world itself lies beyond our sensory perception.

      It is, then, with the help of modern instrumentation that we are able to ‘observe’ the properties of atoms and their constituents in an indirect way, and thus to ‘experience’ the subatomic world to some extent. This experience, however, is not an ordinary one, comparable to that of our daily environment. The knowledge about matter at this level is no longer derived from direct sensory experience, and therefore our ordinary language, which takes its images from the world of the senses, is no longer adequate to describe the observed phenomena. As we penetrate deeper and deeper into nature, we have to abandon more and more of the images and concepts of ordinary language.

      On this journey to the world of the infinitely small, the most important step, from a philosophical point of view, was the first one: the step into the world of atoms. Probing inside the atom and investigating its structure, science transcended the limits of our sensory imagination. From this point on, it could no longer rely with absolute certainty on logic and common sense. Atomic physics provided the scientists with the first glimpses of the essential nature of things. Like the mystics, physicists were now dealing with a nonsensory experience of reality and, like the mystics, they had to face the paradoxical aspects of this experience. From then on therefore, the models and images of modern physics became akin to those of Eastern philosophy.

       Chapter 4 The New Physics

      According to the Eastern mystics, the direct mystical experience of reality is a momentous event which shakes the very foundations of one’s world view. D. T. Suzuki has called it ‘the most startling event that could ever happen in the realm of human consciousness … upsetting every form of standardised experience’,1 and he has illustrated the shocking character of this experience with the words of a Zen master who described it as ‘the bottom of a pail breaking through’.

      Physicists, at the beginning of this century, felt much the same way when the foundations of their world view were shaken by the new experience of the atomic reality, and they described this experience in terms which were often very similar to those used by Suzuki’s Zen master. Thus Heisenberg wrote:

      The violent reaction on the recent development of modern physics can only be understood when one realises that here the foundations of physics have started moving; and that this motion has caused the feeling that the ground would be cut from science.2

      Einstein experienced the same shock when he first came in contact with the new reality of atomic physics. He wrote in his autobiography:

      All my attempts to adapt the theoretical foundation of physics to this (new type of) knowledge failed completely. It was as if the ground had been pulled out from under one, with no firm foundation to be seen anywhere, upon which one could have built.3

      The discoveries of modern physics necessitated profound changes of concepts like space, time, matter, object, cause and effect, etc., and since these concepts are so basic to our way of experiencing the world it is not surprising that the physicists who were forced to change them felt something of a shock. Out of these changes emerged a new and radically different world view, still in the process of formation by current scientific research.

      It seems, then, that Eastern mystics and Western physicists went through similar revolutionary experiences which led them to completely new ways of seeing the world. In the following two passages, the European physicist Niels Bohr and the Indian mystic Sri Aurobindo both express the depth and the radical character of this experience.

      The great extension of our experience in recent years has brought to light the insufficiency of our simple mechanical conceptions and, as a consequence, has shaken the foundation on which the customary interpretation of observation was based.4

       Niels Bohr

      All things in fact begin to change their nature and appearance; one’s whole experience of the world is radically different … There is a new vast and deep way of experiencing seeing knowing contacting things.5

       Sri Aurobindo

      CLASSICAL PHYSICS

      The world view which was changed by the discoveries of modern physics had been based on Newton’s mechanical model of the universe. This model constituted the solid framework of classical physics. It was indeed a most formidable foundation supporting, like a
