Syadvad, another corollary of Anekantvad, is also a cornerstone of Jainism. It has been translated as "perhaps", or "May be". That appears to me as a qualitative (or crude) definition. Can we extend and quantify it to include the uncertainty principle or derive the uncertainty principles from the framework of Syadvad? Uncertainty principle is one of the most fundamental principles applicable equally well to the realms of all physical microworld and may be (in my opinion), the cause of biologi cal evolution. The uncertainty, e.g. in energy levels give a choice for a variance in com bination or in taking part in different chemical reactions. Without uncertainty biology will be like ordinary organic chemistry such as polymerization and animate could not have evolved from inanimate. Syadvad therefore must be thought of as going beyond "may be", or used as an instrument for tolerance in society but should be seen to lead to indeterminacy and to the principle of uncertainty (?p?x-h; ?E?t=h). In manyfoldedness, or anekantvad, the uncertainty can be defined in a more profound way and for other parameters. This is the Syadvad in physical terms.
According to the principle of Saptabhangi reality can be described in seven ways i.e. it exists, it does not exist, it exists and yet it does not exist, indeterminable, its existence is indeterminable, its non existence is indeterminable and its existence as well as non existence is indeterminable or inexpressible. Saptabhangi has been explained very succinctly by Kothari in a quantum mechanical way by taking the example of a particle in a box which is divided by a partition with a hole into two compartments. Because of the particle-wave duality, the particle can be in compartment A, or in compartment B, In A and still not in A, In B and still not in B, not in A and B, in A as well as in B and in an indeterminate state (avyakta). The same solutions emerge from the considerations of quantum mechanics as has been shown mathematically by taking wave functions.
Sometimes light or a photon behaves like a compact object i.e. a particle and some times like a wave such as a ripple we see in a pond. A photon or an electron, for example, "knows" when it should behave like a particle and when it should behave like a wave. In the famous two slit experiment, a beam of photon shines through two slits and hits upon a photographic plate behind the slits. The experiment can be run in two ways: one with photon detectors right beside each slit so that the photons can be observed as they pass through the slits and or with detectors removed so that the photons can travel unobserved. When the detectors are in use, every photon is observed to pass through one slit or the other. Essentially the photons behave like particles. However, when the photon detectors are removed, a pattern of alternating light and dark spots, produced by interference of light are observed indicating that the photons behave like waves, with individual photon spreading out and surging against both the
