It is impossible to observe reality or a physical entity without changing it due to the fact that just by watching it one can alter the outcomes and also by changing its environment or setting the outcomes can be what one has desired. Quantum theory can be understood by demonstrating this example: there is no way to calculate where a single photon in a double slit experiment will strike the photographic plate, however, we can calculate the probability that it will strike it at a certain place. Basically, the outcomes of the variables involved can be only predicted but they are not absolute; it is also known as the uncertainty principle. .
According to Capra, another important aspect of Quantum theory is the fact that matter is always in motion. Motion can be described as movement of bodies away from each other or their movement towards one another, varying in direction, velocity and momentum. For example, if one observes a dead stone, to the human eye it appears to be still with no movement, but if the stone is magnified one can see that it is full of activity. .
Quantum physics has many important explanations and one of them is the Copenhagen interpretation developed by Bohr and Heisenberg in the late 1920's. Bohr and Heisenberg believe that there is a interconnectedness in the universe and in nature. For example, during an experiment there is the observed system (the object) and the observing system (the human). First, the particle is isolated during the preparation process and during this stage the observed system must be free from external disturbances caused by the process of observation, during its preparation and measurement. During this process, particle A travels to particle B and a collision takes place, thus an interconnection is evident. It can be noted that the processes of the particle cannot be defined independently of these processes. With this idea of interconnection comes the many parallels of Quantum physics with Eastern mysticism that will be discussed in the following paragraphs.
