4. The Spirit and Quantum MechanicsGrasping the concept of quantum mechanics requires great imagination. Matter behaving both as particles and waves is far removed from the way in which the material world usually is perceived. On an elementary level it is difficult to describe the diffuse material world, because place and impulse cannot be measured precisely simultaneously. The uncertainty principle causes a measuring problem that has far-reaching consequences. It is a wondrous thing when the phenomenon one is trying to measure collapses. It happens because of some sort of interaction between matter and observation, which presupposes a subjective power that influences matter at an elementary level. Measuring adds quanta of light to the object that is being observed. The spirit could be a candidate to explain this phenomenon. The observer causes a measuring problem at quantum level and the observer causes relativity at macro level. The spirit (cocoon) is present in all systems of life and matter, despite the success of reduction ism. Time manifests itself as a wave at quantum level. The measuring problem within quantum mechanics was one of the main reasons that led me to develop my theory. The observer (spirit) is part of the system. The object of observation is influenced by measuring equipment that is set and operated by human power. Interpreting measured data is a spiritual process. When and where something is measured , is determined by humans, while the actual measuring is done by machines that are products made by humans. Thus human and spiritual acts and judgments are indirectly represented through the measuring equipment.
