Informationism is the Philosophy of science, based on Information Theory. Information Theory, is short, makes the relationships between matter and information. Action, which is just change the energy over time, is quantizied and has minimal value. Value of Planck Constant h (6.62e-34 [Js]). This value is just one bit of information. Information is a action and action is the source of matter. In such a way matter can be converted to information and opposite. Information is dynamic force. Matter static. Information, becuase is a action, is looking for smallet time to process the event. Matter each time collapse in minimum energy. This is becuase information and matter is existing and is limited, so the principles which rule the behaviour are trying not to overuse limited substance, which is time and energy respectively to information (action) and matter. Informationism is gathering the strong site of science with answering to most prominent questions in philosophy. Informationism is the philosophy of Information Society in twenty first century.
