Digitalized

a fundamental gap between computerized mathematics at one side and physics and
reality at the other side? Here a photograph of the inside of a computer

More and more our knowledge seemed mainly based on mathematized and digitalized processes of information. Is there a fundamental gap between computerized mathematics at one side and physics and reality at the other side? Here a photograph of the inside of a computer as the looking glass information machine we nowadays hardly can do without. In the past mathematics was used as an instrumental aid in a variety of parts of the scientific lines of work. Not only for physics, but also chemistry, biology cosmology and for such areas as meteorology, insurance calculations and financial analyses. Modelling theoretical insights and experimental possibilities were digitalized. Therefore last decades in depth knowledge of many branches of science rapidly increased. Now computers are used everywhere and convert theoretical concepts into algorithms of 1 and 0 sequences. Pictures are pixelated so to speak. Time after time to our own surprise mathematics and physics seemed to be far more deeply involved in each other than we thought being possible. Math appeared to be not only an instrumental aid, not only intertwined with physics, but pervading physics almost completely. Space and time once were mathematical constructions helping us calculating place and velocity of an object. According to the theory of relativity space, time, velocity, mass all has to do with reference frames of an object and the observer. And more so space- time has become a reality and assessed to be an object by itself. Unlike space, time is described as an imaginary property. And then there is quantum mechanics. For a quantum system a phase- space or momentum-space or whatever space can be constructed with as many axis’s as seems to be convenient. As many degrees of freedom, dimensions and imaginary axis’s as we like to use, make handling properties far more possible. The degree of abstraction we are able to construct increased. Contradictories appeared. The theory of relativity being a local theory somehow did not merge with quantum mechanics being non- local in essence. But probably string theory could combine both fundamental theories. Strings about the Planck Length 10 ^ -35 m could dependable on their frequencies be interpret as particles. Ten or eleven dimensions could deliver the wished for results. Also a parallel universe can come in handy. That way a unification theory for quantum gravity may be constructed. Someday much stronger acceleration machines can perhaps support the string theory with experimental results. Recently Itzhak Bars and his Ph.D student Dmitry Rychkov from the University of Southern California could construct a link between string field theory and quantum mechanics. They used the geometry of the joining and splitting of strings to explain commutation rules of quantum mechanics. ( Physics Letters B, 2014 ) It is interesting that Bars and Rychkov have showed here that string theory is not contradictory to some rules of quantum theory. Question remains about how powerful string theory could be to predict new phenomena. Maybe following this method next steps could lead the way for string theory to describe quantum gravity and some beginning of constructing a unification theory becomes more possible. In general the question remains what the more and more digitalized processed descriptions of phenomena of the last decades has to do with reality, with truth about the universe around us? Or could It be half true and half a digitally reduced fantasy.
Only if possible an answer may follow.
