As we shall see, this notion is quite silly, although people—who are either not physicists, mathematicians, or computer engineers, or just happen to have an academic title without an understanding of these subjects—tend to profess it over and over. This post explores…

    Information, Uncertainty and Choice

    In the previous post, I described how modern science employs two contradictory ideas—possibility and choice—although in practice only one of them can be used, resulting in incompleteness. An example of that incompleteness is that quantum theory describes the world as a possibility which needs to be completed by a choice, although that choice cannot be reduced to that possibility. The predictions of the theory therefore are probabilistic, and we cannot…

Science until that point had worked explicitly to keep mind and consciousness out of the study of the material world, and were it not for the considerable reputation that John…
