The dangers of non-empirical confirmation
... [1], Richard Dawid describes some of these non-empirical arguments that motivate theoretical physicists’ confidence in a theory, taking string theory as case study. This may imply that the use of non-empirical arguments is somewhat of a novelty in scientific practice. It is not. But the theorists’s ...

Natural Nonlinear Quantum Units and Human Artificial Linear
... Nevertheless, modern “Planck scale physics“ relies on constants extrapolated from linear scales. Applying linear rules to nonlinear systems usually generates pseudo-scales and -predictions. This argument could vindicate fundamental high-energy scales that emerge by combining fundamental constants ob ...
