Physics and Fiction [chapter]

Giovanni Vignale
2021 Physics and Literature  
The mythical character of a theory does not diminish its scientific validity; quite the contrary. Convincing myths are not easily found and better observations demand better myths.  ...  It is not within its power to explain reality, but it can fictionalize it and thus make it understandable, sometimes even predictable.  ...  Indeed, the level of theoretical knowledge and computational power required to achieve such a goal is stupendous: anyone who had such a power would probably find the whole framework of density functional  ...
