How can the physical world be an abstract mathematical structure?

This is Tegmark's short formulation of the "mathematical universe" (paraphrased by detractors as "reality made of math"), and he goes out of his way to stress that he means the "is" literally:"Whereas ...

What are the philosophical consequences of the undecidability of the spectral gap in quantum theory?

An article published in Nature yesterday proves that finding the spectral gap of a material based on a complete quantum level description of the material is undecidable (in the Turing sense). One of ...
