Although robust 1d physics has been seen in truly 1d fabricated structures such as nanotubes and quantum wires, general theoretical arguments predict that below a crossover temperature electron hopping between the many chains of a solid inevitably restores some familiar 3d state. I will present strong evidence from quantum critical scaling in angle resolved photoemission spectroscopy lineshapes that the normal state of anisotropic superconducting metal Li0.9Mo6O17 evades these theoretical arguments to manifest a three dimensional metallic phase that is nonetheless rooted in 1d physics.
