So then you are also OK with (which expresses the philosophy underlying the book) *The End of Theoretical Physics As We Know It* by Sabine Hossenfelder https://www.quantamagazine.org/the-end-of-theoretical-physics-as-we-know-it-20180827/ *Beyond Math* by Sophia Magnusdottir (actuailly Sabine Hossenfelder) https://fqxi.org/data/essay-contest-files/Magnusdottir_fqxi15.pdf @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
