String theory is changing the relationship between mathematics and physics. The central role is played by the phenomenon of duality, which is intrinsic to quantum physics and abundant in string theory. The relationship between mathematics and physics has a long history. Traditionally, mathematics provides the language physicists use to describe nature, while physics brings mathematics to life: ...

Abstract The concept of holography has lured philosophers of science for decades, and is becoming more and more popular in several front areas of science, e.g. in the physics of black holes. In this paper we try to understand things as if the visible universe were a reading of a lower dimensional hologram generated in hyperspace. We performed the whole process of creating and reading holograms ...

’t Hooft has recently developed a discretisation of (2+1) gravity which has a multiplevalued Hamiltonian and which therefore admits quantum time evolution only in discrete steps. In this paper, we describe several models in the continuum with single-valued equations of motion in classical physics, but with multiple-valued Hamiltonians. Their time displacements in quantum theory are therefore ob...
