Mathematicians Prove 2D Version of Quantum Gravity Really Works

Alexander Polyakov, a theoretical physicist now at Princeton University, caught a glimpse of the future of quantum theory in 1981. A range of mysteries, from the wiggling of strings to the binding of quarks into protons, demanded a new mathematical tool whose silhouette he could just make out. “There are methods and formulae in science which serve as master keys to many apparently different…
