It started with very strange experimental results, continued in a new physical theory about the behavior of photons, and in the future may improve our smartphone screens and allow faster data communication. faster data

The scientists took advantage of the fact that chirality affects an electron property called "spin", which is characterized by two states - "spin up" and "spin down" - similar to the spinning of a spinning top clockwise or counterclockwise. Illustration: Prof. Ron Naaman, Weizmann Institute
