The Nobel Prize in Physics 2021
Born: 4 August 1948, Rome, Italy
Affiliation at the time of the award: Sapienza University of Rome, Rome, Italy
Prize motivation: “for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales”
Prize share: 1/2
Our world is full of complex systems characterised by randomness and disorder. Around 1980, Giorgio Parisi discovered hidden patterns in disordered complex materials. His discoveries are among the most important contributions to the theory of complex systems. They make it possible to understand and describe many different and apparently entirely random materials and phenomena, not only in physics but also in other, very different areas, such as mathematics, biology, neuroscience and machine learning.
