Syukuro Manabe, Klaus Hasselmann, and Giorgio Parisi have been awarded the Nobel Prize in Physics for their “groundbreaking contributions to our understanding of complex physical systems” in 2021. Manabe, 90 has US citizenship. Hasselmann, 89, is German and Parisi, 73, is Italian. The contributions of Syukuro Manabe and Klaus Hasselmann to “physical modelling of Earth’s climate, measuring variability, and accurately anticipating global warming” were recognized.
Giorgio Parisi, professor at the Sapienza University of Rome, received the second part of the prize for “discovering the interaction of disorder and fluctuations in physical systems from atomic to planetary scales. Parisi’s contributions to the theory of complex systems are among the most significant.
It is common for several scientists who work in related fields to share the prize. Last year, the prize went to American Andrea Ghez, Roger Penrose of Britain and Reinhard Genzel of Germany for their research into black holes.
The prestigious prize includes a gold medal and a cash prize of 10 million Swedish kronor (about $1.14 million). The award money originates from a legacy left by Alfred Nobel, the prize’s founder, who died in 1895. The announcement was made by the Nobel Assembly on Tuesday, a day after they announced the names of winners of the coveted prize in the field of medicine. Americans David Julius and Ardem Patapoutian won the prize on Monday for the discovery of receptors in the skin that sense temperature and touch.
