On October 5 the Nobel Prize Assembly at the Karolinska Institutet in Stockholm awarded the Nobel Prize in Physics 2021 to Italian theoretical physicist Giorgio Parisi. Professor Parisi was awarded the Nobel Prize for his research on complex systems. Italy thus celebrates another important recognition.

Born in Rome in 1948 and graduated in physics at Sapienza University of Rome, Parisi worked as a researcher at the INFN National Laboratories of Frascati and was vice president of the Accademia dei Lincei. He authored four books and over six hundred scientific articles on particle physics, fluid dynamics, statistical mechanics and neutral networks. 

Giorgio Parisi is the sixth Italian physicist to receive the Nobel Prize. The other laureates are Guglielmo Marconi (1909), Enrico Fermi (1938), Emilio Segré (1959), Carlo Rubbia (1984) and Riccardo Giacconi (2002). “I’m happy, I didn’t expect it. But I knew there might be some possibilities” said Professor Parisi during a phone call with the Royal Swedish Academy of Sciences.

Syukuro Manabe and Klaus Hasselmann, who share half of the prize, were jointly honored “for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming”, while Giorgio Parisi, who claimed the other half of the prize, was awarded “for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales”. 

Research is extremely important to create the future. It is important that research in Italy receives proper funding“, commented Professor Parisi. “This is a good time to invest in research because this means investing in young people he added. “It’s clear that for the future generations, we have to act now, in a very fast way” against climate change.

President of the Italian Republic Sergio Mattarella expressed great satisfaction with the awarding of the Nobel Prize in Physics to Professor Parisi and congratulated him on a “very important recognition that honors Italy and its scientific community“.

Felicitations also came from Prime Minister Mario Draghi, who congratulated Professor Parisi on behalf of the whole Council of Ministers. Draghi also announced that he will soon receive Professor Parisi at Palazzo Chigi to celebrate his extraordinary success. 

This is a historic day for Italy. I want to say a big thank you to Giorgio Parisi, on behalf of many people” commented the minister of University and Research, Maria Cristina Messa
