Handling complexity: The Hindu Editorial on 2021 Nobel Prize in Physics

Bringing to a close speculation about the winner of the Physics Nobel prize this year, the Nobel committee decided to award a trio of researchers. One half went to Syukuro Manabe of Princeton University, U.S., and Klaus Hasselmann of the Max Planck Institute for Meteorology, Hamburg, Germany, for their work in climate science. In the long line of researchers who estimated the warming of the atmosphere due to gases in it, Syukuro Manabe’s modelling, in collaboration with others — and over decades — is a classic work that showed, even in the 1960s, that the atmosphere would undergo another 2.3° C warming with the doubling of carbon dioxide content. The other half of the prize, to Giorgio Parisi from the Sapienza University of Rome, Italy, is for developing a method to sensibly study complex condensed matter systems called “spin glasses” — an outstanding feat in both mathematical and physical innovation. What ties together the seemingly disparate works — the climate science work by Syukuro and Hasselmann on the one hand and theoretical condensed matter physics work by Parisi on the other — is that both describe complex physical systems.
