The Nobel Prize in Physics 2021 was awarded "for groundbreaking contributions to our understanding of complex systems" with one half jointly to Syukuro Manabe and Klaus Hasselmann for climate modelling and the other half to Giorgio Parisi "for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales." Georgio Parisi is one of the most creative and influential theoretical physicists in recent decades. His work has a large impact on different areas of physics, spanning the realm of particle physics (Altarelli-Parisi equations), growth processes (Kardar-Parisi-Zhang equation), disordered systems (replica method for spin glasses, stochastic resonance in nonlinear systems), turbulence, immune system analysis or the dynamics of flocking birds. Common to most of these systems is that they are complex, where the whole is more than the sum of its parts. As Parisi himself says: "Most of the research that I have done is to get at this thing: how complex collective behavior may arise from elements that each have a simple behavior." I will give a short overview of the diverse work of Georgio Parisi, focusing on four subjects: spin glasses, stochastic resonance, growth phenomena and flocking dynamics.
