This is the fourth seminar of the series: "The interdisciplinary contribution of Giorgio Parisi to theoretical Physics". Starting from the paper "Asymptotic freedom in parton language", G.Altarelli, G.Parisi (1977), I review the seminal contributions by Giorgio Parisi that turned QCD from a model into the accepted theory of strong interactions. On top of the celebrated QCD evolution equations, these include resummation, renormalons, and a variety of results that span the spectrum from deep field-theoretic insights to concrete phenomenological applications. I will summarize some of the underlying insights, and the way they typically arise from a combination of technical magic and visionary insight.
