This contribution to the volume "From My Vast Repertoire -The Legacy of Guido Altarelli " discusses the state of our knowledge of the strong coupling. * On leave from CNRS, UMR 7589, LPTHE, F-75005, Paris, France. 1 This is based on the CT14nnlo PDF set [9], for a centre-of-mass energy of √ s = 13 TeV, taking into account the correlation of the PDFs with αs. Cross sections were evaluated with the ggHiggs code [10] (at N3LO [11]) and the top++ code [12] (at NNLO). In the case of tt production
