If asked, what are some limitations of B3LYP? How does PBE rank in the Biblical analogization of DFT functionals known as 'Jacob's Ladder'? What is the difference between wave-function (WF) and DFT methods? Or even what do the acronyms stand for? Many students and nonexpert researchers would likely struggle with the answers. User-friendly commercial software with DFT implementations are largely 'black boxes', whereby a molecule, basis set, and functional are given as input and an Papers using DFT in this sense do not represent theory developments and, thereby, should not be regarded as resources for learning the underlying principles. There are, to be sure, many excellent review articles detailing the history of the field and current trends, from early developments with the 𝑋 𝛼 method to more recent work with machine learned and hybrid functionals, including a 70-author perspective released last year with lively debates between experts. Other tutorial reviews provide more actionable information in the way of functional selection and treatment of dispersion interactions, which include Head-Gordon et al's compendious benchmarking study featuring 200 functionals. Several monographs have also been published on the subject. Nonetheless, these resources have largely not translated into physical chemistry curricula at the university level, particularly for undergraduates, like related approaches in electronic structure theory have.
