This lecture by the instructor covers the evolution of biomolecular simulations and experiments over the years, emphasizing the need for accurate models and increased sampling. It delves into force field calculations, binding sites, and the Bayesian approach to integrating data from cryo-EM, SAXS, and SANS. The presentation highlights the importance of understanding sampling and accuracy, the potential of FLOPS in simulations, and the transformative role of simulations in predicting and explaining experimental outcomes.
