Many open-access PDFs available online are lecture notes from Doi's courses at various international universities. These PDFs are highly sought after because they offer simplified diagrams, practical examples, and homework problems regarding everyday phenomena (like the "coffee ring effect" or the tackiness of pressure-sensitive adhesives).
