It recognizes that a student in a developing nation may not have ₹650 (or $40) for a new edition, but does have a smartphone and a spotty internet connection. The PDF becomes a great equalizer—or a great thief, depending on your ethics. But ethics, like phase equilibrium, is rarely binary.

Without the physical page, do we lose some subtle connection—the way a metallurgist runs a thumb over a fracture surface, reading it like braille? Perhaps. But perhaps the PDF also democratizes.
