It wasn’t merely about content. The best PDFs were alive: hyperlinks threaded to raw data sets, illustrative simulations that let you tug an electron and watch the molecule respond, and appendices where assumptions were peeled back and reexamined. Philip insisted on clarity without compromise—no obfuscating jargon, only precise prose that let the chemistry whisper its truths.
