The discussion centers around finding resources for learning quantum physics. Participants suggest searching for books by adding "pdf" to the title in Google to locate free resources. A specific recommendation is made for a quantum physics and cosmology book, noted for being accessible though not deeply detailed. However, there is a reminder about the importance of copyright, emphasizing that sharing copyrighted materials is not permitted. A link to a set of quantum physics notes is provided as a legitimate resource, and users are directed to a Free Physics Books thread for additional options.
