The discussion centers around the availability and value of purchasing additional volumes of a physics series, with the first volume already accessible at the library. Concerns are raised about the high shipping costs to the user's country and the complexity of the material, particularly for those not pursuing a physics degree, as the later volumes delve into advanced topics like quantum mechanics without sufficient mathematical background. Suggestions include exploring second-hand editions available on platforms like Amazon or AbeBooks, as well as considering cheaper Asian print editions. The conversation concludes positively, noting that the college library has ordered the remaining volumes, alleviating the need for purchase.
