Intercalation and deintercalation are processes often discussed in the context of materials science and chemistry, but their underlying principles are rooted in physics. The discussion highlights a conflict between the disciplines, as some argue that these processes should be considered within physics due to their fundamental nature. A quote from Ernest Rutherford emphasizes the primacy of physics in scientific inquiry, suggesting that chemistry may be secondary. However, the conversation also points out the need for clarity on academic guidelines regarding the inclusion of chemistry in physics coursework. Ultimately, the relationship between intercalation, deintercalation, and physics remains a nuanced topic that warrants further exploration.
