Physical chemistry
Hello. And welcome to Wikipedia. I reverted your edit to the Physical chemistry article (see this link). The disciplines involved in Physical chemistry appear to be already covered in the section where you posted your entry. Also, if you notice the previous content is referenced. Before making major changes such as this, please discuss on the talk page of this article.

Sources (or references) are usually required that agree with whatever content you add. Please WP:Verification, WP:Reliable Sources, and WP:No original research for starters. Additionally, take a look at the above "Welcome" template. Hopefully this is helpful. In fact I will open a discussion on the talk page for you, in case you don't have experience with doing so. If you have any questions please feel free to contact me on my talk page. Regards, ---Steve Quinn (talk) 06:22, 26 April 2020 (UTC)
