[edit]I have realized after finding an article discussing stable glasses and their relation to the Johari-Goldstein beta-relaxation that I know little about the Johari-Goldstein beta-relaxation... Upon realizing this I did what any normal person would do and came to wikipedia to get some starting citations and pretty much nothing was here. Martin Goldstein is a name I know from during my PhD as the guy who essentially fathered the PEL picture in 1969. This picture of glass formation is widely used today to understand at a phenomenological level the glass transition. Some people (a younger version of myself included) often will over simplify this model while simultaneously extracting more from it than maybe they should, but one of the little details that I had missed was the idea that the presence of two relaxations in supercooled liquids was a direct consequence of his PEL formalism proposed in 1969. I have thus updated some of the wording in the first couple sentences and added citations to some relevant papers. The next several statements, from what I can gather, are true, but require better citations.
Here is a list of what I think we need to do with this article.
- The flow needs to be worked out such that it is not one long paragraph and individual paragraphs contain individual ideas.
- Citations need to be added for a broad portion of the statements
- Terms need to be linked to elsewhere on wikipedia for reference
- I need to do more reading and return to this article and update it further and check its factuality. — Preceding unsigned comment added by Mthees08 (talk • contribs) 15:50, 8 September 2020 (UTC)

[edit]I've done more reading and started to parse out ideas on the page. I will keep working on it slowly, though that middle section needs substantial work. I have covered items 1 and 2 partially from my previous list. I have done some more reading (item 4) but the web if information regarding the potential energy landscape and beta relaxations in molecular glasses is quite large. I added a small addendum that attempts to at least tie what is written (which largely cites and references small molecule glasses) to polymeric glasses. Mthees08 (talk) 18:08, 9 September 2020 (UTC)
