Where blog is taken in a wide sense, including e.g. Medium, WordPress, Facebook, Twitter, etc., etc.

The main shortcoming of blogs is the lack of topic convergence across blogs. Each blog is a moderated castle. So who is the best user for a given topic, or the best content for a given tag, across the entire website?

The only reasonable free material we have for advanced subjects nowadays are university lecture notes.

While some of those are awesome, when writing a large content, no one can keep quality high across all sections, there will always be knowledge that you don't have which is enlightening. And Googlers are more often than not interested only in specific sections of your content.

Our website aims to make smaller subjects vertically curated across horizontal single author tutorials.

Basically a social network where you don't know the other people very well.

If Ciro Santilli were to write a book about quantum mechanics as of 2020 (before OurBigBook.com went live), he would upload an OurBigBook Markup website to GitHub Pages.

But there is one major problem with that: the entry barrier for new contributors is very large.

If they submit a pull request, Ciro has to review it, otherwise, no one will ever see it.

Our amazing website would allow the reader to add his own example of, say, The uncertainty principle, whenever they wants, under the appropriate section.

Then, people who want to learn more about it, would click on the "defined tag" by the article, and our amazing analytics would point them to the best such articles.

It would be really cool to have a PageRank-link algorithm that answers the key questions:However, Ciro has decided to leave this for phase two action plan, because it is impossible to tune such an algorithm if you have no users or test data.

Perhaps it is also worth looking into ExpertRank, they appear to do some kind of "expert in this area", but with clustering (unlike us, where the clustering would be more explicit).

Other dump of things worth looking into:

This paper appears to calculate the Schrödinger equation solution for the hydrogen atom.

TODO is this the original paper on the Schrödinger equation?

Published on Annalen der Physik in 1926.

Open access in German at: onlinelibrary.wiley.com/doi/10.1002/andp.19263840404 which gives volume 384, Issue 4, Pages 361-376. Kudos to Wiley for that. E.g. Nature did not have similar policies as of 2023.

This paper may have fallen into the public domain in the US in 2022! On the Internet Archive we can see scans of the journal that contains it at: ia903403.us.archive.org/29/items/sim_annalen-der-physik_1926_79_contents/sim_annalen-der-physik_1926_79_contents.pdf. Ciro Santilli extracted just the paper to: commons.wikimedia.org/w/index.php?title=File%3AQuantisierung_als_Eigenwertproblem.pdf. It is not as well processed as the Wiley one, but it is of 100% guaranteed clean public domain provenance! TODO: hmmm, it may be public domain in the USA but not Germany, where 70 years after author deaths rules, and Schrodinger died in 1961, so it may be up to 2031 in that country... messy stuff. There's also the question of wether copyright is was tranferred to AdP at publication or not.

An early English translation present at Collected Papers On Wave Mechanics by Deans (1928).

Contains formulas such as the Schrödinger equation solution for the hydrogen atom (1''):where:
