This is not a research article, but a collection of updates, corrections, terminology normalizations, and questions/answers (Q/A) for my 39 of SunQM series articles that have been posted at the preprint server viXra.org (from April 2018 to February 2026). The suggested reading sequence for these 40 posted SunQM series papers is: SunQM-1, 1s1, 1s2, 1s3, 2, 3, 3s1, 3s2, 3s6, 3s7, 3s8, 3s3, 3s9, 3s4, 3s10, 3s11, 4, 4s1, 4s2, 5, 5s1, 5s2, 7, 6, 6s1, 6s2, 6s3, 6s4, 6s5, 6s6, 6s7, 6s8, 6s10, 6s9, 6s11, 7s1, 7s2, 8, 9s1, and 9s2. During my ~10 years (2014 ~ 2025) closed-door development on the {N,n} QM (through the "global energy minimization" kind of research), some of my early stage work lacks of consistency with the late stage work, and thus needs to be updated and corrected. Those important updates and corrections have mostly been presented in the late stage SunQM articles. The current paper includes the rest updates and corrections (that may be less important). The previous paper (SunQM-9s1: Update u2026 (part-1)) covered the updates for SunQM-1, 1s1, 1s2, 1s3, 2, 3, 3s1, 3s2, 3s6, 3s7, 3s8, 3s3, 3s9, 3s4, 3s10, 3s11, 4, 4s1, 4s2, 5, 5s1, and 5s2. The current paper (SunQM-9s2: Update u2026 (part-2)) covers the updates for SunQM-7, 6, 6s1, 6s2, 6s3, 6s4, 6s5, 6s6, 6s7, 6s8, 6s10, 6s9, 6s11, 7s1, 7s2, 8, and 9s1. Steve Wolfram once mentioned that he developed the online calculator "Wolfram Alpha" for the purpose of democratizing the math [citation at youtube video?]. After I discovered the Solar {N,n//6} QM structure and then built a single master table of {N,n//6} QM structure for our universe (see SumQM-7’s Table-1), I wish that the novel {N,n//q} QM also will democratize the QM theory. The {N,n} QM was built on three building blocks: the Newtonian mechanics (or the classical physics), the Bohr-QM (i.e., rn = r1 n^2 for the H-atom), and the Schrodinger equation/solution for the H-atom. Thus, I also wish that the {N,n} QM (or any fragment of it) can be the useful building material for other scientists (or the scientific community) to build either the more completed QM theories, or the more diversified QM theories.
