• diffhist Matrix (mathematics) 20:43 +116 Jacobolus talk contribs (→Matrix multiplication: add a sentence about linear transformations; this is the fundamental feature of matrix multiplication which explains its structure)
• diffhist Matrix (mathematics) 19:54 +1 David Eppstein talk contribs (move sentence about square matrices forming a noncommutative ring from lead to square matrix section; too technical for lead and does not summarize later content)
• diffhist Group (mathematics) 17:04 +1 JayBeeEll talk contribs (null edit to add summary for previous revert (which was marked minor due to a mis-click): reverting disimprovement of grammar, that does not increase clarity)

• diffhist Matrix (mathematics) 03:20 −12 Jacobolus talk contribs (okay, we can use bold as recommended as an alternative by the MOS, instead of a definition list. having these as headings at all is a big distraction, both for the TOC and for the content itself, especially if we add hatnotes for the wikilinks)
• diffhist Matrix (mathematics) 02:03 +27 David Eppstein talk contribs (Undid revision 1292993056 by Jacobolus (talk) this is an accessibility issue; see MOS:FAKEHEADING. The wikilinks in the headings need to go, though.) Tag: Undo
• diffhist Matrix (mathematics) 01:20 −27 Jacobolus talk contribs (Undid revision 1292989484 by Gramix13 (talk) – turning these into headings seems unhelpful. they clutter the contents list and take up a distracting amount of content space for no particular benefit) Tags: Undo Reverted
• diffhist Matrix (mathematics) 00:45 +27 Gramix13 talk contribs (→Addition, scalar multiplication, subtraction and transposition: Gave the operations proper headings.) Tag: Reverted
• diffhist Matrix (mathematics) 00:43 +86 Gramix13 talk contribs (→Addition, scalar multiplication, subtraction and transposition: Added image of matrix addition.)

• diffhist Crystallography 13:53 −2,534 Ldm1954 talk contribs (Restored revision 1292264902 by OAbot (talk): This is a general page on crystallography, and the Bio section is supposed to be only general. While it is fine to add links such as to Barbara Low, it is not appropriate to add statements about CryoEM and other specialized techniques here. Please propose major changes such as these on the talk page first to obtain concensus.) Tags: Twinkle Undo

• diffhist Crystallography 23:17 +531 Biochemlife talk contribs (→Biology: Added information about cryo-EM being predicted to surpass x-ray crystallography as primary method of solving macromolecular structures. Added a couple of the now more popular 3D molecular visualization programs. Removed sentence about crystallography being used to determine the double helical structure of DNA, as that was instead determined from fiber diffraction data) Tags: Reverted nowiki added Visual edit
