Unitary Transformation & Matrix Symmetry

edit

This chat with Bard has me convinced that discussions between Bard and WMF editors could be mutually beneficial.

Key points in this chat:

  • I was working on a physics project, where it was obvious that a symmetric matrix (aij=aji) maintained that symmetry under a rotational transformation (a'=RTaR.) I assumed this would be valid for any unitary transformation and any nxn symmetric matrix. Just to be sure, I decided to do a "quick" check using Bard. It turned out to be far from quick.
  • To my surprise Bard claimed that all symmetric matrices do not remain symmetric under a unitary transformation. After a few exchanges, I discovered that Bard and I had a serious misunderstanding as to the meaning of an nxn matrix. My question and Bard's answer can be found at the following link:
#I am confused. A has nine elements. But the transformed matrix, B, has 27 elements. I though B would have nine elements.
  • Bard offered to sort things out, so I took Bard up on the offer. I soon reached a point of diminishing returns, that caused me to ask a crucial question; Bards answer can be found by clicking the following link:
#Just out of curiosity, was this conversation useful to you? If so, I will make it a habit to discuss a calculation where you made a mistake.
  • Bard reiterated its "interest" in getting help from me (and presumably other WMF editors) in its response to my closing message to Bard:
#I will post this on Wikiversity and leave a note on a Wikipedia talk page. Don't worry, this problem will get solved. Goodbye, for now. I will sign off as I would on Wikipedia/Wikiversity --user:Guy vandegrift
This quote is from Bard's closing remark:
I never told Bard what Wikipedia/Wikiversity is, so Bard already knew that it was about "open discussion and collaborative problem-solving" (as Bard put it.) I also liked it that Bard addressed my by my username. Guy vandegrift (discusscontribs) 23:23, 6 February 2024 (UTC)Reply
