This was bizarre to me, as very few companies do massive amounts of materials research and which also is split fairly evenly across the spectrum of materials, in disparate domains such as biomaterials and metal alloys. I did some “deep research” to confirm this hypothesis (thank you ChatGPT and Gemini)
"I know it's not actually research, but I did it anyway."
Good grief. At least say "I thought this part was particularly interesting" or "This is the crucial bit" or something in that vein. Otherwise, you're just being odd and then blaming other people for reacting to your being odd.
