I saw this on tiktok today and I wanted to learn more about what I am seeing. I really do not understand what I am looking at? Are these atoms? are these the shape of caffeine at its molecular structure? I was caffeine under a microscope? they were super sharp pointy looking glass? Does that sound so off it makes no sense? Then I guess that shows how little I know about this. Haha. Please help point me ik the directions of books, YouTube, Khan Academy, or anywhere. I really want to study this.

Thank you!
