I used it because we both studied physics (or rather, I studied engineering, so applied physics), so it was experience we could both relate to.

Edit: On the note of the frustration of having to Google words constantly, yeah that would be frustrating and make technical literature much harder to read. Maybe an imperfect solution could be to install an extension that provides the definition of a word in a pop up if you highlight a word. I used to have an extension that did that, maybe it could be of use. Don’t remember what it was called though
