They can—but that doesn't mean we should assume it's a silly mistake (as opposed to a deep one) without more information than that he's an accomplished researcher.
To add to this, I have a Ph.D. in applied mathematics. I am also an accomplished researcher, albeit retired.
I make more mistakes by 09:00 than most people will make all day. Hell, my girlfriend would suggest that we can move that time forward a couple of hours.
