I have always found that people that enjoy science are comfortable with uncertainty. I worked at Bell Labs for 16 years from the mid 1980s through 2000, and I found a lot of people still looking at things that "we all understand" and still wondering about how it really worked.
Science is never 'settled'. There is the current understanding of the art, but that current understanding is not always fulfilling. There are edges and holes in most domains in science where people are poking around wondering how it really works.
A lot of the things I implemented as an engineer (I am not a scientist, but I worked with scientists) were attempts to answer questions. Many of them having to do with "how do we measure this thing, without touching it?" Modeling information and making decisions based on observations against what you were expecting to observe.
