I think that we all experience this to one degree or another. Albert Einstein described the phenomenon as this: "The knowledge that we have can be analogous to a circle. Inside the circle is what we know and what we call knowledge; outside the circle is what we don't know and need to explore. As our circle of knowledge expands, so does the circumference of darkness surrounding it. So the more we know, the more we feel that we don't know."
