I really enjoy my work. Part of what I do puts me in situations where I learn new things and more about topics I thought I already understood. It is the second part of that sentence that tends to humble me fairly often.
When I talk to kids about space, I often tell them we know about this much about space, as I hold my fingers close together, and that there is this much to know, as I spread my arms out as far as I can.
As I walked out of a recent meeting, I began to think about how it is easy to become impressed with what we think we know when the simple fact is that there is so very much more to understand. We are separated from our students’ level of understanding by a very thin margin.
