My invitation to FTB caught me at a busy time. Last week, I was at the APS March Meeting, which is the largest physics conference in the world of the year. There were about 10,000 attendees, and about 50 simultaneous sessions throughout the week, with no lunch breaks.
Of course, I manage to find break time anyway. Quite frequently, it seems that there is not one single session going on that would be of interest to me. I just wouldn’t understand them.
In previous years, I used to find this very depressing. On my conference app, I’d bookmark all the sessions on superconductivity, which is my area of study. Then I’d sit in on a session, and find that I understood not a single talk, not even a little. And every 12 minutes there would be another talk, and another, and another, for hours. Then I’d try going to a different room focused on superconductivity, and the same thing would happen again.
It’s no wonder that impostor syndrome is so common among physicists.
