Yesterday I found out that the project I worked on as a postdoc won a major honor. It wasn't until someone emailed me a congratulatory note that I realized that my name had been included in the nomination as well!
I spent about an hour laughing about the unexpected honor. A friend at work told me that I should be proud and I deserved the recognition.
I don't feel like I do, but that is mostly because I have not worked on that project for several years. But when I think about it, I actually did make a substantial contribution: although they don't use the algorithms I developed, they do still use the framework I developed for them.
