My fb feed yesterday was filled with wishes of happy pi day. I love pi day, I love pie and I like math. I then realized, everyone else on my feed does too. So who am I reaching when I post? Most of my friends think the same way that I do. Am I changing anyone’s mind? Not really, at least not using my social media. But I make friends pretty much every day and I’d like to think that I give them a good impression of scientists as a species.
