Since graduating I have mostly interacted with non-scientists.  Husband is a scientist, of course, and sometimes we go to his work parties, but by and large, nearly everyone I know here is not a scientist.  In talking to these non-scientist friends, I have discovered that not everybody has the same types of conversations that we have.  Two recent examples spring to mind:

1.  Most people, upon setting up an ultrasonic humidifier in their daughter’s room think merely in terms of making the air easier to breathe while their daughter has a cold.  Apparently, they do not have lengthy conversations about how an ultrasonic humidifier actually works, and they certainly don’t discuss the nature of temperature and what you are actually measuring when you measure temperature.

2.  Most people, when giving their daughter a bath, make words with the little foam letter bath toys that you stick to the tile and they probably put away the letters after the bath is done.  They do not keep rearranging the letters each time they use the toilet such that they have a silent argument about which is better:  PV = nRT or PV = NKT.

I’m sure there are more examples, but since I see nothing unusual about these conversations, I don’t realize that non-scientists don’t talk about these things until I tell a non-scientist friend about the conversation (they find these conversations highly amusing).
