Here is an email I recently received from a fellow physics teacher: "First, let me start by saying that I greatly appreciate your videos and routinely assign them to my physics students.  You are doing great things for physics education, please keep it up.

Second, I must say that you are driving me crazy.  When you introduce or write out the names of units that are named for a person, you keep capitalizing them when they do not want to be capitalized.  For example, joules are joules, not Joules.  They are abbreviated J, but when written out they are joules (otherwise, when written out capitalized, you are talking about a scientist’s family members).  Same for watts (W), newtons (N), pascals, you get the idea.  Now you are probably feeling incredulous and wondering why this crazy physics teacher is telling you this crazy rule about units, so here is a link from another crazy source that happens to agree.  Please consider writing out person-named units with lowercase letters in your future videos.  And thanks again for your fantastic work." - Alexandra, Kuchar, Wayland High School, MA

My reply, "Thank you so much for taking the time to let me know about this, really. I don't pretend to know everything about physics (or is it Physics?) and love to learn more as I make the videos. I think it's wonderful to be corrected by a fellow physics teacher and important to highlight that we can all learn from one another." - Jon
