@rbellinger My favorite Friday activity is to go to #PupinHall at #ColubmiaUniversity for the #AstronomyOutreach program. Its amazing and its free. Went to a very basic presentation at #LowellObservatory in #Flagstaff and it wasn't free and was too basic. They are n't here yet and don't have a calendar yet. I searched on #Pupin and found this thing about a coil. Might be the same Pupin. They are both Michaels.
