Corrected entry: In the opening scene, the blackboard has area = PI squared R. Area of a circle is PI R squared.
Corrected entry: The head of the Virginia City Merchants' Association is officiating at a "Beautiful Baby" contest. At three different times, he tells the four-piece band behind him to "play some music." Each time, without any discussion of which song to play and without anyone counting "one-two-three," the four musicians immediately begin playing a tune, a different one each time.
Correction: Bands practice quite a bit and know what songs they'll play and in what order, here they simply waited for their cue to play. My mom plays in a trio and during their performances, no one has to say "1-2-3", they just start playing (one person is assigned to start the piece and the others follow because they know when the first note will be played).
Correction: While the superscript 2 is close to the PI symbol, it's merely because of the writing size. The r is closer and meant to be r squared (if we had seen her write or say PI squared, that would be a mistake).
