Page 29, the "local lingo" section states "Cathode ray tubes are used in monitors 
and television screens and move a BEAM OF LIGHT across the back of the screen 
to produce the image on the screen." 

Should read "... and moves an electron beam (electromagnetically) across the back 
of the screen to produce the image on the screen."
