I was threatened with violence because I asked a math
question. That was
1975. Fortunately, I think we mostly got over her.
Early 1960s, in fifth grade, I was "sent to the Principal's office" for
discipline for insisting that PI was NOT exactly 22/7, inspite of the
textbook stating, "PI is about 3.1416 or 22/7", which the teacher
interpreted as meaning exactly 22/7.
Life would be simpler if it was a rational number! Then we could all
learn trig in base 7!
