: I would greatly appreciate any information you can find on the derivation of the phrase, "zero in".
ZERO IN - From "v. 1913, to adjust (an instrument or device) to zero point, take aim on a target; now especially in the phrase 'zero in on' , from earlier 'zero in,' 1944); from the noun." From "Barnhart Concise Dictionary of Etymology" by Robert K. Barnhart (HarperCollins Publishers, New York, 1995).
