Inserting a 4 foot stick half way into a big tank of water at a 45 degree
angle, the refraction can be measured or closely approximated.
How were the refraction adjustments initially calculated for the
atmosphere?
What was the methodology used? I don't think it was as easy as the stick in
the water method?
Thank you.
