Looks like someone was trying to learn quadratic equations by graphing conic sections.Looks like someone was trying to learn quadratic equations by graphing conic sections.It almost looks like they may have been guided by a magnetic north instead of true north. However, in “recent” times, the declination is about 10 degrees east, so the opposite of this circle. (Found some calculations all the way back to 1000 BC!)
I need to read the article, but it may have been quite different if it is 10,000 years old.
May have been the inspiration for the ST:TNG pilot, “Encounter at Farpoint”.
