The name “Bear” is Homeric, and apparently native to Greece, while the “Wain” tradition is Mesopotamian. Book XVIII of Homer’s Iliad mentions it as “the Bear, which men also call the Wain”.[10] In Latin, these seven stars were known as the “Seven Oxen” (septentriones, from septem triōnēs).[11]Classical Greek mythography identified the “Bear” as the nymph Callisto, changed into a she-bear
by Hera, the jealous wife of Zeus.

We know what the right answer is
We don’t know what the right answer is – but we can recognize a good answer if we find it
We have a way to measure how good our current best answer is, and a method to improve it
