According to Locher (1, p.10) Escher's father had an equation
relating the men's ages (m) and those of their ideal woman partner
(w). It was:
w = 1/2 m + 10
or, in words, the woman's age is half the man's age plus 10.
(No MCP comments, please, this was in 1878!)
Later on the same page, he refers to Escher's second wife, who was 38
when they married (Escher was 55). Locher writes "The great
difference in their ages - seventeen years - did not satisfy the
formula (given above) ..."
Now, my calculations show that m=55 and w=37 are as good a fit to the
formula as any 55-year old person can expect! So what is Locher
trying to say? (or is it just that he has misused the formula? - or
