The assistance of Ty Harness in my attempt to make sense of the methodology of the ancient geometers is gratefully acknowledged. Any mistakes or erroneous conclusions found on this page, however, are totally my own doing.

from the 1830's "Penny Cyclopaedia of the Society for the Diffusion of
Useful Knowledge" contends that
"Modern writers employ fractions instead of ratios, and with great advantage. But the student who leaves untouched that consideration of ratio which includes incommensurables as well as commensurables will never be more than a mathematician to a certain number of decimal places."
Then in a 2012 conference paper I found this comment about a theorem the author was preparing to discuss.
"...(I first found [it] in a newspaper, sent in by a GEOM (Geometrically Excited Old Man). For some reason, some elderly men continue to be intrigued by geometry, usually in a negative manner, trying to prove every angle can be trisected, etc.)..."
As an octogenarian I feel obligated to disclose that I may be only a two bit mathematician but I am at least half a GEOMeter.
