looked on internet for information about the chonchoid curve, but am unable to figure out why Nicomedes named this curve after the shell
Okay-- what is a chonchoid curver? is it the curve that is a ratio related to "golden rectangles"?-- (i think the company Sybase uses it in there logo-- )

Its on of those math things, that i never really studied, but have come across--and the resulting spiral -- is one of those curious things that is also found in nature-- { like the sequence of numbers named after....(it is on the tip of my tongue.. Fab..?? Fib..??) 0, 1,1,2,3,5,8,13...} the curve is found in seashells, such as conch shells, and other natural forms.

Or is it something else entireley?
