Learning about mathematics from Steven Wolfram is like learning about computing
from Bill Gates. You just have to remember that he developed it all
singlehanded.

Typical of the Yanks to get their units mixed up. :-)

Anyone found a reference to gradian in an English dictionary (or maths
book even) rather than an American one.

Curiously the Shorter Oxford has 'grade' as a 1/90th of a right angle as
opposed to a 1/100th and an earliest date of 1593.

My Oxford Dictionary shows the use of grade as the 1/90th having been
introduced in 1511 and the 1/100th introduced in 1801

and just to bring the whole thing back on topic, the same book defines
grade as "to lay out (the plan of a country) by degrees of latitude
and longitude" with a date of 1600
