Newton wrote in the 17th century and vectors came into fashion in the
19th century.

No.
In German we use an active term for learning ('lernen'), while 'being
educated' is a passive phrase, which has no counterpart in German,
except maybe in prisons ('belehrt werden').
The entire concept of 'education' is actually British and adopted by
institutions in the USA.
