understanding is a multi dimensional space =AO the language is a projection in that space. or =n arrow in category theory. the local point has hi=tory . so like the play appears different from every sea= in the theatre the integaration over each point=C2 projects his understanding on the language.

Gary Marcus was there, too, but ann=yed everyone by being too insecure to deal with his incompetence.

We just moved into a new apartment; the previous one had only two bedr=oms and this one has three, so I can have a study. It seems that we are as=lucky with the new landlords as with the previous ones.
Bests, and thank you for everything!
