Maxima by Example: Ch. 7, 8, 9, 10, and 11

As I've said before, I am not competent to judge the content of Evans' work.

However, I do recognize the (linguistic) warning signs of an INTERNATIONAL
CONSPIRACY BY OCCULT FORCES TO SUPPRESS THE TRUTH.  Evans HAS BEEN NOMINATED
for knighthood (and a Nobel!), but it has been denied to him. Formal
complaints HAVE BEEN RAISED with authorities. Einstein and Cartan ARE NAMED
as coauthors. Criminal charges are POSSIBLY PENDING. Evans is the NEW
VELIKOVSKY (not the NEW GALILEO?!).
