Solution to the Problem:

1. Series
2. Algebra
3. Ellipse
4. Conic
5. Lateral
6. Maximun
7. Nonagon
8. Regular
9. Area, Era
10. Cubic
11. Tangent
12. Minimum
13. Einstein
14. Newton

James Alarie sent in his answer in the following form:
a math SERIES on ALGEBRA should include the ELLIPSE as a CONIC section cut on the LATERAL.   the MAXIMUM NONAGON has REGULAR AREA not related to its CUBIC TANGENT MINIMUM.   EINSTEIN and NEWTON agree.
