I already wrote a blurb at

*about Matt Parker's fantastic book, "*

**MathTango****Things To Make and Do In the Fourth Dimension**," but now that I've finished reading it, just want to add a few quick notes:

*First, I'll reiterate it's a wonderful volume -- I enjoyed the second half (which touched on several of my favorite topics, and also told perhaps the most fun story of Tartaglia's rivalry with Fior over algebraic/cubic equations) even more than the first half.*

**1)***Do note however, that at least parts of the volume may require slightly more math sophistication, or interest, or just persistence, than some of the other volumes I included on my Holiday gift list;*

**2)***i.e.*while Matt's book is a fun and educational read, not every chapter is an

*easy*read.

*Also, one small complaint: the book lacks an index, which because of the sheer number and diversity of topics/information included, would've been helpful.*

**3)***Finally, (and the*

**4)**__REAL__reason for this additional posting),

__BE__

__SURE__to read the "

__Acknowledgements__" section at the very conclusion of the book! (...a section readers often skip over). Not only is the section entertaining to read,

*BUT*in it are buried these innocuous, cryptic lines:

Leave it to Matt to concoct such a ploy! And I assume by "competition," he is"Oh yeah, and there is a competition hidden somewhere in this book. If anyone wins it, I'll think of a suitable prize. Beware of the traps."

*not*referencing proving the Riemann hypothesis! ;-). (The book poses various questions and problems at points, but I'm not sure what is being referred to as "a competition" or "the traps" -- could be fun going back through the pages trying to figure out what it's all about.)

Anyway, have at it, and, with this heads-up, may one of my readers win the prize!
