M Theory Lesson 283

Whilst perusing the literature on Cayley's hyperdeterminant, I kept coming across a reference to the textbook by Gelfand, Kapranov and Zelevinsky. The library here does not have this book, but recently it occured to me that I might order it online. Imagine that! After only a week, a beautiful hard bound dark green copy arrived, well wrapped, from Ohio.

The front cover has a diagram that looks something like this: This is an example of a secondary polytope. In the section Examples of secondary polytopes, on page 237, we find the associahedra. I can't wait to read more.
