Statica en Dynamica

Before he passed away recently, my great uncle, Morris Kool, passed a couple ancestry items on to me. This one, “Statica en Dynamica,” is a real gem. My great-grandfather, Cornelis Kool, earned a doctorate (I believe in economics) and his thesis was this book from 1935. I’ll include some photos here of the cover, inscription, first few pages, and insert.
