Chronologically organized by epoch, this poetic introduction to the dinosaur world illuminates a host of creatures both novel and familiar, ranging from the mysterious trilobite to the famed Tyrannosaurus rex. Includes dinosaur facts.

"The stark, cold landscapes of Earth''s poles may seem inhospitable, but their snowy hollows and glacial waters hide an astounding variety of creatures, from the tiny, fascinating tardigrade to the mysterious giant squid, from the fleet-footed Arctic hare to the majestic polar bear. ... David Elliott turns his eye--and his pen--to the Arctic and Antarctic with lively poems filled with humor, admiration, and love"--

The mathematical theory of control became a ?eld of study half a century ago in attempts to clarify and organize some challenging practical problems and the methods used to solve them. It is known for the breadth of the mathematics it uses and its cross-disciplinary vigor. Its literature, which can befoundinSection93ofMathematicalReviews,wasatonetimedominatedby the theory of linear control systems, which mathematically are described by linear di?erential equations forced by additive control inputs. That theory led to well-regarded numerical and symbolic computational packages for control analysis and design. Nonlinear control problems are also important; in these either the - derlying dynamical system is nonlinear or the controls are applied in a n- additiveway.Thelastfourdecadeshaveseenthedevelopmentoftheoretical work on nonlinear control problems based on di?erential manifold theory, nonlinear analysis, and several other mathematical disciplines. Many of the problems that had been solved in linear control theory, plus others that are new and distinctly nonlinear, have been addressed; some resulting general de?nitions and theorems are adapted in this book to the bilinear case.
