This book is intended for undergraduates and young researchers who wish
to understand the role that different branches of physics and
mathematics play in the execution of actual experiments. The unique
feature of the book is that all the subjects addressed are strictly
interconnected within the context of the execution of a single
experiment with very high accuracy, namely the redetermination of the
Avogadro constant NA, one of the fundamental physical
constants. The authors illustrate how the basic laws of physics are
applied to describe the behavior of the quantities involved in the
measurement of NA and explain the mathematical reasoning and
computational tools that have been exploited. It is emphasized that all
these quantities, although pertaining to a specific experiment, are of
wide and general interest. The book is organized into chapters covering
the interaction of electromagnetic radiation with single crystals,
linear elasticity and anisotropy, propagation of thermal energy,
anti-vibration mounting systems, and data analysis and B-spline
interpolation. An essential feature is the focus on the role of
Mathematica, an invaluable, fully integrated software environment for
handling diverse scientific and technical computations.
