Photothermal science continues to be an area of rapid development
and active investigation, as is demonstrated by this volume. The
various contributions present fundamental research in materials
science, physics, chemistry, biology, and medicine, as well as
important applications of photothermal techniques in nondestructive
evaluation, aeronomy and pollution control, and other areas. The
topics treated include measurements of spectral properties of
gases, the theory of thermally generated elastic waves, a method of
monitoring local surface displacements, materials characterization
and nondestructive evaluation of materials, studies of the dynamics
of primary photophysical processes, fast energy exchange at
surfaces and at interfaces (e.g. in medicine and photobiology),
thermal EXAFS and XANES applied to metals and semiconductors, and
imaging of magnetic materials using microwave sources.

Humans and snakes have an intimate and ancient relationship that
often revolves around either love or hate. Snakes can be seen as
gods, spiritual messengers, symbols of fertility, and guardians of
resources in virtually all cultures. But to those that fear them,
snakes are seen as venomous creatures that cannot be trusted. In
Secrets of the Snake Charmer, John Murphy, a research associate of
the Division of Amphibians and Reptiles in the Field Museum of
Natural History in Chicago, provides an in-depth, twenty-first
century look at snakes utilizing the published research of other
herpetologists as well as his own personal experiences and
speculations. Murphy covers a wide range of topics such as the
adaptability of snakes, the ways in which evolution has tinkered
with snakes during the last 160 million years, and the impact
snakes have on the ecological communities they live in. While
sharing ideas about the origin of snakes, rattlesnake rattles, and
spitting in cobras, Murphy presents an innovative portrayal of
snakes that proves they co-evolve with their prey, predators, and
parasites in order to fulfill a significant and novel role in the
web of life.
