This volume was developed from a symposium
dedicated to Jack McIntosh presented at the
2001 Society of Vertebrate Paleontology annual
meeting, which we convered with Dan Chure.
We thank Jack McIntosh for allowing us to
organize a symposium in his honor. We also
thank the participants of that symposium, most
of whom authored chapters in this volume, for
their excellent papers and patience throughout
the process of bringing this book to publication.
We especially thank Blake Edgar (UC Press) for
initially supporting this project and his continual
This chapter list the steps involved in preparing animal tissue for microscopic viewing; list several structural and functional characteristics of epithelial tissue; name, classify, and describe the various types of epithelia, and indicate their chief function(s) and location(s).
Tools shape how we think; when the only tool you have is an axe, everything resembles a
tree or a log. The rapid advances in instrumentation in the last decade, which allow us to
measure and manipulate individual molecules and structures on the nanoscale, have caused
a paradigm shift in the way we view molecular behavior and surfaces. The microscopic details
underlying interfacial phenomena have customarily been inferred from in situ measurements
of macroscopic quantities. Now we can see and “finger” physical and chemical
processes at interfaces.
Classical physics breaks down to the level of atoms and molecules. This was made
possible by the invention of a new apparatus that enabled the introduction of
measurements in microscopic area of physics. There were two revolutions in the way
we viewed the physical world in the twentieth century: relativity and quantum
mechanics. Quantum mechanics was born in 1924, through the work of Einstein,
Rutherford and Bohr, Schrödinger and Heisenberg, Born, Dirac, and many others. The
principles of quantum mechanics that were discovered then are the same as we know

"1_1_8"CHAPTER VIII. CONCENTRATION IN DELIVERY
Attention is the microscope of the mental eye. Its power may be high or low; its field of view narrow or broad. When high power is used attention is confined within very circumscribed limits, but its action is exceedingly intense and absorbing. It sees but few things, but these few are observed "through and through" ... Mental energy and activity, whether of perception or of thought, thus concentrated, act like the sun's rays concentrated by the burning glass. The object is illumined, heated, set on fire.
Perhaps quantum mechanics is viewed as the most remarkable development in 20th century physics. Each successful theory is exclusively concerned about "results of measurement". Quantum mechanics point of view is completely different from classical physics in measurement, because in microscopic world of quantum mechanics, a direct measurement as classical form is impossible. Therefore, over the years of developments of quantum mechanics, always challenging part of quantum mechanics lies in measurements.
In 1959, Richard P. Feynman, Professor of Physics at the California Institute of
Technology and Nobel Laureate, delivered an address at the American Physical
Society, which is given the credit for inspiring the field of nanotechnology. Published
in Engineering and Science, Feynman’s address entitled “Plenty of Room at the
Bottom” described a new field of science dealing with “the problem of manipulating
and controlling things on a small scale.
he Group A β-hemolytic streptococcus (Streptococcus pyogenes, or GAS) is a form of β-hemolytic Streptococcus bacteria. It is a gram positive bacteriaum responsible for a wide range of both invasive and non-invasive infections. The name derives from the greek word 'streptos,' meaning 'twisted chain,' due to the fact that the bacteria resembles a string of small pearls when viewed under the microscope
