Book Description
This paper describes a scheme to determine the size of the circular field of view that is both necessary and sufficient to include at least some specified number, n, of stars from a given set, independent of the orientation of the field within the celestial sphere. A geometrical proof of the scheme is presented, and all equations needed to effect the scheme are derived. The scheme is thus shown to be entirely analytical and to involve no assumptions concerning the distribution of the stars. Numerical results are presented in which the 1064 stars brighter than, or equal in brightness to, an apparent visual magnitude of +4.7 are considered. The size and location of the necessary fields of view are tabulated as a function of limiting star brightness for n=1, n=2, and n=3. Finally, the meaning and importance of the data are discussed and related to star sensor technology.

Book Description
In this book, Dr. Merriot takes her readers into the night Sky above the Bighorn Medicine Wheel to explore the scientific and supernatural elements of this National Historic Landmark and Sacred Site. Written for the adventurous, Ivy relates cultural and scientific stories, adding personal experiences and new findings from her own research based on Indigenous and Western Science astronomies. She concludes that the Wheel is a spectacularly designed and fitting "Place" to study the cosmos and encourages her readers to take a personal trip to the Bighorn Medicine Wheel and embark upon their own adventure with the stars.

Book Description
In Miletus, about 550 B.C., together with our world-picture cosmology was born. This book tells the story. In Part One the reader is introduced in the archaic world-picture of a flat earth with the cupola of the celestial vault onto which the celestial bodies are attached. One of the subjects treated in that context is the riddle of the tilted celestial axis. This part also contains an extensive chapter on archaic astronomical instruments. Part Two shows how Anaximander (610-547 B.C.) blew up this archaic world-picture and replaced it by a new one that is essentially still ours. He taught that the celestial bodies orbit at different distances and that the earth floats unsupported in space. This makes him the founding father of cosmology. Part Three discusses topics that completed the new picture described by Anaximander. Special attention is paid to the confrontation between Anaxagoras and Aristotle on the question whether the earth is flat or spherical, and on the battle between Aristotle and Heraclides Ponticus on the question whether the universe is finite or infinite.

Book Description
There is a need for comprehensive books that provide crucial information in a clear and direct manner, particularly in the medical field. Currently, there are limited resources available to students and clinicians that provide step-by-step procedures with pictures on how to examine the eye in the pediatric population. The Pediatric Eye Exam Quick Reference Guide: Office and Emergency Room Procedures is a clinical procedure book to provide step-by-step pediatric eye care examination techniques and is an important addition to the field of eye care. The chapters are written by leading pediatric optometrists and ophthalmologists in the field. Years of academic and clinical experiences from schools of optometry, hospital-based eye care, and private practice are all presented in a user-friendly format with clinical pearls and insights that will help any clinician perform a pediatric eye exam easily and efficiently. Covering a range of critical topics such as pupil examination, visual field testing, refraction, and ocular emergencies and providing pictures, it is ideal for all students, residents, academicians, trainers, and novel and seasoned clinicians who are interested in learning how to examine a pediatric patient and staying on top of the latest pediatric eye care procedures.
