Excerpt from Practical Talks by an Astronomer The present volume has not been designed as a systematic treatise on astronomy. There are many excellent books of that kind, suitable for serious students as well as the general reader; but they are necessarily somewhat dry and unattractive, because they must aim at completeness. Completeness means detail, and detail means dryness. But the science of astronomy contains subjects that admit of detached treatment; and as many of these are precisely the ones of greatest general interest, it has seemed well to select several, and describe them in language free from technicalities.

One of the most brilliant observations of the last few years is Campbell's recent discovery of the triple character of this star. Centuries and centuries ago, when astronomy, that venerable ancient among the sciences, was but an infant, the pole-star must have been considered the very oldest of observed heavenly bodies. In the beginning it was the only sure guide of the navigator at night, just as to this day it is the foundation-stone for all observational stellar astronomy of precision. There has never been a time in the history of astronomy when the pole-star might not have been called the most frequently measured object in the sky of night. So it is indeed strange that we should find out something altogether new about it after all these ages of study. But the importance of the discovery rests upon a surer foundation than this. The method by which it has been made is almost a new one in the science. A generation ago, men thought the "perfect science," for so we love to call astronomy, could advance only by increasing a little the exact precision of observation. The citadel of perfect truth might be more closely invested; the forces of science might push forward step by step; the machinery of research might be strengthened, but that a new engine of investigation would be discovered capable of penetrating where no telescope can ever reach, this, indeed, seemed far beyond the liveliest hope of science. Even the discoverer of the spectroscope could never have dreamed of its possibilities, could never have foreseen its successes, its triumphs. The very name of this instrument suggests mystery to the popular mind. It is set down at once among the things too difficult, too intricate, too abstruse to understand. Yet in its essentials there is nothing about the spectroscope that cannot be made clear in a few words. Even the modern "undulatory theory" of light itself is terrible only in the length of its name. Anyone who has seen the waves of ocean roll, roll, and ever again roll in upon the shore, can form a very good notion of how light moves. 'Tis just such a series of rolling waves; started perhaps from some brilliant constellation far out upon the confining bounds of the visible universe, or perhaps coming from a humble light upon the student's table; yet it is never anything but a succession of rolling waves. Only, unlike the waves of the sea, light waves are all excessively small. We should call one whose length was a twenty-thousandth of an inch a big one!

In "The Destinies of the Stars," Svante Arrhenius embarks on an ambitious exploration of astrophysical phenomena and the fate of celestial bodies in the universe. This seminal work, notable for its scientific rigor and philosophical musings, is a cornerstone of early 20th-century astrophysics. Arrhenius employs a narrative style that intertwines empirical data with poetic reflection, providing readers with a multidimensional understanding of stellar life cycles and cosmic evolution. His insights into thermodynamics and energy transfer laid a crucial foundation for later developments in cosmology and planetary science. Svante Arrhenius, a Nobel laureate in Chemistry, was not only a pioneering scientist but also a visionary thinker who bridged multiple disciplines, from physical chemistry to meteorology. His profound interest in the interaction between matter and energy, along with his early work on the greenhouse effect, undoubtedly influenced his fascination with the stars and their transformation over eons. Arrhenius's rigorous scientific background allowed him to approach vast astronomical subjects with clarity and depth, engaging both the scientific community and the general public. This book is highly recommended for anyone with a passion for science and the universe. Arrhenius's unique blend of science and literature invites readers to contemplate the grandeur of the cosmos and our place within it. "The Destinies of the Stars" is essential reading for both amateur astronomers and scholars, offering timeless insights and inspiring thoughts that resonate with contemporary issues in astrophysics.

Almost all amateur astronomers want to take photographs of the night sky. For all but the simplest star-trail pictures, this involves machinery - a telescope drive - to track the stars, essential to compensate for the rotation of the earth. The task becomes even more complicated when photographing very small or very faint objects that require high magnification or very long exposure times. Amateurs have many options according to their requirements, technical ability, and budget. Astrophotography for Amateurs looks at all the possibilities, including normal ("wet") photography, CCD imaging, and modern techniques of computer enhancement. There are sections about photographing different classes of astronomical object from the Moon to faint nebulae, as well as a thorough look at the equipment needed.
