This book is a superposition of two distinct narratives: the first is historical, discussing the evolution of astronomical knowledge since the dawn of civilizations; the second is scientific, conveying mathematical and physical content of each advancement. Great scientists of antiquity, Middle Ages and modern times until the 18th century, are presented along with their discoveries, through short biographies and anecdotes. Special care is taken to explain their achievements using mathematical and physical concepts of their time, with modern perspective added only when ancient methodology is too cumbersome or its language hardly understandable to contemporary readers.The book conveys a lot of astronomical facts and data in a pleasant and accessible manner. Almost all findings and discoveries made in ancient times are followed by simple mathematical exercises using basic knowledge, so that the reader can check the assertions himself. The book contains a lot of inedited illustrations. Geometrical schemes are given extra attention to make the examples clear and understandable. The language is simple and accessible to the young audience.

A real-world guide for adapting to the new energy era The Energy Disruption Triangle is a treatise on the energy revolution's real-world impacts, and a handbook for anyone looking to weather the storm. Three major technologies are already changing the energy paradigm: solar energy, electric vehicles, and energy storage. As technology continues to evolve and become more accessible to the masses, the nation's energy habits will experience a dramatic upheaval; this book provides actionable guidance to help you adapt. We are already in the beginning stages of this black swan event, and most people don't know what's coming—but it will come much sooner and much faster than anyone thinks. This book reveals the revolution happening right before our eyes, and shows you how to thrive in this new era. Learn how our energy supplies—and usage—are changing Understand why energy storage matters, and how the technology is evolving Explore the history and future of groundbreaking energy technologies Delve into the disruption of the U.S. energy supply, and the possibility of energy independence Rapidly advancing battery technology is boosting energy storage for homeowners, utilities, and electric vehicle manufacturers, stranding fossil fuels in the ground due to the high price of extraction relative to cost-effective sources such as solar and wind. Traditional energy sources are being phased out, and our nation has come to a fork in the road: uphold the status quo and allow our energy supply to be disrupted, or adapt and advance to a state of total energy independence. The Energy Disruption Triangle explores the state of U.S. energy from source to consumer, and provides insight into the three sectors that are changing the world.

A sacred light grid surrounds Table Mountain -- a network of sacred springs, caves, stone giants and geometrically aligned marker-stones. Some have human faces with their eyes aligned to interact with the cardinal directions of the sun, the Solstices and Equinoxes. Who did this and why? What message do they hold for us? Following the pathways of the sun through the eyes of ancient peoples, we discover the antiquity of the human spirit and the interconnectedness of all things. The book takes one on a colourful journey of rediscovery. It has been designed so that readers (of all ages) can open it at any page and be drawn into the journey through the magical pathway and photographs that weave the book together.

Details the science behind the Copernican Revolution, the transition from the Earth-centered cosmos to a modern understanding of planetary orbits.

This book offers the Greek text and an English translation of Aristarchus of Samos’s On the Sizes and Distances of the Sun and Moon, accompanied by a full introduction, detailed commentary, and relevant scholia. Aristarchus of Samos was active in the third century BC. He was one of the first Greek astronomers to apply geometry to the solution of astronomical problems as we can see in his only extant text, On the Sizes and Distances of the Sun and Moon. Alongside the Greek text and new English translation, the book offers readers the Latin text and English translation of Commandino’s notes on the text. Readers will also benefit from a comprehensive introductory study explaining the value of Aristarchus’s calculations and methodology throughout history, as well as detailed analyses of each part of the treatise. This volume will be of interest to students and scholars working on ancient science and astronomy and the general reader interested in the history of science.

Renewable energy is a critical topic of discussion in contemporary society. With increased attention on alternative methods, solar tracking has emerged as an effective strategy for sustainable energy management. Economical and Technical Considerations for Solar Tracking: Methodologies and Opportunities for Energy Management is an essential reference source for the latest scholarly research on economic and technical considerations of long-term and short-term solar tracking. Featuring coverage on a broad range of topics such as sun position, solar radiation, and geographic orientation, this publication is ideally designed for students, professionals, and engineers seeking current research on efficient use of solar energy.
