This book is a history of the development of mathematical astronomy in China, from the late third century BCE, to the early 3rd century CE - a period often referred to as 'early imperial China'. It narrates the changes in ways of understanding the movements of the heavens and the heavenly bodies that took place during those four and a half centuries, and tells the stories of the institutions and individuals involved in those changes. It gives clear explanations of technical practice in observation, instrumentation, and calculation, and the steady accumulation of data over many years - but it centres on the activity of the individual human beings who observed the heavens, recorded what they saw, and made calculations to analyse and eventually make predictions about the motions of the celestial bodies. It is these individuals, their observations, their calculations, and the words they left to us that provide the narrative thread that runs through this work. Throughout the book, the author gives clear translations of original material that allow the reader direct access to what the people in this book said about themselves and what they tried to do.

One of the most controversial, cutting-edge ideas in cosmology—the possibility that there exist multiple parallel universes—in fact has a long history. Tom Siegfried reminds us that the size and number of the heavens have been contested since ancient times. His story offers deep lessons about the nature of science and the quest for understanding.

"Why do I always see the numbers 444 (or 111, 333, etc.) everywhere I go?" is one of the most frequently asked questions that Doreen Virtue receives at her worldwide workshops. In her best-selling book Healing with the Angels, Doreen included a chapter that briefly explained the meanings behind these number sequences, and many people have commented that they carry the book with them everywhere to help them interpret the numbers they see daily. By popular request from Doreen’s audience members, Angel Numbers has been created to serve as a pocket guide containing the angelic meanings of numbers from 0 to 999. Designed to fit into a purse or pocket for easy transport, Angel Numbers provides an interpretation of more complex number sequences than was previously available in Healing with the Angels. This new book focuses on numbers such as 123, 337, 885, and so on. Whether you’re seeing these numbers on license plates, telephone numbers, the clock, or other locations, they’re very real messages from the angels. Angel Numbers will help you instantly understand the meaning of these signs!

Your Bible, your history books, and even your newspaper headlines are full of God shouting a powerful message of hope and healing. The same author who designed 24,900 miles around the planet, also calculated 24 hours around your clock, and predetermined 24 elders around the throne. But unless you know what God is consistently speaking through the number 24, you miss the message. In fact, you don't even know there is a message. Numbers That Preach is a fun look at the otherwise hidden sermons God is declaring through His mathematical lingo. For more than twenty years, author Troy Brewer has studied Biblical text and collected interesting facts, figures and statistics that show powerful meaning in the numbers around us.
