My goal in this book is to show the different types of UFOs reported throughout history and today. I’m not trying to prove whether these ships are real or not. I just thought that given the many thousands of sightings of UFOs there should be some commonalities between the sightings. Some of the questions I want to answer include: Are there any trends in these sightings? Is there an evolution in the design of these vehicles over time? Are there some common designs over time? Also, some of the UFOs sighted are likely fakes or secret projects built by the US government. I tried to show that information too. Just due to the number of stars in our galaxy I’m convinced that Aliens exist and have probably visited our planet thousands or even millions of year in the past-in addition to visiting in the present. This collection of historical photos, drawings, and descriptions should provide you with a narrative as to how these sightings have changed over time.Show book
This book explains the properties for each type of spring, plus essential materials and methods. Few mechanical devices are entirely devoid of springs of one sort or another, but satisfactory operation rests on details such as spring strength and degree of movement. Yet information on calculating and making springs is not easily available. Designing springs can be difficult due to the number of variables and the complexity of the formula. The book also introduces the designer to charts and nomograms, which greatly simplify the process. Topics include tension and compression spring principles, compression and spring design, examples for winding coil springs, how to design, make, and coil a leaf spring, torsion spring, and I.C. engine valve springs.Show book
Have you ever wondered if there are seasons on the moon or if space tourism will ever become commonplace? So has Dr. Maggie Aderin-Pocock. In fact, she earned her nickname “Lunatic” because of her deep fascination for all things lunar. In her lucidly written, comprehensive guide to the moon, Aderin-Pocock takes listeners on a journey to our closest celestial neighbor, exploring folklore, facts, and future plans. She begins with the basics, unpacking everything from the moon’s topography and composition to its formation and orbit around the Earth. She travels back in time to track humanity’s relationship with the moon—beliefs held by ancient civilizations, the technology that allowed for the first moon landing, a brief history of moongazing, and how the moon has influenced culture throughout the years—and then to the future, analyzing the pros and cons of continued space travel and exploration. The Book of the Moon will be published for the 50th anniversary of the moon landing. Includes an interview with the author.Show book

One man’s journey from doctor to patient to healer. Second Lives is a first-hand account of neurologist Ralph Lilly’s recovery from a traumatic brain injury and how the lessons of his recovery enabled him to help others with their own recoveries. “Discharged from a hospital just means you’re not dead.” These words of Ralph B. Lilly, M.D., describe his early struggle to recover from a traumatic brain injury. Lilly was a forty-four-year-old practicing neurologist sitting on his motorcycle at a red light when a drunk driver rear-ended him in 1980. In the ICU, after regaining consciousness and being told what happened, he asked, “What’s a hospital? What’s a motorcycle?” This tragic experience transformed his life and his approach to his neurology practice: doctors treat those with brain injury; but loved ones heal them. Second Lives: The Journey of Brain Injury Survivors and Their Healers is written by Dr. Lilly and Diane F. Kramer. After his death in 2021, Kramer completed the book with the assistance of Lilly’s wife, Joyce Stamp Lilly. This memoir weaves together Ralph Lilly’s experience with a collage of stories about his patients and their healers. After his recovery, Lilly retrained in the emerging field of behavioral neurology, which focuses on behavior, memory, cognition, and emotion after brain injury.Show book
