  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.

  The Present Illness - American...

  Health care reform efforts are difficult to achieve and have been historically undermined by their narrow scope. In The Present Illness, Martin F. Shapiro, MD, PhD, MPH, weaves together history, sociology, extensive research, and his own experiences as a physician to explore the broad range of afflictions impairing US health care and explains why we won't be able to fix the system without making significant changes across society. With a sharp eye and ready humor, Shapiro dissects the ways all groups participating—clinicians and their organizations, medical schools and their faculty, hospitals and clinical corporations, scientists and the National Institutes of Health, insurers and manufacturers, governments and their policies, and also patients and the public—shape and reinforce a dysfunctional system. Shapiro identifies three major problems stymieing reform: commodification of care; values, expectations, unmet needs, attitudes, and personal limitations of participants; and toxic relationships and communication among these groups.Shapiro lays out a sweeping agenda of concrete actions to address the many factors contributing to the system's failings. Highlighting the interconnectedness of both the problems and potential solutions, he warns that piecemeal reform efforts will continue to be undermined by those who believe they have something to gain from the status quo. Although overhauling our health care system is daunting, Shapiro nonetheless concludes that we must push forward with a far more comprehensive effort in all sectors of health care and throughout society to create a system that is humane, effective, and just.

  Matter - The Magnificent Illusion

  Guido Tonelli

  What are we made up of? What holds material bodies together? Is there a difference between terrestrial matter and celestial matter? When Democritus stated that we are made up of atoms, few people believed him. Not until Galileo and Newton in the seventeenth century did people take the idea seriously, and it was another four hundred years before we could reconstruct the elementary components of matter. 
   
   
   
  Everything around us has very particular properties. These properties, which seem quite normal to us, are in fact very special, because the universe, whose evolution began almost fourteen billion years ago, is today a very cold environment. In this book, Guido Tonelli explains how elementary particles, which make up matter, combine into bizarre shapes to form correlated quantum states, primordial soups of quarks and gluons, or massive neutron stars. New questions that have emerged from the most recent research are answered: in what sense is the vacuum a material state? Why can space-time also vibrate and oscillate? Can elementary grains of space and time exist? What forms does matter assume inside large black holes? 
   
   
   
  In clear and lively prose, Tonelli takes listeners on an exhilarating journey into the latest discoveries of contemporary science, enabling them to see the universe, and themselves, in a new light.

  Tyrannosaurus Rex and...

  The massively popular 1990 novel Jurassic Park by Michael Crichton and its subsequent movie adaptations led to a huge resurgence in interest in dinosaurs and the prehistoric world. That interest continues to the present day, even though most of the dinosaurs in Jurassic Park weren’t actually from the Jurassic period. Triceratops, Velociraptor, Tyrannosaurus Rex and the huge sauropods such as Brachiosaurus that feature in the book and movies all actually belong to the Late Cretaceous period, more than 40 million years after the end of the Jurassic. Regardless, certain kinds of dinosaurs remain instantly recognizable, and among them, the “king” is undoubtedly the Tyrannosaurus.  
  The first discovery of a Tyrannosaurus was made in 1902 and the largest carnivorous dinosaur ever found at the time quickly gripped the popular imagination. Even its name was dramatic - Tyrannosaurus Rex means “King of the Tyrant Lizards.” The T-Rex as it quickly became known didn’t appear until the last age of the Late Cretaceous period, the Maastrichtian, but when it did, it was the biggest and most terrifying of all the theropod predators.  
  	Thanks to the movie, there has been some unwitting confusion over the identity of the Velociraptor, and this confusion was due in large part to the fact the name sounds far more scary than the creature to which the name originally belonged. Moreover, the creature to which the label was applied in the novel and movie was actually a distant cousin named Deinonychus, but as the story goes, the author, Michael Crichton, thought “Velociraptor” sounded “more dramatic.” The actual Velociraptor lived not in the badlands of North America, but in the badlands of central-eastern Asia, and it was not nearly as intimidating as Deinonychus. In fact, the main species of genus Velociraptor - Velociraptor mongoliensis - was no bigger than a turkey.
