  The practice of fixed prosthodontics has undergone many changes in recent times with significant developments in dental materials and principles of adhesion. However, tooth preparation is still guided by the need to preserve tooth tissue, generate space for restorative material and reshape the tooth to a cylindrical form with a defined finish line. This book carries these principles as a common theme and delineates the stages of prosthesis construction.

  Everything we know about how planets form and how life arises suggests that human civilization on Earth should not be unique. We ought to see abundant evidence of extraterrestrial activity—but we don't. Where is everybody? In this volume in the MIT Press Essential Knowledge series, science and technology writer Wade Roush examines one of the great unsolved problems in science: is there life, intelligent or otherwise, on other planets? 
   
   
   
  This paradox (they're bound to be out there; but where are they?), first formulated by the famed physicist Enrico Fermi, has fueled decades of debate, speculation, and, lately, some actual science. Roush lays out the problem in its historical and modern-day context and summarizes the latest thinking among astronomers and astrobiologists. He describes the long history of speculation about aliens; the emergence of SETI (the Search for Extraterrestrial Intelligence) as a scientific discipline in the 1960s, and scientists' use of radio and optical techniques to scan for signals; and developments in astrobiology and exoplanet research. Finally, he discusses possible solutions to the Fermi Paradox and suggests way to refocus SETI work that might increase the chances of resolving the paradox—and finding extraterrestrials.

  Physics

  Aristotle

  For many centuries, Aristotle's Physics was the essential starting point for anyone who wished to study the natural sciences. Aristotle deals with many abstract ideas in this book, examining the phenomenon of being, space, motion, matter, time, infinity, magnitude, and more. This book is basically an explanation on how the universe works--as Aristotle understood it. It's not so much a straight forward philosophical text as it is a sort of compendium of problems that philosophers have spent the past several millenniums trying to figure out. As a book of philosophy, it seems more concerned with creating a system where these sorts of questions can be fully articulated and worked on than it is in fully solving any of them.
