  Why 1 in 4 nurses fail the PCCN exam on their first try (and what you can do differently)... 
  Success on the PCCN exam requires more than just rote memorization or sharp test-taking skills. 
    
  It requires strategy. A systematic approach that helps you break down and translate each question into familiar terms, so you can make full use of your clinical judgment and silence exam anxiety. 
    
  This book provides you with that strategy. 
     
  Inside, you’ll discover: 
    
  ●     A simple 4-step approach that lets you dissect each question on the exam and narrow down your options by tapping into your clinical expertise 
  ●     Which biological systems and diseases make up the most significant portion of the exam 
  ●     The core components of the AACN’s Synergy Model, and which aspects you’re likely to be tested on 
  ●     What to know before you start studying — this is vital to helping you squeeze the most out of your study prep 
  ●     Three full-length practice test that includes 125 unique questions and detailed answer explanations, plus 50 extra practice questions to help reinforce your knowledge for each section on the PCCN 
    
  And much more! 
    
  By the end, you’ll know what to expect on every section of the exam, including the most critical points many nurses forget about.

  Impossible? - Surprising...

  In Nonplussed!, popular-math writer Julian Havil delighted readers with a mind-boggling array of implausible yet true mathematical paradoxes. Now Havil is back with Impossible?, another marvelous medley of the utterly confusing, profound, and unbelievable—and all of it mathematically irrefutable.Whenever Forty-second Street in New York is temporarily closed, traffic doesn't gridlock but flows more smoothly—why is that? Or consider that cities that build new roads can experience dramatic increases in traffic congestion—how is this possible? What does the game show Let's Make A Deal reveal about the unexpected hazards of decision-making? What can the game of cricket teach us about the surprising behavior of the law of averages? These are some of the counterintuitive mathematical occurrences that readers encounter in Impossible?Havil ventures further than ever into territory where intuition can lead one astray. He gathers entertaining problems from probability and statistics along with an eclectic variety of conundrums and puzzlers from other areas of mathematics, including classics of abstract math like the Banach-Tarski paradox. These problems range in difficulty from easy to highly challenging, yet they can be tackled by anyone with a background in calculus. And the fascinating history and personalities associated with many of the problems are included with their mathematical proofs. Impossible? will delight anyone who wants to have their reason thoroughly confounded in the most astonishing and unpredictable ways.

  The Human Gene Editing Debate

  John H. Evans

  In 2018 the first genetically modified babies were reportedly born in China, made possible by the invention of CRISPR technology in 2012. This controversial advancement overturned the pre-existing moral consensus, which had held for over fifty years before: while gene editing an adult person was morally acceptable, modifying babies, and thus subsequent generations, crossed a significant moral line. If this line is passed over, scientists will be left without an agreed-upon ethical limit. What do we do now? 
   
   
   
  John H. Evans here provides a meta-level guide to how these debates move forward and their significance to society. He explains how the bioethical debate has long been characterized as a slippery slope, with consensually ethical use at the top, nightmarish dystopia at the bottom, and specific agreed-upon limits in between, which draw the lines between the ethical and the unethical. Evans frames his analysis around these limits, or barriers. He examines the history of how barriers were placed, then fell, then replaced by new ones, and discusses how these insights inform where the debate may head. He evaluates other proposed barriers relevant to where we are now, projects that most of the barriers suggested by scientists and bioethicists will not hold, and cautiously identifies a few that could serve as the moral boundary for the next generation.

  Spaced Out - A Casual Approach...

  Spaced Out is designed to give a brief overview on all of the subjects that pertain to astronomy and space sciences in a down-to-Earth way.  
  It is inspired by current space news and the most asked questions from popular science communicator Kalpana Pot’s online audience.  
  The subjects covered include our solar system, stars, galaxies, exoplanets, telescopes, spacetime, interstellar objects, relativity, quantum mechanics, debunking conspiracies, and the unknown.  
  Each page covers one specific concept that fits into the above categories. This gives the readers a general take on rather complex topics.  
  Readers are further encouraged to do their own deep-dive on the topics that interest them the most. 
  The more we learn about the Universe, the more we realize how much we don’t know. Discoveries that challenge what we once thought we knew happen all the time. This book is accurate for the time of the writing, but things can always change, and that’s what’s most exciting about science in general!  
  Space is for everyone. You’re never too old, too young, too uneducated, or even too busy to slow down and ponder the final frontier.

  CHARGE - Why Does Gravity Rule?

  Frank Close

  Humans have long been aware of the electric and magnetic forces around us, and scientific investigation showed that the two are intimately connected as electromagnetism. Lightning shows how devastating electricity can be in nature, while humans learned to exploit the flow of negatively charged electrons that make up an electric current. In the early twentieth century, the experiments of Ernest Rutherford showed that at the heart of atoms lies a positively charged nucleus. The positive charge comes from protons. Atoms are neutral because the charges of the electron and proton cancel out. 
   
   
   
  The charges of the proton and electron are opposite and equal, even though the proton is bigger. But why are they equal? This is one of the deepest unresolved puzzles of physics. Frank Close takes us on a journey into the quantum subatomic world of particles. He describes the strong and weak forces that operate alongside electromagnetism, the color and flavor charges, as well as the parallels between them, giving hints of a deeper unity. Seeking an answer to why matter is neutral brings us to fundamental forces and particles, the Standard Model, the Higgs boson, and implications of grand unification for the stability of matter. Close packs in a rich account of our current understanding and the latest ambitious experiments to probe further, and test theoretical possibilities.
