Göran Grimvall is determined to help mere mortals understand how scientists get to the kernel of perplexing problems. Entertaining and enlightening, his latest book uses examples from sports, literature, and nature -- as well as from the varied worlds of science -- to illustrate how scientists make sense of and explain the world around us. Grimvall's funtoread essays and easytofollow examples detail how orderofmagnitude estimation, extreme cases, dimensional analysis, and other modeling methods work. They also reveal how nonscientists absorb these concepts and use them at home, school, and work. Grimvall's simple, elegant explanations will help you tap into your inner scientist. Read this book and enjoy your own ''Aha!'' moment.
