Review Not since Lewis Carroll wrote about logic has an expert produced a textbook on logic so saturated with delightful problems, paradoxes, jokes, and philosophical implications as Professor Smullyan's Logical Labyrinths . Opening with a superb assortment of his famous logic puzzles, Ray moves sure-footed through higher-order logics to the paradise of Cantor's alephs and Gödel s undecidables. If you've ever wondered why in first-order logic the statement All unicorns have five legs is assumed true, Smullyan will make it all clear. It's a volume only Ray could have written, and it will be used in college classrooms for a long time to come.

legend
In this uplifting memoir, famous Japanese pop culture “King of the Geeks” Toshio Okada tells of the diet and lifestyle changes he made in his fight against obesity, and how his public perception dramatically improved as a result of his healthier appearance. Okada lost 110lbs in one year, without the use of funky dieting techniques or exercises, using nothing but a notepad. He recognized that a diet is doomed to fail if it’s unsustainable, and a person cannot continue something they do not enjoy. Examining various diets and exercise regimes—even considering surgery—he concluded that a recording diet would be the most effective method. By succeeding in the recording diet, a person will learn a means of self-control that can be applied to other aspects of life, such as budgeting. Toshio Okada’s diet reflects the six stages of space flight, each stage a little bit closer to the final goal of health and self confidence!
