Richard Furman is a vascular surgeon with decades of experience. But his personal journey into living younger longer began with a tight pair of pants. Rather than go up a size, he decided to get back to his ideal weight. He changed how he ate. He began to exercise regularly. He started intensive research into what it takes to prevent the kind of conditions his patients had. What he found changed his life . . . and will change yours.Do you want to be healthy and active all of your life?Do you want to enjoy not just long life but quality life?Do you want to be there—wholly there—for your family and friends?Aging is inevitable, but heart disease, cancer, diabetes, dementia, stroke, erectile dysfunction, and other age- and obesity-related problems are not! Simple, sustainable changes you make today can mean the difference between enjoying time with friends and family, and wasting it in doctors’ offices and hospitals.

    

    This user-friendly self-study guide is aimed at the general reader who is motivated to tackle that not insignificant challenge. The book is written using straightforward and accessible language, with clear derivations and explanations as well as numerous fully solved problems. For those with minimal mathematical background, the first chapter provides a crash course in foundation mathematics. The reader is then taken gently by the hand and guided through a wide range of fundamental topics, including Newtonian mechanics; the Lorentz transformations; tensor calculus; the Einstein field equations; the Schwarzschild solution (which gives a good approximation of the spacetime of our Solar System); simple black holes and relativistic cosmology. Following the historic 2015 LIGO (Laser Interferometer Gravitational-Wave Observatory) detection, there is now an additional chapter on gravitational waves, ripples in the fabric of spacetime that potentially provide a revolutionary new way to study the universe. Special relativity helps explain a huge range of non-gravitational physical phenomena and has some strangely counter-intuitive consequences. These include time dilation, length contraction, the relativity of simultaneity, mass-energy equivalence and an absolute speed limit. General relativity, the leading theory of gravity, is at the heart of our understanding of cosmology and black holes.Understand even the basics of Einstein's amazing theory and the world will never seem the same again.

    It's for anyone who thinks big questions are worth talking about. To get us started, Douglas Groothuis unpacks seven pivotal sentences from the history of western philosophy--a few famous, all short, none trivial. Included are:• Socrates—The unexamined life is not worth living.• Augustine—You have made us for yourself, and our hearts are restless until they rest in you.• Descartes—I think, therefore I am.• Pascal—The heart has reasons, that reason knows nothing of.Protagoras, Aristotle and Kierkegaard round out this quick tour. Since every philosopher has a story, not just a series of ideas, Groothuis also offers a bit of each one's life to set the stage. The seven sterling sentences themselves, while they can't tell us all there is to know, offer bridges into other lands of thought which can spark new ideas and adventures. And who knows where they might lead?

    If the idea of a computer science book without computers upsets you, please close your eyes until you’ve finished reading the rest of this page.The truth is that computer science is not really about the computer. It is just a tool to help you see ideas more clearly. You can see the moon and stars without a telescope, smell the flowers without a fluoroscope, have fun without a funoscope, and be silly sans oscilloscope.You can also play with computer science without... you-know-what. Ideas are the real stuff of computer science. This book is about those ideas, and how to find them.

    There are classical logic puzzles, lateral thinking puzzles, “who am I?” riddles, mathematical brain teasers, word ladders, ditloids, and a large selection of illustrated pen and paper, coins, cups, and toothpicks puzzles (please view the preview of this book for a full listing). This is the first time a collection of such breadth has been compiled and formatted especially for Kindle devices. The puzzles have been carefully organized into 25 chapters, and each question is hyperlinked to its solution, to provide utmost ease of navigation. Alongside the world’s most famous riddles, are some lesser known gems, and some brand new puzzles, in print here for the first time. Our aim was to create a definitive compendium of riddles and puzzles to bring enjoyment to people of all ages. We hope you will enjoy unraveling them as much as we enjoyed creating and editing them. Here are a handful of sample riddles: Outside the Box Riddles: You need to divide a round birthday cake into eight pieces, so each of your guests will have something to eat. How can you do this by making only three straight cuts with a knife, and without moving any of the pieces? The king’s two bodyguards developed an ingenious method for assuring the king’s safety. With the king standing between them, they would face in opposite directions; one looking to the west and the other to the east, but at the same time, and without the use of any reflective surfaces, they would both be able to observe the king clearly. How was this possible? Pure Logic Riddles: There are two glasses. One contains water, and the other contains an equal quantity of wine. A teaspoon of water is removed and mixed into the glass of wine. A teaspoon of the wine-water mixture is then removed and mixed into the glass of water. Which of the mixtures is now purer? The sorcerer’s tower was enchanted in such a way that it was able to build itself. Bricks, slates, tiles, and panes of glass, all flew to it of their own accord and danced into position. The tower doubled in size every day until after 100 days it reached a height that provided fine views over the entire realm. How many days did the tower take to reach half its full height? Lateral Thinking Puzzles: Five men are going to church. It starts to rain, and four of the men begin to run. When they arrive at the church, the four men who ran are soaking wet, whereas the fifth man, who didn’t run, is completely dry. How is this possible? Think Twice Riddles: If you are running a race, and you overtake the person in second place, what place do you move into? Word Riddles: SOS is read the same forwards, backwards, and even upside-down. What four-letter word also shares these properties? Number Puzzlers: How many letters are there in the answer to this question? You have an opportunity to buy a hen. In fact, you have been offered a choice between two quite remarkable animals. One of the hens produces six dozen dozen eggs per month, and the other produces a half dozen dozen. Admittedly, both seem impressive. Does it matter which hen you choose? Traditional Poetic Riddles: Five creatures cross a field of snow; But leave a single track behind Whose loops and bows are soon, I know, Unravelled by the mind. Coins, Cups, and Toothpicks Illustrated Riddles: A coin is dropped into an empty bottle and a cork is then inserted in the neck of the bottle. How is it possible to remove the coin without taking out the cork, or breaking the bottle?

    Usually this involves doing what other people have overlooked, as well as avoiding what is unproductive.He identifies five talents as essential to effectiveness, and these can be learned; in fact, they must be learned just as scales must be mastered by every piano student regardless of his natural gifts. Intelligence, imagination and knowledge may all be wasted in an executive job without the acquired habits of mind that convert these into results. One of the talents is the management of time. Another is choosing what to contribute to the particular organization. A third is knowing where and how to apply your strength to best effect. Fourth is setting up the right priorities. And all of them must be knitted together by effective decision-making. How these can be developed forms the main body of the book. The author ranges widely through the annals of business and government to demonstrate the distinctive skill of the executive. He turns familiar experience upside down to see it in new perspective. The book is full of surprises, with its fresh insights into old and seemingly trite situations.
