The $3x+1$ problem, or Collatz problem, concerns the following seemingly innocent arithmetic procedure applied to integers: If an integer $x$ is odd then “multiply by three and add one”, while if it is even then “divide by two”. The $3x+1$ problem asks whether, starting from any positive integer, repeating this procedure over and over will eventually reach the number 1. Despite its simple appearance, this problem is unsolved. Generalizations of the problem are known to be undecidable, and the problem itself is believed to be extraordinarily difficult. This book reports on what is known on this problem. It consists of a collection of papers, which can be read independently of each other. The book begins with two introductory papers, one giving an overview and current status, and the second giving history and basic results on the problem. These are followed by three survey papers on the problem, relating it to number theory and dynamical systems, to Markov chains and ergodic theory, and to logic and the theory of computation. The next paper presents results on probabilistic models for behavior of the iteration. This is followed by a paper giving the latest computational results on the problem, which verify its truth for $x < 5.4 cdot 10^{18}$. The book also reprints six early papers on the problem and related questions, by L. Collatz, J. H. Conway, H. S. M. Coxeter, C. J. Everett, and R. K. Guy, each with editorial commentary. The book concludes with an annotated bibliography of work on the problem up to the year 2000.

“Richly detailed. . . an intimate portrait of a diplomat.” —New Yorker From the seven-time New York Times bestselling author and former Secretary of State Madeleine Albright—among history's most admired and tireless public servants—a revealing, funny, and inspiring reflection on the challenge of continuing one’s career far beyond the normal age of retirement In 2001, when Madeleine Albright was leaving office as America’s first female secretary of state, interviewers asked her how she wished to be remembered. “I don’t want to be remembered,” she answered. “I am still here and have much more I intend to do. As difficult as it might seem, I want every stage of my life to be more exciting than the last.” In that time of transition, the former Secretary considered the possibilities: she could write, teach, travel, give speeches, start a business, fight for democracy, help to empower women, campaign for favored political candidates, spend more time with her grandchildren. Instead of choosing one or two, she decided to do it all. For nearly twenty years, Albright was in constant motion, navigating half a dozen professions, clashing with presidents and prime ministers, learning every day. After leaving the State Department, she blazed her own trail—and gave voice to millions who yearned for respect, regardless of gender, background, or age. Hell and Other Destinations reveals this remarkable figure at her bluntest, funniest, most intimate, and most serious. It is the tale of our times anchored in lessons for all time, narrated by an extraordinary woman who had a matchless zest for life.

This book contains short and concise exercises for use in a warm-up before practice or performance, and for general technical advancement. The book is divided into four sections: I Arpeggios, II Scales, III Tremolo, and IV Slurs. Each section contains a description of the exercises and general instructions on how to play them. The exercises are intended for guitarists who are looking for a simple warm-up that does not require learning many complicated etudes, exercises or routines. In this book, only one etude is used for a variety of arpeggio and tremolo patterns. The scale warm-ups are based on a two-octave, one-position scale that is shifted up and down the fretboard, and a simple one-position chromatic scale. The pull-off and hammer-on slurs are combined into one exercise to save time. This same routine, when practiced with the metronome gradually increasing the tempo, can also double for technical work. With the exception of one chromatic scale exercise, the rest are on closed strings. Besides being able to move the scale up and down the fretboard, the first finger can be barred. This will increase the left hand difficulty and improve the left hand position and strength.There is close to an hour's worth of material if all the exercises are played with all of their variations at different tempos. Not everything needs to be played everyday, so the warm-up session can be as long as desired or as short as time allows.
