    This introductory text is suitable for use in a course on the subject or for self-study, featuring broad coverage and a readable exposition, with many examples and exercises. The four main chapters present the basics: fundamental group and covering spaces, homology and cohomology, higher homotopy groups, and homotopy theory generally. The author emphasizes the geometric aspects of the subject, which helps students gain intuition. A unique feature is the inclusion of many optional topics not usually part of a first course due to time constraints: Bockstein and transfer homomorphisms, direct and inverse limits, H-spaces and Hopf algebras, the Brown representability theorem, the James reduced product, the Dold-Thom theorem, and Steenrod squares and powers.

    This book picks you up at the very beginning and guides you through the foundations of algebra using lots of examples and no-nonsense explanations.

    Just read this till the end You don’t have to buy this book. Just read this till end & you will learn something that will change the way you do math forever. Warning: I am revealing this secret only to the first set of readers who will buy this book & plan to put this secret back inside the book once I have enough sales. So read this until the very end while you still can.School taught you the wrong way to do mathThe way you were taught to do math, uses a lot of working memory. Working memory is the short term memory used to complete a mental task. You struggle because trying to do mental math the way you were taught in school, overloads your working memory. Let me show you what I mean with an example:Try to multiply the 73201 x 3. To do this you multiply the following:1 x 3 =0 x 3 =2 x 3 =3 x 3 =7 x 3 =This wasn’t hard, & it might have taken you just seconds to multiply the individual numbers. However, to get the final answer, you need to remember every single digit you calculated to put them back together. It takes effort to get the answer because you spend time trying to recall the numbers you already calculated. Math would be easier to do in your head if you didn’t have to remember so many numbers. Imagine when you tried to multiply 73201 x 3, if you could have come up with the answer, in the time it took you to multiply the individual numbers. Wouldn’t you have solved the problem faster than the time it would have taken you to punch in the numbers inside a calculator? Do the opposite of what you were taught in schoolThe secret of doing mental math is to calculate from left to right instead of from right to left. This is the opposite of what you were taught in school. This works so well because it frees your working memory almost completely. It is called the LR Method where LR stands for Left to Right.Lets try to do the earlier example where we multiplied 73201 x 3. This time multiply from left to right, so we get:7 x 3 = 213 x 3 = 93 x 2 = 60 x 3 = 03 x 1 = 3Notice that you started to call out the answer before you even finished the whole multiplication problem. You don’t have to remember a thing to recall & use later. So you end up doing math a lot faster. The Smart ChoiceYou could use what you learnt & apply it to solve math in the future. This might not be easy, because we just scratched the surface. I've already done the work for you. Why try to reinvent the wheel, when there is already a proven & tested system you can immediately apply.

    Covering various the materials needed by students in engineering, science, and mathematics, this calculus text makes effective use of computing technology, graphics, and applications. It presents at least two technology projects in each chapter.

    The calculus is not a hard subject and I prove this through an easy to read and obvious approach spanning only 100 pages. I have written this book with the following type of student in mind; the non-traditional student returning to college after a long break, a notoriously weak student in math who just needs to get past calculus to obtain a degree, and the garage tinkerer who wishes to understand a little more about the technical subjects. This book is meant to address the many fundamental thought-blocks that keep the average 'mathaphobe' (or just an interested person who doesn't have the time to enroll in a course) from excelling in mathematics in a clear and concise manner. It is my sincerest hope that this book helps you with your needs.Show more Show less

    It ranges over the changing lives of peasants, urban workers, and professionals; the interaction of Soviet autocrats with the people; the character and role of religion, law, education, and literature within Soviet society; and the significance and fate of various national groups. As the story unfolds, we come to understand how the ideas of Marxism have been changed, taking on almost unrecognizable forms by unique political and economic circumstances.Hosking's analysis of this vast and complex country begins by asking how it was that the first socialist revolution took place in backward, autocratic Russia. Why were the Bolsheviks able to seize power and hold on to it? The core of the book lies in the years of Stalin's rule: how did he exercise such unlimited power, and how did the various strata of society survive and come to terms with his tyranny?The later chapters recount Khrushchev's efforts to reform the worst features of Stalinism, and the unpredictable effects of his attempts within the East European satellite countries, bringing out elements of socialism that had been obscured or overlaid in the Soviet Union itself. And in the aftermath of the long Brezhnev years of stagnation and corruption, the question is posed: can Soviet society find a way to modify the rigidities inherited from the Stalinist past?

    Now, updated and expanded, this classic reference continues to bring to readers the full array of civilization's architectural achievements.Insightful, engagingly written and graced with close to a thousand superb illustrations, the Second Edition of this extraordinary volume offers a sweeping narrative that examines architecture as it reflects the social, economic, and technological aspects of human history. The scope of the book is astonishing. Kostof examines a surprisingly wide variety of man-made structures: prehistoric huts and the TVA, the pyramids of Giza and the Rome railway station, the ziggurat and the department store. Kostof considered every building worthy of attention, every structure a potential source of insight, whether it be prehistoric hunting camps at Terra Amata, or the caves at Lascaux with their magnificent paintings, or a twenty-story hotel on the Las Vegas Strip.

    Many teachers today must work two or more jobs to survive; they can't afford to buy homes or raise families. Why are they paid so poorly? How is this related to student achievement? And how can we find ways to treat them like the professionals they are?Teachers Have It Easy examines how bad policy interacts with teachers' lives. Interweaving teachers' voices from across the country with hard-hitting facts and figures, this book is a clear-eyed view of the harsh realities of public-school teaching, without any chicken-soup-for-the-soul success stories. With a look at the problems of recruitment and retention, the myths of short workdays and endless summer vacations, the realities of the workweek, and shocking examples of how America views its teachers. Teachers Have It Easy explores why salary reform may be the best way to improve public education and examines how innovative compensation plans can transform schools.
