The Pulitzer Prize-winning columnist's "astonishing" and "enthralling" New York Times bestseller and Notable Book about how the Founders' belief in natural rights created a great American political tradition (Booklist) -- "easily one of the best books on American Conservatism ever written" (Jonah Goldberg). For more than four decades, George F. Will has attempted to discern the principles of the Western political tradition and apply them to America's civic life. Today, the stakes could hardly be higher. Vital questions about the nature of man, of rights, of equality, of majority rule are bubbling just beneath the surface of daily events in America. The Founders' vision, articulated first in the Declaration of Independence and carried out in the Constitution, gave the new republic a framework for government unique in world history. Their beliefs in natural rights, limited government, religious freedom, and in human virtue and dignity ushered in two centuries of American prosperity. Now, as Will shows, conservatism is under threat -- both from progressives and elements inside the Republican Party. America has become an administrative state, while destructive trends have overtaken family life and higher education. Semi-autonomous executive agencies wield essentially unaccountable power. Congress has failed in its duty to exercise its legislative powers. And the executive branch has slipped the Constitution's leash. In the intellectual battle between the vision of Founding Fathers like James Madison, who advanced the notion of natural rights that pre-exist government, and the progressivism advanced by Woodrow Wilson, the Founders have been losing. It's time to reverse America's political fortunes. Expansive, intellectually thrilling, and written with the erudite wit that has made Will beloved by millions of readers, The Conservative Sensibility is an extraordinary new book from one of America's most celebrated political writers.
Two dramatically different philosophical approaches to classical mechanics were proposed during the 17th - 18th centuries. Newton developed his vectorial formulation that uses time-dependent differential equations of motion to relate vector observables like force and rate of change of momentum. Euler, Lagrange, Hamilton, and Jacobi, developed powerful alternative variational formulations based on the assumption that nature follows the principle of least action. These variational formulations now play a pivotal role in science and engineering.This book introduces variational principles and their application to classical mechanics. The relative merits of the intuitive Newtonian vectorial formulation, and the more powerful variational formulations are compared. Applications to a wide variety of topics illustrate the intellectual beauty, remarkable power, and broad scope provided by use of variational principles in physics.The second edition adds discussion of the use of variational principles applied to the following topics:(1) Systems subject to initial boundary conditions(2) The hierarchy of related formulations based on action, Lagrangian, Hamiltonian, and equations of motion, to systems that involve symmetries.(3) Non-conservative systems.(4) Variable-mass systems.(5) The General Theory of Relativity.Douglas Cline is a Professor of Physics in the Department of Physics and Astronomy, University of Rochester, Rochester, New York.
Often considered a lost decade, a pause between the liberal Sixties and Reagan’s Eighties, the 1970s were indeed a watershed era when the forces of a conservative counter-revolution cohered. These years marked a significant moral and cultural turning point in which the conservative movement became the motive force driving politics for the ensuing three decades. Interpreting the movement as more than a backlash against the rampant liberalization of American culture, racial conflict, the Vietnam War, and Watergate, these provocative and innovative essays look below the surface, discovering the tectonic shifts that paved the way for Reagan’s America. They reveal strains at the heart of the liberal coalition, resulting from struggles over jobs, taxes, and neighborhood reconstruction, while also investigating how the deindustrialization of northern cities, the rise of the suburbs, and the migration of people and capital to the Sunbelt helped conservatism gain momentum in the twentieth century. They demonstrate how the forces of the right coalesced in the 1970s and became, through the efforts of grassroots activists and political elites, a movement to reshape American values and policies. A penetrating and provocative portrait of a critical decade in American history, Rightward Bound illuminates the seeds of both the successes and the failures of the conservative revolution. It helps us understand how, despite conservatism’s rise, persistent tensions remain today between its political power and the achievements of twentieth-century liberalism.
Dark Matter, Dark Energy and Dark Gravity make life possible!This book for the lay reader provides a summary of the latest astrophysical observational results and theoretical insights into what we know and what we hope to learn about dark matter, dark energy, and dark gravity.How did the profound beauty of our Earth, our Solar System, our Milky Way galaxy and indeed our universe unfold? Dark matter, dark energy, and dark gravity have made all the difference in how the universe has developed, and have been key to creating the overall environment that makes life possible. We have only recently developed the ability to begin unlocking their secrets, thus providing a deeper insight into how a universe of our type is possible. It seems that because of dark matter, dark energy and dark (weak) gravity, our universe has the right attributes for the development of complex structure and the evolution of intelligent life that can engage in the quest to understand our world. These "dark" or more hidden attributes of the cosmos have very good outcomes.In particular, the existence of dark matter makes it easier to form complex structures, including galaxies, stars and planets through gravitational collapse of denser regions of the universe. Planets are the most suitable abodes for the development of life. Dark energy acts to extend the lifetime of the universe by counteracting gravity and driving continued expansion of the universe.Even as far back as the 1930s there has been evidence that most of the matter in the universe was not visible via electromagnetic radiation (optical light, radio waves, etc.). By the last few decades of the 20th century, the case for a considerable amount of this dark matter was very strong. It is the second largest contributor to the total mass-energy of the universe. We don't know what it is and there are various candidates to explain it; nevertheless we see the gravitational effects of dark matter everywhere on the largest scales. Recent observational results indicate that dark matter dominates by a factor of 6 relative to the ordinary matter that makes up stars, planets, and living things.We now know that the major contributor to the mass-energy of the universe is not the substantial dark matter, but the 'newer' so-called dark energy. Dark energy acts to some extent as a negative gravity, and for the last several billion years has driven the expansion of the universe to a faster and faster pace, overcoming even the gravitational effect of dark matter. We have a general idea that it is the irreducible energy found in every volume of space, even in the absence of matter - in the vacuum. We don't understand why it takes the value that it does, one that is small in quantum particle physics terms, but nevertheless is of great significance on the large cosmological scale of the universe. The third important aspect to consider is not a mass-energy component, but the nature of gravity and space-time. The big question here is - why is gravity so relatively weak, as compared to the other 3 forces of nature? These 3 forces are the electromagnetic force, the strong nuclear force, and the weak nuclear force. Gravity is different - it has a dark or hidden side. It may very well operate in extra dimensions beyond the normal 4 dimensions of space-time that we can observe. This is what we mean in this book by "dark gravity".
A provocative biography of Edmund Burke, the underappreciated founder of modern conservatism Edmund Burke is both the greatest and the most underrated political thinker of the past three hundred years. A brilliant 18th-century Irish philosopher and statesman, Burke was a fierce champion of human rights and the Anglo-American constitutional tradition, and a lifelong campaigner against arbitrary power. Once revered by an array of great Americans including Presidents Theodore Roosevelt and Woodrow Wilson, Burke has been almost forgotten in recent years. But as politician and political philosopher Jesse Norman argues in this penetrating biography, we cannot understand modern politics without him. As Norman reveals, Burke was often ahead of his time, anticipating the abolition of slavery and arguing for free markets, equality for Catholics in Ireland, responsible government in India, and more. He was not always popular in his own lifetime, but his ideas about power, community, and civic virtue have endured long past his death. Indeed, Burke engaged with many of the same issues politicians face today, including the rise of ideological extremism, the loss of social cohesion, the dangers of the corporate state, and the effects of revolution on societies. He offers us now a compelling critique of liberal individualism, and a vision of society based not on a self-interested agreement among individuals, but rather on an enduring covenant between generations. Burke won admirers in the American colonies for recognizing their fierce spirit of liberty and for speaking out against British oppression, but his greatest triumph was seeing through the utopian aura of the French Revolution. In repudiating that revolution, Burke laid the basis for much of the robust conservative ideology that remains with us to this day: one that is adaptable and forward-thinking, but also mindful of the debt we owe to past generations and our duty to preserve and uphold the institutions we have inherited. He is the first conservative. A rich, accessible, and provocative biography, Edmund Burke describes Burke's life and achievements alongside his momentous legacy, showing how Burke's analytical mind and deep capacity for empathy made him such a vital thinker-both for his own age, and for ours.thread on pub day of what people at basic like about it (editors) "You won't find a more impressive political philosopher than the 18th-century MP who more or less invented Anglosphere conservatism. And you won't find a pithier, more readable treatise on his life and works than this one." --Wall Street Journal

Conservatism in America, as one early twentieth-century politician said, is “as old as the Republic itself.” But what are its foundational principles, and how did they form the modern conservative movement? Author Garland S. Tucker III tells the story in this lively look at fourteen champions of conservative thought—some well known, others hardly remembered at all. Taking readers on an exciting tour from the American Founding to the modern era, Tucker traces the development of conservatism’s basic tenets and shows how leaders put principle into action (some more successfully than others). Conservative Heroes offers brief but penetrating profiles of: —The Founders who agreed on the two primary purposes of government—but differed on how best to achieve the balance between them —The pair of nineteenth-century congressional leaders who fought to preserve the founding vision of a limited national government —The towering statesman whose defense of slavery has obscured his considerable contributions to American constitutional history —The last Democratic president to advance conservative principles —The president and treasury secretary who together reduced taxes and the size of the federal government—and sparked an economic boom —The forgotten leaders, both Democrats, who spearheaded the conservative challenge to FDR’s New Deal —The man who revived the GOP as the conservative party —The three driving forces behind the ascent of modern conservatism Here is the story of American conservatism in fourteen lives—a story we need to understand to tackle the challenges we face today.
