 Tilings of the Plane: From Escher via Möbius to Penrose English | 2022 | ISBN: 3658388099 | 284 Pages | PDF (True) | 28 MB The aim of the book is to study symmetries and tesselation, which have long interested artists and mathematicians. Famous examples are the works created by the Arabs in the Alhambra and the paintings of the Dutch painter Maurits Escher. Mathematicians did not take up the subject intensively until the 19th century. In the process, the visualisation of mathematical relationships leads to very appealing images. Three approaches are described in this book.  Tiya Miles, "Ties That Bind: The Story of an Afro-Cherokee Family in Slavery and Freedom" English | 2015 | ISBN: 0520285638 | PDF | pages: 417 | 5.5 mb This beautifully written book, now in its second edition, tells the haunting saga of a quintessentially American family. In the late 1790s, Shoe Boots, a famed Cherokee warrior and successful farmer, acquired an African slave named Doll. Over the next thirty years, Shoe Boots and Doll lived together as master and slave and also as lifelong partners who, with their children and grandchildren, experienced key events in American history―including slavery, the Creek War, the founding of the Cherokee Nation and subsequent removal of Native Americans along the Trail of Tears, and the Civil War. This is the gripping story of their lives, in slavery and in freedom.

 David H. Price, "Threatening Anthropology: McCarthyism and the FBI's Surveillance of Activist Anthropologists" English | 2004 | ISBN: 0822333384 | PDF | pages: 435 | 3.3 mb A vital reminder of the importance of academic freedom, Threatening Anthropology offers a meticulously detailed account of how U.S. Cold War surveillance damaged the field of anthropology. David H. Price reveals how dozens of activist anthropologists were publicly and privately persecuted during the Red Scares of the 1940s and 1950s. He shows that it was not Communist Party membership or Marxist beliefs that attracted the most intense scrutiny from the fbi and congressional committees but rather social activism, particularly for racial justice. Demonstrating that the fbi's focus on anthropologists lessened as activist work and Marxist analysis in the field tapered off, Price argues that the impact of McCarthyism on anthropology extended far beyond the lives of those who lost their jobs. Its messages of fear and censorship had a pervasive chilling effect on anthropological investigation. As critiques that might attract government attention were abandoned, scholarship was curtailed.  Thinking in the Ruins: Wittgenstein and Santayana on Contingency By Michael P. Hodges, John Lachs 2000 | 144 Pages | ISBN: 0826513417 | PDF | 7 MB While Ludwig Wittgenstein (1889-1951) and George Santayana (1863-1952) may never have met or even have studied one another's work, they experienced similar cultural conditions and their thinking took similar shapes. Yet, until now, their respective bodies of work have been examined separately and in isolation from one another. Santayana is often regarded as an aesthetician and metaphysician, but Wittgenstein's work is usually seen as antithetical to the philosophical approaches favored by Santayana. In this insightful new study, Michael Hodges and John Lachs argue that behind the striking differences in philosophical style and vocabulary there is a surprising agreement in position. The similarities have largely gone unnoticed because of their divergent styles, different metaphilosophies, and separate spheres of influence. Hodges and Lachs show that Santayana's and Wittgenstein's works express their philosophical responses to contingency. Surprisingly, both thinkers turn to the integrity of human practices to establish a viable philosophical understanding of the human condition. Both of these important twentieth-century philosophers formed their mature views at a time when the comfortable certainties of Western civilization were crumbling all around them. What they say is similar at least in part because they wished to resist the spread of ruin by relying on the calm sanity of our linguistic and other practices. According to both, it is not living human knowledge but a mistaken philosophical tradition that demands foundations and thus creates intellectual homelessness and displacement. Both thought that, to get our house in order, we have to rethink our social, religious, philosophical, and moral practices outside the context of the search for certainty. This insight and the projects that flowed from it define their philosophical kinship. Thinking in the Ruins will enhance our understanding of these monumental thinkers' intellectual accomplishments and show how each influenced subsequent American philosophers. The book also serves as a call to philosophers to look beyond traditional classifications to the substance of philosophical thought.  The way to the top: The basics of success by Gabriel Grayson English | 2022 | ISBN: N/A | ASIN: B0BHBVT3T9 | 315 pages | EPUB | 0.56 Mb Discipline is an important thing to create excellence in a person in accomplishing work, which is the ability to make the soul submit to doing a certain thing, whether it wants to do it or not.

What followed would ignite a Southwestern frontier war between the Chiricahuas and the US Army that would last twenty-five years. In the days following the initial melee, innocent passersby would be taken as hostages on both sides, and almost all of them would be brutally slaughtered. Thousands of lives would be lost, the economies of Arizona and New Mexico would be devastated, and in the end, the Chiricahua way of life would essentially cease to exist.
