History has іt thаt cogs were fіrѕt uѕеd bу Grееkѕ іn clocks аnd water whееlѕ аrоund 3rd сеnturу B.C. Hоwеvеr, a сlеаr оrіgіn оf thеѕе simple mасhіnеѕ саn bе trасеd back to a vеhісlе thаt wаѕ аllеgеdlу engineered by Mа Jun, a Chіnеѕе mechanical engineer, іn thе 27th century B.C. Thе сhаrіоt was buіlt on two whееlѕ, аnd it bore a mоvаblе іndісаtоr thаt wаѕ mесhаnісаllу geared to fасе tоwаrdѕ Sоuth оnlу, nо mаttеr hоw much the vehicle turnеd.

Thе origin оf gears gоеѕ dоwn tо thе Chinese Sоuth-Pоіntіng Chariot іn thе 27th Cеnturу B.C. This сhаrіоt was knоwn to роіntіng tо thе ѕоuth nо matter how іt was turnеd. Arіѕtоtlе hаѕ thе сrеdіt tо hіѕ name of gіvіng thе earliest dеѕсrірtіоn of gears іn the 4th сеnturу B.C. Aссоrdіng tо his dеfіnіtіоn, thе dіrесtіоn оf rotation is rеvеrѕеd whеn оnе еаr wheel drіvеѕ аnоthеr gеаr wheel. Gеаrѕ hаvе bееn uѕеd by thе Greek Inventors in wаtеr wheels аnd clocks.

From Recognition to Reconciliation: Essays on the Constitutional Entrenchment of Aboriginal and Treaty Rights By Patrick Macklem (editor), Douglas Sanderson (editor) 2016 | 536 Pages | ISBN: 1442637293 | PDF | 2 MB More than thirty years ago, section 35 of the Constitution Act recognized and affirmed "the existing aboriginal and treaty rights of the aboriginal peoples of Canada." Hailed at the time as a watershed moment in the legal and political relationship between Indigenous peoples and settler societies in Canada, the constitutional entrenchment of Aboriginal and treaty rights has proven to be only the beginning of the long and complicated process of giving meaning to that constitutional recognition.In From Recognition to Reconciliation, twenty leading scholars reflect on the continuing transformation of the constitutional relationship between Indigenous peoples and the Canadian state. The book features essays on themes such as the role of sovereignty in constitutional jurisprudence, the diversity of methodologies at play in these legal and political questions, and connections between the Canadian constitutional experience and developments elsewhere in the world.

Parolek, Karen Parolek, Paul C. Crawford 2008 | 352 Pages | ISBN: 0470049855 | PDF | 52 MB A comprehensive, illustrative guide to Form-Based Codes "This volume describes in clear argument and significant detail the issues and techniques associated with the design and management of Form-Based Codes as an antidote to zoning and sprawl. Reading it and putting it to practice is an excellent point of departure for individuals and municipalities to safeguard and to grow their communities." - From the Foreword by noted architect and urbanist Stefanos Polyzoides Form-Based Codes are the latest evolutionary step in the practice of development and land-use regulation. A growing alternative to conventional zoning laws, Form-Based Codes go beyond land use to address not just the physical form of buildings but also surrounding streets, blocks, and public spaces in order to create, protect, and revitalize sustainable communities. Written by three recognized leaders in the field of New Urbanism, including an urban planner and an architect, this book is the first to address this subject comprehensively. After defining Form-Based Codes and explaining why they are a necessary alternative to conventional zoning regulations, the authors detail the various components of Form-Based Codes and then go step by step through the process of creating and implementing them. Finally, a series of case studies illustrates best practice applications of Form-Based Coding at various scales from county-wide to site specific, and various project types from city-wide development code replacement to the preservation or evolution of downtowns. This timely and accessible text features: * More than 200 clear illustrations of Form-Based Codes * Studies of real-world applications of Form-Based Coding by leading planners, urban designers, and architects Form-Based Codes is a must-read for today's urban designers, urban planners, architects, and anyone with a vested interest in utilizing the latest regulatory tool to help create compact, walkable, and sustainable communities.

Force of Imagination: The Sense of the Elemental By John Sallis 2000 | 256 Pages | ISBN: 0253337720 | PDF | 27 MB Force of ImaginationThe Sense of the ElementalJohn SallisA bold and original investigation into how imagination shapes thought and feeling."This is a bold new direction for the author, one that he takes in an arresting and convincing manner.... a powerful, original approach to what others call 'ecology' but what Sallis shows to be a question of the status of the earth in philosophical thinking at this historical moment." -Edward S. CaseyIn this major original work, John Sallis probes the very nature of imagination and reveals how the force of imagination extends into all spheres of human life. While drawing critically on the entire history of philosophy, Sallis's work takes up a vantage point determined by the contemporary deconstruction of the classical opposition between sensible and intelligible. Thus, in reinterrogating the nature of imagination, Force of Imagination carries out a radical turn to the sensible and to the elemental in nature. Liberated from subjectivity, imagination is shown to play a decisive role both in drawing together the moments of our experience of sensible things and in opening experience to the encompassing light, atmosphere, earth, and sky. Set within this elemental expanse, the human sense of time, of self, and of the other proves to be inextricably linked to imagination and to nature. By showing how imagination is formative for the very opening upon things and elements, this work points to the revealing power of poetic imagination and casts a new light on the nature of art.John Sallis is Liberal Arts Professor of Philosophy at Pennsylvania State University. His previous books include Being and Logos: Reading the Platonic Dialogues; Shades-Of Painting at the Limit; Stone; Chorology: On Beginning in Plato's Timaeus (all published by Indiana University Press), Crossings: Nietzsche and the Space of Tragedy and Double Truth.Studies in Continental Thought-John Sallis, editorContentsProlusionsOn (Not Simply) BeginningRemembranceDuplicity of the ImageSpacing the ImageTractive ImaginationThe ElementalTemporalitiesProprietiesPoetic Imagination |
