These novel and original dissections will be a gold mine for math puzzle enthusiasts and for math educators.

A dissection involves cutting a polygon into pieces in such a way that those pieces form another polygon; for a hinged dissection, the pieces must be attached by hinges. A piano hinge is "a long narrow hinge with a pin running the entire length of its joint." So, unlike regular hinged dissections, which swing or twist (around single point of hinge)

A comprehensive, beautifully illustrated survey accessible to anyone familiar with high school geometry.

This is a startling window into the education of American doctors in the late 19th and early 20th centuries-on both a visceral level and for its revealing cultural record. Cringe-worthy shots of medical students-bare-handed gentlemen and a few ladies in street clothes show off their scalpels, saws and textbooks-while their cadavers, mostly poor and black, are awkwardly posed, and exposed. In one stunning shot, a black woman looks out from behind the young students. "What are we to make of an African-American woman, standing, broom handle in hand, behind the dissection table, her gaze fixed on the camera?" the authors ask. More importantly, they conclude, the photo is now drawn "out of the shadows of history" where "we can at least bear witness." A blood-soaked dissection table makes you want to look away and the dark humor of students playing pranks with skeletons are both hilarious and horrible. Postcards sent to family and friends must have caused shock and awe for postmen and recipient alike. Here, a difficult glance into medicine's "uncomfortable past" offers a grand opportunity to understand the legacy doctors and patients live with, and benefit from, today.

Cardiovascular Pathology, Fourth Edition, provides users with a comprehensive overview that encompasses its examination, cardiac structure, both normal and physiologically altered, and a multitude of abnormalities. This updated edition offers current views on interventions, both medical and surgical, and the pathology related to them. Congenital heart disease and its pathobiology are covered in some depth, as are vasculitis and neoplasias. Each section has been revised to reflect new discoveries in clinical and molecular pathology, with new chapters updated and written with a practical approach, especially with regards to the discussion of pathophysiology. New chapters reflect recent technological advances with cardiac devices, transplants, genetics, and immunology. Each chapter is highly illustrated and covers contemporary aspects of the disease processes, including a section on the role of molecular diagnostics and cytogenetics as specifically related to cardiovascular pathology.

Until 1832, when an Act of Parliament began to regulate the use of bodies for anatomy in Britain, public dissection was regularlyand legallycarried out on the bodies of murderers, and a shortage of cadavers gave rise to the infamous murders committed by Burke and Hare to supply dissection subjects to Dr. Robert Knox, the anatomist. This book tells the scandalous story of how medical men obtained the corpses upon which they worked before the use of human remains was regulated. Helen MacDonald looks particularly at the activities of British surgeons in nineteenth-century Van Diemens Land, a penal colony in which a ready supply of bodies was available. Not only convicted murderers, but also Aborigines and the unfortunate poor who died in hospitals were routinely turned over to the surgeons. This sensitive but searing account shows how abuses happen even within the conventions adopted by civilized societies. It reveals how, from Burke and Hare to todays televised dissections by German anatomist Dr. Gunther von Hagens, some peoples bodies become other peoples entertainment.
