Paperback. Condición: Very Good. Reflections on the Motive Power of Fire, along with other papers in this volume, laid the foundation of modern thermodynamics. Highly readable, Reflections contains no arguments that depend on calculus, consisting mostly of statements couched in exact language. It represents a tribute to Carnot's capacity to generalize, and to see fundamental processes at work in complex mechanisms.Reflections on the Motive Power of Fire examines the relation between heat and the work done by heat in high- and low-pressure steam engines, air-engines, and an internal combustion machine. Carnot established conditions for the economical working of these engines and invented the closed cycle of operations. He realized that in any engine, the amount of work done by heat is determined solely by the range of temperature through which it fell in the operation. He extended the ideas of his father, Lazare Carnot, on mechanics to thermal processes, deriving statements on the impossibility of perpetual motion and the need to avoid irreversible changes.Little notice was paid to this book upon its 1824 publication; ten years later, Emile Clapeyron's more analytical paper on the same subject received wider attention. This English translation includes selections from Carnot's posthumous manuscripts and a paper by Rudolf Clausius that rewrote Carnot's results in a terminology that distinguished between change of entropy and quantity of heat.…

Hardback. Condición: Good. A heart-wrenching story of four students who find hope and kinship amidst the challenges of growing up at a harrowing Madrasa in rural Ontario Nabil, freshly plucked from middle school in Scarborough, is struggling to find his place at Al Haque Islamic Academy. Between the intense religious studies and new rules, he still longs for his past life of baseball, video games, comic books and girls. When he stumbles upon Maaz and Nawaaz doing something they shouldn't be doing, he quickly falls into their company and joins them in their misdeeds. And together with the new transfer student and unruly class clown Farid, the group executes their rebellion.   One day, while exploring the Madrasa at night, the boys discover the diary of a student who lived on the grounds when it was an all-girls Catholic school. Cynthia Lewis' words connect them to a bygone era and inspires them to hatch a plot to escape. They form a pact, and together, their ultimate decision sends them hurtling down a path that changes their lives forever.   Strikingly original, and as poignant as it is humorous, Land of No Regrets is a vibrant, compassionate exploration of faith, friendship, identity, and the true value of freedom.…
