Chemistry was not my forte in school, but he explains things so lucidly , while also mixing in interesting stories and humor, that he makes me want to pull up a chair to the periodical table. He goes through chapter by chapter all the gases present in our atmosphere and kind of explains why you should care, what they do and what you can learn from them. Of course there is stuff on flatulence, as well as volcanoes, the search for extra-terrestrial life and gas warfare. By the way, be sure to read the notes, there is always good stuff in kean's notes, sure to make you smile or laugh ( ) Sam Kean is a writer of books that discuss scientific discoveries in a relatable and entertaining style. Four of his books, The Violinist’s Thumb, The Disappearing Spoon, The Tale of The Dueling Neurosurgeons, and this one: Caesar’s Last Breath, were all named as Amazon's top science book of the year. Caesar’s Last Breath tackles the subject of the air we breathe; of gases more generally; and how their composition on earth tells the story of the evolution of the earth and of the ways in which mankind has changed its planet. Nitrogen and oxygen are the main ingredients of air, making up 99 per cent of what you inhale. If you ever wondered how small atoms (and in combination, molecules) actually are, Sam Kean includes a stunning set of statistics about the air we breathe. Every time you take a breath, you inhale nine sextillion molecules of nitrogen (78% of the air) and two sextillion molecules of oxygen (21% of air). But you inhale a lot of the remaining 1% of molecules as well; for example, whenever you breathe, you take in 120 billion molecules of sulfur dioxide and 60 billion molecules of hydrogen sulfide. Other gases you breathe include methane, ethanol, helium, argon, and more. That one per cent turns out to be pretty significant. It is responsible for all of global warming as well as all scents and perfumes. It includes gases released by volcanic eruptions, a number of pollutants from industrial development, and particles from nuclear bomb fallout. Kean’s exploration of the history of the air we breathe is peppered with interesting and eccentric characters. He begins with Harry Randall Truman, a stubborn man who refused to leave Mount Saint Helens in 1980 even after two months worth of warnings from the mountain itself. He tells what would have happened to him, as well as to the victims of the great eruption of Mt. Vesuvius, and how those volcanic gases altered the atmosphere. He profiles various chemists who studied gases, such as Antoine-Laurent Lavoisier - executed during the French Revolution - who once mummified a colleague to study breathing. He describes attempts to affect levels of rainfall, to predict the weather, and to take advantage of layers of air in the atmosphere for spying, this latter effort leading to “UFO” sightings around Roswell, New Mexico in the late 1940s. Evaluation: Kean is an excellent raconteur, and this collections of facts and anecdotes will have you itching to share them with everyone around you. I love Sam Kean and this pop science accounting of various atmospheric gases does not disappoint. Roughly arranged by contribution to Earth's atmosphere, the chapters bounce from hot air balloons to chemical warfare. Kean focuses on depth rather than breadth, making for memorable and engaging reading. sin reseñas | añadir una reseña

En El ltimo aliento de Csar, Sam Kean nos invita a emprender un viaje alrededor del mundo y a travs del tiempo para narrar la historia del aire que respiramos. Una historia que resulta ser la misma que la historia de la Tierra y de nuestra existencia en ella. En cada respiracin, literalmente estamos inhalando la historia del mundo. El 15 de marzo del ao 44 a. C, Julio Csar muri en el suelo del Senado tras haber sido apualado, pero la historia de su ltimo aliento todava se est desarrollando; de hecho, es probable que ahora mismo estemos inhalando parte de ese aire tan especial. De entre los sixtillones de molculas que entran o salen de tus pulmones en este momento, algunas podran contener trazas de los perfumes de Cleopatra, gas-mostaza del ejrcito nazi, partculas exhaladas por dinosaurios o emitidas por la bomba atmica, e incluso restos de nebulosa del origen del universo. Mientras investiga los orgenes y los ingredientes de nuestra atmsfera, Kean revela cmo la alquimia del aire model la forma de nuestros continentes, gui el progreso humano, aliment revoluciones, y contina siendo una gran influencia en todo aquello que hacemos.
