“America’s funniest technological know-how author” (Washington Post) takes us down the hatch on an unforgettable journey. The alimentary canal is vintage Mary Roach terrain: the questions explored in Gulp are as taboo, of their manner, because the cadavers in Stiff and each bit as surreal because the universe of 0 gravity explored in Packing for Mars. Why is crunchy nutrients so beautiful? Why is it so tough to discover phrases for flavors and scents? Why doesn’t the tummy digest itself? How a lot are you able to devour earlier than your belly bursts? Can constipation kill you? Did it kill Elvis? In Gulp we meet scientists who take on the questions not anyone else thinks of―or has the braveness to invite. We cross on situation to a pet-food taste-test lab, a fecal transplant, and right into a dwell belly to watch the destiny of a meal. With Roach at our aspect, we trip the realm, assembly murderers and mad scientists, Eskimos and exorcists (who have sometimes administered holy water rectally), rabbis and terrorists―who, it seems, for sensible purposes don't hide bombs of their digestive tracts.

Like all of Roach’s books, Gulp is as a lot approximately people because it is ready human bodies.

Download E-books Design in Nature: How the Constructal Law Governs Evolution in Biology, Physics, Technology, and Social Organizations PDF

By Adrian Bejan, J. Peder Zane

In this groundbreaking booklet, Adrian Bejan takes the habitual styles in nature—trees, tributaries, air passages, neural networks, and lightning bolts—and finds how a unmarried precept of physics, the constructal legislations, bills for the evolution of those and lots of different designs in our world.
 
Everything—from organic existence to inanimate systems—generates form and constitution and evolves in a chain of ever-improving designs with a purpose to facilitate move. River basins, cardiovascular platforms, and bolts of lightning are very effective move platforms to maneuver a current—of water, blood, or electrical energy. Likewise, the extra advanced structure of animals evolve to hide better distance in step with unit of worthwhile strength, or raise their circulate around the land. Such designs additionally look in human organisations, just like the hierarchical “flowcharts” or reporting buildings in businesses and political our bodies. All are ruled through a similar precept, often called the constructal legislations, and configure and reconfigure themselves over the years to move extra successfully. Written in a simple sort that achieves readability with out sacrificing complexity, Design in Nature is a paradigm-shifting booklet that would essentially rework our knowing of the realm round us.
