The invention of numerals is likely to be the best abstraction the human brain has ever created. nearly every thing in our lives is electronic, numerical, or quantified. the tale of the way and the place we acquired those numerals, which we so rely on, has for hundreds of thousands of years been shrouded in secret. Finding Zero is an event stuffed saga of Amir Aczel's lifelong obsession: to discover the unique assets of our numerals. Aczel has doggedly crisscrossed the traditional international, scouring dusty, moldy texts, go studying so-called students who provided wildly differing units of evidence, and eventually penetrating deep right into a Cambodian jungle to discover a definitive evidence. right here, he's taking the reader alongside for the ride.
The heritage starts off with the early Babylonian cuneiform numbers, by way of the later Greek and Roman letter numerals. Then Aczel asks the main query: the place do the numbers we use this present day, the so-called Hindu-Arabic numerals, come from? it's this seek that leads him to discover uncharted territory, to move on a grand quest into India, Thailand, Laos, Vietnam, and finally into the wilds of Cambodia. There he's blown away to discover the earliest zero—the keystone of our whole approach of numbers—on a crumbling, vine-covered wall of a seventh-century temple embellished with eaten-away erotic sculptures. whereas in this odyssey, Aczel meets a bunch of attention-grabbing characters: teachers looking for fact, jungle trekkers trying to find experience, strangely sincere politicians, shameless smugglers, and treacherous archaeological thieves—who eventually show the place our numbers come from.

New PDF release: The Panic Virus: A True Story of Medicine, Science, and Fear
WHO makes a decision WHICH proof ARE real?
In 1998 Andrew Wakefield, a British gastroenterologist with a historical past of self-promotion, released a paper with a surprising allegation: the measles-mumps-rubella vaccine could reason autism. The media seized carry of the tale and, within the procedure, helped to release some of the most devastating wellbeing and fitness scares ever. within the years yet to come Wakefield will be printed as a profiteer in league with class-action legal professionals, and he could ultimately lose his clinical license. in the meantime one learn after one other didn't locate any hyperlink among formative years vaccines and autism.
Yet the parable that vaccines by some means reason developmental issues lives on. regardless of the inability of corroborating facts, it's been popularized by way of media personalities corresponding to Oprah Winfrey and Jenny McCarthy and legitimized by way of newshounds who declare that they're simply being reasonable to “both sides” of a topic approximately which there's little debate. in the meantime hundreds of thousands of bucks were diverted from power breakthroughs in autism study, households have spent their discounts on useless “miracle cures,” and declining vaccination charges have ended in outbreaks of lethal health problems like Hib, measles, and whooping cough. such a lot tragic of all is the expanding variety of young ones loss of life from vaccine-preventable ailments.
In The Panic Virus Seth Mnookin attracts on interviews with mom and dad, public-health advocates, scientists, and anti-vaccine activists to take on a primary query: How can we come to a decision what in actual fact? The attention-grabbing resolution is helping clarify every thing from the endurance of conspiracy theories approximately Sep 11 to the charm of talk-show hosts who call for that President Obama “prove” he was once born in the USA.
The Panic Virus is a riveting and infrequently heart-breaking clinical detective tale that explores the bounds of rational inspiration. it's the final cautionary story for our time.

Fig. , 2006b) displays the comparison of cyclability among the pristine NG spheres, the NG with CNF as direct fillers, and the NG/CNF in situ composite. It is clearly seen that a great improvement in cycling performance is achieved for the in situ composite, the capacity of which is still kept at above 300 mAh/g up to 45 cycles, about 150 mAh/g higher than that of the pristine NG. On the contrary, the capacity of the pristine NG and the NG with CNF as fillers drops continuously in the whole cycles.
