<p>Why Machines Learn</p>

<p>'An invaluable companion for anyone who wants a deep understanding of what’s under the hood of often inscrutable machines' Melanie Mitchell</p>

<p>A rich, narrative explanation of the mathematics that has brought us machine learning and the ongoing explosion of artificial intelligence</p>

<p>Machine-learning systems are making life-altering decisions for us: approving mortgage loans, determining whether a tumour is cancerous, or deciding whether someone gets bail. They now influence discoveries in chemistry, biology and physics - the study of genomes, extra-solar planets, even the intricacies of quantum systems.</p>

<p>We are living through a revolution in artificial intelligence that is not slowing down. This major shift is based on simple mathematics, some of which goes back centuries: linear algebra and calculus, the stuff of eighteenth-century mathematics. Indeed by the mid-1850s, a lot of the groundwork was all done. It took the development of computer science and the kindling of 1990s computer chips designed for video games to ignite the explosion of AI that we see all around us today. In this enlightening book, Anil Ananthaswamy explains the fundamental maths behind AI, which suggests that the basics of natural and artificial intelligence might follow the same mathematical rules.</p>

<p>As Ananthaswamy resonantly concludes, to make the most of our most wondrous technologies we need to understand their profound limitations - the clues lie in the maths that makes AI possible.</p>

<p>The Anxious Generation</p>

<p>From New York Times bestselling co-author of The Coddling of the American Mind, an essential investigation into the collapse in youth mental health—and a scientifically proven path to health and strengthThere is no bigger public health story now than the collapse in youth mental health. The numbers are terrifying and dominate our headlines. There has been much debate over how we got here, and what to do next, and bestselling author and social psychologist Jonathan Haidt is at the white-hot center of that discourse. Haidt has spent his career speaking wisdom and truth into the most difficult landscapes—communities polarized by politics and religion, campuses battling culture wars, and now the perfect storm contributing to a public health emergency for Gen Z.For the cohort that hit puberty around 2009, their sense of self developed as the threads of three dramatic technological and social changes smartphones and life with the constant companionship of a screen, front-facing cameras and the bevy of apps that thrived on selfie-culture, and social networks that reduced engagement and affirmation to likes and hearts alone. But phones aren’t the only villain here; the ground for this crisis was seeded by a decades long shift from play-based childhoods to ones defined by over-supervision, structure, and fear.The Anxious Generation is a penetrating and alarming accounting of how we adults began to overprotect children in the real world while giving essentially no protection in the brutal online world. Haidt documents the four fundamental harms of the phone-based sleep deprivation, social deprivation, cognitive fragmentation, and addiction. He then shows the unique harms affecting boys, and the unique harms affecting girls. In the last section of The Anxious Generation , he offers concrete and scientifically based advice with separate chapters addressed to parents, schools, universities, governments, and to teens themselves. He draws on ancient wisdom and modern psychology to help everyone understand what healthy development would look like in the digital age.</p>

<p>Bullshit Jobs</p>

<p>Huge swathes of people spend their days performing tasks they secretly believe are not really necessary. This book shows why, and what we can do about it</p>

<p>Back in 1930, the economist John Maynard Keynes prophesied that by the century's end, technology would see us all working fifteen-hour weeks. But instead, something curious happened. Today, average working hours have not decreased, but increased. And now, across the developed world, three-quarters of all jobs are in services or admin, jobs that don't seem to add anything to society: bullshit jobs. In Bullshit Jobs, David Graeber explores how this phenomenon - one more associated with the 20th-century Soviet Union, but which capitalism was supposed to eliminate - has happened. In doing so, he looks at how we value work, and how, rather than being productive, work has become an end in itself; the way such work maintains the current broken system of finance capital; and, finally, how we can get out of it.</p>

<p>Love Triangle: The Life-Changing Magic Of Trigonometry</p>

<p>A 1 SUNDAY TIMES BESTSELLER</p>

<p>Explore the life-changing magic of trigonometry with Matt Parker, stand-up mathematician and No. 1 bestselling author of Humble Pi</p>

<p>Why can no two people ever see the same rainbow? What happens when you pull a pop song apart into pure sine waves and play it back on a piano? Why does the wake behind a duck always form an angle of exactly 39 degrees? And what did mathematicians have to do with the great pig stampede of 2012? The answer to each of these questions can be found in the triangle.</p>

<p>In Love Triangle, stand-up comedian, ex-maths teacher and Sunday Times number one bestselling author Matt Parker is on a mission to prove why we should all show a lot more love for triangles, along with the useful trigonometry and geometry they enable. To make his point, he uses triangles to create his own digital avatar, survive a harrowing motorcycle ride, cut a sandwich into three equal parts, and measure tall buildings while wearing silly shoes. But soon these hare-brained experiments begin to reveal a genuinely important truth: triangles are the hidden pattern beneath the surface of the contemporary world, used in everything from GPS to CGI via Spotify streaming, the play button and your best mate’s triangle tattoo.</p>

<p>Join Matt Parker as he demonstrates why there’s more to triangles than Pythagoras and SOHCAHTOA. Triangles are everything and everything is triangles.</p>
