「勝手気まま」に生きるのが、健康寿命を延ばすコツ！60代・70代・80代・90代の心身の変化と過ごし方を、「老い方」の見取り図で分かりやすく解説。

The US healthcare system excels in research, innovation, and clinical care, but is failing to keep up with the operational challenges of the digital age. Today’s healthcare organizations face immense financial challenges, and their most valuable resources - people, rooms, and equipment - are being used inefficiently. The result? Long wait times for patients, overstressed staff, underused assets, and poor ROI for organizations.

The beauty of fractal patterns and their relation to chaos, as well as the history of chaos, and its uses in the real world and implications for the philosophy of science are all discussed in this Very Short Introduction audiobook.

Eva Walker is a 17-year-old math genius. And if that doesn't do wonders for her popularity, there's another thing that makes it even worse: When she touches another person or anything that belongs to them - from clothes to textbooks to cell phones - she sees a vision of their emotions. She can read a person's fears and anxieties, their secrets and loves...and what they have yet to learn about calculus. This is helpful for her work as a math tutor, but it means she can never get close to people. Eva avoids touching anyone and everyone.

Are the secrets of the universe written in words - or is it all about the digits? K. C. Cole follows up her paean to the power of physics, Sympathetic Vibrations, with this engaging and accessible guide to the might and majesty of mathematics. The Universe and the Teacup uses relatable examples and humorous prose to demonstrate math's ability to "translate the complexity of the world into manageable patterns".

Math-genius mercenary Cas Russell has stopped a shadow organization from brainwashing the world and discovered her past was deliberately erased and her superhuman abilities deliberately created. And that's just the start: When a demolitions expert targets Cas and her friends, and the hidden conspiracy behind Cas' past starts to reappear, the past, present, and future collide in a race to save one of her dearest friends.

Fourteen-year-old Nephele used to have friends. Well, she had a friend. That friend made the adjustment to high school easily, leaving Nephele behind in the process. And as Nephele looks ahead, all she can see is three very lonely years. Nephele is also a whip-smart lover of math and science, so she makes a plan. Step one: invent time travel. Step two: go back in time, have a do-over of ninth grade, crack the code on making friends, and become beloved and popular. Does it work? Sort of. Nephele does travel through time, but not the way she planned - she’s created a time loop.

Nous vivons dans un monde rempli de préjugés. Et cela ne doit rien au hasard. Notre cerveau, fabuleuse machine à appréhender le monde, fabrique sans cesse des stéréotypes et fait de nous, que nous le voulions ou non, de parfaits discriminateurs. Mais, ne vous en faites pas car nous allons vous expliquer pourquoi ce processus est parfaitement normal et comment en limiter les effets néfastes.

American democracy is at risk. Fueled by partisan news and emotion-stoking social media, Americans are becoming less and less able to think rationally about the challenges facing the country. For self-governance to succeed, citizens must analyze issues objectively, engage with one another respectfully, and ground their disagreements in reason and facts. At this precarious moment in our history, we need a renaissance in critical thinking. It can start in the math classroom.

An inhumane math pervades this country: even as our government extracts labor and often taxes from undocumented workers, it excludes these same workers from its social safety net. As a result, these essential workers struggle to get their own basic needs met, from healthcare to education, from freedom of association to the ability to drive to work without looking for ICE in the rearview mirror. An undocumented activist and a social scientist come together to tally of the structural costs of undocumented life.

The Cold War seemingly ended in a decisive victory for the West. But now, Noah Feldman argues, we are entering an era of renewed global struggle: the era of Cool War. Just as the Cold War matched the planet’s reigning superpowers in a contest for geopolitical supremacy, so this new age will pit the United States against a rising China in a contest for dominance, alliances, and resources. Already visible in Asia, the conflict will extend to the Middle East (U.S.-backed Israel versus Chinese-backed Iran), Africa, and beyond.

From medieval robots and Boolean algebra to facial recognition, artificial neural networks, and adversarial patches, this fascinating history takes listeners on a vast tour through the world of artificial intelligence. Award-winning author Clifford A. Pickover explores the historic and current applications of AI in such diverse fields as computing, medicine, popular culture, mythology, and philosophy, and considers the enduring threat to humanity should AI grow out of control.

The ACT is a standardized test designed to show colleges how prepared you are for higher education by measuring your reading comprehension, knowledge of writing conventions, and computational skills and then comparing you with the rest of the high schoolers who take it. This ACT prep audio program is designed for busy students like YOU who want step-by-step and affordable guidance for this entrance exam.

In Fluke, mathematician Joseph Mazur takes a second look at the seemingly improbable, sharing with us an entertaining guide to the most surprising moments in our lives. He takes us on a tour of the mathematical concepts of probability, such as the law of large numbers and the birthday paradox, and combines these concepts with lively anecdotes of flukes from around the world. How do you explain finding your college copy of Moby Dick in a used bookstore on the Seine on your first visit to Paris?
