Book Description
Popular science at its most exciting: the breaking new world of chronobiology - understanding the rhythm of life in humans and all plants and animals. The entire natural world is full of rhythms. The early bird catches the worm -and migrates to an internal calendar. Dormice hibernate away the winter. Plants open and close their flowers at the same hour each day. Bees search out nectar-rich flowers day after day. There are cicadas that can breed for only two weeks every 17 years. And in humans: why are people who work anti-social shifts more illness prone and die younger? What is jet-lag and can anything help? Why do teenagers refuse to get up in the morning, and are the rest of us really 'larks' or 'owls'? Why are most people born (and die) between 3am-5am? And should patients be given medicines (and operations) at set times of day, because the body reacts so differently in the morning, evening and at night? The answers lie in our biological clocks the mechanisms which give order to all living things. They impose a structure that enables us to change our behaviour in relation to the time of day, month or year. They are reset at sunrise and sunset each day to link astronomical time with an organism's internal time.

Book Description
From one-celled paramecium to giant blue whales, we all have internal clocks that regulate the rhythms we live by. In The Living Clock, John Palmer, one of the world's leading authorities on these rhythms, takes us on a tour of this broad and multifaceted subject, examining everything from glowing fruit flies to the best cures for jet lag. Palmer has a wonderful sense of humor and an eye for the startling fact. We learn that fiddler crabs--in a lab where there are no time nor tide cues--remain active when low tide would occur and motionless during high tide, the same pattern they follow in their natural habitat. (In fact, you can remove a crab's leg and the leg will keep a tidal rhythm as long as it's kept alive.) Moreover, humans are subject to more than one hundred biological rhythms. Mental acuity peaks in the afternoon, for instance, and our blood pressure peaks at seven in the morning (when most heart attacks occur). The time of day you take medication can affect how well it works. And Palmer shows that when our clocks are thrown off kilter, trouble follows, especially for rotating shift workers--the Bhopal spill, the Chernobyl reactor explosion, and the Three Mile Island accident all happened when new crews began early-hour shifts. No one has discovered exactly how our internal clocks work--Palmer says a Nobel Prize awaits that lucky scientist--but they are no less fascinating for their inexplicable nature. Frequently amusing and always eye-opening, The Living Clock is a treat for everyone curious about the nature of life as well as anyone planning a long jet flight.

Book Description
A core principle of modern science holds that a scientific explanation must not attribute will or agency to natural phenomena. "The Restless Clock" examines the origins and history of this, in particular as it applies to the science of living things. This is also the story of a tradition of radicals--dissenters who embraced the opposite view, that agency is an essential and ineradicable part of nature. Beginning with the church and courtly automata of early modern Europe, Jessica Riskin guides us through our thinking about the extent to which animals might be understood as mere machines. We encounter fantastic robots and cyborgs as well as a cast of scientific and philosophical luminaries, including Descartes and Leibnitz, Lamarck and Darwin, whose ideas gain new relevance in Riskin's hands. The book ends with a riveting discussion of how the dialectic continues in genetics, epigenetics, and evolutionary biology, where work continues to naturalize different forms of agency. "The Restless Clock "reveals the deeply buried roots of current debates in artificial intelligence, cognitive science, and evolutionary biology.

Book Description
"Nickel and Dimed for the Amazon age," (Salon) the bitingly funny, eye-opening story of finding work in the automated and time-starved world of hourly low-wage labor After the local newspaper where she worked as a reporter closed, Emily Guendelsberger took a pre-Christmas job at an Amazon fulfillment center outside Louisville, Kentucky. There, the vending machines were stocked with painkillers, and the staff turnover was dizzying. In the new year, she travelled to North Carolina to work at a call center, a place where even bathroom breaks were timed to the second. And finally, Guendelsberger was hired at a San Francisco McDonald's, narrowly escaping revenge-seeking customers who pelted her with condiments. Across three jobs, and in three different parts of the country, Guendelsberger directly took part in the revolution changing the U.S. workplace. Offering an up-close portrait of America's actual "essential workers," On the Clock examines the broken social safety net as well as an economy that has purposely had all the slack drained out and converted to profit. Until robots pack boxes, resolve billing issues, and make fast food, human beings supervised by AI will continue to get the job done. Guendelsberger shows us how workers went from being the most expensive element of production to the cheapest - and how low wage jobs have been remade to serve the ideals of efficiency, at the cost of humanity. On the Clock explores the lengths that half of Americans will go to in order to make a living, offering not only a better understanding of the modern workplace, but also surprising solutions to make work more humane for millions of Americans.

Book Description
This is a book about time--about one's own journey through it and, more important, about enlarging the pleasure one takes in that journey. It's about memory of the past, hope and fear for the future, and how they color, for better and for worse, one's experience of the present. Ultimately, it's a book about freedom--freedom from despair of the clock, of the aging body, of the seeming waste of one's daily routine, the freedom that comes with acceptance and appreciation of the human dimensions of time and of the place of each passing moment on life's bounteous continuum. For Robert Grudin, living is an art, and cultivating a creative partnership with time is one of the keys to mastering it. In a series of wise, witty, and playful meditations, he suggests that happiness lies not in the effort to conquer time but rather in learning to bend to its curve, in hearing its music and learning to dance to it. Grudin offers practical advice and mental exercises designed to help the reader use time more effectively, but this is no ordinary self-help book. It is instead a kind of wisdom literature, a guide to life, a feast for the mind and for the spirit.

Book Description
"I well recall a conversation with an executive I hoped to interview about her astonishing productivity. I began our call with an assurance that I would not take much of her time. She laughed. 'Oh, I have all the time in the world,' she said." Most of us feel constantly behind, unsure how to escape feeling oppressed by busyness. Laura Vanderkam, unlike other time-management gurus, believes that in order to get more done, we must first feel like we have all the time in the world. Think about it: why haven't you trained for that 5K or read War and Peace? Probably because you feel beaten down by all the time you don't seem to have. In this book, Vanderkam reveals the seven counterintuitive principles the most time-free people have adopted. She teaches mindset shifts to help you feel calm on the busiest days and tools to help you get more done without feeling overwhelmed. You'll meet people such as... ♦ An elementary school principal who figured out how to spend more time mentoring teachers, and less time supervising the cafeteria ♦ An executive who builds lots of meeting-free space into his calendar, despite managing teams across multiple continents ♦ A CEO who does focused work in a Waffle House early in the morning, so he can keep an open door and a relaxed mindset all day ♦ An artist who overcame a creative block, and reached new heights of productivity, by being more gentle with herself, rather than more demanding The strategies in this book can help if your life feels out of control, but they can also help if you want to take your career, your relationships, and your personal happiness to the next level. Vanderkam has packed this book with insights from busy yet relaxed professionals, including "time makeovers" of people who are learning how to use these tools. Off the Clock can inspire the rest of us to create lives that are not only productive, but enjoyable in the moment.

Book Description
Anyone who has watched a wrinkle slowly gouge their face like a strip mine, or has been disturbed by a loss of memory, has uncomfortably confronted the human ageing process. The inexorable march of time on our bodies begs an important question: why do we have to grow old? Written in everyday language, The Clock of Ages takes us on a tour of the ageing human body - all from a research scientist's point of view. From the deliberate creation of organisms that live three times their natural span to the isolation of human genes that may allow us to do the same, The Clock of Ages also examines the latest discoveries in geriatric genetics. Sprinkled throughout the pages are descriptions of the aging of many historical figures, such as Florence Nightingale, Jane Austen, Bonaparte and Casanova. These stories underscore the common bond that unites us all: they aged, even as we do. The Clock of Ages tells you why.
