This book and a telescope are all you need to find, view, and record your observations of the most popular stargazing targets. But what makes this list so famous? Over 200 years ago, the French comet hunter Charles Messier published a list of fuzzy, comet-like objects he saw through his telescope. To him, they were a nuisance. We now know them as star clusters, nebulae, and galaxies! Modern astronomers later expanded his list from 103 to 110 objects - and they're some of the finest celestial sights to explore with your backyard telescope, especially after you're ready to move beyond the Moon and planets. This book is your guide to seeing each deep sky object in Messier's list - plus a complete how-to for budding astronomers.
Finding the 110 Messier (pronounced Messy-ay) objects has never been easier! We provide a star map for each target - plus written directions for how to find it by star-hopping, an "eyepiece view" image to confirm you're seeing it, observing tips from two veteran stargazers, and interesting facts. We also highlight additional nearby objects.
These objects are presented in their recommended viewing order - either by season, or during an all-night marathon! Each page contains an observation log so you can track your progress, and later apply for a Messier Observing Certificate from the Astronomical League and the Royal Astronomical Society of Canada. Certificate Application instructions are provided in the appendix of the book.
What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There's no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson.
But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in tasty chapters consumable anytime and anywhere in your busy day.
While you wait for your morning coffee to brew, for the bus, the train, or a plane to arrive, Astrophysics for People in a Hurry will reveal just what you need to be fluent and ready for the next cosmic headlines: from the Big Bang to black holes, from quarks to quantum mechanics, and from the search for planets to the search for life in the universe.
Between the Lines is a book about tuning sound systems for live events, but more importantly, it's a book about making decisions. Beginning with an overview of system design fundamentals, the author then shares his personal approach to sound system design and alignment, and his rationale - not only why decisions are made, but also the order in which they are made, which can have a profound effect on the resulting uniformity of the system.
Readers will learn to consider the outcomes and tradeoffs throughout the process, and the author's school of thought yields a mental framework for creating consistency, regardless of the size, scope, or scale of the sound system.
From the cubit to the kilogram, the humble inch to the speed of light, measurement is a powerful tool that humans invented to make sense of the world. In this revelatory work of science and social history, James Vincent dives into its hidden world, taking readers from ancient Egypt, where measuring the annual depth of the Nile was an essential task, to the intellectual origins of the metric system in the French Revolution, and from the surprisingly animated rivalry between metric and imperial, to our current age of the "quantified self." At every turn, Vincent is keenly attuned to the political consequences of measurement, exploring how it has also been used as a tool for oppression and control.
Beyond Measure reveals how measurement is not only deeply entwined with our experience of the world, but also how its history encompasses and shapes the human quest for knowledge.
"You will marvel at the brilliance and vast weirdness of your design." --The Washington Post Bill Bryson once again proves himself to be an incomparable companion as he guides us through the human body--how it functions, its remarkable ability to heal itself, and (unfortunately) the ways it can fail. Full of extraordinary facts (your body made a million red blood cells since you started reading this) and irresistible Brysonesque anecdotes, The Body will lead you to a deeper understanding of the miracle that is life in general and you in particular. As Bill Bryson writes, "We pass our existence within this wobble of flesh and yet take it almost entirely for granted." The Body will cure that indifference with generous doses of wondrous, compulsively readable facts and information. As addictive as it is comprehensive, this is Bryson at his very best.
"A fascinating scientific, cultural, spiritual and evolutionary history of the way humans breathe--and how we've all been doing it wrong for a long, long time." --Elizabeth Gilbert, author of Big Magic and Eat Pray Love No matter what you eat, how much you exercise, how skinny or young or wise you are, none of it matters if you're not breathing properly. There is nothing more essential to our health and well-being than breathing: take air in, let it out, repeat twenty-five thousand times a day. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences. Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren't found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of São Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices like Pranayama, Sudarshan Kriya, and Tummo and teams up with pulmonary tinkerers to scientifically test long-held beliefs about how we breathe. Modern research is showing us that making even slight adjustments to the way we inhale and exhale can jump-start athletic performance; rejuvenate internal organs; halt snoring, asthma, and autoimmune disease; and even straighten scoliotic spines. None of this should be possible, and yet it is. Drawing on thousands of years of medical texts and recent cutting-edge studies in pulmonology, psychology, biochemistry, and human physiology, Breath turns the conventional wisdom of what we thought we knew about our most basic biological function on its head. You will never breathe the same again.
-Infectious disease experts saw this pandemic coming
-Some scientists, for more than two decades, warned that "the next big one" would be caused by a changeable new virus--very possibly a coronavirus--but such warnings were ignored for political or economic reasons
-The precise origins of this virus may not be known for years, but some clues are compelling, and some suppositions can be dismissed
-And much more Written by "one of our finest explainers of the natural world for decades" (Chicago Tribune), This "compelling and terrifying" (The New York Times) account is an unparalleled look inside the frantic international race to understand and control SARS-CoV-2--and what it might mean for the next potential global health crisis.
The classic guide to how computers work, updated with new chapters and interactive graphics
"For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think."
- Scott Hanselman, Partner Program Director, Microsoft, and host of Hanselminutes
Computers are everywhere, most obviously in our laptops and smartphones, but also our cars, televisions, microwave ovens, alarm clocks, robot vacuum cleaners, and other smart appliances. Have you ever wondered what goes on inside these devices to make our lives easier but occasionally more infuriating?
For more than 20 years, readers have delighted in Charles Petzold's illuminating story of the secret inner life of computers, and now he has revised it for this new age of computing. Cleverly illustrated and easy to understand, this is the book that cracks the mystery. You'll discover what flashlights, black cats, seesaws, and the ride of Paul Revere can teach you about computing, and how human ingenuity and our compulsion to communicate have shaped every electronic device we use.
This new expanded edition explores more deeply the bit-by-bit and gate-by-gate construction of the heart of every smart device, the central processing unit that combines the simplest of basic operations to perform the most complex of feats. Petzold's companion website, CodeHiddenLanguage.com, uses animated graphics of key circuits in the book to make computers even easier to comprehend.
In addition to substantially revised and updated content, new chapters include:
From the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution.
A lot of Engineering Managers and leaders studied for years and years to become the best Engineer they possibly could be... and then they were promoted.
It can be very tough for those of us who didn't go into Engineering with the distinct concept that we would become managers, but still want to do our best to support our teams.
I wrote this book because there's so much no one told me about management that I wished I would have known. There's a lot to be purposeful about that many of us learn on the job, and worse: learn on people. This book provides some organization for collaborating with networks of people, working together towards a common purpose.
There seem to be millions of articles and "how to"s on programming and only a handful of resources on Engineering Management- why? It's very tough to talk about something that involves people processes. People are non-deterministic. Working relationships are nuanced, communication is linked with individual values, motivations, power dynamics, and skills. People also have a range of experiences and emotions that are not consistent day-to-day.
Hopefully, in the happiest, most productive sense.
It's imperative that we as managers learn as much as we can and work on ourselves, so that our teams may enjoy a healthy working life and strong relationships. It's not just important, it's crucial that we iterate on our own skills as managers so that we can properly support everyone around us: individuals, peers, leadership, and the business.
I'm sharing what I've learned- not so that you follow my concepts exactly, but rather so that you can be thoughtful about your own leadership and needs. The book goes from the macro to the micro- with topics ranging everywhere from "feedback" to "scoping down PRs".
Though the book is meant to address people in management, individual contributors are welcome to read the book as well- perhaps you need to manage up and need some tools to help guide the conversation, perhaps you just want a peek at other concerns within the business- everyone is invited to the conversation.
