Book Description

"Our hearts have evolved to be extremely efficient, long-lasting pumps that exquisitely match the needs of our bodies. This book is about how the heart does this; how can a heart pump the blood for up to one hundred years while the best formula one racing engine has a working life measured in hours? Why is the heart so efficient, and how are worn out parts replaced while working? How does it generate the force to act as a pump, how is it controlled electrically, and how can it repair itself? This book addresses these questions from physiological and molecular perspectives in language that aims to be accessible to all interested in biology and with liberal illustrations. The story of how the heart works is presented in the context of its origins; How is the heart formed in the womb? How it evolved as an oxygen pump through many configurations following the onset of oxygenic photosynthesis 2.5 billion years ago? Why its intimate co-evolution with the circulation and blood was essential to enable its efficiency and longevity? The book begins with a discussion of why the word heart is universally used as a metaphor for reason and emotion and traces its origins in modern and ancient languages. The last chapter explains why most diseases of the heart can be attributed to a divergence between the lifestyle for which the heart is optimally evolved, and those lived today in high-income nations and increasingly in middle and lower-income nations. Advice on how to preserve the heart is presented in light of this"--

Book Description

A human-centric guide to solving complex problems in engineering management, from sizing teams to handling technical debt. There’s a saying that people don’t leave companies, they leave managers. Management is a key part of any organization, yet the discipline is often self-taught and unstructured. Getting to the good solutions for complex management challenges can make the difference between fulfillment and frustration for teams—and, ultimately, between the success and failure of companies. Will Larson’s An Elegant Puzzle focuses on the particular challenges of engineering management—from sizing teams to handling technical debt to performing succession planning—and provides a path to the good solutions. Drawing from his experience at Digg, Uber, and Stripe, Larson has developed a thoughtful approach to engineering management for leaders of all levels at companies of all sizes. An Elegant Puzzle balances structured principles and human-centric thinking to help any leader create more effective and rewarding organizations for engineers to thrive in.

Book Description

A page-turning novel that is also an exploration of the great philosophical concepts of Western thought, Jostein Gaarder's Sophie's World has fired the imagination of readers all over the world, with more than twenty million copies in print. One day fourteen-year-old Sophie Amundsen comes home from school to find in her mailbox two notes, with one question on each: "Who are you?" and "Where does the world come from?" From that irresistible beginning, Sophie becomes obsessed with questions that take her far beyond what she knows of her Norwegian village. Through those letters, she enrolls in a kind of correspondence course, covering Socrates to Sartre, with a mysterious philosopher, while receiving letters addressed to another girl. Who is Hilde? And why does her mail keep turning up? To unravel this riddle, Sophie must use the philosophy she is learning—but the truth turns out to be far more complicated than she could have imagined.
