Download or read book Light and Color in the Outdoors written by Marcel Minnaert and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: All of science springs from the observation of nature. In this classic book, the late Professor Minnaert accompanies the reader on a tour of nature's light and color and reveals the myriad phenomena that may be observed outdoors with no more than a pair of eyes and an enquiring mind. From the intriguing shape of the dapples beneath a tree on a sunny day, via rainbows, mirages, and haloes, the colors of liquid, ice, and the sky, to the appearance of the sun, moon, planets, and stars - Minnaert describes and explains them all in a clear language accessible to laymen. This new English edition is supplemented by 80 plates, over half of them in color, taken by the acclaimed photographer Pekka Parviainen, illustrating many of the phenomena - ordinary and exotic - discussed in the book.

This book was released on 2013-04-17 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dark Matter, Dark Energy and Dark Gravity make life possible!This book for the lay reader provides a summary of the latest astrophysical observational results and theoretical insights into what we know and what we hope to learn about dark matter, dark energy, and dark gravity.How did the profound beauty of our Earth, our Solar System, our Milky Way galaxy and indeed our universe unfold? Dark matter, dark energy, and dark gravity have made all the difference in how the universe has developed, and have been key to creating the overall environment that makes life possible. We have only recently developed the ability to begin unlocking their secrets, thus providing a deeper insight into how a universe of our type is possible. It seems that because of dark matter, dark energy and dark (weak) gravity, our universe has the right attributes for the development of complex structure and the evolution of intelligent life that can engage in the quest to understand our world. These "dark" or more hidden attributes of the cosmos have very good outcomes.In particular, the existence of dark matter makes it easier to form complex structures, including galaxies, stars and planets through gravitational collapse of denser regions of the universe. Planets are the most suitable abodes for the development of life. Dark energy acts to extend the lifetime of the universe by counteracting gravity and driving continued expansion of the universe.Even as far back as the 1930s there has been evidence that most of the matter in the universe was not visible via electromagnetic radiation (optical light, radio waves, etc.). By the last few decades of the 20th century, the case for a considerable amount of this dark matter was very strong. It is the second largest contributor to the total mass-energy of the universe. We don't know what it is and there are various candidates to explain it; nevertheless we see the gravitational effects of dark matter everywhere on the largest scales. Recent observational results indicate that dark matter dominates by a factor of 6 relative to the ordinary matter that makes up stars, planets, and living things.We now know that the major contributor to the mass-energy of the universe is not the substantial dark matter, but the 'newer' so-called dark energy. Dark energy acts to some extent as a negative gravity, and for the last several billion years has driven the expansion of the universe to a faster and faster pace, overcoming even the gravitational effect of dark matter. We have a general idea that it is the irreducible energy found in every volume of space, even in the absence of matter - in the vacuum. We don't understand why it takes the value that it does, one that is small in quantum particle physics terms, but nevertheless is of great significance on the large cosmological scale of the universe. The third important aspect to consider is not a mass-energy component, but the nature of gravity and space-time. The big question here is - why is gravity so relatively weak, as compared to the other 3 forces of nature? These 3 forces are the electromagnetic force, the strong nuclear force, and the weak nuclear force. Gravity is different - it has a dark or hidden side. It may very well operate in extra dimensions beyond the normal 4 dimensions of space-time that we can observe. This is what we mean in this book by "dark gravity".

Book excerpt: A WALL STREET JOURNAL BESTSELLER! "You can't really know anything if you just remember isolated facts. If the facts don't hang together on a latticework of theory, you don't have them in a usable form. You've got to have models in your head." - Charlie Munger, investor, vice chairman of Berkshire Hathaway The world's greatest problem-solvers, forecasters, and decision-makers all rely on a set of frameworks and shortcuts that help them cut through complexity and separate good ideas from bad ones. They're called mental models, and you can find them in dense textbooks on psychology, physics, economics, and more. Or, you can just read Super Thinking, a fun, illustrated guide to every mental model you could possibly need. How can mental models help you? Well, here are just a few examples... • If you've ever been overwhelmed by a to-do list that's grown too long, maybe you need the Eisenhower Decision Matrix to help you prioritize. • Use the 5 Whys model to better understand people's motivations or get to the root cause of a problem. • Before concluding that your colleague who messes up your projects is out to sabotage you, consider Hanlon's Razor for an alternative explanation. • Ever sat through a bad movie just because you paid a lot for the ticket? You might be falling prey to Sunk Cost Fallacy. • Set up Forcing Functions, like standing meeting or deadlines, to help grease the wheels for changes you want to occur. So, the next time you find yourself faced with a difficult decision or just trying to understand a complex situation, let Super Thinking upgrade your brain with mental models.

Download or read book A Sideways Look at Clouds written by Maria Mudd Ruth and published by Mountaineers Books. This book was released on 2017-08-18 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: • Written by a critically-acclaimed natural-history author • Shares author’s fun journey to understanding clouds • Written for the curious—but non-science—minded Author Maria Mudd Ruth fell in love with clouds the same way she stumbles into most passions: madly and unexpectedly. A Sideways Look at Clouds is the story of her quite accidental infatuation with and education about the clouds above. When she moved to the soggy Northwest a decade ago, Maria assumed that locals would know everything there was to know about clouds, in the same way they talk about salmon, tides, and the Seahawks. Yet in her first two years of living in Olympia, Washington, she never heard anyone talk about clouds—only the rain. Puzzled by this lack of cloud savvy, she decided to create a 10-question online survey and sent it to everyone she knew. Her sample size of 67 people included men and women, new friends in Olympia, family on the East Coast, outdoorsy and indoorsy types, professional scientists, and liberal arts majors like herself. The results showed that while people knew a little bit about clouds, most were like her—they had a hard time identifying clouds or remembering their names. As adults, they had lost their curiosity and sense of wonder about clouds and were, essentially, not in the habit of looking up. A Sideways Look at Clouds acknowledges the challenges of understanding clouds and so uses a very steep and bumpy learning curve—the author’s—as its plot line. The book is structured around the ten words used in most definitions of a cloud: “a visible mass of water droplets or ice crystals suspended in the atmosphere above the earth.” A captivating story teller, Maria blends science, wonder, and humor to take the scenic route through the clouds and encourages readers to chart their own rambling, idiosyncratic course.

Book excerpt: NAMED ONE OF THE BEST BOOKS OF THE YEAR BY People ∙ O: The Oprah Magazine ∙ Financial Times ∙ Kansas City Star ∙ BookPage ∙ Kirkus Reviews ∙ Publishers Weekly ∙ Booklist NEW YORK TIMES BESTSELLER “A stunner.”—Justin Cronin “It’s never the disasters you see coming that finally come to pass—it’s the ones you don’t expect at all,” says Julia, in this spellbinding novel of catastrophe and survival by a superb new writer. Luminous, suspenseful, unforgettable, The Age of Miracles tells the haunting and beautiful story of Julia and her family as they struggle to live in a time of extraordinary change. On an ordinary Saturday in a California suburb, Julia awakes to discover that something has happened to the rotation of the earth. The days and nights are growing longer and longer; gravity is affected; the birds, the tides, human behavior, and cosmic rhythms are thrown into disarray. In a world that seems filled with danger and loss, Julia also must face surprising developments in herself, and in her personal world—divisions widening between her parents, strange behavior by her friends, the pain and vulnerability of first love, a growing sense of isolation, and a surprising, rebellious new strength. With crystalline prose and the indelible magic of a born storyteller, Karen Thompson Walker gives us a breathtaking portrait of people finding ways to go on in an ever-evolving world. “Gripping drama . . . flawlessly written; it could be the most assured debut by an American writer since Jennifer Egan’s Emerald City.”—The Denver Post “Pure magnificence.”—Nathan Englander “Provides solace with its wisdom, compassion, and elegance.”—Curtis Sittenfeld “Riveting, heartbreaking, profoundly moving.”—Kirkus Reviews (starred review) Look for special features inside.

Download or read book Earth s Climate Response to a Changing Sun written by Katja Matthes and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For centuries, scientists have been fascinated by the role of the Sun in the Earth's climate system. Recent discoveries, outlined in this book, have gradually unveiled a complex picture, in which our variable Sun affects the climate variability via a number of subtle pathways, the implications of which are only now becoming clear. This handbook provides the scientifically curious, from undergraduate students to policy makers with a complete and accessible panorama of our present understanding of the Sun-climate connection. 61 experts from different communities have contributed to it, which reflects the highly multidisciplinary nature of this topic. The handbook is organised as a mosaic of short chapters, each of which addresses a specific aspect, and can be read independently. The reader will learn about the assumptions, the data, the models, and the unknowns behind each mechanism by which solar variability may impact climate variability. None of these mechanisms can adequately explain global warming observed since the 1950s. However, several of them do impact climate variability, in particular on a regional level. This handbook aims at addressing these issues in a factual way, and thereby challenge the reader to sharpen his/her critical thinking in a debate that is frequently distorted by unfounded claims.
