- with images and audio/video to produce effective experiences of learning
- Art and decoration with colors, nuances, transparencies and shadows
To exhibit its potential, the canvas, requires a language support such as JavaScript, and it is this language that also gives interactivity to the pages of this e-book.
This guide explores the All Controls javascript for canvas by providing the essential knowledge to the use of each of them.
For each command are showed one or more interactive examples.
This e-book, thanks to the interactivity will allow to a better appreciation of the real potentiality of the various controls and the interaction among them.

    Facing Climate Change explains why people refuse to accept evidence of a warming planet and shows how to move past partisanship to reach a consensus for action. A climate scientist and licensed Jungian analyst, Jeffrey T. Kiehl examines the psychological phenomena that twist our relationship to the natural world and their role in shaping the cultural beliefs that distance us further from nature. He also accounts for the emotions triggered by the lived experience of climate change and the feelings of fear and loss they inspire, which lead us to deny the reality of our warming planet.But it is not too late. By evaluating our way of being, Kiehl unleashes a potential human emotional understanding that can reform our behavior and help protect the Earth. Kiehl dives deep into the human brain's psychological structures and human spirituality's imaginative power, mining promising resources for creating a healthier connection to the environment—and one another. Facing Climate Change is as concerned with repairing our social and political fractures as it is with reestablishing our ties to the world, teaching us to push past partisanship and unite around the shared attributes that are key to our survival. Kiehl encourages policy makers and activists to appeal to our interdependence as a global society, extracting politics from the process and making decisions about our climate future that are substantial and sustaining.

    An enlightening look at animal behavior and the cycle of life and death, from “one of the finest naturalists of our time” (Edward O. Wilson).   When a good friend with a severe illness wrote, asking if he might have his “green burial” at Bernd Heinrich’s hunting camp in Maine, it inspired the acclaimed biologist to investigate a subject that had long fascinated him. How exactly does the animal world deal with the flip side of the life cycle? And what are the lessons, ecological to spiritual, imparted by a close look at how the animal world renews itself?   Heinrich focuses his wholly original gaze on the fascinating doings of creatures most of us would otherwise turn away from—field mouse burials conducted by carrion beetles; the communication strategies of ravens, “the premier northern undertakers”; and the “inadvertent teamwork” among wolves and large cats, foxes and weasels, bald eagles and nuthatches in cold-weather dispersal of prey. Heinrich reveals, too, how and where humans still play our ancient and important role as scavengers, thereby turning not dust to dust, but life to life.   “If it has not been clear to readers by now, this book confirms that Bernd Heinrich is one of the finest naturalists of our time. Life Everlasting shines with the authenticity and originality that are unique to a life devoted to natural history in the field.” —Edward O. Wilson, author of The Meaning of Human Existence and The Social Conquest of Earth

    Why an awareness of Earth’s temporal rhythms is critical to our planetary survival 
    Few of us have any conception of the enormous timescales in our planet’s long history, and this narrow perspective underlies many of the environmental problems we are creating for ourselves. The passage of nine days, which is how long a drop of water typically stays in Earth’s atmosphere, is something we can easily grasp. But spans of hundreds of years—the time a molecule of carbon dioxide resides in the atmosphere—approach the limits of our comprehension. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth’s deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future. 
    Marcia Bjornerud shows how geologists chart the planet’s past, explaining how we can determine the pace of solid Earth processes such as mountain building and erosion and comparing them with the more unstable rhythms of the oceans and atmosphere. These overlapping rates of change in the Earth system—some fast, some slow—demand a poly-temporal worldview, one that Bjornerud calls “timefulness.” She explains why timefulness is vital in the Anthropocene, this human epoch of accelerating planetary change, and proposes sensible solutions for building a more time-literate society. 
    This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. The lifespan of Earth may seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth’s history—and the magnitude of our effects on the planet.

    The Authorized Albert Einstein Archives Edition: An homage to the men and women of science, and an exposition of Einstein’s place in scientific history In this fascinating collection of articles and speeches, Albert Einstein reflects not only on the scientific method at work in his own theoretical discoveries, but also eloquently expresses a great appreciation for his scientific contemporaries and forefathers, including Johannes Kepler, Isaac Newton, James Clerk Maxwell, Max Planck, and Niels Bohr. While Einstein is renowned as one of the foremost innovators of modern science, his discoveries uniquely his own, through his own words it becomes clear that he viewed himself as only the most recent in a long line of scientists driven to create new ways of understanding the world and to prove their scientific theories. Einstein’s thoughtful examinations explain the “how” of scientific innovations both in his own theoretical work and in the scientific method established by those who came before him. This authorized ebook features a new introduction by Neil Berger, PhD, and an illustrated biography of Albert Einstein, which includes rare photos and never-before-seen documents from the Albert Einstein Archives at the Hebrew University of Jerusalem.

    Over the centuries, one by one, Britain's most formidable wild animals have fallen to the thoughtless march of humankind. A war on predators put paid to our lynxes, wolves and bears, each hunted relentlessly until the last of them was killed. Only our wildcats lived on. 
    The Scottish wildcat's guile and ferocity are the stuff of legend. No docile pet cat, this, but a cunning and shadowy animal, elusive to the point of invisibility, but utterly fearless when forced to fight for its life. Those who saw one would always remember its beauty – the cloak of dense fur marked with bold tiger stripes, the green-eyed stare and haughty sneer, and the broad, banded tail whisking away into the forest's gloom. 
    Driven to the remnants of Scotland's wilderness, the last few wildcats now face the most insidious danger of all as their domesticated cousins threaten to dilute their genes into oblivion. However, the wildest of cats has friends and goodwill behind it. This book tells the story of how the wildcat of the wildwood became the endangered Scottish wildcat, of how it once lived and lives now, and of how we - its greatest enemy - are now striving to save it in its darkest hour.
