Science Geography

Explore the Keystone State! Learn about Pennsylvania's history, geography, weather, people, and more in this book that's all about our second state.

When did the first humans arrive in India and how did they get here? What are Roman artifacts from hundreds of years ago doing in a town near Puducherry? How did merchants from Arabia end up near Kochi? From the east coast of Africa to Australia, one big blue body of water has connected diverse peoples and cultures for thousands of years: the incredible Indian Ocean. Listen in to learn about the fearless travelers and sailors, pirates and conquerors who set out to cross the ocean in search of gold and glory, and discover how geography can shape the course of history.

Human history mirrors the history of climate change. Human origins, for example, can be traced to five million years ago when the climate of East Africa became progressively hotter and drier. This caused the lush tropical jungles to disappear and be replaced by arid plains and savannahs. Our pre-human ancestors learned to exploit those new ecosystems by gathering the seed-bearing grasses, nuts, and tubers that thrived in these semi-arid conditions. Also, by foraging in the heat of the day, proto-humans could minimize unwelcome contact with nocturnal predators.

Throughout history, people have experimented, invented, and created new ways of doing things. Kid Innovators tells the stories of a diverse group of brilliant thinkers in fields like technology, education, business, science, art, and entertainment, reminding us that every innovator started out as a kid. Florence Nightingale rescued baby mice, Alan Turing was a daydreamer with terrible handwriting, and Alvin Ailey felt like a failure at sports.

The planet says we consume too much: in North America, we burn the Earth's resources at a rate five times faster than they can regenerate. And despite our efforts to "green" our consumption - by recycling, increasing energy efficiency, or using solar power - we have yet to see a decline in global carbon emissions.

The town of Journey's End may not literally be at the end of the world, but it sure feels like it to Nolie Stanhope. Spending the summer with her scientist father in the tiny Scottish village isn't exactly Nolie's idea of a good time, but she soon finds a friend: Native Journey's Ender Bel McKissick. While Nolie's father came to Journey's End to study the Boundary - a mysterious fog bank offshore - Bel's family can't afford to consider it a threat.

Veganism as an ethics and a practice has a recorded history dating back to Antiquity. Yet, it is only recently that researchers have begun the process of formalizing the study of veganism. Whereas occasional publications have recently emerged from sociology, history, philosophy, cultural studies, or critical animal studies, a comprehensive geographical analysis is missing. Until now.

Is geography really destiny? Our maps may no longer be stalked by dragons and monsters, but our perceptions of the world are still shaped by geographic myths. Myths like Europe being the centre of the world. Or that border walls are the solution to migration. Or that Russia is predestined to threaten its neighbours. In his punchy and authoritative book, Paul Richardson challenges recent popular accounts of geographical determinism and shows that how we see the world represented often isn't how it really is - that the map is not the territory.

Deniers of climate change sometimes quip that claims about global warming are more about political science than climate science. They are wrong on the science, but may be right with respect to its political implications. A hotter world, writes Andrew Guzman, will bring unprecedented migrations, famine, war, and disease. It will be a social and political disaster of the first order.

Earth Science experiments pertaining to changes on Earth, including plate tectonics, erosion, the greenhouse effect, and glaciers. An engaging way to support the Next Generation Science Standards. Experiments are simple, accessible, and something that could be used at a science fair, in the classroom, or at home. Exploring changes on Earth has never been simpler.

Gerald of Wales, also called Giraldus Cambrensis or Gerald De Barri ( c. 1146-c. 1223), was the archdeacon of Brecknock and a historian whose accounts of late 12th century Britain and France contain vivid anecdotes about the Christian church, the universities of Paris and Oxford, and about notable clerics. His work, Topographia Hiberniae, is an arresting account of his travels in Ireland, with vivid descriptions of the island’s fauna and flora and its natural beauty.

The Four Points of the Compass takes the listener on a journey of directional discovery. Jerry Brotton reveals why Hebrew culture privileges east; why Renaissance Europeans began drawing north at the top of their maps; why the early Islam revered the south; why the Aztecs used five colour-coded cardinal directions; and why no societies, primitive or modern, have ever oriented themselves westwards. He ends by reflecting on our digital age in which we, the little blue dot on the screen, have become the most important compass point.

At a time when Google Maps can take you on a virtual tour of Yosemite's remotest trails and cell phones double as navigational systems, it's hard to imagine there's any uncharted ground left on the planet. In Unruly Places, Alastair Bonnett goes to some of the most unexpected, offbeat places in the world to reinspire our geographical imagination. Bonnett's remarkable tour includes moving villages, secret cities, no man's lands, and floating islands.

In humanity’s more than 100,000 year history, we have evolved from vulnerable creatures clawing sustenance from Earth to a sophisticated global society manipulating every inch of it. In short, we have become the dominant animal. Why, then, are we creating a world that threatens our own species? What can we do to change the current trajectory toward more climate change, increased famine, and epidemic disease?

When on land, rivers, lakes, and oceans appear flat. With the aid of satellites, these bodies of water appear to have many designs! Explore the art of nature and how satellites detect the temperature of the many bodies of water around the globe.

In November 1956, a unified Telugu-speaking state of Andhra Pradesh came into being. In February 2014, Parliament bifurcated it to create two Telugu-speaking states: Telangana and Andhra Pradesh. Old History, New Geography provides the context, text and subtext to the bifurcation, which continues to be contentious and controversial.

Geologists have amassed data that indicate that islands have disappeared in the Pacific, a phenomenon that oral traditions of many groups of Pacific Islanders also highlight. This book explores the issue of vanished islands in the Pacific by bringing together the geology and the myths.

Give beginning listeners all the need-to-know information about hills, including their characteristics, how they form, and where they can be found around the world.

Kai and Kishi share the same futon, the same face, and the same talent for pearl diving. But Kishi is the obedient daughter, while Kai tries to push the rules, and sometimes they fight. Still, when Kishi is stolen and killed by the legendary Ghost Whale, nothing will stop Kai from searching for her, deep in the ocean, hoping for a way to bring her back to life. But such a rescue is beyond the power of an ordinary mortal. Kai strikes a deal with the gods: she’ll steal a magic pearl in exchange for her sister’s soul.

It was a watershed year for Canada and the world. 1945 set Canada on a bold course into the future. A huge sense of relief marked the end of hostilities. Yet there was also fear and uncertainty about the perilous new world that was unfolding in the wake of the American decision to use the atomic bomb to bring the war in the Pacific to a dramatic halt.
