Book Description
The mystery of Earth's invisible, life-supporting power Alanna Mitchell's globe-trotting history of the science of electromagnetism and the Earth's magnetic field--right up to the latest indications that the North and South Poles may soon reverse, with apocalyptic results--will soon change the way you think about our planet. Award-winning journalist Alanna Mitchell's science storytelling introduce intriguing characters--from the thirteenth-century French investigations into magnetism and the Victorian-era discover that electricity and magnetism emerge from the same fundamental force to the latest research. No one has ever told so eloquently how the Earth itself came to be seen as a magnet, spinning in space with two poles, and that those poles have dramatically reversed many time, often coinciding with mass extinctions. The most recent reversal was 780,000 years ago. Mitchell explores indications that the Earth's magnetic force field is decaying faster than previously thought. When the poles switch, a process that takes many years, the Earth is unprotected from solar radiation storms that would, among other disturbances, wipe out much and possible all of our electromagnetic technology. Navigation for all kinds of animals is disrupted without a stable, magnetic North Pole. But can you imagine no satellites, no Internet, no smartphones--maybe no power grids at all? Alanna Mitchell offers a beautifully crafted narrative history of surprising ideas and science, illuminating invisible parts of our own planet that are constantly changing around us.

Book Description
Fully-illustrated and with a fun and innovative flip-book format, the book provides the perfect way to explore and compare the extreme environments of the two Poles. Take a trip to the ends of the earth and discover the extreme environments of the North and South Poles. Find out which animals live where, what the weather and climate is like and the effect global warming is having. Beginning with the North Pole, the book introduces the geography and climate of the Arctic. Readers will discover how climate change is affecting sea ice and why multi-year ice is so important to walruses and polar bears. Find out what ice floes are and what lives under the ice. The many uses of the Arctic are explained, from the home it provides to whale hunters to the rocket and missile test sites it houses. And then flip the book over and you arrive in the South Pole… The famous race to reach the Pole in 1911 is retold and readers will discover why the orca is the ultimate polar predator. The huge tabular icebergs, sub-glacial lakes and ice chimneys of the Antarctic are brought to life in all their impressive glory, not to mention the sea spiders, 'death star' starfish and other undersea giants!

Book Description
In 1960, author Larry Lee knew he needed to make a decision. A high school student in Kansas City, he had a girlfriend and some great buddies. He wasnt ready to head to college and had no idea what he wanted to do in life. With the political climate at the time, he realized he must join the service or be drafted. Between the Poles shares a journal of the who, what, when, why, and what-for epilogue of his four adventurous years in the US Navy. It was during this time he was transformed from a kid into a hard-working, tax-paying young adult. The story stems from keeping a daily log of his experiences in and with Operation Deepfreeze 63 in Antarctica aboard the USS Staten Island (AGB-5). Written through a young sailors eyes, this fun, lighthearted story describes Lees adventures on an icebreaker in the Navy, sailing between Seattle, Antarctica, and the Arctic Circle where he traveled tens of thousands of miles, endured good times and bad times, and created lifelong friendships.

Book Description
Winner of the National Outdoor Book Award From the Pulitzer Prize-winning historian, a "suspenseful" (WSJ) and "adrenaline-fueled" (Outside) entwined narrative of the most adventurous year of all time, when three expeditions simultaneously raced to the top, bottom, and heights of the world. As 1909 dawned, the greatest jewels of exploration—set at the world’s frozen extremes—lay unclaimed: the North and South Poles and the so-called “Third Pole,” the pole of altitude, located in unexplored heights of the Himalaya. Before the calendar turned, three expeditions had faced death, mutiny, and the harshest conditions on the planet to plant flags at the furthest edges of the Earth. In the course of one extraordinary year, Americans Robert Peary and Matthew Henson were hailed worldwide at the discovers of the North Pole; Britain’s Ernest Shackleton had set a new geographic “Furthest South” record, while his expedition mate, Australian Douglas Mawson, had reached the Magnetic South Pole; and at the roof of the world, Italy’s Duke of the Abruzzi had attained an altitude record that would stand for a generation, the result of the first major mountaineering expedition to the Himalaya's eastern Karakoram, where the daring aristocrat attempted K2 and established the standard route up the most notorious mountain on the planet. Based on extensive archival and on-the-ground research, Edward J. Larson weaves these narratives into one thrilling adventure story. Larson, author of the acclaimed polar history Empire of Ice, draws on his own voyages to the Himalaya, the arctic, and the ice sheets of the Antarctic, where he himself reached the South Pole and lived in Shackleton’s Cape Royds hut as a fellow in the National Science Foundations’ Antarctic Artists and Writers Program. These three legendary expeditions, overlapping in time, danger, and stakes, were glorified upon their return, their leaders celebrated as the preeminent heroes of their day. Stripping away the myth, Larson, a master historian, illuminates one of the great, overlooked tales of exploration, revealing the extraordinary human achievement at the heart of these journeys.

Book Description
This book discusses ground-pole training for all disciplines and shows how you can make the most of precious schooling time. It provides quick and easy pole layouts, using just a handful of poles. Different exercises are given for each pole layout, so there is no need to move the poles during a session. Exercises range from the simple to the more intricate, with the inclusion of more transitions, lateral work, raised poles/cavalletti, or riding in a different gait. Claire Lilley explains how these pole exercises can help you to ride with precision and improve your horse's way of going, adhering to the scales of training. You can also use the different layouts to check whether you are sitting straight, turning correctly, and riding transitions and lateral movements properly. She lists common rider faults for each exercise to help riders self-correct if schooling alone. As an experienced trainer herself, Claire knows that this book will prove an invaluable resource for riding instructors, providing a veritable cookbook of ideas for lesson plans. Poles are a great teaching tool, adding variety to every lesson and helping the teacher to explain lessons to the pupil. Teacher's tips are given for each exercise. Claire says: "Try the exercises for yourself and I'm sure you will be amazed at the improvements that can be made both in your riding technique and in your horse's way of going. You will never be bored with schooling again!"
