Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. His stick-figure drawings about science, technology, language, and love have a large and passionate following. Fans of xkcd ask Munroe a lot of strange questions. What if you tried to hit a baseball pitched at 90 percent of the speed of light? How fast can you hit a speed bump while driving and live? If there were a robot apocalypse, how long would humanity last?

For any task you might want to do, there's a right way, a wrong way, and a way so monumentally complex, excessive, and inadvisable that no one would ever try it. How To is a guide to the third kind of approach. It's full of highly impractical advice for everything from landing a plane to digging a hole.

The millions of people around the world who loved What If? still have questions, and those questions are getting stranger. Thank goodness xkcd creator Randall Munroe is here to help. Planning to ride a fire pole from the Moon back to Earth? The hardest part is sticking the landing. Hoping to cool the atmosphere by opening everyone’s freezer door at the same time? Maybe it’s time for a brief introduction to thermodynamics. Want to know what would happen if you rode a helicopter blade, made a lava lamp out of lava, or jumped on an erupting geyser? Okay, if you insist.

A manned mission to Mars has been the dream of humanity at least since the 19th century, when we first saw details of the surface and thought there might be canals filled with water there. Here I’ve looked at the history of unmanned exploration of Mars over the last 50-plus years, proposed missions to Mars, Mars settlements, and other major issues regarding traveling to and living on Mars. Some proposals have lots of details of proposed scenarios, if you want to know all of the engineering and scientific analysis work.

Earth evolves. From first atom to molecule, mineral to magma, granite crust to single cell to verdant living landscape, ours is a planet constantly in flux. In this radical new approach to Earth’s biography, senior Carnegie Institution researcher and national best-selling author Robert M. Hazen reveals how the co-evolution of the geosphere and biosphere - of rocks and living matter - has shaped our planet into the only one of its kind in the Solar System, if not the entire cosmos.

Animals plainly know where they're going, but how they get there has remained surprisingly mysterious - until now. In Supernavigators, award-winning author David Barrie catches us up on the cutting-edge science. Here are astounding animals of every stripe: Dung beetles that steer by the light of the Milky Way. Ants and bees that rely on patterns of light invisible to humans. Sea turtles and moths that find their way using Earth's magnetic field. Humpback whales that swim thousands of miles while holding a rock-steady course.

Innovation starts with a problem whose solution sets in motion all kinds of unexpected discoveries. That's why you can draw a line from pendulums to punching the clock at a factory, from ice blocks to summer movie blockbusters, from clean water to computer chips. In the lively storytelling style that has made him a popular, best-selling author Steven Johnson looks at how accidental genius, brilliant mistakes, and unintended consequences shape the way we live in the modern world.

There is a growing crisis in our oceans as rates of infectious disease outbreaks are on the rise. A warmer world is a sicker world for humans and wild biota. Marine epidemics have caused mass die-offs of wildlife from the bottom to the top of the food chains, impacting the health of ocean ecosystems as well as lives on land. Fueled by a warming ocean and accelerated by sewage dumping, unregulated aquaculture, and drifting plastic, ocean outbreaks are sentinels of impending global environmental disaster.

Teeming with unsuspected life, an extraordinary, interconnected ecosystem deep below the waves has a huge effect on our daily lives, influencing climate and weather systems, with the potential for much more—good or bad, depending on how it is exploited. Currently, the fantastic creatures that live in the deep—many of them incandescent in a world without light—and its formations capture and trap vast quantities of carbon that would otherwise poison our atmosphere, and novel bacteria as yet undiscovered hold the promise of potent new medicines.

Well, Cool Earth Facts for Kids has all of those facts and more! Made for kids eight and up, and younger ambitious learners, this audiobook breaks down all of the planet's coolest and most interesting processes! Designed to help create a foundation for a broad understanding of Earth's natural history and functions, this audiobook includes chapters on the following:

In Storm in a Teacup, Helen Czerski provides the tools to alter the way we see everything around us by linking ordinary objects and occurrences, like popcorn popping, coffee stains, and fridge magnets, to big ideas like climate change, the energy crisis, and innovative medical testing.

Beyond dares to imagine a fantastic future for humans in space - and then reminds us that we're already there. Human exploration has been an unceasing engine of technological progress, from the first homo sapiens to leave our African cradle to a future in which mankind promises to settle another world. Beyond tells the epic story of humanity leaving home - and how humans will soon thrive in the vast universe beyond the Earth.

Jellyfish are an enigma. They have no centralized brain, but they see and feel and react to their environment in complex ways. They look simple, yet their propulsion systems are so advanced that engineers are just learning how to mimic them. They produce some of the deadliest toxins on the planet and still remain undeniably alluring. Long ignored by science, they may be a key to ecosystem stability. Juli Berwald's journey into the world of jellyfish is a personal one.

Biomimicry, the science of employing nature to advance sustainable technology, is arguably one of the hottest new business concepts. At the center of this growing movement has been award-winning inventor and biomimetic entrepreneur Jay Harman.

In Beyond Earth, the authors offer groundbreaking research and argue persuasively that not Mars but Titan - a moon of Saturn with a nitrogen atmosphere, a weather cycle, and an inexhaustible supply of cheap energy, where we will be able to fly like birds in the minimal gravitational field - offers the most realistic and thrilling prospect of life without support from Earth.
