On the freezing-cold morning of 28 January 1986, the space shuttle Challenger broke apart over the Atlantic Ocean, killing all seven people on board. Millions around the world witnessed the tragic deaths of the crew, which included New Hampshire schoolteacher Christa McAuliffe. Yet the full story of what happened that day - and the ominous warning signs recognised but then ignored in the years before - has never been told.
Following a handful of central protagonists - from the astronauts and their families to the rocket engineers who tried to stop the fateful launch - Challenger a gripping tale of human overreach; of cynicism and cost cutting; of hubristic 'go fever'; and of an investigation driven by heroic whistle-blowers determined to bring the truth to light. Blending human dram with fascinating science and political infighting, Challenger is a masterpiece of non-fiction storytelling. The result is a story even more extraordinary and terrifying than any of us remembered - or thought possible.

Astronomers have long known that the Universe is expanding, but everything they could see indicated that gravity should be slowing this spread. Instead, it appears that the Universe is accelerating its expansion and that something stronger than gravity --dark energy -- is at work. In Einstein's Telescope Evalyn Gates, a University of Chicago astrophysicist, transports us to the edge of contemporary science to explore the revolutionary tool that unlocks the secrets of these little-understood cosmic constituents. Based on Einstein's theory of general relativity, gravitational lensing, or "Einstein's Telescope," is enabling new discoveries that are taking us toward the next revolution in scientific thinking -- one that may change forever our notions of where the Universe came from and where it is going.$54.95
The common language of genius: Eureka! While the roads that lead to breakthrough scientific discovery can be as varied and complex as the human mind, the moment of insight for all scientists is remarkably similar. The word "eureka!", attributed to the ancient Greek mathematician Archimedes, has come to express that universal moment of joy, wonder-and even shock-at discovering something entirely new. In this collection of twelve scientific stories, Leslie Alan Horvitz describes the drama of sudden insight as experienced by a dozen distinct personalities, detailing discoveries both well known and obscure. From Darwin, Einstein, and the team of Watson and Crick to such lesser known luminaries as fractal creator Mandelbrot and periodic table mastermind Dmitri Medellev, Eureka! perfectly illustrates Louis Pasteur's quip that chance favors the prepared mind. The book also describes how amateur scientist Joseph Priestley stumbled onto the existence of oxygen in the eighteenth century and how television pioneer Philo Farnsworth developed his idea for a TV screen while plowing his family's Idaho farm.$19.95

Assemble your own moving solar system!
Set the planets I motion with a flick of your wrist! Build a mechanical model of the solar system including the sun and eight planets (also known as an orrery,) wind it up, and watch the planets revolve around the sun. Assemble this complex machine using snap-together plastic parts to learn how the gears and windup mechanism work to spin the model. Detail each planet with colourful, realistic-looking printed planet graphics. Discover how a special type of gear called a planetary gear is used to stimulate the mesmerizing motion of the solar system. Learn about the order of the planets, their relative sizes, their rates of revolution around the sun, their appearance, and other planetary facts. Bonus: There's a built-in expansion slot in case the mysterious Planet Nine is discovered! This kit includes full-colour step-by-step illustrated assembly instructions.
