"Of the four fundamental forces of nature, gravity might be the least understood and yet the one with which we are most intimate. From the months each of us spent suspended in the womb anticipating birth to the moments when we wait for sleep to transport us to other realities, we are always aware of gravity. In On Gravity, physicist A. Zee combines profound depth with incisive accessibility to take us on an original and compelling tour of Einstein's general theory of relativity. Inspired by Einstein's audacious suggestion that spacetime could ripple, Zee begins with the stunning discovery of gravity waves. He goes on to explain how gravity can be understood in comparison to other classical field theories, presents the idea of curved spacetime and the action principle, and explores cutting-edge topics, including black holes and Hawking radiation. Zee travels as far as the theory reaches, leaving us with tantalizing hints of the utterly unknown, from the intransigence of quantum gravity to the mysteries of dark matter and energy. Concise and precise, and infused with Zee's signature warmth and freshness of style, On Gravity opens a unique pathway to comprehending relativity and gaining deep insight into gravity, spacetime, and the workings of the universe"--Publisher's website.

**As seen on Top Gear** 'Richard Browning is a real-life Tony Stark.' - Wired --------------- For fans of Adrian Newey, Guy Martin and Chris Hadfield, in Taking on Gravity inventor Richard Browning tells the inspiring story behind his iconic jet suit, and shares his creative principles for generating true innovation. From Icarus to Iron Man, the dream of human flight has always inspired and challenged us. Now, with his pioneering jet suit, Richard Browning has redefined what is possible. Richard Browning's story is one of groundbreaking innovation. Building an aviation business from his garage, he has invented a whole new form of personal flight - a fantasy previously reserved for the pages of science fiction. His iconic jet suit has captured the imaginations of millions around the world, triggered ongoing developments in technology and engineering, and inspired a new generation of creative minds to pursue their dreams. In Taking on Gravity, Browning reveals the creative principles of his multimillion-pound company, Gravity Industries, and shows us how grass-roots innovation can disrupt established industries in exciting and unexpected ways. On this journey into the sky we'll experience what it's like to take flight, to test the limits of the human body, and to convert moonshot ideas into tangible results. The Gravity story is an inspiring example of human creativity and our ceaseless desire to push the boundaries of what is possible. Where we go next is up to you. READERS LOVE THE 'TAKING ON GRAVITY' STORY ***** 'Tony Stark Lite' ***** 'Must read for anyone looking for inspiration to continue pursuing their dream' ***** 'Taking on Gravity by Richard Browning is equal parts inspiring, inquisitive, soulful and ultimately a fantastic read that I will return to again.'

Ellie Gold is an orthodox Jewish teenager living in Toronto in the late eighties. Ellie has no doubts about her strict religious upbringing until she falls in love with another girl at her grandmother's cottage. Aware that homosexuality clashes with Jewish observance, Ellie feels forced to either alter her sexuality or leave her community. Meanwhile, Ellie's mother, Chana, becomes convinced she has a messianic role to play, and her sister, Neshama, chafes against the restrictions of her faith. Ellie is afraid there is no way to be both gay and Jewish, but her mother and sister offer alternative concepts of God that help Ellie find a place for herself as a queer Jew.
