A brief introduction to gravity through Einstein's general theory of relativity

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.

Can stuffed elephants go to kindergarten, too?

Sammie takes Ellie, her stuffed elephant lovey, everywhere. But stuffed animals can't come to Sammie's kindergarten. Sammie and Ellie are afraid to spend their first day apart until they learn that Ellie gets to go to her very own kindergarten in Mama's car. In car kindergarten, Ellie works on counting, writing her letters and sounding out words. Ellie has lunch in the cafeteria, and enjoys art, P.E., music and recess. And, just like in Sammie's kindergarten at school, Ellie even makes some new friends.

Through the power of imagination, Ellie's Car Kindergarten gives children a positive way to feel comfortable spending their school day apart from a lovey or special stuffed animal. Ellie's Car Kindergarten is also a creative tool parents and educators can use to help children look forward to learning and having fun in kindergarten. Ellie's Car Kindergarten is a 2018-2019 Reviewers Choice Literary Award winner.
