Young readers will learn about principle aspects of nature including animals, materials, water, and weather

"Look up to the sky and make observations with Mr. Cruz's class. From day to night, moon phases, and constellations, there are lots of exciting patterns in outer space that impact life on Earth"--

Every day the sun moves across the sky and it is light. You can see clouds, birds and airplanes in the daytime. Every night the moon moves across the sky and it becomes dark. You can see stars at night. This nonfiction Beginning-to-Read book contains high-frequency words and content vocabulary. Connecting Concepts pages include a word list along with activities to strengthen early science and literacy skills, such as understanding nonfiction text, science in the real world, science and academic language, fluency, and finding further information. Aligns with Next Generation Science Standards for Grades K-3.

“A satire of writerly ambition wrapped in a psychological thriller . . . An homage to Patricia Highsmith, Oscar Wilde and Edgar Allan Poe, but its execution is entirely Boyne’s own.”—Ron Charles, The Washington Post NAMED ONE OF THE BEST BOOKS OF THE YEAR BY THE WASHINGTON POST AND MINNEAPOLIS STAR TRIBUNE Maurice Swift is handsome, charming, and hungry for fame. The one thing he doesn’t have is talent—but he’s not about to let a detail like that stand in his way. After all, a would-be writer can find stories anywhere. They don’t need to be his own. Working as a waiter in a West Berlin hotel in 1988, Maurice engineers the perfect opportunity: a chance encounter with celebrated novelist Erich Ackermann. He quickly ingratiates himself with the powerful – but desperately lonely – older man, teasing out of Erich a terrible, long-held secret about his activities during the war. Perfect material for Maurice’s first novel. Once Maurice has had a taste of literary fame, he knows he can stop at nothing in pursuit of that high. Moving from the Amalfi Coast, where he matches wits with Gore Vidal, to Manhattan and London, Maurice hones his talent for deceit and manipulation, preying on the talented and vulnerable in his cold-blooded climb to the top. But the higher he climbs, the further he has to fall. . . . Sweeping across the late twentieth century, A Ladder to the Sky is a fascinating portrait of a relentlessly immoral man, a tour de force of storytelling, and the next great novel from an acclaimed literary virtuoso. Praise for A Ladder to the Sky “Boyne's mastery of perspective, last seen in The Heart's Invisible Furies, works beautifully here. . . . Boyne understands that it's far more interesting and satisfying for a reader to see that narcissist in action than to be told a catchall phrase. Each step Maurice Swift takes skyward reveals a new layer of calumny he's willing to engage in, and the desperation behind it . . . so dark it seems almost impossible to enjoy reading A Ladder to the Sky as much as you definitely will enjoy reading it.”—NPR “Delicious . . . spins out over several decades with thrilling unpredictability, following Maurice as he masters the art of co-opting the stories of others in increasingly dubious ways. And while the book reads as a thriller with a body count that would make Highsmith proud, it is also an exploration of morality and art: Where is the line between inspiration and thievery? To whom does a story belong?”—Vanity Fair

This book gives a survey of astrophysics at the advanced undergraduate level, providing a physics-centred analysis of a broad range of astronomical systems. It originates from a two-semester course sequence at Rutgers University that is meant to appeal not only to astrophysics students but also more broadly to physics and engineering students. The organisation is driven more by physics than by astronomy; in other words, topics are first developed in physics and then applied to astronomical systems that can be investigated, rather than the other way around. The first half of the book focuses on gravity. The theme in this part of the book, as well as throughout astrophysics, is using motion to investigate mass. The goal of Chapters 2-11 is to develop a progressively richer understanding of gravity as it applies to objects ranging from planets and moons to galaxies and the universe as a whole. The second half uses other aspects of physics to address one of the big questions. While “Why are we here?” lies beyond the realm of physics, a closely related question is within our reach: “How did we get here?” The goal of Chapters 12-20 is to understand the physics behind the remarkable story of how the Universe, Earth and life were formed. This book assumes familiarity with vector calculus and introductory physics (mechanics, electromagnetism, gas physics and atomic physics); however, all of the physics topics are reviewed as they come up (and vital aspects of vector calculus are reviewed in the Appendix).
