A 2021 NCTE Charlotte Huck Award Honor Book A Bank Street Best Book of 2021 Quintessence is an extraordinary story from Jess Redman about friendship, self-discovery, interconnectedness, and the inexplicable elements that make you you. Three months ago, twelve-year-old Alma moved to the town of Four Points. Her panic attacks started a week later, and they haven’t stopped—even though she’s told her parents that they have. She’s homesick and friendless and every day she feels less and less like herself. But one day she finds a telescope in the town’s junk shop, and through its lens, she watches a star—a star that looks like a child—fall from the sky and into her backyard. Alma knows what it’s like to be lost and afraid, to long for home, and she knows that it’s up to her to save the star. And so, with the help of some unlikely new friends from Astronomy Club, she sets out on a quest that will take a little bit of science, a little bit of magic, and her whole self. This title has Common Core connections.

Imagine an Age of Exploration full of alchemy, human dissection, sea monsters, betrayal, torture, religious controversy, and magic. In Europe, the magic is thin, but at the edge of the world, where the stars reach down close to the Earth, wonders abound. This drives the bravest explorers to the alluring Western Ocean. Christopher Sinclair is an alchemist who cares only about one thing: quintessence, a substance he believes will grant magical powers and immortality. And he has a ship.

Through the first half of the twentieth century, analytic philosophy was dominated by Russell, Wittgenstein, and Carnap. Influenced by Russell and especially by Carnap, another towering figure, Willard Van Orman Quine (1908Ð2000) emerged as the most important proponent of analytic philosophy during the second half of the century. Yet with twenty-three books and countless articles to his creditÑincluding, most famously, Word and Object and "Two Dogmas of Empiricism"ÑQuine remained a philosopher's philosopher, largely unknown to the general public. Quintessence for the first time collects Quine's classic essays (such as "Two Dogmas" and "On What There Is") in one volumeÑand thus offers readers a much-needed introduction to his general philosophy. Divided into six parts, the thirty-five selections take up analyticity and reductionism; the indeterminacy of translation of theoretical sentences and the inscrutability of reference; ontology; naturalized epistemology; philosophy of mind; and extensionalism. Representative of Quine at his best, these readings are fundamental not only to an appreciation of the philosopher and his work, but also to an understanding of the philosophical tradition that he so materially advanced.

Will the universe continue to expand forever, reverse its expansion and begin to contract, or reach a delicately poised state where it simply persists forever? The answer depends on the amount and properties of matter in the universe, and that has given rise to one of the great paradoxes of modern cosmology; there is too little visible matter to account for the behaviour we can see. Over 90 percent of the universe consists of 'missing mass' or 'dark matter' - what Lawrence Krauss, in his classic book, termed "the fifth essence". In this new edition of The Fifth Essence, retitled Quintessence after the now widely accepted term for dark matter, Krauss shows how the dark matter problem is now connected with two of the hottest areas in recent cosmology: the fate of the universe and the "cosmological constant." With a new introduction, epilogue and chapter updates, Krauss updates his classic and shares one of the most stunning discoveries of recent years: an antigravity force that explains recent observations of a permanently expanding universe.

"Suffused with her inimitable word play and stunning intelligence, and embodying a balance of mysticism and critical theory, Daly's clarion call to uncover the quintessence of the universe is quite an intriguing tune." -On the Issues
