    This fictionalized version of a true story emphasizes the importance of artistic vision and personal resilience. Editorial Reviews In fifteenth century Florence, a contest is announced for the best design of a dome for the Cathedral of Santa Maria del Fiore. Filippo Brunelleschi, a goldsmith called Pippo the Fool for his practice of designing peculiar machines and structures, vows to win. No one has been able to figure out how to build a dome of the necessary size. Pippo studies the problem and prepares sketches. The contest judges eliminate him. But he builds a model, and the judges are impressed. However, to his anger, they insist that he work with the sneering, arrogant Lorenzo Ghilberti. Overcoming his pride, Pippo begins. It takes sixteen years to finish—without Ghilberti—but the result is the marvel we can see today. Estrada takes pains to depict Florence with historic thoughtfulness. At the same time, his characters are effectively humorous. Lorenzo is depicted with foolish bravado, while Pippo has youthful arrogance. The detailed watercolor-and-gouache scenes with crowds of citizens are informative as well as attractive; the images of the building in process and finished at last are truly impressive. Notes by both author and illustrator add factual information. Includes a list of resources for those who want to learn more. Reviewer: Ken Marantz and Sylvia Marantz

    Henrietta spent years measuring star positions and sizes from photographs taken by the telescope at the Harvard College Observatory, where she worked. After Henrietta observed that certain stars had a fixed pattern to their changes, her discovery made it possible for astronomers to measure greater and greater distances—leading to our present understanding of the vast size of the universe.An astronomer of her time called Henrietta Leavitt “one of the most important women ever to touch astronomy,” and another close associate said she had the “best mind at the Harvard Observatory.” Henrietta Leaveitt's story will inspire young women and aspiring scientists of all kinds and includes additional information about the solar system and astronomy.

    Just about everyone has at least heard of Albert Einstein's formulation of 1905, which came into the world as something of an afterthought. But far fewer can explain his insightful linkage of energy to mass. David Bodanis offers an easily grasped gloss on the equation. Mass, he writes, "is simply the ultimate type of condensed or concentrated energy," whereas energy "is what billows out as an alternate form of mass under the right circumstances." Just what those circumstances are occupies much of Bodanis's book, which pays homage to Einstein and, just as important, to predecessors such as Maxwell, Faraday, and Lavoisier, who are not as well known as Einstein today. Balancing writerly energy and scholarly weight, Bodanis offers a primer in modern physics and cosmology, explaining that the universe today is an expression of mass that will, in some vastly distant future, one day slide back to the energy side of the equation, replacing the "dominion of matter" with "a great stillness"--a vision that is at once lovely and profoundly frightening. Without sliding into easy psychobiography, Bodanis explores other circumstances as well; namely, Einstein's background and character, which combined with a sterling intelligence to afford him an idiosyncratic view of the way things work--a view that would change the world. --Gregory McNamee
