Philosophers and poets in times past tried to figure out why the stainless moon "smoothly polished, like a diamond" in Dante's words, had stains. The agreed solution was that, like a mirror, it reflected the imperfect Earth. Today we smile, but it was a clever way to understand the Moon in a manner that was consistent with the beliefs of their age. The Moon is no longer the "in" thing. We see it as often as the Sun and give it little thought - we've become indifferent. However, the Moon does reflect more than just sunlight. The Moon, or more precisely the nomenclature of lunar craters, still holds up a mirror to an important aspect of human history. Of the 1586 craters that have been named honoring philosophers and scientists, only 28 honor a woman. These 28 women of the Moon present us with an opportunity to meditate on this gap, but perhaps more significantly, they offer us an opportunity to talk about their lives, mostly unknown today.

This book tries to look at human thought and action from a scientific perspective, and in the process, acquaints the reader with essential concepts about science and its history. It takes a broad look at our present troubles without overlooking some crucial historical, religious, and political causes but places science at the center stage.The author applies what he has learned throughout his career to go beyond science. After an introduction setting the scene and a review of the 'scientific temper' and the inexcusable ignorance of science by some leaders and many followers, the author turns his sharp vision to look at other issues. The most significant challenges are critical and global: climate change caused by our activities, stockpiles of nuclear weapons that are a constant threat, population growth, and increasing inequality at all levels. These problems do have a profound ethical character and threaten to end forever with our misery, producing a 'catastrophic convergence'.Written with rigor for all readers, with many references and infused with relevant quotations, the author's message is clear: we need to change our ways drastically and urgently, now or never. But he offers not much in terms of a solution, something done by many authors to sweeten the pill, because as he argues, beyond lofty declarations, there is no real solution as the clock runs down, leading to his dystopian view of the future.

Are we alone in the Universe? What is our place in it? How did we get here? We have long searched for the answers to questions such as these, and scientists are beginning to find some of the answers. In this beautifully illustrated book, Daniel Altschuler provides the reader with the elements to understand the questions and their answers as far as we know them. He explores subjects from physics and astronomy, to geology and paleontology. Along the way he touches on topics such as the search for life on other worlds and the hazards of asteroid impacts. Written in an engaging and readable style, readers will be intrigued by the surprising connections among the stars, our planet, and life itself. Daniel Altschuler is Director of the Arecibo Observatory in Arecibo, Puerto Rico, the site of the world's largest single-dish radio telescope.
