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 becomeindifferent. 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 28women 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.

For a long time I have been giving scientific lectures in different countries and on diverse topics, generally related to astronomy and to my work at the Arecibo Observatory. No matter which parti- lar topic I am talking about, the same question always comes up: Have we had any contact at Arecibo with “them”? My negative answer does not satisfy anyone. In fact, the answer either confirms their suspicions that there is a conspiracy afoot by higher autho- ties not to release information or their intentions to deceive the general public. The reasons for the deception have to do with the idea that, as in the movie Contact, the received messages contain important and useful information that will bring great advantage to whoever gets it. Many of us want to believe that extraterrestrial creatures can talk to us, that perhaps they are even living among us, as UFO fans believe. It would be fascinating if it were true, a more than extra- dinary discovery, the answer to an eternal question. There is p- sibly a deep psychological motive in this desire to know if we are alone in this huge universe, and the need to believe in something beyond our limited world, in space and time. There is no doubt, then, that this topic brings with it many scientific and philosophical discussions, as well as speculations that, on many occasions, fall into pure pseudoscience because of the lack of a reference framework.

Desde Eratóstenes hasta nuestro días, el largo e ingenioso viaje de la humanidad en el intento de medir el universo.Los científicos de la Antigüedad lograron prodigiosas hazañas al obtener algunas estimaciones preliminares del tamaño de nuestro planeta y la distancia de los astros más importantes. Su trabajo estimuló a las generaciones que los siguieron, dotadas de mejores herramientas matemáticas e instrumentos más precisos, quienes no obstante se enfrentaron a un difícil puzle lógico: hay una curiosa simetría en la medición del cielo y la de la Tierra.Para determinar la posición geográfica, la distancia entre dos localizaciones o incluso el tamaño de la propia Tierra era imprescindible realizar mediciones de los astros, como hallar la altura de una estrella. Pero esa relación era recíproca, y estimar la posición y la distancia a los astros solo era posible mediante mediciones que tuvieran a la propia Tierra como patrón de medida o conociendo con detalle la distancia entre dos lugares de observación. No era posible la geografía de precisión sin la astronomía, ni viceversa.En este fascinante libro veremos cómo las distancias en cualquiera de los dos sistemas se pudieron obtener con cierta sencillez en valores relativos. Sin embargo, costó mucho esfuerzo pasar a un sistema de magnitudes absolutas que nos permitiera acceder a las complejas mediciones actuales.
