Textbook in PDF format

Do you know what a quasar is? Or an oceanic ridge? Or a cutting? Or the chromatography? Do you know the consequences of the second principle of Thermodynamics or why the interior of the Earth is liquid or who discovered the electron? Science and Technology have long been installed in our lives but few people have a general scientific culture. The purpose of this work is to alleviate this problem. The work is divided into six main blocks: Astronomy, Physics, Chemistry, Biology, Earth Sciences and Technology. It is based on the format of questions and answers, short most of them. It is aimed at all people who want to expand their scientific-technical knowledge, both those who studied and forgot them and those who have never seen them. The language is accessible and enjoyable. In each of the scientific disciplines, you start from a basic level of knowledge, to gradually acquire a medium-high level.
Astronomy is a fascinating science. At the dawn of humanity, the human being looked up to the starry sky, looking for supernatural explanations for everyday phenomena. Today, with very sophisticated observation instruments, the harmony of the spheres keeps on disturbing us. But the apparent celestial harmony hides a violent universe, with gigantic explosions, thermonuclear reactions and extreme temperatures. This book is a general guide for the amateur astronomer, for lovers of Astronomy and even for the completely ignorant of the subject who wants to know the ins and outs of theoretical astronomy. This volume is divided into these sections: 1. Introduction. 2. Distances and coordinates. 3. The Earth-Moon-Sun system. 4. Celestial mechanics. 5. Observation of the sky. 6. The Solar System and the Milky Way. 7. Celestial objects. 8. Astronomical phenomena. 9. Space exploration. 10. Cosmology. It contains more than 270 spectacular images (photographs and drawings) that, in addition to complementing the explanation, have an undeniable aesthetic function
