Recommends it for: Intelligent readers interested in general science
Isaac Asimov is best known as a science fiction author, yet nonetheless wrote far more about true science—hundreds of books, in fact. Over several decades Asimov wrote a monthly science column for the Magazine of Fantasy and Science Fiction. Many of these essays were later published in paperback form as collections.

Asimov was one of the all-time greatest explainers of science. He generally wrote for an intelligent audience of non-scientists, and so he usually started at the very beginning and bu

This book is a hard-sell. Non-fiction, sciency stuff. If you are still reading...then maybe you should give this book a try! If "Non-fiction, sciency stuff" doesn't totally scare you away, you would get a lot out of this. If you like reading Popular Science, or even National Geographic, read on...

'X' Stands for Unknowns is broken up into 5 sections (this is not to mention the introduction section which completely blew my mind! Issac Asimov is not just one of the world's greatest science fiction

I have a feeling I'm going to be reading and rating as 5 star a lot of Asimov's works. Something about his writing, style of humor, and intelligence that just connects with me. It doesn't matter what he writes about. This collection of pop science essays was wonderful. Such a treasure of knowledge in topics that include Physics, Chemistry, Astronomy, and Mathematics. If I would have known about these in high school it would have greatly improved my appreciation for the sciences and certainly mak ...more

As a collection of scientific essays, this work offers quite a bit of variety, and a fair amount of depth. Ranging from chemistry to mathematics, and from astronomy to physics and beyond, Asimov's writing balances an exploration of how we've come to know and understand facets of existence and science with questions of why the journey forward toward truth has been so important and varied, as well as with what comes next. Though some of the essays are heavy enough in the terminology of science tha ...more

This book is brilliant, I've been never interested in science but this is BLOW-MINDING. It is a collection of seventeen nonfiction science essays,my favorite was Chemistry.
My story with the book is; I had a mathematical research so I went to University’s library and found it, I was fascinated with everything. I thought it will be a good idea since the science wasn't my thing. I wanted to give it a try on something I was surely I won't like. I borrowed it for two week and it was amazing, sadly

The 17 essays in this collection were originally printed in The Magazine of Fantasy and Science Fiction. They cover topics in physics, chemistry, astronomy and mathematics. The ending essays deal with the state of science in education and religion. For the most part they covered the major developments and discoveries in these fields from their beginnings to the early 80s and are the basis for technology today. Interesting and informative.

Some nice essays on a variety of scientific subjects: the physics essays concentrate on electromagnetic radiation whilst those on chemistry discuss silicon and carbon. The last two essays contain well-needed attacks on creationism and astrology: sometimes I wish that Asimov was still around today so he could go on one of those silly religious ''debating'' programs and teach the zealots a lesson or two.

Su lectura me ha supuesto un esfuerzo de memoria y de búsqueda de términos que nunca he aprendido o ya había olvidado. Algunas partes se hacen un poco más pesadas pero en líneas generales me ha gustado, entretenido y enseñado cosas.

PAs la bonne édition, il faut corriger ça.

De la vulgarisation scientifique de qualité, mais trop simple pour quelqu'un qui possède un peu de background scientifique pré-existant.
