Book Review – Cosmos, Carl Sagan

Cosmos, Carl Sagan (Image Source - Google)
We humans have come a long way. From the days we were wandering the planet looking little different from our primate cousins, to these modern times where we take for granted technologies that would have been equated to magic just a century or so ago, we humans have made amazing progress. Science is what brought us here and science is what is going to help us evolve in the days ahead too. Science helped us see things as they are, dispelled our fears, gave us hope, made us discover fire and invent the wheel – two of the most important findings till today.

While science may not have solved all our queries yet - and raises as many demons as it lays to rest - it makes genuine, continuous efforts to arrive at the Truth. Armed with science, we humans have started exploring all around us. From the microcosmic wonders of atoms to the mega marvels of Universe, science has lifted many veils and shown us things beyond our limited understanding. Scientists like Carl Sagan have played an important role in lifting those veils, not only by their direct contribution to the sciences, but also through their ability to communicate such esoteric wisdom to the masses, to laymen that are keen on understanding their surroundings but limited in their ability to do so.

Books like ‘The Origin of Species’ remain special, not just because they tell us about groundbreaking discoveries, but also due to their telling it in a language that we, the laypersons, can understand. While ‘Cosmos’ by Carl Sagan may not be as earth-shattering as ‘The Origin of Species’, it is special by its own right. Written nearly four decades ago, co-developed with a television series of the same name, this book was produced with the idea of popularizing the sciences, especially astronomy, among the masses. To the uninitiated but curious mind, this book is the ideal beginning into the wonderous realms of the cosmos. This book is to the budding astronomer what the alphabets and the arithmetic are to the young child.

From the ancient budding of scientific thoughts at the Ionian islands to the then-latest launching of space missions like Voyager-2, Carl Sagan takes each stage in the evolution of science as we know it, elaborates on the circumstances prevailing at those times, enumerates important contributions by various scientists. The real fun is his doing all this in an interesting, pacey manner, without letting the reader feel bored even once. After helping us navigate the unimaginably vast expanse of our Universe and showing us the wonders of our solar system, stars, planets, galaxies and the bleak black holes along the way, Sagan ends the book with philosophical musings on the future of mankind on this nuclear era and the possibilities of our encountering extra-terrestrial intelligence.

This is not just a book on astronomy. Burgeoning with interesting details on history, evolution, atomic science and mathematics, this is one complete book that every mind passionate about learning must possess.
