[Book Review] Cosmos by Carl Sagan



What is this book about?

Book explores the mutual development of science and civilization. It tries to answer what does Cosmos mean to humans? and what do humans mean for Cosmos?

Author broadly discusses history of science leading to today, our current understanding of the cosmos, possibility of life elsewhere in the universe and how does future look for the mankind.

Writing Style:

Whenever author discusses a subject, he also dwells into all the associated areas and gives a comprehensive picture. For example, to make clear the fact that life which evolves elsewhere could be radically different from us he goes into concepts of evolution of mankind and discusses the possibility for an alternate evolutionary path. While discussing future of life on earth, author discusses current global security equation, human psychology and history along with science. This book is heavy on science with pleasant doses of history, biology and other disciplines.

What to expect while reading?

Reading could demand concentration at times as author mentions many scientific details when discussing a concept. It also needs us to be imaginative especially during the chapters discussing efforts to reach Mars and Venus, life cycle of stars and some other concepts related to Celestial objects. But once we follow what author is saying, reading this will be amazing ride.

Every concept author presents is discussed in a very engaging way. Author never deviates and always relies on science to convey his point. As a result, reading this will sometimes bring recollection of many concepts of science that we once read and more often will introduce many more wonderful concepts to you. Concepts are neither too complex nor too simple. Hence making it an interesting and educating read. Chapters discussing possible boundaries of the universe and future of life on earth are my favorites.

I will remember Cosmos as the book that has taught me how beautiful science actually is.

If you have ever looked into infinity of sky at night enjoying beauty of stars and wondering what it all means, you are sure to enjoy Cosmos :)

[Short Story] The Regret

    It was 5pm in the evening. Prithvi made the big decision and started his journey downwards from the 50th floor of the bank building which is his workplace.          He has been working at a huge commercial bank for 25 years. He started as an Assistant Manager and rose to the level of Vice President of the bank for the entire region of South India. Till 2 months before today, anyone would have agreed that he had a very successful career. But all that changed in a single day.          A financial fraud of never seen proportions was exposed a couple of months earlier.

Though the investigation revealed that he was innocent, he had a bigger problem to fac...

[Opinion] Which one is better, Idealism or Realism?

    Idealism is when you envision or see things in an ideal or perfect manner. Realism, on the other hand, tends toward a more pragmatic and actual view of a situation. These two approaches are familiar to most of the us even though we are not familiar with the formal definitions of them. So which one among these is better?           We are familiar with benefits of a positive mindset. Idealism helps greatly in having a positive mindset. A person with a positive mindset will be more hopeful, motivated and at peace with his situation. Believing things like good ultimately wins over evil, every act in life has a purpose etc can help in having peaceful mind. Believing that efforts will be rewarded will keep us motivated in our work. If we can believe all people are good, then we will have no need to judge, suspect or doubt anyone's intentions. If there is a super-natural power, it will take care of all the evil and we need not worry about it. It is ...

[English Poem] Trip to Florida

I wrote the below poem while returning from a trip to Florida. We were 7 friends who visited Florida for 4 days. The poem is about our experiences on the trip. Bursts of excitement, frenzies of panic is how it started  With a plan that was never total, journey started with a day at Hollywood Looking at with surprise, we went about discovering her as Florida has a soul of its own We reached Key West feeling  it on the way, as it is more like a poem than a place  Jumping out of a plane, snorkeling like a whale  Confidence floating sky high Word impossible was invisible for a day Watching sea swallow the sun and then flaunt hats of dark clouds  Lines between dream and reality were blurred for a moment How long can you stare at a wall? How powerful is the visual art? Wynwood walls changing answers to these questions How beautiful can a beach city be? Miami mimed and said there is no limit Both turned out to be shocking discoveries  With bunch of friends around ...
