Contact by Carl Sagan


ContactContact by Carl Sagan

My rating: 5 of 5 stars

You need at least a minor background in science to understand the themes and terminology. But it’s worth it.

Contact – the movie – is one of my all-time favourite sci-fi films. It’s a slow burner, and full of political machinations, but the payoff is quite profound. The book is very similar in tone and the story is basically the same, however some events happen to different people, the time period begins some years before the setting of the movie (but spans a greater time period in total), therefore impacting the technology involved in the narrative, some characters are involved less heavily than they were portrayed in the movie, and relationships differ greatly. In my opinion, I think the book has greater realism compared to the movie, simply because it focuses more on the science, the mathematics, and the ingenuity of the people involved in decoding the “message” and building the “machine”.

Eleanor Arroway is a brilliant scientist working on the SETI – Search for Extraterrestrial Intelligence. Using radio telescopes, she and her team search the skies for possible transmissions from outer space, from potentially advanced civilisations in the far reaches of the universe. A signal is received containing a questionable message, huge amounts of data in a language unknown to human kind, and completely changes the entire perspective of the people of the world. All the countries of the world put aside their political differences, and for at least a few years are all completely cooperative in trying to work out the mystery of the message, and what the function of the “machine” actually is…

Probably one of the most clever narratives in science fiction that I have read or seen (to date). I don’t know much about radio telescopes and the related technologies, but with google at your side, you can definitely begin to understand more and more of how such a thing would work. I’ve learned a few things reading this book.

Thoroughly enjoyable. I recommend to anyone with even a minor interest in space.
