A documentary on algorithms and their practical uses in our lives, presented by Oxford mathematics Professor Marcus du Sautoy.

Interesting and edifying. Professor du Sautoy, who also brought us the documentary series The Story of Maths, takes a very complex subject and makes it understandable and relatable. By taking everyday examples, e.g. the ordering of planes taking off at Heathrow, du Sautoy demonstrates the uses, importance and abundance of algorithms.

The downside to making it more widely accessible and understandable is that the documentary is quite light on the maths. As a mathematical person I would have preferred a bit more of the technical side of such algorithms. Can't have it both ways, I suppose.

The other negative of the program is that, by his own admission, Professor du Sautoy doesn't like This Is Spinal Tap...

Here's the irony -- I ended up watching this fascinating documentary on algorithms *because* of Netflix's (extremely accurate) recommendation algorithm.

As someone who works with algorithms in the field, I found this documentary to be a super enjoyable watch. This documentary, in my opinion, will especially be a good watch for those curious about the BIG world of algorithms, especially given the fact that the documentary neatly explains many of the most widely used algorithms in real life and shows how it's entrenched in nearly every part of our modern lives. This should also be a good watch for young children to get them curious about algorithms and computer science in general.

Marcus du Sautoy, a mathematician at heart, guides us, in an easy manner, through the power and complexity of this ambiguous things called algorithms, that rule and shape our world every single day. It's very interesting to see the various types they come in, and much more interesting, rather astonishing, to see them in action. Whether your searching the internet or taking a photo, high chances are algorithms are running in the background. I invite you to watch this compelling documentary, to gain a slight insight of how algorithms work.
