Review: Blue Remembered Earth by Alastair Reynolds

Blue Remembered Earth (Poseidon's Children, #1)Blue Remembered Earth by Alastair Reynolds
My rating: 4 of 5 stars

“Blue Remembered Earth” is the first of a new series, Poseidon’s Children, by Alastair Reynolds. Unlike his previous work in the Revelation Space series, this book is set in the Solar System. The main events of the book happen in the mid 22nd century as imagined by Mr. Reynolds. The book is also a departure in style from his previous work. It is lighter and more optimistic than any of the books in the Revelation Space series. The work is more character driven and has fewer information dense “hard science” passages.

Surprisingly, it also does not revolve around a “chase sequence” that a lot of Mr. Reynold’s work seem to have as a central plot point ( See The House of Suns, or the short story Galactic North). I think the book is better for it.

Blue Remembered Earth is more character driven and has a lot less action than previous books by Mr. Reynolds, but remains an engrossing and rewarding read. The books centres around Geoffrey and Sunday Akinya, siblings and members of the powerful Akinya clan. It starts with the funeral of Eunice Akinya, the reclusive scion of the clan and picks up space as Geoffrey and Sunday are involved in the attempt to disentangle some of the mysteries of their late grandmother. The book takes us to the Moon, to Mars and beyond.

The plot moves along at fair pace, but it is clear that the author is just setting the things for bigger things to come in subsequent books. The future as described here is believable and the science is very plausible. I particularly enjoyed the chapters following Sunday Akinya’s adventures on Mars.

If you came to this book expecting some of the Gothic feel and the dystopian futures seen in Absolution Gap or Chasm City, you may be disappointed. I enjoyed this lighter style and look forward to future installments in this series.

Review: Complexity: A Guided Tour by Melanie Mitchell

Complexity: A Guided TourComplexity: A Guided Tour by Melanie Mitchell
My rating: 4 of 5 stars

How does an ant colony organize itself? How does the immune system work? What is the similarity between the world wide web and your brain?

If you have pondered any of these questions, “Complexity: A Guided Tour” is just the book for you.1

Any computer scientist who graduated in the last ten or so years would have covered some of the topics in Melanie Mitchell’s “Complexity: A Guided Tour”, and would have probably wished that they had Ms. Mitchell as a lecturer!

Ms. Mitchell is clearly passionate about her subject. Her book covers a number of topics in the emerging field of Complexity such as emergent behaviour, computer science, genetic algorithms, network theory, etc. Ms. Mitchell does not get too technical, but still manages to convey the key ideas with clarity. Her explanation of Turing’s universal computer and the “Halting Problem” are great examples of explaining a complex topic in an approachable manner. I enjoyed the chapters on genetic algorithms, computability and cellular automata. I wish she had gone into a bit more detail on Network theory.

This is an enjoyable book for anyone who is interested in computer science or is mathematically inclined. Those without a background in computer science may find it a bit of a slog. Ms. Mitchell also provides generous notes and references for further study. I enjoyed this book very much.

Review: A Deepness in the Sky by Vernor Vinge

A Deepness in the Sky (Zones of Thought, #2)A Deepness in the Sky by Vernor Vinge
My rating: 4 of 5 stars

“A Deepness in the Sky” is a Big Book. The plot unfolds via the point of view of multiple characters, both human and the “Spider” aliens. The story centers around the planet Arachna which attracts the interest of two competing human fleets due to the strange nature of the star in the system – the “On/Off” star which comes to life every 200 odd years and stays bright for a few decade before dimming again.

There are two main strands to the story. One based at the Lagrange point above the planet, and one on the planet itself as a new “On” cycle starts. The story is based over a number of years as the Arachnid civilization moves up the technological ladder. The story telling, especially in the human segments conveys a sense of claustrophobia and foreboding that contrasts nicely with the more open story arcs that play out planet side.

Mr. Vinge explores the concepts of freedom, religion and progress in this book. The science is plausible (no FTL) and the universe is believable. While the story can get bogged down in places as it explores the motivations and background of its multiple characters, it still remains extremely enjoyable read for any fan of science fiction.

Review: The Fear Index by Robert Harris

 

The Fear Index is a breezy, fun read. Clearly the author has done his research on the financial markets and the world of hedge funds. Even the basic idea behind the protagonist’s hedge fund is feasible.  Sentiment analysis is a hot topic in machine learning, and I think there are already commercial products available that will analyse the sentiment for a given stream of data.

The story focuses on a day in the life of Alex Hoffman – Super Quant.  It starts with a break-in in the dead of the night and, like all good thrillers ends with a big bang.  Hoffman’s business partner, his wife and the befuddled policeman Leclerc are little more than the scaffolding to the rest of the plot. While the story moves along at a fair clip, and it is hard to put down, I did not find the characters that interesting. I suppose it is difficult to empathize with socially awkward billionaires having a bad hair day.

Where the book disappointed me was the plot. The HAL 9000 \ AI elements of the story are weak and similar stories have been covered a lot better, for example, by Charles Stross in Rule 54 or Accelerando. If you are looking for a fun thriller, I heartily recommend The Fear Index. If you are a fan of science fiction, you might want to steer clear.
