Book Review: Midnight's Children, by Salman Rushdie

Four stars out of Five.

One Amazon reviewer likens Midnight’s Children to a detailed tapestry with layers of characters and events and symbols. Rushdie’s creation is indeed so complicated yet delicious in it’s imagery and emotion and history.

The book is a novelized history of the nascent Indian republic after it won independence from the United Kingdom in 1947. The new nation is personified in the protagonist Saleem Sinai who was born at the stroke of midnight on August 15th, the moment of the official transfer of power. Rushdie, who was actually born earlier in the year 1947,  writes mostly in first person with the Saleem’s family and life taking on many features of his own.

As in his other fictional works, Rushdie inserts magical realism, combining supernatural powers and phenomena with real events to give a more colorful and effective treatment of history. This is similar to Kurt Vonnegut’s use of time travel and interplanetary travel in his autobiographical novel  Slaughter-House Five. Both authors promote their political opinions regarding real-world events that they had been part of or had observed.

Midnight’s Children is also a saga of war and the transformation of a nation, similar to Margaret Mitchell’s Gone With the Wind. Additionally, both works have a main character who personifies the culture-- Scarlett O’Hara, the Old South; Saleem Sinai, colonial India-- experiencing evolution as a necessary adaptation to change that they encounter in the world.

At times I found Midnight’s Children frustrating in the sheer number of symbols and thematic motifs that must be interpreted. Knowing Indian history beforehand would be helpful as well. I read as a companion text the Reader’s Guide from Continuum Contemporaries written by Norbert Schurer. He adds much value to Midnight’s Children by providing some historical context as well as pointing out much of the symbolism. Also, Sparknotes has some helpful analysis.

Salman Rushdie is a serious writer and Midnight’s Children is an award winning novel that is not for the faint of heart. Not only is it lengthy, but it contains advanced vocabulary, lots of characters, heavy themes and weird literary devices like run-on sentences and giving characters magical powers. Unlike Mitchell’s Gone With the Wind, readers of Midnight’s Children not only have to wade through history and war and a long family saga, but also supernatural symbolism, religion, social ills and enough leitmotifs to drop a pony.  

Annoyed, I had given up reading Midnight’s Children at page 100 a few years ago but finally completed the task this month. A few months ago I read Rushdie’s non-fiction memoir Joseph Anton (reviewed here), and was thus motivated to finish Midnight’s Children now in advance of the recently released movie.  Nobody will absorb all of Midnight’s Children at the first reading, but it is an impressive piece of writing.

Book Review: The Signal and the Noise, by Nate Silver

Five stars out of five.

I remember watching the TV series Quantum Leap years ago, starring Scott Bakula and Dean Stockwell who traveled through time and lived at the whim of ever-changing Bayesian probabilities. Whatever predicament they encountered has associated chance of solution or death as spit out by Stockwell’s computer named Ziggy. As the conditions changed, say, a bad guy presents himself, Stockwell would translate the changing probabilities: “Ziggy says you have a 85% chance of dying.” With a bad guy vanquished, it would change, “Ziggy now says you have only a 15% chance of dying.”

Nate Silver’s The Signal and the Noise explains the phenomenon of prior probability that subsequently changes with conditions that was first presented as Bayes Theorem three hundred years ago. Silver is a professional poker player who made his “f**k you” money by selling software to analyze baseball statistics. Recently he became a phenomenon of sorts by successfully predicting all 50 state elections in 2012 and currently writes the always informational “five-thirty-eight” blog for the New York Times.

The Signal and the Noise is a more comprehensive discussion of Bayesian probabilities and how they affect almost everything humans do. An engineer friends says that every high school kid should read Silver’s book just to get an idea of how probability works and to hone critical thinking skills. I cannot disagree.

Okay, Silver is concerned with more than the theory of Thomas Bayes, he begins by discussing the huge explosion of data available to humans beginning with the Gutenberg printing press and evolving to the electronic databases today. He also points out that humans are unduly flawed because we too often seek confirmation of our own ideas instead of critically parsing all this information. Political pundits are notorious for
stoking the confirmation biases of their customers, which has been shown by the likes of Dick Morris and Karl Rove claiming to “have the math” only to be embarrassingly wrong on the outcome of recent elections. But they aren’t embarrassed-- they aren’t paid to be correct, only to confirm bias.

Silver also uses the baseball player Dustin Pedroia as an example of the failure of Big Data. On paper, or more accurately, using computer stats, a guy like Pedroia should never have made it into Major League baseball: he’s too small, too slow, not a very powerful hitter and can’t throw very well. Instead of failing, Pedroia is an all-star and a winner. What gives? There are intangibles, data is never able to be completely known. All the stats in the world cannot always be interpreted perfectly.

Separating what’s important (the signal) from confusing interference (the noise) is the key to forecasting any natural event or human phenomenon. We are good at forecasting some things like weather and hurricanes, but poor at predicting other things like earthquakes and terror attacks. Silver is an excellent explainer of how we know things and the limitations of that knowledge. He uses a wide-ranging array of interesting stories: from bird flu and climate to Donald Rumsfeld and poker. Refreshingly, I find no ideological or political preferences in his discussion.

This book is highly recommended.
