Big Data by Viktor Mayer-Schönberger & Kenneth Cukier Summary
Overview of Big Data
"Big Data" reveals how massive datasets are revolutionizing everything from flu prediction to crime prevention. Featured on the US Air Force's reading list, Oxford professor Mayer-Schonberger shows why correlation now trumps causation. Could your digital footprint predict your next purchase - or disease?

The Data Revolution That's Reshaping Our World
When Google tracked the 2009 H1N1 flu pandemic faster than the CDC by analyzing search queries, it signaled a fundamental shift in how we understand reality. This wasn't just clever technology-it was the dawn of the Big Data era. For most of human history, we've been forced to work with limited information. The 1880 U.S. census required eight years to process, making its insights obsolete before publication. These weren't just logistical problems but fundamental constraints on human knowledge. Today, those constraints have shattered. With billions of sensors, smartphones, and connected devices generating continuous data streams, we can analyze entire datasets rather than mere samples. Consider how Xoom, a financial services company, detected fraud by analyzing all transactions rather than investigating suspicious samples. They discovered subtle patterns that would have remained invisible using traditional approaches. This shift from sampling to comprehensive analysis fundamentally changes what we can know. Economist Steven Levitt's examination of 64,000 sumo wrestling matches revealed match-fixing patterns that would have been undetectable through sampling. Similarly, network analysis of millions of mobile phone connections showed that peripheral members with outside connections are more crucial to network stability than well-connected central figures-a counterintuitive finding that traditional methods would have missed. What makes this revolution particularly fascinating is its prescience. Written before terms like "data science" became household phrases, Big Data accurately predicted how information would transform everything from healthcare to criminal justice, fundamentally changing our relationship with information and decision-making.
