At Columbia University, data scientist Chris Wiggins and historian Matthew Jones teach a course called Data: Past, Present and Future. Out of this collaboration has come a book, How Data Happened: A History from the Age of Reason to the Age of Algorithms, to be published on Tuesday, March 21st by W.W. Norton. It should be required reading for anyone working with data of any sort to solve problems. The book promises a sweeping history of data and its technical, political, and ethical impact on people and power.
