      Exponential Increase in Data
 • All human generated information up 
  to 2003 was about 5 exabytes. 
 • Same amount of data was generated

 • and would be every 10 min NOW.
   “Data is the New Oil” 
  – World Economic Forum 
          2011
  • “Data is the new oil." Coined in 2006 by 
   Clive Huby, a British data 
   commercialization entrepreneur, this 
   now famous phrase was embraced by 
   the World Economic Forum in a 2011 
   report,
  • Data is just like crude oil. It’s valuable, 
   but if unrefined it cannot really be 
   used. It has to be changed into gas, 
   plastic, chemicals, etc. 
  • To create a valuable entity that drives 
   profitable activity; so must data be 
   broken down, analyzed for it to have 
   value.
           What is Data Science? 
    • Fortune magazine  
      • “Hot New Gig in Tech” 
    • Hal Varian, Google’s Chief Economist, NYT, 2009:  
      • Statistics: The next attractive job 
      • “The ability to take data—to be able to understand it, to process it, to extract value 
      from it, to visualize it, to communicate it—that’s going to be a hugely important skill.” 
    • Mike Driscoll, CEO of meta markets:  
      • “Data science, as it's practiced, is a blend of Red-Bull-fueled hacking and espresso-
      inspired statistics.” 
      • “Data science is the civil engineering of data.  Its acolytes possess a practical knowledge 
      of tools & materials, coupled with a theoretical understanding of what's possible.”
