 All right, so today I'm going to be talking about a brief history of data analytics. And really, you can tell a brief history of data analytics if you don't know about data. So really, this can be said to be a brief history of data itself, not just data analytics. So where did we start getting data? The earliest example we have of human storing and analyzing data are the talistics. The Ishango bone was discovered in 1960 in what is now Uganda. And it's thought to be one of the earliest pieces of evidence of prehistoric data storage. Now, Paleolithic period or Paleolithic tribes, tribe people used to mark notches into sticks and bones to keep track of trading activities or supplies. They would compare these sticks and then they would know, OK, is our harvest going to be, do I have enough supplies or stuff like that? But really, the first calculator in the world was the abacus, the first dedicated device constructed specifically to perform calculations. And this was in Babylon, the first libraries where the first libraries kind of occurred. But the abacus, really, in modern times, most people don't know how to use it. But there are special breed of people in Japan that actually use the abacus for mental arithmetic, kind of polishes their mental or kind of critical thinking skills. Let me just show you something. Just watch this. Thank you. 9348, 4946, 1377, 450. Thank you. Thank you. So moving on from the historic times, let's talk about emergence of statistics. And here we have talked about a fellow called John Grunt in 1963, invented or first recorded experiment of statistic data analysis, recorded information about mortality. Then we'll move to 1865. The term business intelligence is used for the first time by Richard Miller Stevens in his encyclopedia of commercial and business anecdotes. However, he didn't mention business intelligence to refer to BI technology that is being used today. What he did was Devons used it to describe Sir Henry Fornes' strategy to make profit. So Sir Henry Fornes, a banker, was able to gain advantage over his competitors by collecting studying data, or acting on data that he collected. But really, when we also want to talk about the early days of modern data storage, we need to talk about Nikola Tesla. Now Tesla is known for other things, but Nikola Tesla states that in an interview that when wireless technology is perfected or perfectly applied to the whole earth will be converted into a huge brain, which in fact it is. All things being particles of a real and rhythmic whole. That seems to be kind of interesting. But he said that the telephone we know today and in the future is going to be as small as being able to put in your pocket. That's what in 1926 he made that prediction. In 1928 Fritz Pulmer, a German Austrian engineer, invented a method for storing information magnetically on tape. The principle he developed is still used today with a vast majority of digital data being stored magnetically on computer hard disks. Now unfortunately, this is where I stop on my presentation and the whole story will continue up to today. But yeah, this is just these 12 slides. So thank you very much guys for listening to the abridged version. And what do you think?
