Hello World!

[MUSIC] 0:00 Hello, world. 0:09 My name is Richard, I'm an instructor at Treehouse, 0:10 and my background is computer science. 0:13 Your first question might be, what exactly is computer science? 0:16 Is it the science of working with computers? 0:20 Well, there's no set definition. 0:23 It seems that every major university and 0:26 computing organization has their own take on it. 0:28 To help us define computer science, 0:32 consider the Oscar nominated film Hidden Figures released in 2016. 0:35 It was the true story of Black women who are hired at NASA to perform complex 0:40 mathematical calculations for upcoming space missions. 0:45 Their job title, computers. 0:49 So the term computer science doesn't necessarily refer to this machine we call 0:53 a computer, because the term existed long before computers were widely available. 0:58 In fact, Edsger Dijkstra, 1:03 an influential figure in the early days of the discipline, once stated that computer 1:05 science is no more about computers than astronomy is about telescopes. 1:10 It has been argued that a more appropriate term might be computing science, 1:17 although most of the work in the modern age is done for and by computers. 1:22 So here's our definition. 1:29 Computer science is the study and design of algorithms, 1:31 computations, and information systems, in both theory and 1:35 practice, typically with the aid of computers. 1:40 I know, that's a mouthful. 1:45 As we move forward, we will provide more 1:47 understanding of the term computer science as you begin this new journey. 1:50 Just like telescopes are tools in the study of astronomy, 1:55 computers are tools in computer science. 1:59 In the next video, we will unpack the history of computers and the Internet. 2:03 See you there. 2:08
