• Hello world! I'm Carrie Anne Philbin and welcome to Crash Course Computer Science.
• Computers have allowed us to do amazing things, from global telecommunications to online dating.
• We will not teach you how to program, but we will cover the history of computers and how they work.
• I'm passionate about technology and hope to help you understand its societal impact.
• Join me next week as we explore the world of computer science together!

Hello world. I'm Carrie Anne Philbin and welcome to Crash Course Computer Science.

So computers really have allowed us to do some pretty amazing things. Think global telecommunications, international commerce, global transportation, breakthroughs in medicine, distributed education, online shopping, online dating, and just the Internet in general.

Computers are allowing us to explore our own world and other worlds, and of course, some seemingly mundane things like permitting us to spy on our pets from work or commute, communicating with our friends in a nearly indecipherable stream of emoji.

But don't call computers magical. They are not, I repeat, are not magical.

So before we get into what we are going to talk about in this series, it might be useful to tell you what we are not going to talk about. We aren't going to teach you how to program. Programming is a really crucial aspect of computer science. And we will get to the rules that guide the logic of hardware and software design. But we aren't going to teach you how to program an Arduino to water your plant or how to change the CSS on your grandma's sewing blog.

So visitors curses turn into kittens.

This also isn't a computing, or at least how computing is thought of in the US. Computing here is a goal. It's what computers do. And we'll talk about some of that for sure. But our goal for this course is much broader. But computing means other things in other countries; it's all pretty confusing.

But what we are going to look at are the history of computers, even before we had electricity. We're going to retrace the design decisions that have given us our present day components.

We're going to talk about how operating systems work or don't work, how the YouTubes get to you over the Internet, how our smartphones and other smart devices are or getting smarter, and of course mysterious futuristic stuff like quantum computing and frustrating present day stuff like hacking.

It's a lot to cover. But I suppose before we get started I should introduce myself.

I'm Carrie Anne Philbin. Hello. I'm an award winning computing teacher, author of Adventures in Raspberry PI and the creator of a YouTube video series for teenagers called the Geek Girl Diaries, which includes stuff like interviews with women working in technology, computer science-based tutorials, and hands-on digital maker style projects.

In my day job, I help people learn about technology and how to make things with computers as Director of Education for the Raspberry PI foundation, which is a charity based in Cambridge in the UK.

Needless to say, I am passionate about this stuff. But not because computers are these amazing devices that are always making our lives easier. Sometimes that's debatable, but because computers in Argobee have become pivotal in our society, from our cars and thermostats to pacemakers and cell phones, computers are everywhere.

And it's my hope that by the end of this course, you'll have a better understanding and appreciation for how far we've come and how far they may take us.

I'll see you next week.
