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, 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 communicate 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 course, it might be useful to tell you what we aren’t going to talk about.
We aren’t going to teach you how to program.
Programming is a really crucial aspect of computer software, 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 Uno to water your plant or how to change the CSS on your grandma’s sewing blog so visitors’ cursors turn into kittens.
This also isn’t a computing course. Or at least how computing is thought of in the U.S. 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 are the history of computers… even before we had electricity.
We’re going retrace the design decisions that have given us our president-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... well 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 secondary Computing teacher, author of 'Adventures in Raspberry Pi' and the creator of a YouTube video series for teenagers called the Geek Gurl 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 inarguably have become pivotal in our society.
From our cars and thermostats to pacemakers and cellphones, 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.

Hello world!
我是Carrie Anne Philbin 欢迎来到Crash Course计算机科学！
计算机让我们可以做到很多惊艳的事情。比如国际通信、国际贸易、跨国运输、医药研究的突破。分布式教育、网购、网上约会，以及互联网的种种。
计算机允许我们探索我们自己的世界和另外的世界。当然还有一些日常生活，比如在工作的时候照看宠物，还可以用难解的颜文字跟朋友聊天。
但是不要把计算机看成是魔法。我再重复一遍，计算机不是魔法。
在我们真正进入课程内容之前，我还是说一下我们不会讲到什么。我们不会教你编程。
编程是计算机软件的重要方面，我们也会讲到引导软硬件逻辑的规则。
但我们不会教你编写一个Arduino Uno程序去给你的植物浇水。也不会教你修改你奶奶博客上的CSS，让光标看起来像只猫咪。
这也不是一门计算的课程。至少不是美国人认为的“计算”。计算是目标，而这是计算机要做的事情。
当然我们会谈到一些，但我们课程的目标要广泛的多。
“计算”在其他国家可能有其他的含义。
这可能令人混乱。
但我们会回顾计算机的历史——甚至在电的使用之前。
我们会回溯总统日元素的设计过程。
我们也会谈到操作系统如何工作，如何不工作。YouTube如何让你接触网络，智能手机和其他智能设备如何变得更智能，当然还有一些神秘未来的东西，比如量子计算，还有令人沮丧的总统日元素，比如黑客。
我们有很多要讨论的东西，但我觉得在开始之前，我要介绍一下我自己。
我叫Carrie Anne Philbin！
Hello!
我获得了计算机教师奖，《零基础学树莓派》的作者，面向青少年的YouTube系列视频“Geek Gurl Diaries”的创作者，介绍了从事计算机科学工作的女性，以及计算机科学的基础教程、还有类似数字机的项目。
在我的日常工作中，我帮助人们学习技术。作为树莓派的教育经理，我教人们电脑制作。这是一个英国剑桥的公益项目。
不用多说，我对这些非常有热情，但这并不是因为计算机一定能让我们的生活更简单。（有时也是有争议的），而是计算机定已成为我们社会中的关键部分。
无论是汽车、恒温器、心脏起搏器、手机，电脑无处不在。我希望在课程结束的时候，你能够更好地理解我们是怎么走到今天，计算机又将带我们走向何处。
