DAVID MALAN: Hello world,
and hello to CS50x Latvia.

2
00:00:03,060 --> 00:00:05,640
My name is David Malan, and
I'm here at Harvard University

3
00:00:05,640 --> 00:00:07,320
where I teach Computer Science 50.

4
00:00:07,320 --> 00:00:10,140
Otherwise known as CS50, which
is Harvard's introduction

5
00:00:10,140 --> 00:00:12,270
to the intellectual
enterprises of computer science

6
00:00:12,270 --> 00:00:13,800
and the art of programming.

7
00:00:13,800 --> 00:00:16,110
In this course, you'll learn
not only how to program,

8
00:00:16,110 --> 00:00:18,162
but also how to build
projects of your very own.

9
00:00:18,162 --> 00:00:20,370
We'll begin in the course
with a programming language

10
00:00:20,370 --> 00:00:22,650
called Scratch, by which
you'll drag and drop

11
00:00:22,650 --> 00:00:26,190
these puzzle pieces via which
to express yourself logically.

12
00:00:26,190 --> 00:00:28,110
We'll then transition
to a more traditional,

13
00:00:28,110 --> 00:00:31,770
older language called C via which
you'll learn how to program textually

14
00:00:31,770 --> 00:00:33,040
using only your keyboard.

15
00:00:33,040 --> 00:00:35,910
But with C will you understand
the underlying principles

16
00:00:35,910 --> 00:00:38,250
behind all of today's modern languages.

17
00:00:38,250 --> 00:00:40,110
Thereafter, we'll transition to Python.

18
00:00:40,110 --> 00:00:42,510
A more modern, higher
level language via which

19
00:00:42,510 --> 00:00:44,790
you'll be able to create
web applications and more.

20
00:00:44,790 --> 00:00:47,582
And toward the end of the semester
we'll introduce you to databases

21
00:00:47,582 --> 00:00:49,530
by way of a language
called SQL and the web

22
00:00:49,530 --> 00:00:52,320
itself by way of HTML,
JavaScript, and CSS.

23
00:00:52,320 --> 00:00:54,360
And ultimately, the
capstone of the course

24
00:00:54,360 --> 00:00:56,940
will be to create your
very own final project.

25
00:00:56,940 --> 00:01:00,540
Indeed, we cannot wait to see what
you create over the coming months

26
00:01:00,540 --> 00:01:03,500
because this is CS50.

27
00:01:03,500 --> 00:01:04,000
