00:00:00,000 --> 00:00:01,170
DAVID MALAN: Hello world.

2
00:00:01,170 --> 00:00:05,590
And hello to CS50x Rasht and our friends
Aref, and Kiana, and everyone there.

3
00:00:05,590 --> 00:00:09,450
My name is David Malan, and I teach
CS50, Harvard University's introduction

4
00:00:09,450 --> 00:00:11,790
to the intellectual
enterprises of computer science

5
00:00:11,790 --> 00:00:15,030
and the art of programming for
majors and non-majors alike.

6
00:00:15,030 --> 00:00:19,380
That is to say, if you've never
programmed before, CS50 or CS50x is

7
00:00:19,380 --> 00:00:21,360
precisely the course for you now.

8
00:00:21,360 --> 00:00:24,720
By way of language is called
Scratch, and C, Python,

9
00:00:24,720 --> 00:00:28,170
and SQL, and a little bit of
JavaScript, HTML, and CSS, will

10
00:00:28,170 --> 00:00:30,520
you not only learn how to
program over the coming weeks,

11
00:00:30,520 --> 00:00:33,300
but ultimately how to create
projects of your very own.

12
00:00:33,300 --> 00:00:36,550
Indeed, the capstone experience
of this course is to do just that,

13
00:00:36,550 --> 00:00:40,140
to imagine, to design, and then
implement for the whole world to see,

14
00:00:40,140 --> 00:00:43,710
or at least your family and friends,
a project of your own choosing.

15
00:00:43,710 --> 00:00:47,820
By way of other courses that you can
take either before or after CS50 as

16
00:00:47,820 --> 00:00:49,920
well, will you learn all
the more about Python

17
00:00:49,920 --> 00:00:53,400
if you so choose by way of
CS50P, CS50's Introduction

18
00:00:53,400 --> 00:00:54,870
to Programming with Python.

19
00:00:54,870 --> 00:00:57,540
Or, especially if you're
feeling a little uncomfortable

20
00:00:57,540 --> 00:00:59,760
with the idea of putting
your toes in these waters

21
00:00:59,760 --> 00:01:03,240
and exploring computer science or
Python programming specifically,

22
00:01:03,240 --> 00:01:07,800
you might want to explore programming
by way of CS50S, CS50's Introduction

23
00:01:07,800 --> 00:01:10,740
to Programming using Scratch,
a graphical programming

24
00:01:10,740 --> 00:01:14,640
language via which you can express
your ideas by dragging and dropping

25
00:01:14,640 --> 00:01:19,120
these puzzle pieces that only interlock
if it makes logical sense to do so.

26
00:01:19,120 --> 00:01:23,410
And from there, can you then
take CS50P and/or CS50x as well.

27
00:01:23,410 --> 00:01:26,850
Ultimately, we can't wait
to see what you create

28
00:01:26,850 --> 00:01:28,950
in any of these languages or others.

29
00:01:28,950 --> 00:01:30,330
My name is David Malan.

30
00:01:30,330 --> 00:01:33,050
And this is CS50.
