JOHN DOLHUN: You got the sock?

3
00:00:02,460 --> 00:00:03,960
OK.

4
00:00:03,960 --> 00:00:07,660
So I'm just going to put
the sock in here.

5
00:00:07,660 --> 00:00:08,770
He's going to catch it.

There it goes.

8
00:00:13,440 --> 00:00:15,200
Let's check his sock out.

9
00:00:15,200 --> 00:00:17,308
Is it still OK?

NARRATOR: It's day one.

12
00:00:57,260 --> 00:01:00,440
MIT instructor John Dolhun
introduces the course.

13
00:01:00,440 --> 00:01:03,640
JOHN DOLHUN: You're going to
learn basic skills that will

14
00:01:03,640 --> 00:01:08,350
form building blocks in your
future adventures at MIT and

15
00:01:08,350 --> 00:01:09,890
outside of MIT.

16
00:01:09,890 --> 00:01:13,250
NARRATOR: That is,
if you pass.

17
00:01:13,250 --> 00:01:15,220
And what exactly
does that take?

18
00:01:15,220 --> 00:01:18,500
JOHN DOLHUN: You're going to get
about 14 hours of lecture,

19
00:01:18,500 --> 00:01:21,630
about 52 to 75 hours of lab.

20
00:01:21,630 --> 00:01:25,460
We only have two and
a half weeks.

21
00:01:25,460 --> 00:01:30,230
You have to be able to think out
of the box, be creative,

22
00:01:30,230 --> 00:01:34,720
and most importantly, be mindful
of your mistakes.

23
00:01:34,720 --> 00:01:36,090
PHIL: The hoods are
over there...

24
00:01:36,090 --> 00:01:38,290
NARRATOR: Next, safety
training.

25
00:01:38,290 --> 00:01:41,030
Remember, for many of the
students this is their first

26
00:01:41,030 --> 00:01:42,200
time in the lab.

27
00:01:42,200 --> 00:01:46,610
No flip-flops, no shorts, no
skirts, but most importantly,

28
00:01:46,610 --> 00:01:48,760
gloves and goggles starting
tomorrow.

29
00:01:48,760 --> 00:01:51,190
PHIL: They tell you to wear
goggles and everything.

30
00:01:51,190 --> 00:01:53,460
And you don't really realize the
importance until you have

31
00:01:53,460 --> 00:01:55,830
a piece of glass flying
at your face.

32
00:01:55,830 --> 00:01:58,690
NARRATOR: After four hours of
lecture, the students finally

33
00:01:58,690 --> 00:01:59,780
check into the lab.

00:01:59,780 --> 00:02:01,140
TENGFEI: My name is Tengfei.

35
00:02:01,140 --> 00:02:03,680

36
00:02:03,680 --> 00:02:06,900
And we will be the TAs
for this class.

should have in your drawer and

00:02:22,372 --> 00:02:23,530
Nevermind.

00:02:23,530 --> 00:02:26,050
ETHAN: I guess I get the antique
shelf or something.

43
00:02:26,050 --> 00:02:28,480
But we'll work around it.

44
00:02:28,480 --> 00:02:33,340

45
00:02:33,340 --> 00:02:35,930
NARRATOR: After checking in, the
students get introduced to

46
00:02:35,930 --> 00:02:37,670
a technique called
nuclear magnetic

47
00:02:37,670 --> 00:02:40,860
resonance, or NMR for short.

48
00:02:40,860 --> 00:02:44,810
NMR helps chemists piece
together a molecule structure.

49
00:02:44,810 --> 00:02:48,390
The students put their mystery
molecule into a thin tube and

50
00:02:48,390 --> 00:02:51,810
lower it into a very powerful
magnetic field.

51
00:02:51,810 --> 00:02:55,130
This forces certain atoms in the
sample to align themselves

52
00:02:55,130 --> 00:02:57,930
either with or against
the field.

53
00:02:57,930 --> 00:03:00,440
Aligning with the field
takes less energy.

54
00:03:00,440 --> 00:03:02,810
So there are a few more
atoms aligned with

55
00:03:02,810 --> 00:03:04,870
than against the field.

56
00:03:04,870 --> 00:03:07,580
A pulse of energy makes the
extra atoms aligned with the

57
00:03:07,580 --> 00:03:09,290
field flip.

58
00:03:09,290 --> 00:03:12,470
The computer measures how much
energy this takes and produces

59
00:03:12,470 --> 00:03:13,970
a spectrum.

60
00:03:13,970 --> 00:03:17,280
The amount of energy it takes
to flip an atom depends on

61
00:03:17,280 --> 00:03:19,350
what other atoms
are next to it.

62
00:03:19,350 --> 00:03:22,890
That means you can tell which of
the atoms are connected and

63
00:03:22,890 --> 00:03:26,460
put together a picture of what
the whole molecule looks like.

64
00:03:26,460 --> 00:03:27,890
That's the theory.

65
00:03:27,890 --> 00:03:30,290
But the students are about to
learn that dealing with a real

66
00:03:30,290 --> 00:03:33,160
live machine is not so simple.

67
00:03:33,160 --> 00:03:34,447
ANNE RACHUPKA: Awful lot
we're going to go over.

68
00:03:34,447 --> 00:03:36,395
These are live magnets.

69
00:03:36,395 --> 00:03:38,343
They are in field
at all times.

70
00:03:38,343 --> 00:03:43,213
You cannot go anywhere near it
with iPod, iPhone, any USB

71
00:03:43,213 --> 00:03:47,109
storage devices, no push pins,
no staples, no bobby pins.

72
00:03:47,109 --> 00:03:49,070
We have our little sample?

73
00:03:49,070 --> 00:03:51,740
I have taken people to the
hospital because they've put

74
00:03:51,740 --> 00:03:53,500
an NMR tube through
their hand.

75
00:03:53,500 --> 00:03:56,380
Definitely don't bring your
wallet anywhere near the

76
00:03:56,380 --> 00:03:56,860
instrument.

77
00:03:56,860 --> 00:04:00,230
This costs probably more than
one year tuition to MIT.

78
00:04:00,230 --> 00:04:02,230
Obviously, this is not
going to work.

79
00:04:02,230 --> 00:04:05,410
Do not, under any circumstances,
insert your

80
00:04:05,410 --> 00:04:07,750
sample without the air on.

81
00:04:07,750 --> 00:04:09,430
You guys have any burning
questions?

82
00:04:09,430 --> 00:04:11,610
You're all going to be experts

84
00:04:11,940 --> 00:04:12,660

about this anymore?

NARRATOR: The day
is finally over.

90
00:04:22,720 --> 00:04:26,140
And it's time to head home.

91
00:04:26,140 --> 00:04:28,400
IKE: It was pretty intimidating
because I walked

92
00:04:28,400 --> 00:04:30,440
into this class with all
these smart people.

93
00:04:30,440 --> 00:04:32,410
ETHAN: I felt, I guess, a
little bit overwhelmed.

94
00:04:32,410 --> 00:04:36,430
I wasn't exactly sure what
to expect from 5.301.

EMILY: I didn't expect it
to be this much work.

96
00:04:39,096 --> 00:04:42,470
I'm kind of doubting whether I
made the right choice to take

97
00:04:42,470 --> 00:04:43,370
this class.

have I gotten into ?
