TAL SCULLY: Advice
for students, I

2
00:00:07,780 --> 00:00:11,230
would say that the most
important thing for this class

3
00:00:11,230 --> 00:00:15,010
is knowing that
things will go wrong,

4
00:00:15,010 --> 00:00:19,720
but that you can work through
it and things will often

5
00:00:19,720 --> 00:00:21,970
resolve themselves.

6
00:00:21,970 --> 00:00:24,550
Certainly for one experiment
we were working on,

7
00:00:24,550 --> 00:00:29,180
for the Spring Break
onion experiment,

8
00:00:29,180 --> 00:00:30,670
the numbers weren't working out.

9
00:00:30,670 --> 00:00:33,310
And after about
30 hours of work,

10
00:00:33,310 --> 00:00:35,354
I finally found this
one trivial error

11
00:00:35,354 --> 00:00:36,520
I had made at the beginning.

12
00:00:36,520 --> 00:00:39,080
And everything
started working out.

13
00:00:39,080 --> 00:00:41,170
And it was just
putting in the hours

14
00:00:41,170 --> 00:00:43,360
and knowing there's
something there.

15
00:00:43,360 --> 00:00:45,680
You just have to keep
persisting through it.

16
00:00:45,680 --> 00:00:48,280
And it's not an easy
thing to learn to do,

17
00:00:48,280 --> 00:00:50,487
but it's very important.
