Do human emotions have a role to play in science and research? Material researcher Ilona Stengel suggests that instead of opposing each other, emotions and logic complement and reinforce each other. She shares a case study on how properly using emotions (like the empowering feeling of being dedicated to something meaningful) can boost teamwork and personal development -- and catalyze scientific breakthroughs and innovation.

I'm a scientist,
0
752
2176
00:14
and I'm a big fan of Star Trek,
1
2952
3088
00:18
especially of Mr. Spock.
2
6064
2476
00:21
Mr. Spock is a scientist as well,
3
9781
2026
00:23
and at the same time,
he's the first [officer]
he's the first [officer]

2157
00:26
of the starship Enterprise,
5
14012
2968
00:29
and during the adventures
of the Enterprise crew,
of the Enterprise crew,
6
17004
3120
00:32
he and his colleagues are dealing a lot
7
20148
2126
00:34
with the presence or absence
of Mr. Spock's emotions.
of Mr. Spock's emotions.
8
22298
4642
00:39
Mr. Spock is half-human and half-Vulcan,
9
27924
3707
00:43
and Vulcans are an alien race
10
31655
2658
00:46
who learn to control
and suppress their feelings
and suppress their feelings
11
34337
2715
00:49
and to act purely out of logic.
12
37076
2014
00:51
As Mr. Spock is only half-Vulcan,
13
39995
2715
00:54
he sees himself constantly in conflict
in between logic and emotions,
in between logic and emotions,
14
42734
5557
01:00
and as he's part of a team,
15
48315
2024
01:02
the whole crew is struggling with,
16
50363
2880
01:05
is analyzing,
17
53267
1771
01:07
and is making fun of this conflict.
18
55062
1825
01:09
And also the fans of Star Trek
watch with amusement
watch with amusement
19
57566
2907
01:12
this seemingly contradictory behavior.
20
60497
2231
01:15
They find it quite fascinating.
21
63155
3113
01:19
And the matter is a golden thread
22
67362
1666
01:21
through the whole Star Trek series
and movies from the '60s until today.
and movies from the '60s until today.
23
69052
3663
01:25
And that's actually
what I want to talk about today:
what I want to talk about today:
24
73091
2825
01:27
the role of emotions in science.
25
75940
2326
01:31
We tend to think that science
is all about facts and logic
is all about facts and logic
26
79353
4343
01:35
and human feelings are often neglected
or considered an obstacle to get rid of.
or considered an obstacle to get rid of.
27
83720
4309
01:40
I would like to suggest that emotions
are as important in science
are as important in science
28
88989
4311
01:45
as they are in any other part
of our lives.
of our lives.
29
93324
2261
01:48
Science is made by humans,
30
96195
2183
01:50
and as human beings,
31
98402
1705
01:52
even if we try hard,
we cannot get rid of our emotions.
we cannot get rid of our emotions.
32
100131
3814
01:56
So instead of fighting them,
33
104704
2179
01:58
I believe that even in science,
we should make use of our feelings,
we should make use of our feelings,
34
106907
3548
02:02
because for breakthroughs and innovation,
35
110479
2206
02:04
they are equally important
as facts and logic.
as facts and logic.
36
112709
2611
02:09
I will come back to Mr. Spock,
37
117256
1960
02:11
but first let me share my experience
on the role of emotions and science,
on the role of emotions and science,
38
119240
5152
02:16
and one story in particular
kept me thinking about it
kept me thinking about it
39
124416
2889
02:19
for the last couple of years.
40
127329
1697
02:21
I'm working in research
on organic light-emitting diodes,
on organic light-emitting diodes,
41
129940
4255
02:26
so-called OLEDs.
42
134219
1523
02:28
This is how you might know them,
43
136233
2005
02:30
as new generation of displays.
44
138262
2254
02:33
OLEDs are more and more used
in smartphone displays and TV screens.
in smartphone displays and TV screens.
45
141262
4325
02:37
They make them appear bright,
truly colorful and bendable.
truly colorful and bendable.
46
145611
4707
02:43
This is how they look like
47
151963
1251
02:45
in the research lab
of my physicist colleagues.
of my physicist colleagues.
48
153238
2608
02:48
And this is what I, as a chemist,
49
156979
2191
02:51
have in mind when I think about them.
50
159194
2444
02:53
I've loved it ever since
I started to work on it.
I started to work on it.
51
161662
2865
02:57
So I didn't really like the news
52
165415
2196
02:59
when the company I had been working for --
53
167635
2318
03:01
that was my previous employer --
54
169977
2202
03:04
announced that they wanted
to stop OLED research.
to stop OLED research.
55
172203
2801
03:08
At the time, the management
had reasons for this decision,
had reasons for this decision,
56
176159
2931
03:11
and the company handled it
very well, actually.
very well, actually.
57
179114
2418
03:13
Nobody lost their jobs,
58
181556
1780
03:15
and everybody was rewarded
for their performed work.
for their performed work.
59
183360
2746
03:19
What I want to show you today
60
187043
1414
03:20
is what happened
with my scientist colleagues and me
with my scientist colleagues and me
61
188481
2922
03:23
during the time in between
the announcement
the announcement
62
191427
2737
03:26
and the last working day on our project.
63
194188
2278
03:29
Consider it a small case study
on emotions in science.
on emotions in science.
64
197067
3849
03:34
In 2015, our research team
had grown to more than 80 people,
had grown to more than 80 people,
65
202454
4777
03:39
and even after the announcement
that our project was discontinued,
that our project was discontinued,
66
207255
3469
03:42
we could not stop working
from one day to another.
from one day to another.
67
210748
2488
03:45
It took several months
to bring all activities to a sound end
to bring all activities to a sound end
68
213759
3931
03:49
and to find new jobs
within the company for everyone.
within the company for everyone.
69
217714
2888
03:53
Here's what happened.
70
221088
1333
03:54
Even though we knew
that we were working on a project
that we were working on a project
71
222445
2647
03:57
that was to be stopped,
72
225116
1996
03:59
during those months
our output hit the roof.
our output hit the roof.
73
227136
3082
04:03
We were actually working
on two different OLED projects:
on two different OLED projects:
74
231377
3380
04:06
first, the development of materials
for blue-shining OLEDs,
for blue-shining OLEDs,
75
234781
3993
04:10
which had started in 2001;
76
238798
2636
04:13
and second, materials for green OLEDs,
which had started in 2014.
which had started in 2014.
77
241458
5673
04:19
And the results I show you here
concern the green OLED project.
concern the green OLED project.
78
247155
3317
04:23
In the graph, you can see
how the lifetime,
how the lifetime,
79
251297
2732
04:26
which is a crucial measure
for the durability of our devices,
for the durability of our devices,
80
254053
3787
04:29
developed over time.
81
257864
1657
04:32
In 2015, just half a year
into the project,
into the project,
82
260677
4071
04:36
we were told to scale down,
83
264772
2406
04:39
to stop working on the project
as soon as possible
as soon as possible
84
267202
3175
04:42
and to start over in other jobs.
85
270401
1793
04:44
Nevertheless, from this time on,
86
272987
2541
04:47
our results continued to improve rapidly.
87
275552
3003
04:52
How did that happen?
88
280097
1150
04:55
After the announcement, pretty quickly,
colleagues started leaving the team,
colleagues started leaving the team,
89
283070
4263
04:59
and soon, we were left in a small group,
90
287357
2436
05:01
all pretty much sharing
the same attitude of,
the same attitude of,
91
289817
3044
05:04
"I'm going to be the last person
leaving the ship."
leaving the ship."
92
292885
2563
05:08
What I mean is,
93
296410
1472
05:09
while the number of scientists
working on the project was decreasing,
working on the project was decreasing,
94
297906
4029
05:13
the dedication of people remaining
grew dramatically.
grew dramatically.
95
301959
3683
05:19
And also, a new and more intense
team spirit formed.
team spirit formed.
96
307054
3580
05:23
We all shared the same
passion for our work,
passion for our work,
97
311543
3227
05:26
we all were sad that it was about to end,
98
314794
3277
05:30
and we all wanted to show
that we could turn our ideas into reality.
that we could turn our ideas into reality.
99
318095
3770
05:34
We felt that we belonged
to something bigger.
to something bigger.
100
322647
2841
05:38
And furthermore,
101
326790
1579
05:40
our project was less and less
in the focus of the management,
in the focus of the management,
102
328393
3692
05:44
because they started
to think about new projects,
to think about new projects,
103
332109
2707
05:46
restructuring and so on.
104
334840
1697
05:49
This resulted in additional freedom
105
337434
2723
05:52
and the possibility to take
a few things into our own hands.
a few things into our own hands.
106
340181
4022
05:57
Of course, more freedom
also means more responsibility,
also means more responsibility,
107
345001
4746
06:01
which we were happy to take,
because we believed in our work.
because we believed in our work.
108
349771
3866
06:05
We felt empowered.
109
353989
1672
06:08
And these three pillars --
110
356589
1796
06:10
dedication, belonging and empowerment --
111
358409
4828
06:15
worked together in a kind
of self-reinforcing cycle,
of self-reinforcing cycle,
112
363261
3445
06:18
and the closer we got to shutdown,
113
366730
2149
06:20
the better our output became.
114
368903
1659
06:23
So we were working
with such personal engagement
with such personal engagement
115
371241
2556
06:25
on a project already sentenced to death
116
373821
2286
06:28
because we felt connected
to something meaningful.
to something meaningful.
117
376131
3400
06:33
Of course, it was also a hard
and sometimes frustrating time,
and sometimes frustrating time,
118
381440
4961
06:38
but we were sitting together in the lab,
119
386425
2016
06:40
or occasionally in the café,
120
388465
2080
06:42
sharing our sadness
about the end of our project
about the end of our project
121
390569
3357
06:45
as well as the joy in our work.
122
393950
2531
06:48
So overall, we had a very intense
and mesmerizingly exciting time.
and mesmerizingly exciting time.
123
396505
5449
06:54
And the lifetime we finally obtained
for our materials
for our materials
124
402466
3904
06:58
was on one level with already
commercialized materials
commercialized materials
125
406394
3539
07:01
for green OLEDs at the time,
126
409957
2117
07:04
and we achieved this within just one year.
127
412098
2539
07:07
And those results helped our employer
128
415431
3048
07:10
to sell the patents for real value.
129
418503
2293
07:14
Now, let me tell you the same story
130
422923
3186
07:18
with different characters
and a slightly different operation.
and a slightly different operation.
131
426133
3723
07:22
The story is part of Star Trek.
132
430341
1710
07:24
And sorry for those of you
who haven't seen the movies,
who haven't seen the movies,
133
432602
2613
07:27
but I need to introduce a spoiler here.
134
435239
1966
07:30
After Mr. Spock sacrificed himself
to save the starship Enterprise
to save the starship Enterprise
135
438643
4688
07:35
at the end of Star Trek II,
136
443355
2300
07:37
Captain Kirk and his core team
137
445679
1567
07:39
were determined to hunt
through the universe to search for Spock,
through the universe to search for Spock,
138
447270
4203
07:43
even though they could see
only very little chance
only very little chance
139
451497
2584
07:46
in finding him alive.
140
454105
1399
07:48
And Starfleet Command
did not give them permission
did not give them permission
141
456393
2801
07:51
nor a starship to do so,
142
459218
2109
07:53
so they took it very passionately
into their own hands
into their own hands
143
461351
3421
07:56
to travel out to find Spock.
144
464796
1888
07:59
And after dealing with great challenges,
they eventually found Spock,
they eventually found Spock,
145
467657
3918
08:03
and he happily and gratefully
joined the team again.
joined the team again.
146
471599
3334
08:08
He could feel the dedication
and the connection of his team
and the connection of his team
147
476235
3548
08:11
towards their project,
which was to save him
which was to save him
148
479807
3444
08:15
and to hold the crew together.
149
483275
1532
08:18
And over the years,
over the episodes of the saga,
over the episodes of the saga,
150
486172
3916
08:22
Mr. Spock came to realize
151
490112
1588
08:23
that the combination
of both logic and emotions
of both logic and emotions
152
491724
5019
08:28
is crucial for facing challenges
and exploring new worlds,
and exploring new worlds,
153
496767
4801
08:33
and there was no contradiction anymore.
154
501592
2055
08:37
So the storyline here
for both our OLED story and Star Trek
for both our OLED story and Star Trek
155
505151
5063
08:42
is actually the basic setting
for a lot of breakthrough stories,
for a lot of breakthrough stories,
156
510238
3199
08:45
in and out of science.
157
513461
1721
08:48
The main characters
are all part of a great team.
are all part of a great team.
158
516279
3603
08:52
All team members show a huge dedication
towards reaching their goal.
towards reaching their goal.
159
520915
4437
08:58
They strive to seize
all the freedom they can get,
all the freedom they can get,
160
526710
3437
09:02
and they take the responsibility
they need to take.
they need to take.
161
530171
3165
09:07
During the time our OLED project
was nearing the end,
was nearing the end,
162
535299
3318
09:10
I received one piece of advice
several times.
several times.
163
538641
3388
09:15
"Don't take it to your heart.
164
543218
1651
09:17
You can work on something else."
165
545591
1770
09:20
If I had followed it,
166
548456
1493
09:21
it would have saved me
several depressed evenings
several depressed evenings
167
549973
3690
09:25
and many tears,
168
553687
1165
09:28
but at the same time,
169
556095
1413
09:29
I would have failed to gain a great deal
in personal development and happiness.
in personal development and happiness.
170
557532
5476
09:36
And as the same is true
for my colleagues and our whole project,
for my colleagues and our whole project,
171
564375
3335
09:39
we would have achieved far less.
172
567734
1729
09:42
So of course, science
should be based on facts and logic.
should be based on facts and logic.
173
570614
