Mysteries of vernacular:
1

00:17
Dynamite,
2
17271
1616
00:18
an explosive consisting of nitroglycerin,
3
18887
3039
00:21
typically molded into sticks.
4
21926
2328
00:24
Dynamite, which coincidentally is closely related
5
24254
3170
00:27
to the word dynasty,
6
27424
1721
00:29
has as much to do with familial persuasion
7
29145
2833
00:31
as it does etymology.
8
31978
2834
00:34
Following in the footsteps of his inventor father,
9
34812
2795
00:37
Alfred Nobel took up engineering.
10
37607
2999
00:40
In 1850, he was exposed to the work of Ascanio Sobrero,
11
40606
5258
00:45
the chemist who invented nitroglycerin.
12
45864
2989
00:48
More powerful than gun powder
13
48853
1808
00:50
and extremely unpredictable,
14
50661
1920
00:52
this highly explosive liquid captivated Alfred.
15
52581
4210
00:56
Working closely with his father,
16
56791
2042
00:58
he began experimenting with nitroglycerin,
17
58833
2881
01:01
searching for a practical application for the compound.
18
61714
3628
01:05
After several explosions,
19
65342
2197
01:07
including one that killed Alfred's brother,
20
67539
2725
01:10
authorities banned nitroglycerin tests
21
70264
2969
01:13
within Stockholm city limits.
22
73233
2536
01:15
Undeterred, Alfred moved his lab
23
75769
2407
01:18
and began experimenting with additives,
24
78176
2308
01:20
eventually finding one that transformed
25
80484
2498
01:22
the dangerous liquid into malleable paste,
26
82982
3231
01:26
easier to handle
27
86213
1489
01:27
and perfect for construction sites.
28
87702
2841
01:30
He named this material dynamite,
29
90543
2543
01:33
from the Greek dunamis,
30
93086
2153
01:35
meaning power,
31
95239
1594
01:36
and the common scientific suffix -ite.
32
96833
3503
01:40
Explosives made Alfred a very wealthy man.
33
100336
3751
01:44
And, in an effort to balance
34
104087
1212
01:45
the destruction caused by his invention,
35
105299
2832
01:48
he created an endowment
36
108131
1851
01:49
that would award Nobel Prizes
37
109982
2227
01:52
to authors,
38
112209
972
01:53
scientists,
39
113181
1211
01:54
and advocates of world peace
40
114392
2269
01:56
for generations to come.
