“X-ray”一词可以追溯到
00:17
to the work of Rene Descartes,

笛卡尔在数学界的
00:28
to the world of numbers
10
28344
1422
众多贡献之一是
00:29
was the invention of a simple yet brilliant convention
11
29766
3485
发明了一个简洁而好用的惯例,
00:33
most people take for granted today:
12
33251
2906
一个大多数人今日习以为常的惯例,
00:36
the representation of unknowns
13
36157
2169
那就是在方程式中用
00:38
within an equation as X, Y, and Z.
14
38326
4777
X,Y,Z来代表未知量。
00:43
When the German scientist Wilhelm Rontgen
15
43103
3234
当德国科学家伦琴
00:46
discovered what we now call X-rays
16
46337
1946
在19世纪发现了我们现在
00:48
in the late 19th century,
17
48283
2061
所称的“X-ray”之后,
00:50
he gave them the name X-strahlen.
18
50344
3396
他给它起名叫“X-strahlen”。
00:53
Strahlen is German for shine,
19
53740
2594
“Strahlen”是德语照射的意思,
00:56
and X, of course, represented the unknown nature
20
56334
3982
而X,自然就是指伦琴发现的这种辐射
01:00
of the radiation Rontgen had discovered,
21

3072
的未知属性。
01:03
the X-factor, so to speak.
22
63388

X因子,也可以这么说。
01:06
The English translation maintained the X
23
66434
2825
英文翻译保留了“X”,
01:09
but replaced the German shine with ray,
24
69259
3658
但将德语“shine”换成了“ray”,
01:12
meaning a beam of light.
25
72917
2657
意思是一束光。
01:15
Coincidentally, in mathematics,
26
75574
2214
巧合的是,数学中,
01:17
the word ray refers to a line
27
77788
2058
“ray”指的是直线,
01:19
with a point of origin that has no end
28
79846
2875
有起点而无尽头,
01:22
and extends to infinity,
29
82721
2312
延伸至无穷,
01:25
bringing us neatly back to the unknown.
30
85033
2943
这就又把我们带回了未知中。
01:27
Today we understand what X-radiation is,
31
87976
3818
今天,我们明白了X光是什么,
01:31
and in spite of the humble objections
32

01:33
of its discoverer,

它的属性对我们也不再神秘。
