00:00:00,470 --> 00:00:02,510
今天的《分析模式》漫谈

2
00:00:02,760 --> 00:00:06,700
我们来说一个有趣的台球杀人事件

3
00:00:08,640 --> 00:00:09,630
还是第一章

4
00:00:09,920 --> 00:00:12,020
这里有一句，you would

5
00:00:12,030 --> 00:00:12,620
need

6
00:00:12,630 --> 00:00:13,580
to look

7
00:00:13,590 --> 00:00:14,460
behind the

8
00:00:14,470 --> 00:00:15,300
surface to

9
00:00:15,310 --> 00:00:17,050
understand the

10
00:00:17,060 --> 00:00:18,690
laws of motion

11
00:00:18,700 --> 00:00:20,450
that relate

12
00:00:20,840 --> 00:00:22,800
mass, velocity

13
00:00:22,810 --> 00:00:23,640
momentum

14
00:00:23,650 --> 00:00:24,760
and the like

1
00:00:01,800 --> 00:00:05,220
2004中译本

2
00:00:05,730 --> 00:00:09,560
机械工业出版社，翻译，蕴含的规律

3
00:00:09,570 --> 00:00:12,000
其中涉及到质量、速度

4
00:00:12,010 --> 00:00:14,230
动量，这个基本可以

5
00:00:15,490 --> 00:00:16,760
当然这个应该是定律

6
00:00:18,440 --> 00:00:19,570
不是规律

7
00:00:21,550 --> 00:00:23,140
但是后面这个是对的

8
00:00:24,010 --> 00:00:26,410
定律，涉及到什么概念的定律

9
00:00:27,450 --> 00:00:28,800
但是2020中译本

10
00:00:29,170 --> 00:00:30,200
人民邮电出版社

11
00:00:32,410 --> 00:00:34,930
了解其背后的运动定律

12
00:00:34,940 --> 00:00:37,800
包括质量、速度、动量等

13
00:00:38,450 --> 00:00:39,570
这个就不太对了

14
00:00:40,150 --> 00:00:44,070
因为质量、速度、动量，它并不是运动定律

15
00:00:44,280 --> 00:00:47,270
而是说这个运动定律里面涉及到它们

16
00:00:51,830 --> 00:00:52,950
实际上这个是什么定律

17
00:00:54,960 --> 00:00:58,250
就是我们动量的公式

18
00:00:59,540 --> 00:01:03,700
我们中学学的，p=mv

19
00:01:04,410 --> 00:01:08,590
但是这是低速下面的，严格一点

20
00:01:08,960 --> 00:01:12,940
要把光速考虑上

21
00:01:13,240 --> 00:01:18,420
这个是高速下面，还要加一个洛伦兹因子

22
00:01:20,700 --> 00:01:21,900
当然如果这个v很小

23
00:01:22,110 --> 00:01:24,580
下面这个就基本上等于1了

24
00:01:24,590 --> 00:01:26,850
你看，动量

25
00:01:27,500 --> 00:01:28,930
质量，速度

26
00:01:29,430 --> 00:01:31,770
还有一个常数光速

27
00:01:32,540 --> 00:01:34,670
这个是定律

28
00:01:36,230 --> 00:01:39,260
涉及到了这几个的一个东西

29
00:01:42,160 --> 00:01:43,310
说到这个的话

30
00:01:43,320 --> 00:01:48,810
再联想到这里说的是斯诺克，台球

31
00:01:50,470 --> 00:01:55,350
阿西莫夫有一篇很有名的小说，台球

32
00:01:56,130 --> 00:02:00,620
用物理定律，用台球杀人

33
00:02:02,910 --> 00:02:07,130
台球就把他心脏给冲掉了

34
00:02:09,630 --> 00:02:09,920
为什么

35
00:02:09,930 --> 00:02:12,790
他因为他误解了物理定律

36
00:02:12,800 --> 00:02:14,490
以为没事

37
00:02:15,080 --> 00:02:18,120
结果被他的朋友给谋害了

38
00:02:20,410 --> 00:02:22,280
