1
00:00:04,420 --> 00:00:07,221
Kujuta ette, et me elame eelajaloolisel ajal.

2
00:00:07,221 --> 00:00:09,468
Nüüd, arvesta järgnevat:

3
00:00:09,468 --> 00:00:12,721
Kuidas me aega arvestasime ilma kellata?

4
00:00:12,721 --> 00:00:15,315
Kõik kellad põhinevad mingil korduval mustril,

5
00:00:15,315 --> 00:00:18,890
mis jagab aja voolu võrdseteks segmentideks.

6
00:00:18,890 --> 00:00:20,688
Et leida neid korduvaid mustreid,

7
00:00:20,688 --> 00:00:22,918
vaatame me taevasse.

8
00:00:22,918 --> 00:00:24,902
Päikese tõus ja loojang iga päev

9
00:00:24,902 --> 00:00:26,184
on kõige ilmsem[muster].

10
00:00:26,184 --> 00:00:28,760
Kuid, et jälgida pikemaid aja perioode,

11
00:00:28,760 --> 00:00:30,811
otsisime pikemaid tsükleid.

12
00:00:30,811 --> 00:00:32,512
Selleks, vaatasime kuud,

13
00:00:32,512 --> 00:00:33,853
mis tundus järk-järgult kasvavat

14
00:00:33,853 --> 00:00:36,578
ja kahanevat üle paljude päevade.

15
00:00:36,578 --> 00:00:37,894
Kui me lugesime päevade arvu

16
00:00:37,894 --> 00:00:38,978
täiskuude vahel,

17
00:00:38,978 --> 00:00:40,910
jõudsime numbrini 29.

18
00:00:40,910 --> 00:00:42,833
See on kuu algallikas.

19
00:00:42,833 --> 00:00:45,873
Kuid, kui me üritame jagada 29 võrdseteks tükkideks,

20
00:00:45,873 --> 00:00:49,227
me jookseme probleemi otsa: see on võimatu.

21
00:00:49,227 --> 00:00:51,676
Ainuke võimalus jagada 29 võrdseteks juppideks

22
00:00:51,676 --> 00:00:54,819
on murda see [29] üksikuteks tükkideks.

23
00:00:54,819 --> 00:00:57,102
29 on 'algarv'

24
00:00:57,102 --> 00:00:59,061
Mõtle sellest, kui lõhkumatust.

25
00:00:59,061 --> 00:01:00,879
Kui numbrit saab murda

26
00:01:00,879 --> 00:01:02,814
võrdseteks ühest suuremateks juppideks,

27
00:01:02,814 --> 00:01:04,621
kutsume seda 'kordarvuks.'

28
00:01:04,621 --> 00:01:06,608
Nüüd, kui oleme uudishimulikud, võime mõelda,

29
00:01:06,608 --> 00:01:08,450
"Kui palju algarve on olemas?

30
00:01:08,450 --> 00:01:10,398
- ja kui suureks nad lähevad?"

31
00:01:10,398 --> 00:01:13,744
Alustame sellega, et jagame kõik numbrid kahte kategooriasse.

32
00:01:13,744 --> 00:01:15,611
Reastame algarvud vasakule

33
00:01:15,611 --> 00:01:17,648
ja kordarvud paremale.

34
00:01:17,648 --> 00:01:20,379
Esmalt tunduvad nad tantsivat edasi-tagasi.

35
00:01:20,379 --> 00:01:23,017
Ei ole ilmset mustrit siin.

36
00:01:23,017 --> 00:01:24,439
Niisiis, kasutame kaasaegset tehnikat,

37
00:01:24,439 --> 00:01:26,077
et näha suurt pilti.

38
00:01:26,077 --> 00:01:29,047
Trikk seisneb "Ulami spiraali" kasutamises.

39
00:01:29,047 --> 00:01:32,011
Esmalt joondame kõik võimalikud numbrid järjest

40
00:01:32,011 --> 00:01:34,043
kasvavasse spiraali.

41
00:01:34,043 --> 00:01:37,164
Siis värvime kõik algarvud siniseks.

42
00:01:37,164 --> 00:01:41,290


43
00:01:41,290 --> 00:01:42,860


44
00:01:42,860 --> 00:01:45,365


45
00:01:45,365 --> 00:01:47,967


46
00:01:47,967 --> 00:01:50,314


47
00:01:50,314 --> 00:01:51,843


48
00:01:51,843 --> 00:01:52,987


49
00:01:52,987 --> 00:01:55,526


50
00:01:55,526 --> 00:01:58,183


51
00:01:58,183 --> 00:01:59,411


52
00:01:59,411 --> 00:02:02,607


53
00:02:02,607 --> 00:02:04,896


54
00:02:04,896 --> 00:02:07,078


55
00:02:07,078 --> 00:02:10,599


56
00:02:10,599 --> 00:02:12,921


57
00:02:12,921 --> 00:02:15,760


58
00:02:15,760 --> 00:02:17,148


59
00:02:17,148 --> 00:02:20,542


60
00:02:20,542 --> 00:02:23,317


61
00:02:23,317 --> 00:02:25,674


62
00:02:25,674 --> 00:02:28,037


63
00:02:28,037 --> 00:02:30,518


64
00:02:30,518 --> 00:02:33,354


65
00:02:33,354 --> 00:02:34,774


66
00:02:34,774 --> 00:02:37,675


67
00:02:37,675 --> 00:02:40,221


68
00:02:40,221 --> 00:02:41,996


69
00:02:41,996 --> 00:02:46,157


70
00:02:46,157 --> 00:02:48,032


71
00:02:48,032 --> 00:02:50,759


72
00:02:50,759 --> 00:02:52,013


73
00:02:52,013 --> 00:02:53,934


74
00:02:53,934 --> 00:02:55,501


75
00:02:55,501 --> 00:02:57,233


76
00:02:57,233 --> 00:02:59,763


77
00:02:59,763 --> 00:03:01,624


78
00:03:01,624 --> 00:03:05,811


79
00:03:05,811 --> 00:03:07,906


80
00:03:07,906 --> 00:03:10,714


81
00:03:10,714 --> 00:03:12,739


82
00:03:12,739 --> 00:03:13,780


83
00:03:13,780 --> 00:03:16,178


84
00:03:16,178 --> 00:03:20,158


85
00:03:20,158 --> 00:03:23,153


86
00:03:23,153 --> 00:03:24,887


87
00:03:24,887 --> 00:03:27,110


88
00:03:27,110 --> 00:03:28,792


89
00:03:28,792 --> 00:03:31,276


90
00:03:31,276 --> 00:03:34,046


91
00:03:34,046 --> 00:03:36,299


92
00:03:36,299 --> 00:03:38,017


93
00:03:38,033 --> 00:03:39,722


94
00:03:39,722 --> 00:03:42,054


95
00:03:42,054 --> 00:03:43,937


96
00:03:43,937 --> 00:03:47,889
