Today is the one year anniversary of the best-worst day of your life.
0
7003
4504
今天是你生命中碰過 最糟也是最棒的一週年。
00:11
The best part was discovering a subterranean city on Mars:
1
11507
4338
最棒的部分是:過去你在火星上 發現一座地下城市,
00:15
the first evidence of intelligent alien life ever found.
2
15845
3712
更是首次發現外星智慧生命的證據。
00:19
The worst part?
3
19682
1210
那最糟糕的部分呢?
00:20
No one got to explore it,
4
20892
1585
沒人要去探索它,
00:22
because that was when you lost contact with Earth.
5
22477
2961
因為一年前你們和地球失去聯繫。
00:25
You and the other 99 scientists have spent the rest of the year
6
25563
4213
你和其他 99 位科學家 已經花了一整年
00:29
engineering your survival,
7
29776
1710
想盡辦法存活,
00:31
but you’re almost out of water and solutions.
8
31486
3211
但這時你們幾乎用盡了飲水 和生存手段。
00:34
Everyone else is at the ice cap,
9
34947
1877
其他人決定待在冰冠區探索,
00:36
but you’ve decided to investigate the buried city
10
36824
3003
但你決定前往深藏地下的都市
00:39
to see if there are clues to how their civilization survived on a desert planet.
11
39827
5089
調查文明過去是如何在 這顆荒漠星球上生存的線索。
00:45
The city is mostly ruins except for three intact pyramids—
12
45166
4963
除了三座金字塔之外, 這座城市幾乎全毀。
00:50
two open and one sealed.
13
50129
2378
其中兩座大門敞開, 另一座則大門深鎖。
00:52
In the first you find a series of symbols and pictograms,
14
52882
3629
你在第一座塔裡發現一系列的 圖案和象形符號,
00:56
revealing a fortuitously base 10 numbering system.
15
56511
4004
而且湊巧採用 10 進位制。
01:01
The second pyramid’s facade is covered in these symbols.
16
61015
3462
接著你發現第二座塔的正面 刻滿這些符號。
01:04
Inside you discover a device,
17
64477
2502
進去以後你找到一台儀器,
01:06
as well as mosaic representations of how to use it.
18
66979
3379
還有幾幅說明使用方法的鑲嵌畫。
01:10
From those you glean the following:
19
70525
2252
你從這些圖像中推敲出一些資訊:
01:12
the device is the key to opening the sealed pyramid
20
72777
3295
用這個儀器輸入中心方格裡的數字,
01:16
by inputting the number on the center block.
21
76072
2878
便能夠打開封閉金字塔;
01:19
But if you put in the wrong number, something terrible and deadly will happen.
22
79158
4338
但如果你輸入錯誤的數字, 就可能招致某種糟糕且致命的結果。
01:23
The doors to all pyramids work on the same principle.
23
83788
3754
此規則適用於所有金字塔的門。
01:27
What number should you input to open the door to the sealed pyramid?
24
87959
4546
那麼該輸入哪個數字 以開啟封閉的金字塔呢?

01:40
The pattern revealed by the second pyramid is that every number
28
100721
3838
從第二座塔的圖案可以歸納出:
每一格數字都是下層相接兩格的總和。
01:44
is the sum of the two numbers directly beneath it.
29
104559
3211
01:48
If that applies to the sealed pyramid, 40 clearly belongs to the left of 30.
30
108271
5463
如果此規律也適用於封閉的金字塔, 那麼在 30 左邊的肯定是 40 了。
01:54
The center number is the sum of 7 and an unknown, call it x.
31
114318
5172
中心的數字是七和未知數x的總和。
01:59
The value of x can be determined by trial and error,
32
119991
3712
x的值能透過嘗試錯誤來找出,
02:03
but it’s quicker to use algebraic reasoning.
33
123703
2669
但應用代數推理還是更快一些。
02:07
The number to the left of the center number is 5+x.
34
127290
4129
假設位於中心左側格子數字是 5+x,
02:11
Therefore, this block, 40, is equal to 5+x plus 7+x.
35
131419
6882
那麼 40 這一格就等同於 5+x加上7+x了。
02:18
Solving for x, x must be 14, making the central block 21.
36
138801
6090
再進一步推算後得出x為 14 , 而中心的數字為 21。
02:25
You enter 21 on the remote, and the door opens!
37
145683
3629
你用儀器輸入 21 打開了門,
02:29
Inside you find yet another riddle.
38
149520
3045
在裡頭又發現另一個謎。
02:32
The walls show the history of this civilization.
39
152565
3545
牆上記述著了這個文明的歷史。
02:36
When they lived here, the planet was covered with oceans.
40
156527
3629
當他們還定居在這的時候, 這顆星球表面覆蓋著大片海洋。
02:40
But at a certain point, they up and left Mars.
41
160156
3253
但在某個時間點, 他們搭乘飛行器離開了火星。
02:43
In order to reserve the planet for themselves
42
163618
2460
為了供日後他們回訪 這顆星球時使用,
02:46
while making it inhospitable to others,
43
166078
2628
還有讓這顆星球不適合外來者居住,
02:48
they moved all the water underground,
44
168706
2836
他們把所有的水輸往地下。
02:51
using a gigantic engineering marvel activated by a single lever.
45
171542
4755
這項工程僅憑一根搖桿操縱的 巨大機械水槽。
02:57
The lever is hidden in the Great Pyramid.
46
177340
2794
這根搖桿就藏在大金字塔的某處。
03:00
Pulling the lever again would reverse the process,
47
180301
3253
只要再度啟動搖桿便能逆轉整個過程,
03:03
and bring the water back to the surface.
48
183554
2461
讓水源再次回歸地表。
03:06
But where is this Great Pyramid?
49
186599
2210
但是這大金字塔又在哪呢?
03:08
The mosaics indicate it should be right here, but it’s clearly not.
50
188976
4129
鑲嵌畫明確地指出它應該在這, 可事實並非如此。
03:13
Without it, you have no choice but to climb back out of the city to the surface.
51
193314
5088
眼看遍尋不著,你只能離開城市、 攀上回到地表的階梯。
03:18
And that’s when you see it.
52
198402
1585
這時你發現了真相:
03:20
The city is the final pyramid, or at least one face of it.
53
200196
4880
這座城市就是最後的金字塔, 至少表面看上去如此。
03:25
A great pyramid, indeed!
54
205326
2419
這的確是座大字塔!
03:27
The city’s architects must have designed each district
55
207745
3170
城市的建築師肯定把每塊街區
03:30
to show a number when viewed from above.
56
210915
2669
設計成從上方就能看出數字。
03:33
But only these three survived the ravages of time.
57
213584
3253
可是只有這三塊區域熬過 時間的摧殘。
03:37
The key once again must be whatever number was in the center plaza.
58
217171
4213
謎底一定又是中心廣場裡的數字。
03:41
You rush there, but what number should you input into the remote?
59
221592
3796
你急忙地趕到那裡, 可是你該用儀器輸入什麼數字呢?
03:45

03:53
You could write out the algebra again, but here’s a more visual approach.
63
233479
4213
你可以再次寫出代數解題, 不過這裡有個更清晰的作法。
03:57
Sketch a pyramid, and enter the known numbers.
64
237900
3045
先把金字塔畫好, 並填入已知的數字。
04:00
Between the 9 and the 10,
65
240945
1752
在 9 和 10 之間的方格,
04:02
you can put colored dots to represent the two unknowns at the bottom.
66
242697
4170
你可以放上兩個不同顏色的點 代表底層未知的數字。
04:07
Working your way up the pyramid and drawing the sums as you go
67
247118
4129
當你逐層填入每格的總和時,
04:11
will reveal that 100 = 19 + 3 green dots
68
251247
5172
你會得出 100 等於 19 加上三個綠點
04:16
+ 3 orange dots.
69
256419
1960
再加上三個橘點。
04:18
So 3(green + orange)=81,
70
258671
4296
又得證:綠點加橘點 然後乘以 3 等於 81。
04:22
and green + orange, which is the middle number,
71
262967
3170
那麼橘點與綠點的和, 也就是中間的數字,一定是 27。
04:26
must be 27.
72
266137
1835
04:28
You don’t actually have to figure out what green and orange are—
73
268556
3962
你沒必要去算出橘點 和綠點分別是多少。
04:32
in fact, they have a number of possibilities.
74
272518
2544
事實上,他們有許多可能性。
04:35
When you enter 27, a hidden mechanism opens in the middle of the plaza,
75
275354
5339
在你輸入 27 後, 中央廣場上的一處隱藏機關啟動,
04:40
revealing a staircase.
76
280693
1877
揭露了樓梯所在。
04:42
You descend,
77
282570
1001
你進門向下走,
04:43
and finally find yourself in a room with a giant lever in the middle.
78
283571
4796
最後抵達了中央有根巨大搖桿的房間。
04:49
Only one question remains: do you pull it?
79
289076
3337
現在就剩最後一個問題: 你會拉下它嗎?
