人類歷史上最大的未解之謎是什么？

People often tend to forget that. We are so busy exploring outer space yet half of the ocean isn't even mapped.

人們經(jīng)常忘記這點(diǎn)。我們太忙著探索宇宙空間了，但是海洋卻還沒有記錄一半。

neither medicine nor science has an answer for what consciousness is, or where it originates

醫(yī)學(xué)和科學(xué)都不能解釋意識(shí)是什么，或者意識(shí)的起源是什么。

Emergence as a concept is crazy. Like an atom of an orange doesn’t contain “orange-ness”, but if you put billions of them together then they do.

涌現(xiàn)這個(gè)概念真的很瘋狂。舉個(gè)例子，橘子的一個(gè)原子并不包含“橘子性”，但是如果把無數(shù)個(gè)原子放在一起，它就是橘子了。

Between 1200 and 1150 BCE, most of the civilizations in the Eastern Mediterranean region were either greatly depleted or collapsed entirely, bringing an abrupt end to the Bronze Age. These civilizations were massively depopulated, their palaces and cities were destroyed or abandoned, and some transformed into small, isolated village cultures or nomadic herders. The Greek Linear B scxt was lost, and there is no written record of the following period of Greek history, meaning that Greeks of the time were probably illiterate.

在公元前1200年至1150年之間，地中海東側(cè)地區(qū)的絕大多數(shù)文明都要么嚴(yán)重衰退了，要么徹底崩潰了，青銅時(shí)代因而唐突中止。這些文明的人口都發(fā)生了嚴(yán)重的衰退，他們的宮殿和城市要么被摧毀，要么被遺棄，有些文明變成了與世隔絕的村莊文化，或是游牧民族。希臘的線形文字B失去了傳承，并且在希臘歷史的接下來那段時(shí)間都沒有書面記錄，這證明當(dāng)時(shí)的希臘人很可能都不識(shí)字。

This rapid decline affected - to one extent or another - major historical powers like Mycenaean Greece, New Kingdom Egypt, the Hittite Empire, and Assyria, among others.

這場(chǎng)迅速的衰退一定程度上也影響了歷史上的其他強(qiáng)國(guó)，比如希臘的邁錫尼文明，埃及的新王國(guó)，赫梯帝國(guó)，亞述帝國(guó)等。

And we don't know why it happened.

我們都不知道為什么發(fā)生了。

These were sprawling, thriving civilizations, with healthy economies, elaborate trade networks, complex bureaucracy, written language, and large-scale agriculture, and they just...died. For some reason. There are plenty of theories, of course, but ultimately there's no conclusive evidence that tells the story of how the Bronze Age collapsed into the intermediate period that preceded the Iron Age.

那些都是四處擴(kuò)張，生機(jī)勃勃的文明，經(jīng)濟(jì)十分健康，貿(mào)易網(wǎng)絡(luò)十分精致，官僚系統(tǒng)十分復(fù)雜，有書面語言，也有大規(guī)模的農(nóng)業(yè)，然后他們忽然就……死了。不知什么原因。當(dāng)然有很多的理論來解釋，但到頭來還是沒有決定性的證據(jù)，能夠證明銅器時(shí)代是怎樣突然崩潰到那個(gè)鐵器時(shí)代之前的過渡時(shí)代的。

It was a perfect storm basically. Drought, famine, volcanic winter, pandemic, advances in technology and new warfare.

是一場(chǎng)恰到好處的完美風(fēng)暴。干旱，饑荒，火山噴發(fā)導(dǎo)致的寒冬，瘟疫，科技的進(jìn)步和新的戰(zhàn)爭(zhēng)。

Tree rings and other scientific evidence show that there was a terrible drought, the water level in the Dead Sea dropped more than 50m. It was suspected that crop failures, famine and the population reduction that resulted from the lackluster flow of the Nile and the migration of the Sea Peoples led to New Kingdom Egypt falling into political instability at the end of the Late Bronze Age.

年輪和其他科學(xué)證據(jù)表明，曾經(jīng)發(fā)生過一場(chǎng)嚴(yán)重的干旱，死海的水位下降過超過50米。有人懷疑是尼羅河水位下降，以及海洋民族的遷徙導(dǎo)致的田地歉收，饑荒以及人口減少，一系列因素導(dǎo)致了埃及新王國(guó)在銅器時(shí)代晚期陷入了政治不穩(wěn)定。

Recent evidence suggests the collapse of the cultures in Mycenaean Greece, Hittite Anatolia, and the Levant may have been precipitated or worsened by the arrival of an early and now-extinct strain of the Bubonic Plague that was brought from central Asia by the Sea Peoples or other migrating groups.

最近的證據(jù)表明，邁錫尼希臘文明，安納托利亞的赫梯文明，以及黎凡特地區(qū)各文明的崩潰，或許都與海洋民族或其他遷徙民族從中亞帶來的一種，現(xiàn)在已經(jīng)滅絕的鼠疫分支的到來有關(guān)

Iron was more plentiful and allowed larger iron armies to destroy smaller Bronze armies. Cast swords became more popular with large groups of raiders and it made it easy to cut down the chariot armies which were common in the ruling civilizations.

鐵的產(chǎn)量越來越多，因此規(guī)模更大的、裝備了鐵質(zhì)武器的軍隊(duì)就可以摧毀更小的銅器軍隊(duì)了。鑄鐵劍變得更加流行，從而能夠組織更大規(guī)模的輕騎兵，這樣擊敗敵方的馬車軍團(tuán)就能更輕松了，而馬車軍團(tuán)是當(dāng)時(shí)的統(tǒng)治文明廣泛使用的。

Back in 2002 I folded and placed three $100 bills in my back right pocket while standing in my living room. I grabbed my wallet from the bar, walked to the front door where I decided it was safer to transfer the $100s to my wallet.

2002年，我站在起居室里，拿起三張100美元的鈔票，疊起來放到了我的右屁股兜里。我從吧臺(tái)上拿了錢包，走到前門，然后我覺得把鈔票放到錢包里可能更安全一點(diǎn)。

My pocket was empty.

我的屁股兜里啥也沒有。

There was no one else home. I looked everywhere for more than an hour. This episode has seriously damaged my sanity and self esteem.

家里也沒有別人。我到處找了半天，找了一個(gè)多小時(shí)。這件事嚴(yán)重地?fù)p傷了我的理智，以及我的自尊。
