🧐Tenet: What is time inversion? Time travel in Christopher Nolan’s new film, explained
天能:時間逆行是什麼?剖析諾蘭新片中的時間旅行
*Warning – major spoilers for Tenet below
*貼心提示:以下內容將有大量《天能》劇透
👥How do you become inverted?
In the film’s world, there are portals used to become inverted in time, which are known as “turnstiles” – these are created at some point in the future. After going through them, you can move backwards in time from the point you entered. From this point, once you enter another one, you shall move forward from the point in time you have travelled back to, meaning two versions of the same person will exist simultaneously. It is imperative you do not meet – to do so, The Protagonist is told, would cause “annihilation”.
如何成為逆行者?
在電影裡面,有進入之後就可以「逆時而行」的機器,稱為旋轉門。旋轉門是未來的產物,進入之後可以逆時而行。之後再進入一個旋轉門就可以重新進入順行時空,但是是從第二次進入旋轉門的時間開始順行,也就是說,可能會有兩個主角同時存在同一個時空中。這兩個主角絕對不能接觸彼此,主角在電影中被告知,接觸時空中的另一個自己會造成自我毀滅。
💣Inverted bullets
The reason why objects – including guns and bullets – can move backwards in present time is because these things have manually had their entropy reversed at some point in the future (entropy measurement is a way of distinguishing the past from the future).
「逆熵」的子彈
特定的物品 – 包括槍和子彈 – 可以在現行時空逆行的原因是,這些物品在未來的某一時間點上被人進行了逆熵的行為 (熵測度是一種分辨過去和未來的方式)。
🕐What is the Temporal Pincer Movement?
It is a tactic used by people who move through the turnstiles to help you receive knowledge you learned in the future. Once the information has been learnt, the idea is to then invert yourself, so you can brief either past self or someone else. This, in turn, creates a loop of information.
時間鉗形攻勢是什麼?
時間鉗形攻勢是透過逆轉門獲取未來知識,一但掌握到未來的情況就可以逆轉自己,告知過去的自己或過去時空的人,藉此產生資訊迴圈。

張亞勤2020寄語哥倫比亞大學畢業生:引領未知時代
2020年5月18日,人工智慧和數位視訊的世界級科學家和企業家,美國藝術與科學院院士、百度前總裁、清華大學智慧科學講席教授張亞勤博士,在哥倫比亞大學工程學院的畢業典禮上發表了主題演講。
張亞勤說:“面對全球疫情,技術成為最關鍵的變革力量,高速網路、軟體和人工智慧等基礎技術塑造我們生活、學習、工作和娛樂方式。”他提到:“隨著世界進入一個充滿挑戰和不確定性的新階段,年輕工程師迎來了回應歷史使命的決定性時刻,不僅要以技術創新,還要以同理心、勇氣和人文主義精神來迎接使命。”
哥倫比亞大學工程學院院長瑪麗·博伊斯(MaryC. Boyce)表示:“我們很高興能請到張亞勤博士(Dr.Ya-Qin Zhang)給我們的畢業生做演講,以此來紀念這一重要的里程碑。”她談到:“我們的畢業生將進入一個變化的世界,他們也將成為時代變化的締造者。學生們將受益張亞勤博士的觀點,其非凡職業道路也將鼓舞學生們。”(引用哥倫比亞大學新聞報導)
以下為百度前總裁、清華大學智慧科學講席教授張亞勤在2020年哥倫比亞大學工程學院畢業典禮上的致辭全文:
尊敬的Bollinger校長, Boyce院長,家長們,同學們,大家好。
我很榮幸能夠在這個非常時期,以特殊的形式出席這次特別的典禮。首先,恭喜2020屆畢業生,對你們取得的傑出成就表示衷心祝賀。你們做到了!
我也是一名哥倫比亞大學的學生家長。我的兒子現在哥大工學院二年級學生,我女兒是哥大商學院2020屆的畢業生。我想與所有家長分享這份難以言表的喜悅和驕傲,我們都做到了!
這無疑是我們有生記憶以來最具挑戰性和不確定性的一個時期。
我們不僅看到了科技創新的極速進步和第四次工業革命的巨大力量,人工智慧、納米技術、量子電腦和5G通信等等技術不斷突破。
我們還目睹了百年一遇的流行疾病在全球範圍內帶來的突發性破壞和災難性影響,對我們的社會基礎、經濟結構和生活方式帶來挑戰。
對於那些學習過熱力學第二定律的人來說,“熵”這個術語一定不陌生,它表示動態系統中的混沌程度(Chaos)。資訊理論的創始者Claud Shannon將這一概念擴展到了資訊的不確定性和隨機性。可以說,2020屆畢業生是被賦予“熵”值最高的一屆。未來的不可預測和混沌程度都是前所未有的。對你們如此,對我們所有人也是如此。
與你們的交流令我回想起我的學生時代和年輕時的工程師工作經歷。1990年畢業後,我的第一份工作是開發演算法,壓縮圖像和視頻,完成遠端傳輸,對國際標準MPEG和H.26x做出一點小貢獻:MPEG和H.26x也是如今Netflix、YouTube、Skype和Zoom等流行視頻應用程式的重要基礎。在過去的三十年裡,我有幸一直在激動人心的創新技術中徜徉, HDTV、自動駕駛、人工智慧和雲計算等等。在這一路走來,收穫的不僅是無窮的樂趣,也有超凡的艱辛。我想跟同學們分享我的三個體會:
1)在數據爆炸和不斷變化的世界中,成為具備強適應能力的學習者。在瞬息萬變的技術行業中,五年前學到的知識大多已無用處。你們在哥倫比亞大學中學習到最有價值的是學習新知的能力,是從繁雜噪音中分別信號的能力,是從眾多數據中提取“熵”的能力。我有一個行之有效的習慣,每天早上花10分鐘,找出對我而言最新的發現或最重要的3件事情,當天來學習。
2) 要擁有獨特的觀點和視角。當你們進入現實世界,會自然而然的開始被“打磨”,去遵循已有的趨勢,融入他人。我懇請你們保持自己的尖銳、棱角和與眾不同。當我與年輕工程師面聊時,我期待他們的觀點、他們的“熵”、他們鮮活的想法,這些遠比圓滑、打磨、“正確”要重要得多。
3) 無論做什麼事情,要秉承道德和人性。兩千多年前,偉大的希臘思想家蘇格拉底將道德作為追求真理的靈魂。大約同一時期,偉大的中國哲學家孔子把人性的“仁義”作為社會結構的基礎。在截然不同的文化下,兩位偉大思想家所見略同,並非巧合。今天,當我們面臨更多選擇、迷茫和誘惑時,這一點就變得更加重要。技術是中立的,但創新者是有使命的。技術是工具,但技術人員是為人類服務的。院長Mary Boyce對哥倫比亞工學院提出的願景“技術以人為本”是工程學的核心,也是我們工程師和技術人員的宗旨。
年輕的朋友們,對你們而言,這是一個決定性的時刻,請盡情的用你們的才華、激情和創新,更用你們的同理心,勇氣和人性,去展現,去閃耀,回應使命的召喚!
再次恭喜你們,2020屆畢業生!

張亞勤哥倫比亞大學畢業典禮演講英文原文:
Leading in times ofuncertainty
President Bollinger, Dean Boyce, Parentsand Students:
I am honored to be here at this veryspecial occasion, at a very special time, in the most special form. First, abig congratulation to the class of 2020 for your remarkable accomplishments. Youmade it!
I am also a proud parent of Columbia.My son is a rising junior at the engineering school, and my daughter is also aclass 2020 for the business school. I share the immense joy and incrediblepride with all the parents, we all made it too!
This is undoubtedly the mostchallenging and uncertain time in our living memory.
We see the staggering pace ofinnovation and the transformative power of the fourth industrial revolution,with technology breakthroughs such as artificial intelligence, nano-technology,quantum computing, and 5G advanced communications.
We also see the sudden disruption andcatastrophic impact of the once-in-a-century pandemic at a global scale thatchallenges the very foundation of our social fabric, economic structure, andlife style.
For those of you who have learned the 2ndlaw of thermodynamics, you know the term “entropy”, which represents degree of chaosin a dynamic system. Claud Shannon, the founding father of information theory,extended this notion to measure information uncertainty and randomness. It’s fair to say that the Class of 2020 is the one that is “given” the highest entropy. The level ofunpredictability and chaos is unprecedented for you -- and for all of us.
Talking with you reminds me of my earlyyears as a student and young engineer. My first job after graduation in 1990was developing algorithms to compress imagery and video for remote transmission,essentially to extract the maximum entropy. The work eventuallycontributed in a small way to a set of international standards known as MPEGand H.26x, the base for today’s popular video applications used in Netflix, YouTube, Skype andZoom. Over last three decades, I had the distinct opportunity to work on someof the most exciting technologies such as HDTV, autonomous driving, AI, and cloudcomputing. I have had the wildest ride with not only a great deal of fun, butalso extraordinary hardship along the way. Let me share with you three of mypersonal learnings:
1) Be an adaptive learner in the world of dataexplosion and constant change. In today’s fast changing technology industry, most of what you learned fiveyears ago is irrelevant. The most valuable skill you’vegained at Columbia is the ability to learn new things, to discern the signalfrom the noise, and to extract entropy from the ocean of data. One routine Ifind particularly helpful is to commit just 10 minutes each morning and prioritize3 things – anything new and important to me – to learn that day.
2) Have a unique point of view and perspective. When you get into the realworld, there is a natural tendency to become “polished”, to follow existing trends, and toblend in with the rest.
I ASK you tomaintain your sharpness, your edge, and your differences. When I interviewpeople, particularly young engineers, I look for their point of view, theirentropy, and their flash of ideas, which to me is far more important than beingsmooth, polished or “correct”.
3) Hold Ethics and humanity at theheart of what you do. Over 2000 years ago, the great Greek thinker Sock-ruh-tease put ethics as the soul forthe pursuit of truth. Around the same time, the great Chinese philosopher Confuciusplaced “Renyi”, whichessentially means humanity, as the foundation for social structure. It is nocoincidence that two of the greatest minds from vastly different cultures hadthe same idea. This has become even more critical today as we all face morechoices, confusion, and temptations. Technology is neutral, but innovatorshave purpose. Engineering is a tool, but engineers serve humanity. “Engineering for Humanity”, the vision set byDean Mary Boyce for Columbia engineering is the very core of engineering andwhat engineers are all about.
My youngfriends, this is the defining moment for you, for you to rise, to shine andanswer the historic call of duty, with not only your talent, spark andinnovations, but also compassion, courage and humanity.
Congratulations again, Class 2020 !

[Undressing the Big Verticals: Finding Disruption Strategies in Greater Southeast Asia]
Huge businesses online and offline wear a facade of dominance. In a world where software and cloud storage is cheap compared to even five years ago, these facades are just facades.
Any smart founder who can understand a niche market and its customers, can disrupt these businesses by offering a much better experience to a global set of users, simply by showing that the emperors wear no clothes.
Take a look at the first photo. Each of the eight startup companies in the first image were taken out of the listings page (literally) of online classifieds business Craigslist, depicted in the second picture. This platform's offerings became so big and varied that it suffered from entropy.
The markets tapped into by these startups are bigger than what Craigslist alone could utilize. Meaning that the gold threads Craigslist was wearing were really just a myth. As submarkets became exploitable, startup founders started picking them off.
These two images offer great insights for founders in Greater Southeast Asia, where businesses are sometimes conservatively managed, and where conglomerates and gigantic industry players operate in large local markets.
This is because the new companies do one niche thing very well dating; food; home-sharing, etc. In a mobile-use heavy market, people love these apps. The focused offerings and their ease of use make them fun to use, and they solve problems quickly and efficiently.
Why does this happen? What should founders in GSEA do with this information?
1. There are two reasons why this happens. First, big platforms trying to do everything for everyone will find it hard to manage all of the areas of the business. It's a result of organizational entropy. Consumers in a diverse global software environment will be easily distracted by new choices that big organizations cannot exploit in a fast way.
It also happens because founders using cheaper and more agile software tools can find niche areas in big platforms that they can exploit much more quickly, and offer to consumers using a better user experience. They understand the needs of the niche customer better. They find ways to make it interesting and engaging.
After all, swiping left and right on Tinder is actually really fun and an engaging use of time. Right?
2. Founders in GSEA are working in a region where it should be relatively easy to find big industry players in the market and find ways of disrupting their existing dominance.
In a region that is still relatively conservative in business compared to the rest of the world, and where large conglomerate players usually dominate the local markets, software disruption is primed and ready.
If you would like to test out exploits and software platform ideas in niche areas dominated by big industry players in a gigantic market, check out our accelerator class #20.
We are taking applications until December 16. Join here: http://bit.ly/AWdisrupt
