The black swan theory or theory of black swan events


這些事肯定都會在 2017 年發生。但真正的黑天鵝事件是什麼?——亦即現在不在我們的視野之內,卻會擾亂金融市場的事件?
(譯注:歐洲人以前所見的天鵝都是白色,所以認為天鵝都是白色。直到在澳洲看到黑天鵝,才對天鵝的認識改觀。「黑天鵝」指那些一旦發生,就會產生使人改觀的意外事件。)


From Wikipedia, the free encyclopedia
The black swan theory or theory of black swan events is a metaphor that describes an event that comes as a surprise, has a major effect, and is often inappropriately rationalized after the fact with the benefit of hindsight. The term is based on an ancient saying which presumed black swans did not exist, but the saying was rewritten after black swans were discovered in the wild.
The theory was developed by Nassim Nicholas Taleb to explain:
  1. The disproportionate role of high-profile, hard-to-predict, and rare events that are beyond the realm of normal expectations in history, science, finance, and technology.
  2. The non-computability of the probability of the consequential rare events using scientific methods (owing to the very nature of small probabilities).
  3. The psychological biases which blind people, both individually and collectively, to uncertainty and to a rare event's massive role in historical affairs.
Unlike the earlier and broader "black swan problem" in philosophy (i.e. the problem of induction), Taleb's "black swan theory" refers only to unexpected events of large magnitude and consequence and their dominant role in history. Such events, considered extreme outliers, collectively play vastly larger roles than regular occurrences.[1]:xxi More technically, in the scientific monograph 'Silent Risk',[2] Taleb mathematically defines the black swan problem as "stemming from the use of degenerate metaprobability".[2]

Background[edit]

The phrase "black swan" derives from a Latin expression; its oldest known occurrence is the poet Juvenal's characterization of something being "rara avis in terris nigroque simillima cygno" ("a rare bird in the lands and very much like a black swan").[3]:165 When the phrase was coined, the black swan was presumed not to exist. The importance of the metaphor lies in its analogy to the fragility of any system of thought. A set of conclusions is potentially undone once any of its fundamental postulates is disproved. In this case, the observation of a single black swan would be the undoing of the logic of any system of thought, as well as any reasoning that followed from that underlying logic.
Juvenal's phrase was a common expression in 16th century London as a statement of impossibility. The London expression derives from the Old World presumption that all swans must be white because all historical records of swans reported that they had white feathers.[4] In that context, a black swan was impossible or at least nonexistent.

When Joseph Schwab was pulled over in August 2015, he was booked for misdemeanor driving under the influence of a drug. But his blood alcohol level was 0.00%, and he tested negative for benzodiazepines, cocaine, opiates, THC, carisoprodol (a muscle relaxant), methamphetamine/MDMA, oxycodone, and zolpidem.
The only drug for which he tested positive? Caffeine.

lidar 

Pronunciation: /ˈlʌɪdɑː/ 


NOUN

[MASS NOUN]
detection system which works on the principle of radar, but uses light from a laser.
Example sentences
  • Automotive manufacturers are looking at technologies that include radar and lidar to make such measurements, and could have the systems on the market within two or three years.
  • With the combination of GPS and inertial systems, and the use of a lidar (light detection and ranging) system, the plane's exact recording position and precise topographical data on the earth's surface can be ascertained.
  • The pulse energies in the solid-state laser can be higher since these lasers store energy longer and more efficiently than fiber lasers, and this higher power improves the performance of lidar and remote-sensing systems.

Origin

1960s: blend of light1 and radar.
More
  • radar from [M20]:
    This system for detecting objects by sending out radio waves which are reflected back was developed in the 1930s. The name comes from the opening letters of radio detection and ranging, and was coined in 1941. Police started using radar traps to detect speeding motorists in the early 1960s. In the Second World War the myth that pilots ate lots of carrots to help them see in the dark was spread to explain how they could detect enemy planes, as radar was still a secret. Other words have been coined on the pattern of radar, such as lidar (mid 20th century), which works like radar, but uses light from lasers (mid 20th century)—laser itself being an acronym from ‘light amplification by the stimulatedemission of radiation’.

光學雷達英語:lidarLIDARLiDAR),或簡稱光達,是一種光學遙感技術,它通過向目標照射一束,通常是一束脈衝雷射來測量目標的距離等參數。雷射雷達在測繪學考古學地理學地貌地震林業遙感以及大氣物理等領域都有應用[1] 此外,這項技術還用於機載雷射地圖測繪、雷射測高、雷射雷達等高線繪製等等具體應用中。
雷射雷達對物體距離的測量與通常所說的雷達類似,都是通過測量發送和接受到的脈衝信號的時間間隔來計算物體的距離。因此,由於原理上的相似性,儘管雷達的準確定義是使用微波或無線電波等波長較長的電磁波進行檢測測距的設備,雷射雷達這一術語仍然被廣泛使用。

kowtow

 kowtow:少數百多年前的中文詞彙走入英文



民報


【楊憲宏專欄】
從2012年就成立「想想論壇」的蔡英文,四年後,上了美國《外交政策》期刊「全球百大思想家」名單。讓人有點納悶,沒有發表思想哲學著作的蔡英文,為什麼會被外國人認證為「思想家」?難道是因為「想想」?

答案恐怕不是。作者指出《外交政策》是基於人類正面臨一個「恐懼壓倒理性」的時代危機,他們選出來的思想家,代表人類與生俱來的渴望,「對抗悲觀主義不向絕望投降、挑戰醜陋人性拒絕接受失敗」。而蔡英文獲選,是因為她敢「戳那頭熊」,不像其他人那樣,向中共kowtow,這是她的膽識與勇氣。
