Renowned British physicist Stephen Hawking, who sought to explain some of the most complicated questions of life while himself working diligently under the shadow of a likely premature death throughout his life, died at 76 at his home in Cambridge, the UK, on Wednesday morning.
Hawking’s formidable mind ceaselessly probed the very limits of human understanding both in the vastness of space and in the bizarre sub-molecular world of quantum mechanics, which explains how the smallest particles in the universe function and through its theoretical elaboration, according to Hawking, could predict what happens at the beginning and end of time.
By bringing together the theory of relativity, which explores the nature of space and time, and quantum theory, Hawking focused in his academic works on explaining the creation of the universe and how it is governed.

In 1974, Hawking was admitted to Britain’s most prestigious scientific body, the Royal Society, and became one of its youngest fellows at the age of 32. Five years later, Hawking moved from Oxford University to Cambridge University to study further theoretical astronomy and cosmology. Cambridge University appointed him as Lucasian Professor of Mathematics, a prestigious post of which the previous holders include Newton.
Throughout his life, Hawking worked on studies ranging from the origins of the universe to the tantalizing prospect of time travel to the mysteries of space’s all-consuming black holes.
But the power of his intellect contrasted cruelly with the weakness of his body, ravaged by the wasting motor neurone disease he contracted at the age of 21.
Hawking was confined for most of his life to a wheelchair. As his condition worsened, he had to resort to speaking through a voice synthesizer and communicating by moving his eyebrows. The disease spurred him to work harder but also contributed to the collapse of his two marriages, he wrote in a 2013 memoir My Brief History.
In the book he related how he was first diagnosed: “I felt it was very unfair — why should this happen to me,” he wrote. “At the time, I thought my life was over and that I would never realize the potential I felt I had. But now, 50 years later, I can be quietly satisfied with my life.”
Hawking shot to international fame after the 1988 publication of A Brief History of Time, one of the most complex books ever to achieve mass appeal, which stayed on the Sunday Times bestseller list for no fewer than 237 weeks. He said he wrote the book to convey his own excitement over recent discoveries about the universe.
“My original aim was to write a book that would sell on airport bookstalls,” he told reporters at the time. “In order to make sure it was understandable I tried the book out on my nurses. I think they understood most of it.”

知名的英國物理學家史蒂芬·霍金,週三早上在英國劍橋的家中過世,享壽七十六歲。終其一生,霍金試圖解開最為複雜艱深的生命之謎,自己卻同時面臨著英年早逝的可能,一輩子在死亡的陰影下孜孜矻矻地從事研究。
霍金以令人敬畏的卓越才智,不斷探索著人類理解程度的最極限,範圍大至廣闊無垠的宇宙,小至量子力學中奇異的次分子世界。量子力學理論解釋了宇宙中最小粒子的運作模式,因此他認為,推演這個理論,將能預測時間在最初的起始點與終點各會發生什麼現象。
藉著結合量子力學以及探討空間與時間關係的廣義相對論,霍金在學術著述中聚焦於對宇宙起源以及運行規則提出解釋。
一九七四年,霍金以三十二歲之齡當選英國皇家學會院士,成為英國聲譽最為崇高的科學研究機構中最年輕的研究者之一。五年之後,他從牛津大學遷往劍橋大學,以進一步深入研究理論天文學以及宇宙科學。翌年,霍金獲劍橋大學授予盧卡斯數學教授的頭銜,該席位是物理學者的最高榮譽,獲頒此頭銜的歷任教授還包括牛頓。
霍金畢生的研究領域包含探討宇宙的起源,廣而擴及到誘人的時間旅行可能性,乃至於在太空中吞噬一切的黑洞之謎。
只是,霍金的非凡才智卻和身體上的衰弱形成殘酷的對比。二十一歲時,他被診斷出罹患運動神經元疾病,從此飽受病痛折磨,身體逐漸衰弱。
霍金大半輩子的行動都受輪椅所限制。隨著病情惡化,他被迫仰賴語音合成器來說話,並且藉由眉毛動作來進行溝通。他在二○一三年出版的回憶錄《我的簡史》中表示,這個惡疾驅使他更戮力從事學術研究,卻也造成兩次婚姻的失敗。
在回憶錄中,霍金提及當年第一次被診斷出罹病的感受:「我感覺這非常不公平──為什麼這疾病要發生在我的身上」。他寫道:「那時,我以為我的生命就此結束,不會再有機會實現我自認擁有的潛能。不過,從五十年後的今天看來,可以說我已經對生命感到相當滿足。」
一九八八年出版的《時間簡史》,讓霍金瞬間獲得國際間的崇高聲望。《時間簡史》可說是廣獲大眾青睞的書中最為艱澀難懂的一本,卻在《星期日泰晤士報》的暢銷書排行榜上一待就是兩百三十七週。霍金說,他寫這本書的目的其實是想傳達近年來關於宇宙的新發現對自己帶來的興奮感。
「我原本的目標是想寫一本會被放在機場書架上賣的那種暢銷書。」霍金那時這麼跟記者解釋。「為了確定這本書可以讓人看得懂,我讓照顧我的護理師們都試讀過,我想他們能夠了解書中絕大部分的內容。」

Historians are rethinking the way the Holocaust is being presented in museums as the world marks the 80th anniversary of the liberation of the last Nazi concentration camps this month. Shocking images of the mass killings of Jews were “used massively at the end of World War II to show the violence of the Nazis,” historian Tal Bruttmann, a specialist on the Holocaust, told AFP. But in doing so “we kind of lost sight of the fact that is not normal to show” such graphic scenes of mass murder, of people being humiliated and dehumanized, he said. Up to this
When people listen to music today, they typically use streaming services like YouTube or Spotify. However, traditional formats like vinyl records have regained popularity in recent times. Vinyl records are circular discs that store music in grooves on their surfaces and are played on a turntable. As the turntable’s needle runs along these grooves, it picks up vibrations and translates them into sound. The history of vinyl records dates back to the late 1800s, but material and technological challenges delayed mass production until the 1950s. Despite early versions having short playtimes and poor sound quality, vinyl records introduced a new era
A: Brazilian jiu-jitsu, known as “BJJ,” has become more and more popular. Even Hollywood stars like Halle Berry and Tom Hardy are obsessed with it. B: Some Asian stars, such as Taiwanese actor Eddie Peng and South Korean actor Lee Joon-gi, have also practiced this martial art. A: BJJ is not just a martial art, but also a combat sport. B: I’ve always wanted to try it, but I’m worried about getting injured. A: Diana Wang, a US doctor of physical therapy, is holding a BJJ seminar at PMA Brazilian Jiu-jitsu in Taipei Friday night. Let’s go check out how we
A: Actually, Brazilian jiu-jitsu is particularly good for small people like you. B: Really? How so? A: According to Diana Wang, a US doctor of physical therapy, the BJJ’s purpose is to help smaller, weaker people defend themselves by using various techniques, such as leverage. B: That sounds interesting. What time does Dr Wang’s BJJ seminar begin tonight? A: The event is scheduled for 7:30pm at PMA Brazilian Jiu-jitsu in Taipei. Admission is free, but donations are welcome. A: 其實你的個子比較小,很適合練巴西柔術呢。 B: 真的嗎?為什麼? A: 據美國理療醫師王幼瑞博士說,巴西柔術的概念是讓弱小的人,也能利用槓桿作用等技巧防身。 B: 真有趣,王醫師的巴柔研討會幾點開始? A: 今晚7點半在「台北巴柔運動館」,免費入場自由樂捐唷!
