英國造了一枚很有意思的錢幣紀念霍金
UK Put a Black Hole on a 50p Coin to Honour Stephen Hawking, And It Looks Stunning
英國在50便士的硬幣上面鑄上了黑洞來紀念斯蒂芬·霍金，它看起來棒呆了。It's been a year since the renowned and profoundly influential physicist Stephen Hawking passed away, and the Royal Mint has honoured his legacy in the form of a new commemorative 50 pence coin.
舉世聞名而影響深遠的物理學家史蒂芬·霍金逝世已經一週年了，皇家鑄幣局發行一種新的50便士紀念幣來紀念他做出的貢獻。If you've ever been concerned that British currency doesn't feature enough astrophysical equations, we have good news.
如果你擔心過英國貨幣沒有給予天體物理方程足夠的重視，那我們現在有個好消息。
Although the collector's item, sold on the Royal Mint website, won't be released into circulation, the stunning coin displays the formula describing a black hole's entropy.
雖然這款收藏幣只在皇家鑄幣局官網上出售，不會投入使用、流通，但這枚炫酷的硬幣展示了計算黑洞熵的公式。Rather than featuring a portrait of the scientist himself, the designer went for something far more abstract, and yet something Stephen Hawking, who had a great sense of humour, would hopefully have approved of.
設計師沒有印科學家本人的肖像，而是轉向更爲抽象的公式，具有幽默感的史蒂芬·霍金本人應該會對此相當讚許。"I wanted to fit a big black hole on the tiny coin and wish he was still here chortling at the thought," engraver Edwina Ellis told the BBC.
雕刻家Edwina Ellis告訴英國BBC：“我想在這枚小硬幣上放一個大黑洞，我多希望他還活着，還能爲這個主意哈哈大笑。”In simple terms, it links the amount of disorder contained by a black hole with a physical feature of the hole itself: its area. Taken further, it means adding material to a black hole makes its surface expand.
簡單地說，這個公式將黑洞所包含的無序程度與黑洞本身的物理特徵（即其面積）聯繫起來。更進一步說，這意味着在黑洞中加入物質會使其表面膨脹。This also implies a way to make black holes less black through the emission of a weird kind of radiation, a finding that Hawking proudly counted as one of his landmark contributions to science.
這也意味着黑洞通過發射一種奇怪的輻射來減少質量，這是霍金引以爲傲的一個發現，被視爲對科學裏程碑式的貢獻之一。Amid swirling lines angled to inspire thoughts of space curving around an event horizon is Hawking's name below the Bekenstein-Hawking formula.
貝肯斯坦-霍金方程在上，霍金的名字在下，用迴旋的曲線按角度環繞成一個視界彎曲的空間，看起來就像是黑洞的邊界那扭曲的空間。The design certainly has his daughter Lucy's approval.
這個設計當然也得到了霍金女兒的同意。"It is a great privilege to be featured on a coin and I hope my father would be pleased to be alongside Sir Isaac Newton and Charles Darwin as scientists who have made it on to money," Lucy told the BBC.
Lucy對BBC說：“能出現在硬幣上是一種莫大的榮幸，我希望我的父親會因能和艾薩克·牛頓爵士和查爾斯·達爾文這些已經印在錢上的科學家們並肩而高興。”
