In 1970, American magician Rick Johnsson theorized that when magic tricks seem too perfect, audiences are less impressed and can easily figure out their secrets. Researchers at the University of London tested this theory, publishing their findings in PeerJ journal on May 30. 1970年，美國魔術師瑞克·約翰遜提出了這樣一個理論：魔術看起來太完美時，觀眾反而沒那么動容了，而且很容易就能破解魔術的秘密。倫敦大學的研究人員測試了這一理論，并于5月30日在《同行界》期刊上發表了研究結果。 They found viewers preferred “perfect” tricks to flawed ones. But consistent with the theory, viewers had an easier time understanding how these tricks were performed. 研究人員發現，比起有瑕疵的魔術，觀眾更喜歡“完美”的魔術。但與約翰遜理論一致的是，此時觀眾更容易理解這些魔術是如何表演的。 Johnsson knew in the 20th century few people believed magicians had supernatural powers. They knew there is a rational explanation for magic, and it’s often science. 約翰遜深知，在20世紀，很少有人相信魔術師擁有超自然的力量，觀眾知道魔術有一個合理的解釋，那往往就是科學。 What’s the science behind popular magic tricks? Website ScienceABC reveals their secrets. Let’s take a look. 廣受歡迎的魔術背后，隱藏著什么科學原理？科學ABC網站揭露了而這些魔術的秘密。讓我們一起來看看吧。 Levitating objects 空中飄物 Another popular trick is making objects levitate, with smaller objects being especially easy to “fly”. To the viewer, the levitating object may seem to defy gravity, but there’s a simple explanation – quantum physics. 一大熱門魔術是讓物體懸浮，小型物體尤其容易“飛起來”。在觀眾看來，這個懸浮的物體似乎是在對抗重力，但這個現象有著簡單的原理——量子力學。 Called quantum or magnetic levitation, the trick involves magnets and freezing cold temperatures. Magicians coat an object in a layer of magnetic paint and place it on top of a superconductor cooled by liquid nitrogen. The opposing forces cause the object to float above the superconductor. 這種把戲名叫量子懸浮或磁懸浮，過程涉及到磁鐵和極低的溫度。魔術師給某個物體涂上一層磁性涂料，然后把物體放在用液氮冷卻的超導體上。相對的力會令物體浮在超導體上方。 Vanishing liquids 液體消失 Many magicians can make liquids disappear. The explanation is simple – chemistry. 許多魔術師能讓液體消失。這種魔術的原理很簡單——化學。 Sodium polyacrylate, also known as “waterlock”, is a chemical compound that can absorb liquids. It’s used in everyday products such as baby diapers. What’s magical about this polymer is it can absorb 100 to 1000 times its mass in liquid. 聚丙烯酸鈉，又名“水閘”，是一種能夠吸收液體的化合物，常被應用于嬰兒尿布等日用品。這種化合物的神奇之處在于，其可吸收自身質量100到1000倍的液體。 When a magician pours water into a cup lined with sodium polyacrylate, the water is quickly absorbed. 魔術師把水倒進內襯有聚丙烯酸鈉的杯子里，水就飛速吸收了。 Burning paper 紙張燃燒 Another interesting trick is when magicians set paper alight, it remains intact. Magicians can even use money in this trick. However, there’s a scientific explanation – chemistry! 還有一個有趣的魔術：魔術師把紙點燃，紙張卻仍然完好無損。魔術師甚至可以用錢來變這個魔術。然而，這種現象有一個科學原理——化學！ The item is dipped in a mixture of alcohol and water before the trick. When it’s lit on fire, the alcohol covering the paper begins to burn. Alcohol burns and evaporates at a much lower temperature than water, so the water protects the paper from burning. 變魔術前，魔術師把紙張等物體浸入酒精和水的混合物中。紙張一旦點燃，覆蓋在紙上的酒精就會開始燃燒。酒精燃燒和蒸發的溫度比水低得多，所以水會起保護作用，紙張就不會燃燒。 以上文章內容選自《21世紀學生英文報》高一875期 Unitrans世聯翻譯公司在您身邊,離您近的翻譯公司,心貼心的專業服務,專業的全球語言翻譯與信息解決方案供應商,專業翻譯機構品牌。無論在本地,國內還是海外,我們的專業、星級體貼服務，為您的事業加速！專業翻譯公司,北京翻譯公司,上海翻譯公司,英文翻譯,日文翻譯,韓語翻譯,翻譯公司排行榜,翻譯公司收費價格表,翻譯公司收費標準,翻譯公司北京,翻譯公司上海。
