Such is the depressing picture painted by popular science writer Steve Jones in his book The Single Helix, laying the fi

The message is the medium; once upon a time there were books, but now, Jones says, “the medium is, or so it seems, anything but lines of print on a page.” Many students are just not used to reading books anymore theyre such an outdated form of communica

6、tion. Text.2 So how do you get them to learn about science? Well, if you go into a campus bookstore you can find out. There are songbooks for biochemists, with chemical formulae set to music to make them easier to remember. Relativity is explained in a video game which is a simulation of a rocket jo

And there are cartoons to make even the most obscure scientific subjects accessible, and fun as well.Text.3 But even these methods of generating interest have become conventional. Rather more radical is the prop

8、osal which a physics professor has come up with to learn science from the mistakes in science fiction films. Some of the films may be dreadful, but they hide a lot of helpful messages. Students just have to sit back, relax, enjoy the film, and soak up a bit of science at the same time.Text.4 A few e

9、xamples will show what the professor has in mind. In The Day the Earth Caught Fire (1961), the earth is pushed towards the sun as a result of two simultaneous atomic explosions. But this contravenes Newtons Third Law of Motion namely, that action and reaction are equal and opposite. Since the Earth

10、weighs six thousand billion billion tons, a huge blast would be needed to push it into the right direction. Supposing it hurled a hundred million tons of rock and debris into space. This explosion would require a bomb far greater than any that has ever exploded. But a few basic sums would show that

11、such a blast, as well as killing every single inhabitant of the earth, would only shift the Earth about a quarter of an inch out of its orbit.Text.5 So the film is fiction without the science. The same could be said of the 1986 film Aliens. In this film the crew saunter around the spaceship as if th

12、ey were at home on earth whereas they should be floating, in a gravity-free environment. The producers of Aliens would fail a first year physics exam, but Stanley Kubrick and Arthur Clarke, the brains behind 2001: A Space Odyssey, would pass the same exam with flying colours.

14、ed that it moves backwards into history. But this is nonsense, not relativity. As Jones puts it, “Einstein said that nothing travels at more than the speed of light, not that the clocks will run the other way if you go fast enough.” Even Superman (1978) is baffled by the concept. It takes him a spli

It has no reverse gear.”Text.7 Finally, what about those giant insects like the ones in Empire of the Ants, the 1977 film based on a story by H. G. Wells? The prob

The bigger the ant, the longer it would take to absorb the oxygen and their body parts would not be able to function well. So an ant the size of a human woul

Text.Text科學(xué)：事實(shí)還是虛構(gòu)科學(xué)：事實(shí)還是虛構(gòu)? 1學(xué)生已今非昔比。如今，似乎有些學(xué)生從來(lái)就沒(méi)有翻開(kāi)過(guò)書(shū)本。這是科普作家斯蒂夫瓊斯在其單螺旋線(xiàn)一書(shū)中描繪的令人沮喪的情景，他把批評(píng)的矛頭指向現(xiàn)代通信系統(tǒng)。信息即媒介；從前有書(shū)本，可是現(xiàn)在，瓊斯說(shuō)：“媒介是，或者說(shuō)似乎是，一切，但絕不是紙上印的一行行字。”許多學(xué)生就是不再習(xí)慣讀書(shū)了書(shū)是老掉牙的溝通方式。.Text2 那么怎樣使他們學(xué)習(xí)科學(xué)呢？好吧，你要是走進(jìn)校園

18、書(shū)店，就會(huì)找到辦法。那里有生物化學(xué)家的歌本，其中化學(xué)分子式被配上樂(lè)曲以便記憶。相對(duì)論是用電子游戲來(lái)解釋的，那是個(gè)虛擬乘火箭在空間旅行的游戲：你可以在火箭加速或減速飛行時(shí)在上面打網(wǎng)球。還有卡通，它們使哪怕最艱澀的科學(xué)話(huà)題都變得有趣易懂。 .Text3 可是就連這些激發(fā)興趣的方法也已變得老套了。更激進(jìn)的方法是一個(gè)物理學(xué)教授提出來(lái)的：從科幻電影的錯(cuò)誤中學(xué)習(xí)科學(xué)。有些電影也許糟透了，但其中隱藏有大量有益的信息。學(xué)生只需舒舒服服地坐著、放松、欣賞電影，同時(shí)吸收一點(diǎn)科學(xué)知識(shí)。 .Text4 有幾個(gè)例子可以說(shuō)明教授的想法。在地球著火之日（1961）中，兩顆同時(shí)爆炸的原子彈把地球推向太陽(yáng)?？墒沁@違反了牛頓的第

19、三運(yùn)動(dòng)定律即，作用力和反作用力相等且方向相反。既然地球重達(dá)六千艾噸，那就需要特大的爆炸才能把它推入正確的方向。假設(shè)爆炸將一億噸巖石和碎渣 拋入宇宙，那么這個(gè)炸彈的威力要比任何以往的炸彈都要大。但是，稍做運(yùn)算就能說(shuō)明，這樣一場(chǎng)爆炸除了會(huì)把地球上的生物全部殺死之外，充其量也只能讓地球偏離軌道大約四分之一英寸。 注：地球的重量應(yīng)該是610的24次方千克（10的18次方叫艾）。.Text5 所以，這部電影是沒(méi)有科學(xué)含量的虛構(gòu)作品。1986年出品的電影異形也是同樣。在這部影片中，宇航員們?cè)谟钪骘w船中走來(lái)走去，就好像在地球上的家里一樣而實(shí)際上他們應(yīng)當(dāng)在無(wú)重力環(huán)境中漂浮才對(duì)。異形的制片人可能會(huì)在大學(xué)一年級(jí)的

20、物理學(xué)考試中不及格，但是2001：太空漫游背后的智囊斯坦利庫(kù)布里克和亞瑟克拉克卻會(huì)在同樣的考試中以高分通過(guò)。宇宙飛船上有一巨大的輪子轉(zhuǎn)動(dòng)著，產(chǎn)生向心力，并給船上的宇航員一種“起伏”感。.Text6 科幻電影中對(duì)相對(duì)論的處理更是令人摸不著頭腦。以星艦迷航：回家之旅（1987）為例：宇宙飛船圍繞太陽(yáng)飛行，速度越來(lái)越快，最后竟然飛回到了歷史之中。但這是瞎編亂造，而不是相對(duì)論。正如瓊斯所說(shuō)：“愛(ài)因斯坦說(shuō)沒(méi)有什么比光速更快；但沒(méi)有說(shuō)如果你跑得夠快，鐘表就會(huì)倒轉(zhuǎn)?！?就連超人（1978）也被此概念所困惑。他在瞬間往逆時(shí)針?lè)较蚶@地球一周去救地震受難者洛伊斯萊恩。瓊斯說(shuō)：“時(shí)間不像汽車(chē)，它沒(méi)有倒擋?！?.Te

21、xt7 最后，1977年根據(jù)H.G.威爾斯的小說(shuō)拍攝的螞蟻帝國(guó)里的那些巨型昆蟲(chóng)又如何呢？問(wèn)題在于它們的肺，或者說(shuō)，它們根本沒(méi)有肺。螞蟻沒(méi)有肺，它們是通過(guò)身體組織吸收氧氣的。螞蟻越大，吸收氧氣的時(shí)間就越長(zhǎng)這樣它們身體的各部件就不能良好地運(yùn)作。所以像人那么大的螞蟻更可能老是在大口喘氣，而不是把冒失少年的腦袋咬掉。.Words & Phrases.Words & Phrases.depressing a. sth. that is depressing makes you feel very unhappy and disappointed 令人沮喪的；令人喪氣的 e.g.1.
