4、 do to improve science teaching at school?整理課件TextScience: fact or fiction?整理課件Science: fact or fiction?1 Students arent what they used to be. These days, it seems, some of them never even open a book. Such is the depressing picture painted by popular science writer Steve Jones in his book The Singl

5、e Helix, laying the finger of blame on modern communication systems. 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 outd

6、ated form of communication. Text整理課件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

7、simulation of a rocket journey through space: You can play tennis on board as the rocket speeds up or slows down. And there are cartoons to make even the most obscure scientific subjects accessible, and fun as well.Text整理課件3 But even these methods of generating interest have become conventional. Rat

8、her more radical is the proposal 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

9、the same time.Text整理課件4 A few examples 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

10、 and opposite. Since the Earth 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

11、few basic sums would show that 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整理課件5 So the film is fiction without the science. The same could be said of the 1986 film Aliens. In this film the crew sau

12、nter around the spaceship as if they 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 flyin

13、g colours. On board the spaceship a giant wheel rotates, generating centripetal force and giving the astronauts on board a sense of “up” and “down”.Text整理課件6The treatment of relativity in science fiction films is even more confusing. Take Star Trek: The Voyage Home (1987). As the spaceship revolves

14、round the sun, it gathers so much speed 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 baffle

15、d by the concept. It takes him a split second to fly round the earth anticlockwise to save Lois Lane, who has fallen victim to an earthquake. Jones: “Time is not like a car. It has no reverse gear.”Text整理課件7 Finally, what about those giant insects like the ones in Empire of the Ants, the 1977 film b

16、ased on a story by H. G. Wells? The problem is their lungs, or rather, the lack of them. Ants dont have lungs, so they get oxygen by absorbing it through the tissues of their bodies. The bigger the ant, the longer it would take to absorb the oxygen and their body parts would not be able to function

17、well. So an ant the size of a human would be more likely to be gasping for breath than biting off the head of a reckless teenager. Text整理課件Text科學(xué)：事實還是虛構(gòu)科學(xué)：事實還是虛構(gòu)? 1學(xué)生已今非昔比。如今，似乎有些學(xué)生從來就沒有翻開過書本。這是科普作家斯蒂夫瓊斯在其單螺旋線一書中描繪的令人沮喪的情景，他把批評的矛頭指向現(xiàn)代通信系統(tǒng)。信息即媒介；從前有書本，可是現(xiàn)在，瓊斯說：“媒介是，或者說似乎是，一切，但絕不是紙上印的一行行字?！痹S多學(xué)生就是不再習(xí)慣讀

18、書了書是老掉牙的溝通方式。整理課件Text2 那么怎樣使他們學(xué)習(xí)科學(xué)呢？好吧，你要是走進校園書店，就會找到辦法。那里有生物化學(xué)家的歌本，其中化學(xué)分子式被配上樂曲以便記憶。相對論是用電子游戲來解釋的，那是個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在上面打網(wǎng)球。還有卡通，它們使哪怕最艱澀的科學(xué)話題都變得有趣易懂。 整理課件Text3 可是就連這些激發(fā)興趣的方法也已變得老套了。更激進的方法是一個物理學(xué)教授提出來的：從科幻電影的錯誤中學(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，同時吸收一點科學(xué)知識。 整理課件Text4 有幾個例子可

19、以說明教授的想法。在地球著火之日（1961）中，兩顆同時爆炸的原子彈把地球推向太陽。可是這違反了牛頓的第三運動定律即，作用力和反作用力相等且方向相反。既然地球重達六千艾噸，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，那么這個炸彈的威力要比任何以往的炸彈都要大。但是，稍做運算就能說明，這樣一場爆炸除了會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）。整理課件Text5 所以，這部電影是沒有科學(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，宇航員們在宇宙飛

20、船中走來走去，就好像在地球上的家里一樣而實際上他們應(yīng)當(dāng)在無重力環(huán)境中漂浮才對。異形的制片人可能會在大學(xué)一年級的物理學(xué)考試中不及格，但是2001：太空漫游背后的智囊斯坦利庫布里克和亞瑟克拉克卻會在同樣的考試中以高分通過。宇宙飛船上有一巨大的輪子轉(zhuǎn)動著，產(chǎn)生向心力，并給船上的宇航員一種“起伏”感。整理課件Text6 科幻電影中對相對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：宇宙飛船圍繞太陽飛行，速度越來越快，最后竟然飛回到了歷史之中。但這是瞎編亂造，而不是相對論。正如瓊斯所說：“愛因斯坦說沒有什么比光速更快；但沒有說如果你跑得夠快，鐘表就會倒轉(zhuǎn)?！?就連超人（1978）也被

21、此概念所困惑。他在瞬間往逆時針方向繞地球一周去救地震受難者洛伊斯萊恩。瓊斯說：“時間不像汽車，它沒有倒擋?！?整理課件Text7 最后，1977年根據(jù)H.G.威爾斯的小說拍攝的螞蟻帝國里的那些巨型昆蟲又如何呢？問題在于它們的肺，或者說，它們根本沒有肺。螞蟻沒有肺，它們是通過身體組織吸收氧氣的。螞蟻越大，吸收氧氣的時間就越長這樣它們身體的各部件就不能良好地運作。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。整理課件Words & Phrases整理課件Words & Phrases整理課件depressing a. sth. that is depress
