一起聽英語 48 電影中的科學(xué)

想象一下如果宇宙中發(fā)生了大爆炸，而你正處于太空中，是否會聽到轟隆隆的爆炸聲呢?今天探討的就是電影中的科學(xué)。

Callum: Hello and welcome to 6 Minute English, I'm Callum Robertson and with me

today is William Kremer, hello William.

William: Hello Callum.

Callum: Today science in the movies. And we start with a question based on a scene

that will be familiar to many science-fiction fans. If you were in space and

there was a big explosion, what would you hear? Would the sound be:

a: louder than on Earth?

b: quieter than on Earth?

c: there be no sound at all?

William: I'm going to go for c: there's going to be no sound at all.

Callum: OK, we'll find out if you're right at the end of the programme.

Well there is science in many films, not just science-fiction films. For example

picture a scene in which there is a petrol station and there is a pool of petrol, or

gasoline, on the ground and a character in the film takes a long suck on his

cigarette and he throws it into the pool of petrol. In the movies, what happens

William?

William: Booooom

Callum: In the movies there is a great explosion and in real life, what happens?

William: Does it just go out?

Callum: Yes it does. Apparently – I haven't tried this and don't try this yourself but if

you do throw a lit cigarette into a pool of gasoline, it just puts the cigarette out

and it doesn't explode.

William: Very disappointing

Callum: Well it's just one example of how the laws of physics are slightly different in

the movies. But should films be more scientifically accurate? Sidney Perkowitz

is a scientist and author of the book Hollywood Science. He was interviewed

by the BBC on this topic and he was asked how much the science in films

should be based on fact and how much should be based on fantasy and

imagination. What's his opinion and does he think other scientists would agree

with him?

Professor Sidney Perkowitz

Ideally I think should have some of each mixed in, in good proportions. Not everyone would

agree with me. Some scientists would be tighter about it and say every bit of science has to be

wholly accurate. I wouldn't agree with that I think we could allow some flexibility.

Callum: So William, what was he saying there about science fact versus science fantasy?

William: Well he was saying that there should be some of both – of both reality and

fantasy – mixed in good proportions, which means in balance, so not too much

one way or the other way. But he did say that not everyone would agree with

him and that some scientists would want every single bit of science to be

correct. He says that he thinks they should allow some flexibility.

Callum: Flexibility?

William: Yes, 'flexibility', meaning not being fixed on one idea. So being able to 'bend'

to include different ideas.

Callum: Let's listen again.

Professor Sidney Perkowitz

Ideally I think should have some of each mixed in, in good proportions. Not everyone would

agree with me. Some scientists would be tighter about it and say every bit of science has to be

wholly accurate. I wouldn't agree with that I think we could allow some flexibility.

Callum: So can less than accurate science make for a good film? Professor Perkowitz

thinks so. He mentions one particular film – what was the film about and what

was wrong with the science?

Professor Sidney Perkowitz

One example that I like is a film that in fact got quite a bit of the science wrong but the basic

premise was good and it started a discussion. That was the film called 'The Day after

Tomorrow' which came out, I think, 2004. It's about global warming. It hyped-up the effects,

it made things happen more dramatically and more quickly than they really would but it also

started a conversation, so that to me is a great example of a film that had enough science in it

to have some impact on real world.

Callum: So William, what was the film about and what was wrong with the science?

William: The film he mentioned was 'The Day After Tomorrow' and he said it was about

global warming. And he said that although the basic premise was right, the

basic premise – which means the main idea or the main theory – so although

that was correct, the science was wrong in that things happened more quickly

and more dramatically than would really be possible.

And he also said that the effects of climate change were 'hyped-up' which

means they were over-exaggerated, over-dramatised. However despite this he

thought it was a good film because it started a discussion on important

environmental issues.

Callum: I have to say I really like that film and I always watch it when it's on. I know

some it is absolute nonsense but still, you know, I do enjoy it. Have you ever

seen it?

William: I've never seen it, no, I'd quite like to see it now.

Callum: Let's listen to Professor Perkowitz again.

Callum: Well that's just about all we have time for today. Before we go though, the

answer to this week's question, which was: if you were in space and there was

a big explosion, what would you hear? William you said:

William: I said c: no sound at all

Callum: You're absolutely right. Sound can't travel through a vacuum and space is a

vacuum. And on that note, it's time for us to leave you but do join us again next

time for another 6 Minute English. Goodbye.

William: Bye bye.
