Good morning Ladies and Gentlemen, fellow jury-members.
ŮʿǣǣίǣϺã

Thank you. 
лл

It is very exciting for me to be here to chair the jury for the 3rd 
Beijing Science Film Festival, and I would like to express my 
particular thanks to Zhang Yutai, the President, and to Zhou Guangzhao, 
the Honourable Chairman of the Festival.  Thank you for your kindness 
in inviting me.
ҵ˵ε챱ƼӰӽίϯеǳҪر

I have not been to Beijing for over 12 years, and it feels so different, 
so full of energy and drive.  I have been in the city less than 24 
hours, but I have been struck by the busy pace of modern life around me.
ұ12겻ˣҸо仯ܴ󣬵ܸ
в24СʱѾæµյִΧȾ

And you can see everywhere in that modern lifestyle that there is 
science at work.  We dont have to list all the examples: the cars, 
the buildings, the electronics, the medicine C and many, many more 
activities depend on the work of science.
ִ޴ܸܵѧáǲгеӣ
ҽҩԼܶѧöڵ

In fact nothing today remains untouched by the process of science.  
Try to think of something C anything, any activity C that has not 
been improved, changed, or simply better understood by scientific 
endeavour.  Put simply, science is everywhere.
ʵϣûκһǿѧġһЩ
飬ЩѧԸĽıǱõأ
˵ѧ޴ڣ

So today, perhaps more than at any other time in history, it is 
important that everyone has some understanding of science, and above 
all some understanding of the principles that underlie scientific 
thinking.  Because they need it in their everyday lives. 
ôÿ˵ѧҪǣѧ˼άԭҲ
ʷκʱ򶼸ҪΪճжҪ

Of course many people today, certainly in the West, do not realise 
that understanding science may help them.  Many fear science, and hold 
it responsible for some of societys ills. But when you sit down and 
talk to them, as we have recently done in some BBC audience research, 
and you show them the science in their lives C in their food, in 
their transport; or in their stereo headphones, or even their make-up 
C they all, all of them, have a moment of realisation of the 
importance of science and its benefits: a moment of enlightenment.

The late, great physicist Richard Feynman once expressed it beautifully, 
thus.  If you ask an artist to appreciate a rose, they will describe 
its form, its colour, the light dancing on the leaves waving in the 
breeze, the emotional impact of the scent, the romance and beauty of it.
ѹʵΰѧ¡ѧһλ
һõ壬ǽ״ɫ΢Ҷӯ
ˣǵУ

If you ask a scientist to do the same thing, he or she is likely to 
talk about the structure of the petals, the process of photosynthesis 
that harnesses the energy from the sun, the growth of cells in the stem, 
the pollen in the reproductive organs, the ecological balance with the 
insects and fungi that depend on it, the chemistry of the smell C the 
list could go on.
һѧͬ飬ܻܿὲĽṹ̫
ĹãϸֳеĻۣ桢֮
̬ƽ⣬ĻѧԭȵȣƵ⣡

And yet for the scientist it is still no less a rose C in all its 
romantic beauty.  Science only adds to your depth of understanding. It 
takes nothing away.
ڿѧ˵Ȼǵصصõ壬ӵȫ֮ѧֻ
˽⣬κζ

So we all have a job to do.  All of us in this room.  I believe that 
it is our role as science film and television programme makers to help 
people reach that moment of insight C to help them see the power of 
science, its underlying presence, and how it can only add to their 
appreciation and understanding of the wonder and beauty of the world 
around us.  We have to help them see that science is far from 
something to be afraid of, but instead is something that can help us 
all deal with the pressures of the modern world.

So how do we do that?  Well here I turn to Zhao Zhizhen, the Director 
of the Festival, but also the man who, as we all know, was the 
inspiration for the creation of the very first Beijing Festival in 2000.
ôǸôأ̸̸δ칫
ȫ֪ģҲ2000һ챱ƼӰӽڵķˡ

In advance of my visit, I did my homework.  I looked at all the 
stories of how Zhao Zhizhen became involved in science programming C 
many of you will know them already.  I saw a portrait of a man with a 
passion for science, and a passion for communicating science to others.
֮ǰЩ׼Ķйοʼ¿սĿ
Ĺ£ҲĺܶѾ֪ˡΪһԿѧȰ
ѧˡ

Zhao Zhizhen, I share your passion for science.  I too am passionate 
about communicating and popularising science. I too believe we need to 
care about ecology and the environment, as you do. We need to expose 
scientific fraud, as you do.  We need to counter pseudo-science, which 
is such a dangerous force in misusing the principles of science to 
make false claims.  We both know that.
ҺһԿѧȰҲǸռѧˡ
ҲҪ̬ͻһҪ¶ѧƭ֣
һǱαѧαѧһַǳΣյǴ
ÿѧԭƲʵ֮ʡ˶֪һ㡣

Also we need to make people aware of the history of science, and how 
it has come to underpin so much of our culture - which is one of my 
personal passions. 
ͬʱҲӦ˽ѧ̣Լ̵Ӱǵ
ĻȻҲҸ˵Ȥ֮һ

And by the way, we also both seem to like space science, and the 
planets.  
⣬ҲȰ̫տѧ

But of course it is not only Zhao Zhizhen and me.  We are just two.  
Everyone here in this hall is passionate about science. That is why 
you are here. And ultimately, that is at the heart of what we as 
science programme-makers have to do.  We must harness that passion, 
that belief in, and that love for, science.
Ȼⲻ˵¡ֻˡÿһλԿ
ѧȰҲǼһõԭҲΪƼĿ
µҵĺڡǱǶԿѧ飬Կѧ

After 25 or more years of making television programmes about science, 
I have come to realise that if you can reveal this passion to the 
audience then that is half the battle in getting them to engage in the 
subject.
25¿ƼӽĿľʶܹչʾ
Ĺڣôͻ°빦Ч

And seated here in front of me there is a huge amount of passion for 
explaining science; passion for investigating science; passion for 
telling stories about science; passion for revealing new science 
discoveries; passion for debating science; passion for delving into 
the past of science.
ǰһɾ޴飺Ϳѧоѧѧ£ʾѧ
֣ۿѧԼпѧ̵顣

So over the next three days, I think the juries are going to 
experience a lot of passion, and I expect there will be some heated 
discussions between my colleagues, as we try to reach the right 
decisions for the awards.  For it is going to be a difficult task.
δίǽܵ飬ڴҵͬн
չҵۣԱǶԸȷľΪһ޵

A year ago, I attended the World Congress of Science Producers in 
Paris.  This is an annual gathering, in a different city each year, 
where the best and the most committed of all the worlds television 
producers who specialise in science programmes gather to debate 
current issues, talk about new techniques and watch out for new talent 
and trends in the industry.   I hope one day that we may attend the 
Congress here.

μһһȵľۻᣬǶȫõĺڿƼӽĿ
Ƭһãŵչۣ̽¼עƼӽ˲
ϣһμӸôᡣ

Anyway, some of the delegates there were worrying that the popularity 
of science programmes was past its peak, but at the opening session I 
was simply amazed at the range of science programmes that are being 
made today: from studio shows for children, to full historical dramas. 
 Always with science at their heart. 
֮ȻǴδĳЩĿƼĿѹ߷ʱڣǴοĻ
ʽϣҾطֽ֮ĿƼĿݲĶͯĿ
ȫʽĿѧʷ֣ȫԿѧΪġ

And that growth in diversity is also reflected in the extraordinary 
range of entries to the Beijing festival, this year.  Some 66 
productions to be judged.  Now I havent seen the programmes yet, but 
the range of titles looks astonishing.  Everything from the Genius 
of Junk, through The Stench of Hell, and Sparrow Elegy, to 
Who Owns the Key to Your Life? (me, I thought!), and  
Transplanting Memories (which is what I increasingly need, as I 
get older!).

This remarkable diversity is going to make it very tough to choose the 
winners.  But it suggests to me that the science film and TV industry 
is in very good health, and that it is an exciting place to be.
ô÷ḻƬѡӮҽǷǳѵһ顣˵Ƽ

Above all it reflects your passionate belief in the importance of 
science in society.  Wherever you turn, science matters.

the next few days of hard work.
