Today we’re going to look at an important area of science, namely nanotechnology.

So what is it?

Nano means tiny, so it’s science and engineering on the scale of atoms and molecules.

The idea is that by controlling and rearranging atoms, you can literally create anything.

However, as we’ll see, the science of the small has some big implications affecting us in many ways.

There’s no doubt that nanotechnology promises so much for civilisation.

However, all new technologies have their teething problems.

And with nanotechnology, society often gets the wrong idea about its capabilities.

Numerous science-fiction books and movies have raised people's fears about nanotechnology - with scenarios such as inserting little nano-robots into your body that monitor everything you do without you realising it, or self-replicating nano-robots that eventually take over the world.

So how do we safeguard such a potentially powerful technology?

Some scientists recommend that nano-particles be treated as new chemicals with separate safety tests and clear labelling.

They believe that greater care should also be taken with nano-particles in laboratories and factories.

Others have called for a withdrawal of new nano products such as cosmetics and a temporary halt to many kinds of nanotech research.

But as far as I’m concerned there's a need to plough ahead with the discoveries and applications of nanotechnology.

I really believe that most scientists would welcome a way to guard against unethical uses of such technology.

We can’t go around thinking that all innovation is bad, all advancement is bad.

As with the debate about any new technology, it is how you use it that’s important.

So let’s look at some of its possible uses.

Thanks to nanotechnology, there could be a major breakthrough in the field of transportationwith the production of more durable metals.

These could be virtually unbreakable, lighter and much more pliable leading to planes that are 50 times lighter than at present.

Those same improved capabilities will dramatically reduce the cost of travelling into space making it more accessible to ordinary people and opening up a totally new holiday destination.

In terms of technology, the computer industry will be able to shrink computer parts down to minute sizes.

We need nanotechnology in order to create a new generation of computers that will work even faster and will have a million times more memory but will be about the size of a sugar cube.

Nanotechnology could also revolutionise the way that we generate power.

The cost of solar cells will be drastically reduced so harnessing this energy will be far more economical than at present.

But nanotechnology has much wider applications than this and could have an enormous impact on our environment.

For instance, tiny airborne nano-robots could be programmed to actually rebuild the ozone layer, which could lessen the impact of global warming on our planet.

That’s a pretty amazing thought, isn’t it?

On a more local scale, this new technology could help with the clean-up of environmental disasters as nanotechnology will allow us to remove oil and other contaminants from the water far more effectively.

And, if nanotechnology progresses as expected - as a sort of building block set of about 90 atoms - then you could build anything you wanted from the bottom up.

In terms of production, this means that you only use what you need and so there wouldn't be any waste.

The notion that you could create anything at all has major implications for our health.

It means that we’ll eventually be able to replicate anything.

This would have a phenomenal effect on our society.

In time it could even lead to the eradication of famine through the introduction of machines that produce food to feed the hungry.

But it’s in the area of medicine that nanotechnology may have its biggest impact.

How we detect disease will change as tiny biosensors are developed to analyse tests in minutes rather than days.

There’s even speculation nano-robots could be used to slow the ageing process, lengthening life expectancy.

As you can see, I’m very excited by the implications that could be available to us in the next few decades.

Just how long it’ll take, I honestly don't know.

이 영상으로 연습하는 방법

먼저 말하지 않고 영상을 끝까지 듣고 모르는 단어를 적어 둡니다.
보통 속도로 한 문장씩 섀도잉하고, 화자의 리듬과 맞을 때까지 반복합니다.
자신의 목소리를 녹음해 원본과 비교하고, robot, atom, hungry 같은 단어에 특히 주의합니다.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
