I want to build a billion tiny factories, models of each other, which are manufacturing simultaneously. . . The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too big. — Rich-

ard Feynman, Nobel Prize winner in physics

Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular selfassembly, from developing new materials with dimensions on the nanoscale to investigating whether we can directly control matter on the atomic scale.

When K. Eric Drexler popularized the word 'nanotechnology' in the 1980's, he was talking about building machines on the scale of molecules, a few nanometers wide — motors, robot arms, and even whole computers, far smaller than a cell. Drexler spent the next ten years describing and analyzing these incredible devices, and responding to accusations of science fiction. Meanwhile, mundane technology was developing the ability to build simple structures on a molecular scale. As nanotechnology became an accepted concept, the meaning of the word shifted to encompass the simpler kinds of nanometer-scale technology. The U.S. National Nanotechnology Initiative was created to fund this kind of nanotech: their definition includes anything smaller than 100 nanometers with novel properties.

There has been much debate on the future implications of nanotechnology. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in medicine, electronics, biomaterials and energy production. On the other hand, nanotechnology raises many of the same issues as with any introduction of new technology, including concerns about the toxicity and environmental impact of nanomaterials, and their potential effects on global economics, as well as speculation about various doomsday scenarios. Some people are afraid that it will result in a manufacturing revolu-

Text B. “Large Hadron Collider”

1. Read and translate the text.

Large Hadron Collider

The Large Hadron Collider (LHC) is a gigantic scientific instrument near Geneva, where it spans the border between Switzerland and France about 100 m underground. It is a particle accelerator used by physicists to study the smallest known particles – the fundamental building blocks of all things. It will revolu-

103

tionise our understanding, from the minuscule world deep within atoms to the vastness of the Universe.

Two beams of subatomic particles called 'hadrons' – either protons or lead ions – will travel in opposite directions inside the circular accelerator, gaining energy with every lap. Physicists will use the LHC to recreate the conditions just after the Big Bang, by colliding the two beams head-on at very high energy. Teams of physicists from around the world will analyse the particles created in the collisions using special detectors in a number of experiments dedicated to the LHC.

The LHC is exactly what its name suggests - a large collider of hadrons. Strictly, LHC refers to the collider; a machine that deserves to be labelled ‘large’, it not only weighs more than 38,000 tons, but runs for 27km in a circular tunnel 100 metres beneath the Swiss/French border at Geneva.

However, the collider is only one of three essential parts of the LHC project. The other two are:

1)the detectors, which sit in 4 huge chambers at points around the LHC tunnel

2)the GRID, which is a global network of computers and software essential to processing the data recorded by LHC’s detectors

There are many theories as to what will result from these collisions, but

what's for sure is that a brave new world of physics will emerge from the new accelerator, as knowledge in particle physics goes on to describe the workings of the Universe. For decades, the Standard Model of particle physics has served physicists well as a means of understanding the fundamental laws of Nature, but it does not tell the whole story. Only experimental data using the higher energies reached by the LHC can push knowledge forward, challenging those who seek confirmation of established knowledge, and those who dare to dream beyond the paradigm.

Text C. “Futurology”

1. Read and translate the text.

Futurology

If you could see your future, would you try to make it better? It’s safe to assume that we would all say “yes” to this question. Our only excuse in letting old patterns reoccur is a claim that we can't see the future with any degree of certainty, but is this claim true? Sometimes looking at terrible events we just want to exclaim, “How could they have not seen the future when it was so evident? What good is history if we cannot learn from its mistakes and plot a better course for the future?” These are some of the questions that futurology attempts to illuminate.

Futures is an interdisciplinary field, studying yesterday's and today's changes, and aggregating and analyzing both lay and professional strategies, and opinions with respect to tomorrow. It includes analyzing the sources, patterns, and causes of change and stability in the attempt to develop foresight and to map possible futures. Around the world the field is variously referred to as futures studies, strategic foresight, futurology, futuristics, futures thinking, futuring, etc. Futures studies (and one of its subdisciplines, strategic foresight) are the academic field's most commonly used terms in the English-speaking world.

Foresight may be the oldest term for the field. In a 1932 BBC broadcast the visionary author H.G. Wells called for the establishment of "Departments and Professors of Foresight," presaging the development of modern academic futures studies by approximately 40 years. Futurology is a term common in encyclopedias, though it used almost exclusively by nonpractitioners today, at least in the English-speaking world. Futurology is defined as the "study of the future." The term was coined by German professor Ossip K. Flechtheim in the mid1940s, who proposed it as a new branch of knowledge that would include a new science of probability. This term may have fallen from favor in recent decades because modern practitioners stress the importance of alternative and plural fu-

107

tures, rather than one monolithic future, and the limitations of prediction and probability, versus the creation of possible and preferable futures.

Futures studies does not generally focus on short term predictions such as interest rates over the next business cycle. Most strategic planning, which develops operational plans for preferred futures with time horizons of one to three years, is also not considered futures. But plans and strategies with longer time horizons that specifically attempt to anticipate possible future events are part of a major subdiscipline of futures studies called strategic foresight.

The futures field also excludes those who make future predictions through professed supernatural means. At the same time, it does seek to understand the models such groups use and the interpretations they give to these models.

Futurists use a diverse range of forecasting methods including causal layered analysis (CLA), environmental scanning, scenario method, future history, monitoring, backcasting (eco-history), back-view mirror analysis, cross-impact analysis, futures workshops, futures biographies, simulation and modelling, social network analysis, systems engineering, trend analysis, and some others.

Ready or not, here it comes. In the next 20 years, nano-technology will touch the life of nearly every person on the planet. The potential benefits are mind boggling and brain enhancing. But like many of the great advancements in earth's history, it is not without risk.

5. Read the following predictions made by futurists. Which of the predictions would you like or not like to come true? Why?

The technology already exists, so very soon all of us are going to use our voices to give instructions to computers.

In the next few years, we will be communicating with our friends around the world using life-sized video images on large screens in our living rooms.

By the year 2020, computers will already have become more efficient and powerful than the human brain both in terms of intelligence and the amount of information they can store.

By the year 2030, genetic engineering and nanotechnology will enable us to live for at least 150 years. Using nanotechnology, tiny, insect-like robots may be sent around our bodies to carry out repairs and keep us healthy.

By the middle of the century, computers, millions of times smarter than us, will have been developed. By this time, we will be linking our brains with 'ultra-smart' computers. A new species might have developed – 'Homo Cyberneticus'.

Bу the end of the century, we will have colonised our solar system and will be looking for ways to colonise deep space.

6. Work in pairs. Make predictions about each other in twenty years’ time. Say what you think about your partner’s predictions.

Example. A: I think that in 20 years’ time you’ll be working as a chief engineer of a huge industrial enterprise.

B: I certainly hope so!
