Exercise 6

R1JWmCq4ix73w

Type in the missing letters to form nouns connected with the aim of the research carried out at CERN. The first letter of each noun is provided. Mind the spelling of the words you type in. The main type of experiments carried out at CERN is the collision of 1. hTu uzupełnij in the Large Hadron Collider. The data gathered in these experiments allows scientists to progress in their understanding of 2. pTu uzupełnij physics. For example, they can recreate the conditions of the early 3. uTu uzupełnij and explore how it was created. Some people fear that these tests could lead to a creation of black 4. hTu uzupełnij that would be dangerous to the surroundings. However, experts explain that the LHC won't do anything that the cosmic 5. rTu uzupełnij don't do, and these rays do not create black holes.

Exercise 7

You are creating a leaflet for educational trips visiting the CERN facility in Switzerland. Writing the text of the leaflet, focus on the things that visitors will see on the trip, what they can do, and what they mustn’t do. Write three sentences on each of these things.

Visiting CERN

Welcome to CERN, the home of the Large Hadron Collider. Upon your visit to the facility, you will be able to see many interesting things:

a huge, circular tunnel built completely underground.
experimental tubes filled with liquid helium.
powerful magnets that accelerate the particles to great speeds.

During your visit, you will be able to

travel 50‑175 metres down, in a special lift for visitors.
look inside the experimental tubes on display.
watch a video presentation of some experiments carried out at the facility.

For your comfort and safety, remember a few things:

Never leave your group and stay under your guide’s supervision at all times.
If you suffer from claustrophobia, inform the guide before the trip.
Under no circumstances are you allowed to touch any tubes and devices without your guide’s permission.

Exercise 8

You have recently read a text about the experimental CERN facility. In an email to a friend from England:

describe the location of the LHC;
explain the way the facility was structured;
discuss the experiments that are carried out there;
mention one fear that some people face in relation to the LHC and give your opinion about it.

Your answer should be 100–150 words long.

Dear Karen,

I have recently read about the Large Hadron Collider in Switzerland. I find the facility amazing and I would like to visit it one day.

The research facility is located at the Swiss‑French border, near Geneva. After visiting the LHC, you could visit the beautiful Swiss mountains!

One of the amazing features of the LHC is that it was built underground. It consists of two 27‑kilometre long tunnels, so visitng them can be a true adventure.

The experiments carried out in LHC involve accelerating hadrons with the use of powerful electromagnets. After that, they are made to collide with great energy. These experiments help scientists understand the nature of space and time better.

Some people are afraid that these experiments could create black holes. However, I disagree, because cosmic rays similar to those created in LHC occur in nature, and they don’t cause any problems.

Best wishes,

XYZ
