6.4 Speak on your field of science.

6.5 Read the dialogue in pairs and then learn it:

A: Hello, Pete!

B: Hello, Ann. What are you reading?

A: I'm reading the book "Flora of the World". Haven't you read it? B: No, I haven't.

A: I have learned a lot of interesting things from this book. For example, 1 know that there are more than 350.000 species of plants in the world, B: It is not easy to calculate those species, is it?

A: I think so. By the way, do you know the difference between plants and animals?

В: Certainly. They look absolutely different.

A: Oh, no. Now I see you don't know that difference. Listen, plants make their own food and animals do not. They eat plants or other animals that eat plants. Isn't it interesting?

В: Yes, really, it's very interesting and very simple. Now I see the difference between them.

A: Good for you. See you tomorrow!

В: Bye-bye.

6.6 Complete the dialogues:

A: Hello, Kate. I haven't seen you for ages. Where have you been?

K: ...

A: When did you come back to Rostov?

K: ...

A: But if you returned last Sunday, why didn't you attend the lecture on biochemistry on Monday. By the way, it was delivered by a Moscow University Prof. W. The lecture was very interesting.

K: ...

A: It's nice to see you again. See you tomorrow at the university.

K: ...

6. 8 Read the text and speak on your field of science "Physics": Physics

The word "physics" has its origins in the Greek word "pheusis" meaning nature.

Physics is a broad science about nature. Nature consists of a number of objects. Any object (a pencil, a stone, a drop of water, sand, etc. ) is called a physical body or a body. All bodies consist of matter. Steel, copper, rubber, water, air and a stone are some examples of matter. Various changes are taking place within them. All changes which occur in a physical body are known as phenomena. The melting of ice, the boiling of water, the falling of a stone, the heating of a wire by an electric current, wind, lightning — all these are different phenomena.

Physics studies various natural phenomena: mechanical motion, heat, sound, electricity, magnetism, light, etc. It also determines exact relation between physical phenomena. Physics is divided into a number of different fields: mechanics, acoustics, optics, thermodynamics, astrophysics, radio physics, nuclear physics, the physics of solids and others.

Physics can be divided into two great branches: experimental physics and theoretical physics. Experimental physics is the science of making observations and devising experiments. On the basis of experimental facts theoretical physics formulates laws and predicts the behavior of natural phenomena. Every physical law is based on experiments.

In the Physics faculty students study optical spectroscopy, х-ray spectroscopy, astrophysics, chemical physics, microwave electronics, quantum radio physics, the physics of the ionosphere and wave propagation, the physics of thin films and many others.

Physics is one of the main sciences about nature.
