The light in a laser is reflected by the mirror ________. UNIT 3 ASTRONOMICAL CAPITAL OF THE WORLD. Two great observatories, Greenwich and Pulkovo, occupy a leading place among the observatories of the world. Some scientists call Pulkovo the astronomical capital of the world. Pulkovo is situated in a hilly area some kilometres from Leningrad. You can’t get to Pulkovo by train – when the railway was being built the astronomers specially asked that it should be kept several kilometres away so that there should be no vibration to affect the sensitive instruments. The work started in 1839, when the observatory was opened, is being continued now. This is the eternal work of astronomers – to define the precise co-ordinates of the stars, to find out the exact “addresses” of heavenly bodies. Today the scientists also conduct a time service, study activity of the Sun, follow the flights of the Earth sputniks and calculate their orbits. The scientists of the observatory have made a valuable contribution to the study of the cosmos by observing artificial Earth satellites, man-made moons. The study of their orbits is very important for the flights of manned space-ships. The Pulkovo observatory has a radio-astronomy department equipped with modern apparatus. The big radio-telescope installed there is stronger than any other telescope in the world. With the help of this powerful device the scientists of the Pulkovo observatory carry out a number of observatories of Venus, Jupiter and other planets. The astronomers have obtained extremely surprising results due to radio-astronomical observation. By means of the radio-telescope some remarkable studies of the surface of the Sun and of solar
Look at the picture! Here is our chemical laboratory. It occupies a large. room which is furnished with many long tables or benches 2 as they are called. It is at these benches that experiments are usually done. There are a lot of things on the first bench. Nearly in the middle there stands a Bunsen burner 3 with a flask over it. During an experiment the Bunsen burner is connected with the main gas line by a rubber tube. The flame of the burner is being regulated by means of a tap. The flask is fixed to the ring-stand. If some solution is boiling in the flask, the steam is coming out of it. At the side of the bench there is a sink with two taps for cold and hot water. At the foot of the bench on the left-hand side there are two shelves with a few bottles on them. They contain chemical substances: solids and liquids. Some of the liquids are colourless and odourless, while others possess different colours and odours. On the right-hand side there stands a rack with twelve test-tubes in it. On the wall above the bench one can see the Periodic Table of Elements. In the cupboard on the left you can see flasks of different shapes and sizes, different kinds of glass tubes, condensers, filters, and so on, that is,4 things without which no chemical experiment can be done. A student in white overall, Barbara, is preparing for an experiment at her bench. She is to get a new compound. Barbara is measuring some liquid in the measuring-glass. When the liquid is measured it is poured into a special vessel and is mixed with water. From time to time
