Text A. D.I.Mendeleyev (1834-1907)

Dmitry Ivanovich Mendeleyev is a famous Russian chemist. He is best known for his development of the periodic table of the properties of the chemical elements. This table displays that elements’ properties are changed periodically when they are arranged according to atomic weight.

Mendeleyev was born in 1834 in Tobolsk, Siberia. He studied chemistry at the University of St.Petersburg, and in 1859 he was sent to study at the University of Heidelberg. Mendeleyev returned to St.Petersburg and became Professor of Chemistry at the Technical Institute in 1863. He became Professor of General Chemistry at the University of St.Petersburg in 1866. Mendeleyev was a well-known teacher, and, because there was no good textbook in chemistry at that time, he wrote the two-volume “Principles of Chemistry” which became a classic textbook in chemistry. In this book Mendeleyev tried to classify the elements according to their chemical properties. In 1869 he published his first version of his periodic table of elements. In 1871 he published an improved version of the periodic table, in which he left gaps for elements that were not known at that time. His table and theories were proved later when three predicted elements: gallium, germanium, and scandium were discovered.

Mendeleyev investigated the chemical theory of solution. He found that the best proportion of alcohol and water in vodka is 40 %. He also investigated the thermal expansion of liquids and the nature of petroleum.

In 1893 he became director of the Bureau of Weights and Measures in St.Petersburg and held this position until his death in 1907.

Questions:

What is the main principle of periodic table of elements? What was the reason of writing the textbook “Principles of Chemistry”?

Text B. Aeronautical and Aerospace Engineering

Aeronautics deals with the whole field of design, manufacture, maintenance, testing, and use of aircraft for both civil and military purposes. It involves the knowledge of aerodynamics, structural design, propulsion engines, navigation, communication, and other related areas.

Aerospace engineering is closely connected with aeronautics, but is concerned with the flight of vehicles in space, beyond the earth's atmosphere, and includes the study and development of rocket engines, artificial satellites, and spacecraft for the exploration of outer space.

Text C. Numerals

Numerals are sighs or symbols for graphic representation of numbers. The earliest forms of numerical notation were simply groups of straight lines, either vertical or horizontal, each line corresponding to the number 1. Such a system was inconvenient when dealing with large numbers.

Roman Numerals

The system of number symbols created by the Romans expresses all numbers from 1 to 1 000 000 with the help of seven symbols:

I = 1

V = 5

X = 10

L = 50

C = 100

D = 500

M = 1 000

Roman numerals are read torn left to right. The symbols are usually added together. For example: IV = 4; VI = 6; LX = 60; XL = 40; MMII = 2002; MCMLVII = 1957

A small bar placed over the numeral multipliers the numeral by 1000.

Thus, theoretically, it is possible, by using an infinite number of bars, to express the umbers from 1 to infinity. In practice, however, one bar is usually used; two are rarely used, and more than two are almost never used. Roman numerals are still used day, more than 2000 years after their introduction. The Roman system's only drawback is that it is not suitable for rapid written calculations.
