Ex 45 Read and discuss the following story. Speak on some other scientist.

Dmitri Ivanovich Mendeleyev was born on February 7, 1834 in Tobolsk. He came of a family of heroic pioneers. His grandfather was known as the publisher of the first newspaper in Siberia, the Irtish. His father was director of the local high school.

When Dmitri was still a boy his father died and his mother, who had made up her mind that Dmitri must get a good scientific education, moved first to Moscow, then to St. Petersburg where Mendeleyev entered the Pedagogical Institute. He worked hard and graduated at the head of the class. He was made professor of the University of St. Petersburg before he was 32. He wrote: "We need a double number of Newtons to discover the secrets of nature and to bring life into harmony with its laws."

Mendeleyev had spent twenty years studying the chemical elements. Before the end of the 19th century he surprised the world with his Periodic Law. He placed all the elements in order, starting with the lightest, hydrogen, and finishing his Table with uranium, the heaviest. In his Table he made places for more than 63 elements. But there were places in his Table which were still empty. Were they always to remain empty? Mendeleyev predicted several undiscovered elements.

The whole scientific world was thrilled.

At the time Mendeleyev died (1907) there were already 86 elements in the Periodic Table.

Mendeleyev was not only a scientist, he was also a social reformer. He hated the tyranny and oppression of Czarist Russia; he thought women to be equal to men in their struggle for work and education.

КАК БЫЛА ОТКРЫТА АНТАРКТИДА

16 июля 1819 года шлюпы «Мирный» и «Восток» вышли из Кронштадта. Они уходили в Антарктику на поиски неведомой Южной Земли, о которой знаменитый английский мореплаватель Джеймс Кук писал в своем дневнике, что такой земли нет.

Командиром шлюпа «Восток», а также начальником экспедиции был Ф. Ф Беллинсгаузен. Шлюпом «Мирный» командовал М. П. Лазарев.

Шлюпы шли по Атлантике* вниз. Далеко позади остались Лондон, Тенериф*, Рио-де-Жанейро, Южные острова*.

27 января 1820 года экспедиция пересекла Южный полярный круг. На следующий день продвижение экспедиции было остановлено стеной из льда. Так экспедицией Беллинсгаузена была открыта Антарктида. Было сделано одно из величайших географических открытий.

Семьсот пятьдесят один день длилась экспедиция. Было пройдено около ста тысяч километров. Всего было открыто, описано и нанесено на карту двадцать девять больших и малых островов.

Спустя год «Восток» и «Мирный» вышли из антарктических вод. Вышли там же, где и вошли, — в районе острова Южная Георгия*.
