3 . Barbara McClintock was one of the most important scientists of the 20th century. She made important discoveries about genes and chromosomes(染色体).
Barbara McClintock was born in 1902 in Hartford, Connecticut. Her family moved to the Brooklyn area of New York City in 1908. Barbara was an active child with interests in sports and music. She also developed an interest in science.
She studied science at Cornell University in Ithaca, New York. Barbara was among a small number of undergraduate students to receive training in genetics in 1921. Years later, she noted that few college students wanted to study genetics.
Barbara McClintock decided to study botany, the scientific study of plants, at Cornell University. She completed her undergraduate studies in 1923. McClintock decided to continue her education at Cornell. She completed the master’s degree in 1925. Two years later, she finished all her requirements for the doctorate degree.
McClintock stayed at Cornell after she completed her education. She taught students botany. The 1930s was not a good time to be a young scientist in the United States. The country was in the middle of the great economic depression. Millions of Americans were unemployed. Male scientists were offered jobs. But female geneticists were not much in demand.
An old friend from Cornell, Marcus Rhoades, invited McClintock to spend the summer of 1941 working at the Cold Spring Harbor Laboratory. It is a research center on Long Island, near New York City. McClintock started a temporary job with the genetics department. A short time later, she accepted a perpetual position in the laboratory and got continual incomes. This gave her the freedom to continue her research without repeatedly asking for financial aid.
By the 1970s, her discoveries had had an effect on everything from genetic engineering to cancer research. McClintock won the Nobel Prize for Physiology or Medicine in 1983 for her discovery of the ability of genes to change positions on chromosomes. She was the first American woman to win an unshared Nobel Prize.

5 . Alfred Nobel, the Swedish inventor and industrialist, was a man of many contrasts He was the son of a bankrupt, but became a millionaire; a scientist with a love of literature, an industrialist who managed to remain an idealist. He made a fortune but lived a very simple life, and although cheerful in company he was often sad in private. A lover of mankind, he never had a wife or family to love him; a patriotic son of his native land, he died alone on foreign soil. He invented a new explosive, dynamite, to improve the peacetime industries of mining and road building, but saw it was used as a weapon of war to kill and injure his fellow men. During his useful life he often felt he was useless: ''Alfred Nobel, '' he once wrote of himself, ''ought to have been put to death by a kind doctor as soon as, with a cry, he entered life. '' ''World-famous for his works he was never personally well-known, for throughout his life he avoided publicity. “I do not see, '' he once said, ''that I have deserved any fame and I have no taste for it, '' but since his death his name has brought fame and glory to others. He was born in Stockholm on October 21, 1833 but moved to Russia with his parents in 1842, where his father, Immanuel, made a strong position for himself in the engineering industry. Immanuel Nobel invented the landmine and made a lot of money from government orders for it during the Crimean War, but went bankrupt soon after.
Most of the family returned to Sweden in 1859, where Alfred rejoined them in 1863, beginning his own study of explosives in his father's laboratory. He had never been to school or university but had studied privately. And by the time he was twenty, he was a skillful chemist and excellent linguist, speaking Swedish, Russian, German, French and English. Like his father, Alfred Nobel was imaginative and inventive, but he had better luck in business and showed more financial sense. He was quick to see industrial openings for his scientific inventions and built up over 80 companies in 20 different countries. Indeed his greatness lay in his outstanding ability to combine the qualities of an original scientist with those of a forward-looking industrialist. But Nobel's main concern was never with making money or even with making scientific discoveries. Seldom happy, he was always searching for a meaning to life, and from his youth had taken a serious interest in literature and philosophy. Perhaps he could not find ordinary human love - he never married he came to care deeply about the whole of mankind. He was always generous to the poor: ''I'd rather take care of. the stomachs of the living than the glory of the dead in the form of stone materials, '' he once said. His greatest wish, however, was to see an end to wars, and thus peace between nations, and he spent much time and money working for this cause until his death in Italy in 1896. His famous will, in which he left money to provide prizes for outstanding work in Physics, Chemistry, Physiology, Medicine, Literature and Peace, is a memorial to his interests and ideals. And so, the man who felt he should have died at birth is remembered and respected long after his death.
