                                                    Albert Einstein (1879 – 1955)

         "See what I have for you, my boy. A mysterious box with a magic needle. Let's turn the box. Look! Still the needle
points only this way."
         Albert took the box and turned it one way, then the other. The needle always returned gently and pointed in the
same direction as before.
         "Papa, what makes the needle always point one and the same way?" the boy asked.
         "Well, you won't understand that. The magnetism of the Earth pulls it back."
         Albert took the compass to bed with him. It occupied all his thoughts for hours. His curiosity grew. He wanted to
know more.
       Albert Einstein was born in Germany on March 14, 1879. His unusual ability to
mathematics and physics began to show itself at a technical school in Zurich. At the age
of 21, after four years of university study, Albert Einstein got a job as a clerk at an
office. But already in 1905 he made revolutionary discoveries in science. He published
three papers. In the first he explained the photoelectric effect by means of Planck's
quantum theory. The second paper developed a mathematical theory of Brownian
motion. He presented his third paper on "Special Theory of Relativity" to a physical
journal. Einstein expressed his theory in the equation E=mc, roughly that energy equals
mass times the square of the speed of light.
         All over the world scientists read the work with great surprise. Few physicians understood its importance at that
time. Everybody wanted to know as much as possible about the author. In which university did he teach? In what laboratory
did he do his research?
         Albert Einstein was a very talented man, a great thinker. He had an ability to look at the world with eyes full of
wonder. All problems were new to him and he liked to solve them in his own way.
         Einstein's fame among scientists grew slowly but surely. For a few years he lived in where he worked as a
professor. When he came to Prague, he often told his students, "I shall always try to help you. If you have a problem, come
to me with it, we shall solve it together."
         He liked questions and answered them at once, for there were no simple or foolish questions for him. He spoke
much with his students about scientific problems and his new ideas. His advice to young students was, "Don't take easy
problems."
         Einstein continued his research. His unified field theory was the result of 35 years of intense work. He expressed it
in four equations where he combined the physical laws that control forces of light and energy with the mysterious force of
gravitation.
         In 1922 Einstein got the Nobel Prize in physics not for the theory of relativity but for a logical explanation of the
photoelectric effect.
         He gave all his life to the increase of human knowledge. His ideas produced revolution in the natural science of the
20th century.
