Translate the text and retell it in English:
Newton, one of the greatest scientists of all times was born in 1642 in
the little village in Lincolnshire, England. His father was a farmer and died
before Newton was born. His mother was a clever woman whom he always
loved.
After the school, Newton studied mathematics at Cambridge
University and received his degree in 1665. Then the university was closed
because of the danger of plague and Newton went home for eighteen
months. It was most important period in his life when he made his three
great discoveries — the discoveries of the differential calculuses, of the
nature of white light, and of the law of gravitation.
These discoveries are still important for the modern science. Newton
had always been interested in the problems of light. Many people saw
colors of a rainbow but only Newton showed, by his experiments, that white
light consists of these colors.
It is interesting how he discovered the law gravitation. Once, as he sat
at the garden, his attention was drawn by the fall of an apple. Many people
saw such an usual thing before. But it was Newton who asked himself a
question: "Why does that apple fall perpendicularly to the ground? Why
doesn't it go sidewards or upwards?" The answer to this question was the
theory of gravitation, discovered by Newton.
Newton died at the age of 84, and was buried in Westminster Abbey,
where his monument stands today.
