ALBERT EINSTEIN
Albert Einstein was born in Ulm, Germany, in 1879. He was a quiet child who spent
much of his time alone. He was slow to talk and had difficulty learning to read. Albert did
not like school. The German schools of that time were not pleasant. Students could not
ask questions. Albert said he felt as if he were in prison.
From the time he was a boy, Albert Einstein had performed what he called "thought
experiments" to test his ideas. He used his mind as a laboratory. By 1905, he had
formed his ideas into theories that he published.
In one paper he said that light travels both in waves and in particles, called photons.
This idea is an important part of what is called the quantum theory.
Another paper was about the motion of small particles suspended in a liquid or gas. It
confirmed the atomic theory of matter.
The most important of Albert Einstein's theories published that year became known as
his "Special Theory of Relativity." He said the speed of light is always the same --
almost three hundred thousand kilometers a second. Where the light is coming from or
who is measuring it does not change the speed. However, he said, time can change.
And mass can change. And length can change. They depend on where a person is in
relation to an object or an event.
Ten years after his paper on the special theory of relativity, Albert Einstein finished work
on another theory. It described what he called his "General Theory of Relativity." It
expanded his special theory to include the motion of objects that are gaining speed.
This theory offered new ideas about gravity and the close relationship between matter
and energy. It built on the ideas about mass he had expressed in 1905.
In 1921, he won the Nobel Prize in Physics. It was given to him, not for his theories of
relativity, but for his discovery of the law of the photoelectric effect. This scientific law
explained how and why some metals give off electrons after light falls on their surfaces.
The discovery led to the development of modern electronics, including radio and
television.
Albert Einstein taught in Switzerland and Germany. He left Germany when Adolph Hitler
came to power in 1933. He moved to the United States to continue his research. He
worked at the Institute for Advanced Study in Princeton, New Jersey. Einstein became a
citizen of the United States in 1940.
Einstein was a famous man, but you would not have known that by looking at him. His
white hair was long and wild. He wore old clothes. He showed an inner joy when he was
playing his violin or talking about his work. Students and friends said he had a way of
explaining difficult ideas using images that were easy to understand.
Albert Einstein died in 1955. He was seventy-six years old

MICHAEL FARADAY
One of the great names in the history of man’s work in electricity is that of Michael
Faraday. He was born in a small village near London on September 22, 1791 in a poor
family. His father, a blacksmith, could feed his family with difficulty, and could not even
dream of an education for his boy.
As a boy Michael did not have much schooling. He had to work, and he had to learn a
trade. So in 1804, when he was thirteen, he went to work in a bookbinder’s shop.
He lived among books. Some of the scientific works which passed through his hands
aroused his interest in science and he started to read. The boy could not read every
book in the shop because he was busy and had not much time. He began to take home
the books which he liked best.
Once he read across an article on electricity. When Faraday began to read it he knew
nothing of the subject, but it struck his imagination. Soon his chief interest was in science, and especially in electricity and chemistry. He read as much as he could on these
subjects. He made careful notes from the books that interested him most.
To learn a science well it is necessary not only to read, but to experiment as well. Like
all true scientists, Faraday wanted to make experiments. He had very little money, but
he saved his few pennies and bought a cheap and simple apparatus and some
materials. The more he studied, the more interested he became. Lectures on scientific
subjects were at that time being given in London. Faraday wanted to go to these
lectures, but he had to pay a shilling for this and at first he could not go. He told his
brother about his difficulty. Although his brother was a working man in London and not
at all rich himself he gave Michael the shilling.
For more than five years he studied electricity and various sciences, and then he
himself began to teach. Faraday’s scientific interests were varied. He made a new kind
of steel and a new kind of glass. He studied flying. He did many kinds of work, and he
did most of it alone. He was of those people who liked to do everything themselves.
Faraday had not much time for pleasure. He drew and sang, and he took his wife to the
river sometimes. But he often worked fourteen hours a day. He began to get work from
other people who had heard of his cleverness as a scientist. Men who wanted to know
the answers to scientific questions asked him to make experiments to find out the truth.
Because of this work he could not do his own research in electricity. Time was his
enemy, as it is the enemy of many hard-working men. He always had something to do
for other people, and his own research progressed slowly. However, when he found that
such work took too much of his time, he decided to give all his attention to scientific
research.
During his lifetime, Faraday made more than two thousand difficult experiments and
made countless valuable discoveries in chemistry and physics. The generation of
electricity from magnetism is one of them.
This was the beginning of all the great machines that make our electricity today. They
light and heat our houses; they make our radio-sets work; they give the necessary
power to drive our electric trains. It was a way of changing one form of power (perhaps
from coal or from a waterfall) into another. It was the beginning of the electrical age,
which has changed the face of the earth.

CHARLES DARWIN
The famous naturalist and thinker, Charles Darwin, was born on February 12, 1809.
Charles’ father was a well-known physician, a Fellow of the Royal Society and the son
of a still greater physician, poet and scientist—Erasmus Darwin. Charles’ father hoped
that his son also would become a doctor.
As a boy, Charles liked to go rat-hunting with the dogs or to go out shooting. He walked
in the fields and woods observing nature and comparing his observations with everything he had read in natural science books. He was also fond of collecting. He collected
everything—shells, birds’ eggs (he never destroyed the nests and always took only one
egg for his collection), minerals, even leaves.
At sixteen Charles was sent to Edinburgh University to become a doctor. He had no
interest necessary for medicine and classical languages. But he was interested in the
natural history. At the end of two years Charles was still not interested in medicine and
his father began to think that the only thing to do was to make a parson of him. So he
was sent to Cambridge to work for his degree. Once a year, before his examinations,
Charles learnt his theology textbooks by heart and thus passed from one course to the
next. What he liked most of all at Cambridge was entomology and botany. At the
university he was one of a group of students who were very fond of hunting and sports.
In the spring of 1831 Charles took his degree but he refused to become a parson. He
decided to take part in the expedition to South America which lasted five years. He saw
many new plants and animals, all of the greatest interest to him. But one thing puzzled
him more and more. Like most people in those days, he thought that each species had
been created thousands of years before and had never changed. But as he went from
one part of South America to another he saw that many different species of plants and
animals and the fossils in some ways were very much alike. Was it possible that
species did change?
Darwin gradually became convinced that plants and living organisms really changed
and so did their surroundings. This was caused by the struggle for existence which went
on all the time; as a result of adaptability, new organs develop and one kind of species
changes into another. At last, in 1859, Darwin finished his book The Origin of Species
by Means of Natural Selection. It caused a sensation. Darwin was violently attacked by
bishops, politicians, even some scientists. Copies of the book were burned by people
who objected to the idea that men were descended from apes. But later more and more
scientists agreed with Darwin and began to support him. In 1871 he published another
book—The Descent of Man, which became almost as famous as The Origin of Species.
In this book he explained why he thought that mankind and the anthropoid apes, like the
orangutan, chimpanzee and gorilla, had the common ancestry.
Darwin continued his careful research until his sudden death in 1882. He was buried in
Westminster Abbey, near Newton’s grave.
Many outstanding scientists all over the world have applied Darwin’s teaching
successfully, but the greatest contribution in spreading and developing Darwinism was
made by such Russian scientists as K. A. Timiryazev. I. I. Mechnikov, I. M. Sechenov
and, later, I. P. Pavlov and I. V. Michurin
