Amazing story about the boy Loew
A story worth knowing to all of us.
In one school in Moscow, the boy stopped attending classes. A week does not go, two ... Lev did not have a phone, and the classmates, on the advice of the teacher, decided to go to his house. The door opened Levina mother. Her face was very sad. The guys greeted and timidly asked: “Why does Leva not go to school?” Mom sadly replied: “He will no longer study with you. He underwent surgery. Unsuccessful. Leva went blind and cannot walk by himself ... ”

The guys were silent, looked at each other, and then one of them suggested:
- And we will drive him to the school.
- And to go home.
- And we will help to do the lessons, - interrupting each other, classmates chirped.
Mom's eyes filled with tears. She led the friends into the room. After a while, feeling the way with his hand, Lev came out to them with a blindfold. The guys froze.Only now they truly understood the misfortune that had happened to their friend.
Loew hardly said:
And then from all sides fell down:
“I’ll pick you up tomorrow and take you to school.”
- And I'll tell you what we went through in algebra.
- I'm on the story.

Loew did not know whom to listen to, and only confusedly nodded his head. Tears rolled down the mom's face. After leaving, the guys made a plan - who when comes in, who explains what subjects, who will walk with Lev and drive him to school. At school, the boy who sat with Levoy at the same desk, quietly told him during the lesson what the teacher wrote on the blackboard. And how the class died when Lyova responded! How everyone enjoyed his fives, even more than his own! Studied Lev fine. It became better to learn and the whole class.
In order to explain a lesson to a friend who is in trouble, you need to know it yourself. And the guys tried. Moreover, in winter they began to drive Levu to the rink. The boy loved classical music, and classmates went with him to symphony concerts ...

School Leva graduated with a gold medal, then went to college. And there were friends who became his eyes. After the institute, Lev continued to study and, eventually, became a world-famous mathematician, academician Pontryagin. Do not count people who have come to sight for good.

Lev Semenovich Pontryagin (1908-1988) - Soviet mathematician, one of the greatest mathematicians of the 20th century, academician of the USSR Academy of Sciences, who lost his sight in 14 years. He made a significant contribution to algebraic and differential topology, the theory of oscillations, calculus of variations, control theory. In control theory, Pontryagin is the creator of the mathematical theory of optimal processes, which is based on the so-called Pontryagin maximum principle; has fundamental results for differential games. The works of the Pontryagin school had a great influence on the development of control theory and calculus of variations all over the world.
