Barenyi became disabled due to illness when she was a child, and her mother's heart was like a knife, but she still fought back her grief. She thinks that what children need most now is encouragement and help, not mother's tears. Mother came to Barenyi's sickbed and took his hand and said, "Son, my mother believes that you are an ambitious person. I hope you can use your own legs to walk bravely on the road of life! Good Barenyi, can you promise your mother? " Mother's words hit Barenyi's heart like a hammer. He threw himself into his mother's arms and burst into tears. From then on, whenever my mother was free, she would practice walking and doing gymnastics for Barenyi, and she was often so tired that she was sweating. Once my mother caught a bad cold, she thought that a mother should not only teach by words, but also by example. Despite her high fever, she got out of bed and helped Barenyi practice walking as planned. Soybean-like sweat trickled down from her mother's face. She wiped it with a dry towel and clenched her teeth, which helped Barenyi finish the exercise plan that day. Physical exercise makes up for the inconvenience caused to Barenyi by disability. Mother's role model has deeply educated Barenyi, and he finally withstood the severe blow of fate. He studies hard and his academic performance has always been among the best in his class. Finally, he was admitted to the Medical College of Vienna University with excellent results. After graduating from college, Barenyi devoted all his energy to the study of otology. Finally, I finally got on the podium of the Nobel Prize in Physiology and Medicine.

Hua Luogeng. After graduating from junior high school, Hua Luogeng went to Shanghai China Vocational School, but dropped out of school due to tuition fees, so he only had a junior high school diploma all his life.

After that, he began to teach himself tenaciously. He completed all the math courses in senior high school and junior college in five years. In 1928, he was unfortunately infected with typhoid fever, and his life was saved by his wife's care, but his left leg was disabled. At the age of 2, he caused a sensation in the field of mathematics with a paper and was invited to work by Tsinghua University.

Since 1931, Hua Luogeng has been working and studying in Tsinghua University, and he has completed all the courses in the Department of Mathematics in one and a half years. He taught himself English, French and German, and published many papers in foreign magazines. In the summer of 1936, Hua Luogeng was sent to Cambridge University in England for further study, and published more than ten papers in two years, which attracted the appreciation of the international mathematics community. In 1938, Hua Luogeng visited Britain and returned to China. In a small attic like a cowshed on the outskirts of Kunming, he struggled to write the famous book "The Theory of Prime Numbers in Stacking Bases".

In the middle of December p>1914, Edison's manufacturing equipment was seriously damaged by a fire, and he lost about 1 million dollars and most of his work records which were difficult to calculate with money. The next morning, he walked beside the ashes where he had buried the fruits of his years' labor. The inventor said, "A disaster has the value of disaster. All our mistakes have been burned, and now we can start over." Edison's achievements are really admirable, but what is even more admirable is his courage to face setbacks. The journey of life will inevitably be difficult, bumpy or a heavy blow. In the face of these, you can be sad, you can regret, but the important thing is not to lose the courage to face it, but to have the courage to overcome yourself.
