They failed many times and faced doubt and laughter from others. But they never gave up their exploration. Finally, their creative idea came true. They invented the world’s first airplane and changed human transportation forever.
The story of the Wright brothers proves that ideas have great power. No idea is impossible. As long as we dare to imagine, think and persist, we can create miracles.

Creative thinking is not a talent that only a few people own. It is a habit that we can train in daily study and life. Many teenagers fail to be creative because they always wait for standard answers and hate thinking independently.
Miss Wang is a creative science teacher. In her class, she never tells students answers directly. Instead, she creates special situations and guides students to find problems, raise questions and solve problems on their own.
She encourages students to challenge traditional answers and come up with different solutions. She believes that even wrong answers are valuable because they show students’ independent thinking.
Slowly, her students no longer rely on textbooks. They become more active, curious and creative. They gradually understand that the true meaning of study is not to memorize knowledge, but to use knowledge and create new ideas.

Great ideas change the world. Throughout history, creative thinkers have brought huge changes to our society. Their fresh thoughts and brave attempts push human society forward.

During his lifetime, Einstein put forward many world-famous theories. His ideas completely changed people’s understanding of time, space and gravity. Although many people doubted him at first, his ideas were finally proved correct.
