The Persistent Inventor A young student of meteorology was having a difficult time with an experiment. He was attempting to duplicate lightning in clouds. He had made a device that could simulate lightning. It worked by releasing an electromagnetic pulse into the cloud. This pulse, in turn, stimulated the electrons in the cloud's particles. Then, the electrons produced lightning. But his meteorological experiment had a major defect. He couldn't get the device into the sky. He had tied it to balloons, but they had burst. He had shot the device from a cannon, but the force of the cannon had damaged it. "You should give up, his friends told him. You'll never get that thing into the air." But his friends' criticisms only spurred him to try again. The student was very innovative, and at last, he thought that he had an innovation that would work. He attached wings to the device, and on one dreary day, when clouds blocked the light of the sun, he started his experiment anew. He placed the device on a rocket and launched it into the sky. The propulsion of the rocket carried the device high into the air. The rocket accelerated into the clouds and then released the device. It glided on its wings through the clouds, and when it penetrated the center of a large black cloud, it emitted the electromagnetic pulse. And just as he had predicted, lightning shot from the cloud! He called his professors, and the next day, they came to watch. He successfully duplicated the experiment. His teachers were extremely impressed and called the student and his invention ingenious. The student was given many awards and became a famous inventor. He had not given up. He had remained persistent and succeeded.

一个年轻的气象学学生在做一个实验时遇到了困难。 他试图在云中复制闪电。 他制造了一个可以模拟闪电的装置。 它的工作原理是向云层释放电磁脉冲。 这个脉冲反过来又刺激了云粒子中的电子。 然后，电子产生了闪电。 但他的气象实验有一个重大缺陷。 他没能把装置送上天空。 他把它绑在气球上，但气球破裂了。 他用大炮射击了这个装置，但是大炮的威力把它损坏了。 “你应该放弃，”他的朋友们告诉他。 你永远不可能把那东西飞到空中。” 但朋友们的批评只会激励他再试一次。 这个学生很有创新精神，最后，他认为他有了一个可以奏效的创新。 他给仪器装上了翅膀，在一个阴沉沉的日子里，云层遮住了阳光，他重新开始了他的实验。 他把这个装置装在火箭上，发射到天空中。 火箭的推进力把这个装置带到了高空。 火箭加速进入云层，然后释放了装置。 它用翅膀在云层中滑翔，当它穿过一片大黑云的中心时，它发出了电磁脉冲。 正如他所预测的那样，闪电从云层中射出！他打电话给他的教授，第二天，他们来观看。 他成功地重复了这个实验。 他的老师们印象非常深刻，称这个学生和他的发明很有独创性。 这个学生获得了许多奖项，成为了一名著名的发明家。 他没有放弃。他坚持不懈，取得了成功。
