In the long history of mankind, we have been trying to explore and master the method of measuring time. Hourglass, water clock, etc. Are devices invented by the ancients to measure time. Today, these devices can only be regarded as timing tools at most, but at that time, it was a huge progress, and this method has been used until the17th century. It was not until 1656 that the first pendulum clock in human history was born, and Huygens invented it. However, no matter once or now, or in the future, when it comes to pendulum clocks, there is one person who can never jump, and that is the great physicist Galileo, the discoverer of the synchronicity of simple pendulum. In fact, it is not only creation and discovery, but also Galileo's pendulum story has brought us different enlightenment.

1. Galileo discovered that the pendulum is isochronous. Galileo, who was only 18 years old at that time, once went to church in Pisa, and a chandelier hanging on the ceiling caught his attention. The breeze blew and the chandelier kept swinging back and forth. The keen Galileo later discovered that with the passage of time, the amplitude of the chandelier swing gradually decreased, but the time required for a swing did not seem to change. So Galileo held his pulse and made a rough calculation, and the result confirmed his intuition. He couldn't wait to finish his service, so he hurried home and did a series of experiments to study the law of swing. Finally, he found that as long as the length of the rope used to hang things remains the same, no matter how heavy the thing is, how big the swing is, and how the swing period changes, the time required to complete a swing is the same. This is the beginning and foundation of accurate timing of human beings: isochronism of simple pendulum? Principle. Who would have thought that the discovery of such a great principle was only because of a curiosity?

Second, Galileo's pendulum story inspires us. Galileo's discovery of the pendulum stems from his momentary curiosity. In fact, we can see that many great inventions originated from a moment of curiosity. Therefore, our education should also create an environment that can nourish children's curiosity, so that children can learn because of curiosity. This is driven by curiosity to stimulate children's desire to learn, not because they want to learn and want to get good grades. When we create an environment for children to stimulate their curiosity, we will find that children can do much more than you think.

Einstein once said: I'm nothing special myself, just full of curiosity. ?

Isn't this the essence of innovation? Curiosity is the guide on the road to creating science. In education, children who don't follow the rules and cross the line must be good children. On the contrary, there are always some fantastic ideas. Even children who occasionally make mistakes are not necessarily not excellent. Parents and schools should fully encourage children's curiosity, which is conducive to the cultivation of innovative talents.
