The content of the concise scientific handwritten newspaper: The story of Joule

The famous British scientist Joule loved physics since he was a child. He often did some things about electricity and heat by himself. Such experiments.

One year during the holidays, Joule and his brother traveled to the countryside together. The smart and studious Joule did not forget to do his physics experiments even when he was playing. He found a lame horse, held by his brother, and quietly hid behind it. He used a Voda battery to pass current to the horse, hoping to test the animal's reaction after being stimulated by the current. As a result, the reaction he wanted to see occurred. The horse jumped wildly after receiving the electric shock, and almost kicked his brother.

Although danger has appeared, this has not affected the mood of Xiao Joule, who loves to experiment, at all. He and his brother rowed a boat to a lake surrounded by mountains. Joule wanted to test how big the echo was here. They filled their muskets with gunpowder and pulled the triggers. Unexpectedly, with a bang, a long flame spurted out from the muzzle of the gun, burning off Joule's eyebrows and almost scaring his brother into falling into the lake.

At this time, the sky was covered with thick clouds and there was lightning and thunder. Joule, who was just about to go ashore to hide from the rain, found that the rumble of thunder could only be heard after a long time after the lightning. What was going on? Joule couldn't care less. Hiding from the rain, I dragged my brother up a hill and carefully recorded the time between lightning and thunder with my pocket watch. After school started, Joule couldn't wait to tell the teacher all the experiments he had done and asked for advice. The teacher looked at the studious and inquiring Joule and smiled, and patiently explained to him: The propagation speeds of light and sound are different. The speed of light is fast and the speed of sound is slow, so people always want to see lightning and then hear thunder, but in fact The lightning and thunder happened at the same time. ?

Joule suddenly understood after hearing this. From then on, he became more obsessed with learning scientific knowledge. Through continuous learning and careful observation and calculation, he finally discovered the thermal work equivalent and the law of conservation of energy, and became an outstanding scientist.

With the support of a noble purpose, if you work non-stop, even if it is slow, you will definitely succeed.

I think that in all situations, only love is the best teacher. ?Einstein’s Quotations

Studying is like planting trees, which bloom in spring and bear fruit in autumn.

How many unsolvable mysteries are there in the world and the universe? Let’s hurry up and work!

I never think about the future, it comes too fast

Nothing of real value comes from ambition or a simple sense of duty, only love and devotion to humanity and to objective things.

The ideals that inspire me and always fill me with joy in life are truth, goodness and beauty. ?Einstein’s famous sayings

No matter what the trend of the times and social fashions are, people can always rely on their noble qualities to transcend the times and society and follow their own correct path. Nowadays, everyone is running, chasing, and competing for refrigerators, cars, and houses. This is characteristic of our time. But there are also many people who do not pursue these material things.

It is best to keep one's hobbies and profession as far apart as possible. It is unwise to combine a man's livelihood with his God-given talents.

Raising a question is often more important than solving a problem, because solving a problem may just be a teaching or experimental skill. Raising new questions, new possibilities, and looking at old problems from a new perspective all require creative imagination and mark real progress in science.

A soul without imagination is like an observatory without a telescope? Einstein’s famous saying

Scientists must grasp certain universal characteristics that can be expressed by precise formulas in the vast and complex empirical facts. , thus exploring the universal principles of nature.
