There is a famous saying: "Learn mathematics, physics and chemistry well, and you will not be afraid of traveling all over the world." But as a mathematics teacher, I know very well that mathematics and science are the most troublesome subjects for students, especially students in rural middle schools! When I was listening to reading at ten o'clock, I accidentally heard Liang Heng's "Popular Romance of Mathematics, Physics and Chemistry", which was mainly written for students' boring study of mathematics, physics and chemistry, so I did not hesitate to buy this set of books, which has five volumes. , I have read two volumes so far. This book is a very good book that makes people more interested in mathematics, physics and chemistry.

Archimedes discovered the theory of buoyancy while taking a bath; Newton was hit by an apple and then discovered the gravity of the earth... Interesting stories about scientists attract us to understand the history of science. And then learned about science.

The book mainly uses stories to tell the origin of important theorems or formulas in mathematical physics. For example, the discovery of irrational numbers; the lever principle; concave mirrors; Kepler's theorem; rectangular coordinates; universal gravitation, etc. And with corresponding illustrations, it makes people more curious and makes reading more interesting! However, after reading the first two volumes and closing the book, my heart was so shocked that I couldn't calm down for a long time. It turns out that the path of scientific exploration is extremely tortuous, and scientists have to make sacrifices before every scientific history begins. They do not hesitate to lose their lives in order to explore science. Therefore, behind the occurrence of science lies the spirit of scientists.

Regarding the irrational numbers that everyone is familiar with, the great scientist Hippasus discovered that when the two right-angled sides of an isosceles right triangle were rational numbers, its hypotenuse was not a rational number, and was actually considered by the Pythagoreans to be Rebellion and being thrown into the sea alive;

There are also the lever principle and the light-concentrating effect of concave mirrors that everyone is familiar with. Their inventor is Archimedes. He used the principle of leverage to invent a stone-carrying device and defeated the Roman army; he used the light-gathering effect of concave mirrors to let the old, weak, women and children use a mirror to repel thousands of armies. It can be said that in the eyes of everyone, he is such a myth. But unfortunately, he died by the sword of an ignorant Roman soldier in the end. However, even if he dies, he still wants to protect his invention. In order to leave scientific knowledge to future generations, he would rather die and hope that ignorant people will not trample on his graphics and his sand table!

Galileo, the first scientist to use telescopes to observe celestial bodies and achieve a lot of results, was imprisoned for supporting the heliocentric theory and was sentenced to 300 years in prison. This ultimately led to the longest unjust case in the history of science!

Bruno was burned alive for defending Copernicus’ heliocentric theory; Faraday discovered the phenomenon of electromagnetic induction, but it took 23 years before it was recognized and valued by the public... No matter how difficult it is, they all respect and love science. , as long as it is the truth, I would rather die than surrender. While we read stories and learn knowledge, we should also learn the spirit of scientists who relentlessly pursue the truth and have the courage to defend the dignity of science. Their scientific spirit of exploration, questioning, verification, and innovation is worth learning from.

? Oh my god, it’s really unimaginable. No matter how smart a person is, he still needs someone who understands him, otherwise even science will be called ridiculous! But after finishing the first volume, I will be looking forward to the second volume, because each storyline is memorable. Suddenly, we, as descendants, only know how to use the fruits of labor of our predecessors, but never know every scientific There are so many amazing truths behind the truth! The source of each theorem makes people reflect! I hope there will be more surprises in the next four volumes...
