Third, we should have tenacious perseverance in learning mathematics. For example, after Hua's left leg was disabled due to illness, he had to draw a big circle on his left leg and take a small step on his right leg. For this strange and laborious step, he once humorously called it "the movement of circle and tangent" In adversity, he stubbornly resisted his fate and vowed: "I will replace my imperfect legs with a sound mind!" " With this spirit, he finally grew from a young man with a junior high school diploma to a generation of mathematicians. Hua is an effective researcher and founder of analytic number theory, gauge group, matrix geometry and self-directed function theory in China. , his book "heap prime number theory" became a classic of mathematics works in the 20th century. It is with this indomitable spirit that China can reach the peak of science in adversity.
Fourth, be good at observing life and be diligent in thinking. Newton and Archimedes were like this. Once he was reading under a tree, suddenly an apple fell from the sky and landed on his head. Newton painstakingly thought about why the apple fell, so he began to calculate, and then discovered the gravity that caused a sensation in the world.
What about Archimedes? King Luo Hai of Syracuse once again asked the goldsmith to build a pure gold crown. Because it is suspected that there is silver mixed in it, Archimedes is invited to identify it. When he entered the bathtub to take a bath, the water overflowed the tub, so he realized that although the weight of objects made of different materials was the same, the water discharged would be unequal because of the different volumes. According to this truth, it can be judged whether the crown is adulterated. Archimedes jumped up happily and ran home naked. Shouting "Found found", he summed up the basic principle of hydrostatics in his famous "On Floating Bodies", that is, the weight of an object reduced in a liquid is equal to the weight of the discharged liquid, which later became the famous Archimedes principle.
