Sparks Shine Brightly in the East

This article will focus on the integration of revolutionary spirit and scientific service to the country, creating an epic of family and country spanning forty years. 1. Silver bracelet galaxy The miniature carvings inside the bracelet project a star map under the moonlight, which is not only the retreat route of the Red Army, but also coincides with the ballistic calculation model. When Cheng Xinghe conquered the guidance algorithm, he always used a bracelet to hold drawing ink. 2. Blood and Fire Equation The manuscript Lin Qiubai left in "Chu Ci" was written in partial differential equations with gunpowder smoke and blood. Twenty years later, these formulas became the key to solving rocket propellant oscillations. 3. Pocket watch password Cheng Moyang's field pocket watch can automatically calibrate according to latitude, and the watch chain has a hidden Morse code. Professor Qian Sen found the crux of the problem of out-of-control missiles by deciphering the notches on the watch cover. 4. Red silk data The red computing chip in Shen Molan's laboratory is based on the wedding dress Lin Qiubai wore when she died. She used these calculations to design a unique telemetry coding system for "Dongfanghong No. 1". Key scene Winter 1962 Jiuquan Base Cheng Xinghe ran wildly in the snowstorm, and the hands of his pocket watch stagnated at three seventeen due to the low temperature. He suddenly remembered the record in his mother's notes that "the star points to the north, and the enemy is in the sky" and adjusted the launch angle by 0.17 Degrees. Early the next morning, my country's first weather rocket pierced the clouds. 1970 Qingming Wind Tunnel Laboratory Shen Molan handed the blood-stained formula book to Cheng Xinghe: "When your mother was using an abacus to deduce the rocket equation, a bullet from a Kuomintang agent penetrated her inkstone...
