Dimension Code

In 2050, Lin Yuan is an ordinary researcher at the National Academy of Sciences. He has no presence. Sitting in a corner during a meeting, the projects were at the end of the queue. The old drawings that were rejected by his mentor twenty years ago were piled on his desk, gathering dust three feet thick. Then he saw the line of pencil writing. That was the instructor's handwriting, written in the margin of the paper on optical metamaterials - "The coating temperature deviated by 2 degrees and failed. It may be possible to use arc melting instead." He borrowed three hours to waste. At 142 minutes, the sample showed a silver mirror surface that had never been seen before. The cost of optical stealth is reduced to 3% of the original value. ——The system was discovered later. Lin Yuan named it "History Class Representative": it cannot predict the future, it can only allow him to see the footprints that were once only one step away from being correct, but were buried by time. Starting from an abandoned sketch, he "customized" the technology tree for the country step by step. Optical stealth. High density battery. Earth machine tools restore deep-sea platforms. The first wall material of controllable nuclear fusion. Space elevator base. The mecha hovers. Carbon-based chips. Dyson Cloud. Curvature-driven mathematical proof. And the further he walked, the more he discovered—— The handwriting of each piece of "historical annotation" is getting younger. From the vigorous regular script, to the scrawled charcoal pen, and finally, it completely overlaps with the wear and tear marks of my father's eternal flower pen. He is not predicting the future. He was reading the letters his father had never finished writing in his life. --- [This is not one person's road to becoming a god, it is the echo written by a generation on the edge of the paper] Someone asked him: Why do your generation beat time? Lin Yuan thought for a long time and answered: "Because someone has lost for us."
