Ch. 101Breaking the Ten-Billion Barrier
Summary
1. Key Plot Points and Events
- In a Peking University dorm, roommates Wang Hao, Liu Qiang, and Chen Nan discuss a mathematics lecture, then wonder why Li Dong hasn't returned.
- Li Dong arrives, frustrated, revealing he was kicked out of the computer lab at closing time.
- He explains that he attended Academician Gao Wen's lecture on low-level algorithms and high-performance computing, then wrote a C++ program in the lab to verify nontrivial zeros of the Riemann Zeta function.
- Using cache-optimized memory blocking and Riemann's dimensionality-reduction algorithm, his program computed all nontrivial zeros up to beyond ten billion in just three hours on an ordinary lab computer—a remarkable feat.
- He was forced to stop before implementing multithreaded optimization, so he decides to buy a high-performance personal computer (he has over 300,000 yuan saved).
- The next morning, in a freshman general education class, an elderly professor stresses the difference between high school and university, encouraging students to enter research early and noting cash rewards for publishing in top journals.
- Li Dong mentally tallies potential papers: a physics paper on spontaneous symmetry breaking, a biology paper involving gene-knockout experiments on Alpine Hawkweed, and his Riemann zeta algorithm results—all potential money-makers. He wistfully notes he still lacks a computer.
2. Character Developments
- Li Dong: Demonstrates exceptional, cross-disciplinary talent; he effortlessly blends advanced mathematics with computer architecture, and already understands quantum field theory well enough to skip lectures. He shows ambition, pragmatism (viewing publications as financial rewards), and single-minded focus when optimizing algorithms.
- Roommates (Wang Hao, Liu Qiang, Chen Nan): Presented as typical sharp but somewhat conventional top students; they are confused by Li Dong’s choices, highlighting the gap between his abilities and their expectations. No major individual development, but they provide social contrast.
3. Significant Themes
- Knowledge creation vs. absorption: The transition from high school learning to university-level research and original contribution.
- High-performance computing and algorithmic genius: The power of combining mathematical insight with hardware-aware coding.
- Incentives in academia: Financial rewards for top-tier publications act as motivation.
- Prodigy isolation: Li Dong’s peers cannot fully grasp his interests or abilities.
4. Character Interactions
- Roommates tease Li Dong about a possible date, then react with disbelief when he reveals his actual activity (writing a computational proof).
- Li Dong briefly explains his choices: he skipped the physics lecture because computers are more important, and he had already studied quantum field theory.
- The professor’s lecture directly inspires Li Dong’s internal list of potential profitable publications, connecting academic guidance to his personal motivations.
