Ch. 61National Competition Opens!
1. Key Plot Points and Events
- The Mathematical Modeling Competition begins on September 12. Lu Zhou and his teammates return to the old campus, settle into dorms, and prepare for the 72-hour contest.
- At 8:00 AM, teams download the problems: Problem A (Chang’e 3 soft-landing trajectory design and control strategy) and Problem B (design of a creative folding table). Both are physics-heavy; most teams panic or struggle.
- Lu Zhou chooses Problem A, despite its aerospace physics difficulty, because he has already self-studied the relevant physics and because many others will flock to Problem B—giving his team a comparative advantage.
- The team divides roles: Lu Zhou handles both modeling and paper writing, Wang Xiaodong does programming, Lin Yuxiang handles errands (food and water).
- Lu Zhou immediately begins drafting the paper, establishing the problem analysis and overall modeling framework for the three sub-questions, while mentally organizing the entire solution structure.
2. Character Developments
- Lu Zhou: Shows strategic thinking, confidence, and leadership. He has prepared extensively (self-studied University Physics and even Aerospace Physics) and can work efficiently under pressure. He enters a deep focused state, turning the outline into mathematical language.
- Wang Xiaodong: Trusts Lu Zhou’s decisions completely, accepts his role as programmer without objection, and demonstrates quiet competence.
- Lin Yuxiang: Eager to contribute, though her role is limited to logistical support. She accepts her assignment cheerfully.
- Other contestants: Revealed as flustered and unprepared, highlighting the difficulty of the problems and the competitive environment.
3. Significant Themes
- Strategic competition: Choosing problems based on anticipated distribution of contestants, not just difficulty.
- Division of labor and teamwork: Efficient role allocation (lead, programmer, support) is key to success.
- Preparation meets opportunity: Lu Zhou’s prior self-study gives him an edge in a seemingly insurmountable challenge.
- The central importance of the written paper: Lu Zhou treats the paper as the core deliverable, integrating modeling and writing simultaneously to save time.
4. Character Interactions
- Lu Zhou & Wang Xiaodong: Communicate almost nonverbally; a glance suffices for agreement on problem choice and role assignment.
- Lu Zhou & Lin Yuxiang: Lu Zhou unceremoniously assigns her to fetch supplies; she responds with enthusiastic agreement.
- Teacher Liu: Makes a brief, non-pressuring visit, asking about well-being but avoiding competition talk.
- Background interactions: Other teams discuss and panic; some (like Luo Rundong, Liu Rui) appear composed and begin organizing their own work, contrasting with the chaos.
