Independent独立完成

Problem问题: Beijing winters were heavy with smog. He walked to school in a mask, and classmates complained about the air. He asked why there was not a system that could say, a day ahead, which days would be all right and which days needed a mask.北京冬季雾霾严重。他上学戴着口罩，同学都在抱怨空气。他问：为什么不能有一个系统，提前告诉我们哪天空气好，哪天需要戴口罩？
What he did做法: Python read a public air-quality API. A simple method estimated the next day’s PM2.5. An email then went to family and friends.用 Python 读取公开空气质量 API，用简单算法估计次日 PM2.5，再自动发邮件给家人与朋友。
Result结果: The system was crude and not very accurate. Family and friends received the emails.系统简陋，准确率也不高。家人和朋友收到了这些邮件。

Programming lead编程组组长

Problem问题: A competition robot had to avoid obstacles, move an arm, and choose a path through a maze, with a team rather than alone.比赛机器人需要避障、驱动机械臂，并在迷宫里选择路径。这是团队的问题，不是一个人的练习题。
What he did做法: He designed the obstacle-avoidance algorithm, wrote the arm-control program, and tuned the path-planning logic.他设计自动避障算法，编写机械臂控制程序，并优化路径规划逻辑。
Result结果: The team placed second in the regional maze challenge.团队在区域赛迷宫挑战中获得第二名。

Independent独立完成

Problem问题: Three motions, each written as its own program: free fall, a planetary orbit, and a pendulum.三种运动，每种写成一个程序：自由落体、行星轨道、单摆。
What he did做法: He wrote his own Python simulators for each motion.他用 Python 为每一种运动自建了模拟器。
Result结果: Three Python simulators, one for each motion.三个 Python 模拟器，每种运动一个。

Independent独立完成

Problem问题: The night CM Level 10 was not passed, the question was specific: where does the timing of the playing actually slip?CM Level 10 没有通过的那天晚上，问题变得很具体：演奏的节奏，究竟是在哪里不稳？
What he did做法: He used audio signal processing and the Fast Fourier Transform to look at beat stability.他用音频信号处理和快速傅里叶变换（FFT）分析节拍稳定性。
Result结果: A program that measures beat stability in his own recordings. It was not a class assignment.一个测量他自己录音中节拍稳定性的程序。不是课堂作业。

Independent study独立研究

Problem问题: Classmates were anxious under academic pressure. A family research project raised the question of whether a program could notice that strain.同学因学业压力而焦虑。一个家庭研究项目提出的问题是：程序能否察觉这种压力。
What he did做法: He is teaching himself natural language processing, sentiment analysis, and ways of handling data that protect privacy. The aim is a non-intrusive emotional check-in for teenagers.他正在自学自然语言处理、情感分析算法，以及隐私保护的数据处理方法。目标是一个非侵入式的青少年情绪追踪工具。
Result结果: Early stage. No deployed product, and no measured outcome.仍在早期。没有已上线的产品，也没有测量过的效果。

Independent study独立研究

Problem问题: He has lived in Beijing during smog and in California during wildfire season. The work is a personal carbon tracker and a look at household electricity use.他在北京经历过雾霾，在加州经历过野火季节。这项工作是个人碳足迹追踪，以及家庭用电的记录。
What he did做法: A personal carbon tracker, and notes on household electricity use.个人碳排放追踪，以及关于家庭用电的记录。
Result结果: Still an exploration. No measured impact is recorded.仍在探索。没有记录过可测量的影响。
