不可能三角
量子力学测不准原理：无法同时测得粒子的位置和动量，一个值测得越准，会导致另一个值误差越大越不准。
经济学有三元悖论：资本自由，固定汇率，独立货币政策。
智慧体同样面临不可能三角：计算的准确性，计算的速度，计算的持久性。
追求计算的准确性，就会牺牲速度和持久性；追求运算速度，就会牺牲精度和持续性；追求持久性就要牺牲准确性和速度。
The ADHD Algorithm: From Dijkstra to SSSP
In 2025, computer science witnessed one of its most dramatic plot twists. Professor Ran Duan's team at Tsinghua published "Breaking the Sorting Barrier," demolishing a 50-year-old assumption about shortest path algorithms. The timing was almost comedically perfect—just one year after FOCS had awarded its best paper prize to research proving the "Universal Optimality of Dijkstra." From mathematical perfection to mathematical revolution in twelve months flat. For most people, this academic drama might seem abstract. But for those of us navigating life with ADHD, these two papers accidentally outlined the most effective time management system we never knew we needed. Main takeaways: Dijkstra Algorithm - Dimensionality Reduction : Remove the time dimension from project planning, which ADHDers struggle with most. SSSP Algorithm - Pruning : Prevent decision paralysis and overthinking by eliminating irrelevant choices. Universal Optimality - First Principles : Mathemat...
