The first particle she queries will most likely have traveled the shortest possible path through the maze.

她询问的第一个粒子走过的路径最有可能是穿过迷宫的所有可能路径中最短的一条。

When a charged particle zips through the chamber, the vapour condenses into a trail of droplets showing the particle's path and, if the box is placed in a magnetic field, its electrical charge.

当一个带电粒子快速穿越云室时，水汽会凝结形成一串小液滴，这样便标识出了该粒子的路径；若将容器置于一个磁场中，还能知道粒子所带电荷的性质。

However, even that calculation may not reflect how long the particle would take to cross the Pacific, since it would not likely cross the ocean in a direct path.

然而，甚至计算也可能不会反映放射性微粒穿越太平洋所花的时间，因为它不可能径直穿越太平洋。

There's another path by which they can learn about accelerators and particle detectors essentially, how do we know any of this.
