A technical discussion, pushing around ideas about energy and star systems, Einstein hopping, the trees blazing through the window.

展开技术探讨，不断碰撞关于能源与星系的想法，爱因斯坦雀跃不已，窗外树叶火红映进屋内。

I learned to find the Andromeda galaxy by "star-hopping" from the star Alpheratz in Great Square to the two stars marked here – first Mirach, then Mu Andromedae.

我曾经学过用“星星跳跃式”从大广场的壁宿星跳到这里标记的两颗星——奎宿九星和穆仙女座。
