用月亮来观察地球重新建立了外星行星凌日的基本几何学原理，同时平衡了穿过整个大气层的影响。
Using the Moon to view Earth recreates the basic geometry of exoplanet searches, as well as averaging the effect across the entire atmosphere.
第三章的“自然的几何学”表明了我们所寻求的设计原则，即明确地连接了从分子到行星不同规模水平。
"Nature's Geometry," the third chapter, suggests that we look for design principles that explicitly link different levels of scale from the molecular to the planetary.
但是，这个深入研究的行星状星云的范例，映射着类星体临近死亡的状态；被认为是个令人惊讶极其复杂的几何学。
But this well-studied example of a planetary nebula, produced near the end of the life of a sun-like star, is now understood to have a surprisingly complex geometry.
