But he probably is known best for another invention -- the geodesic dome. A geodesic dome is a round building made of many straight-sided pieces.

但他最著名发明可能是另一项发明——测。测是由许多直边构件组成形建筑。

Light rays too must follow geodesics in space-time.

光也必须遵循时空中测。

But his tendency to make great leaps from slight data meant his ideas often lacked solid foundations—much like his geodesic domes, novel structures that soared skywards without apparent support and occasionally came crashing down.

但他倾向于从微不足道数据中取得巨大飞跃， 这意味着他想法往往缺乏坚础——就像他测穹一样， 新颖结构在没有明显支撑情况下直冲云霄， 偶尔会轰然倒塌。

In Euclidean geometry, the geometry of Newtonian physics, that is a straight line, but in the geometry of space-time, a geodesic can be curved.

在欧几里得几何， 即牛顿物理学几何体系中，这是直； 但在时空几何中，测可以是弯曲。
