But if you think about the bigger picture, what's inside the Earth, all this surface level stuff becomes irrelevant.
但如果你考虑更大的图景，地球内部是什么，所有这些表面层面的东西都变得无关紧要。

地心游记-The journey to the heart of the Earth
The gloom upon them deepens; and they soon present to our view a ponderous mass of almost level surface.
他们的忧郁情绪加深了；他们很快就在我们的视野中呈现出一个几乎水平的巨大物体。

" It was like a tsunami. And instead of being generated by an earthquake, it was really the typhoon that pulled the surface sea level and brought it up by 4 to 6 meters."
“这次台风堪比海啸。海平面升高4到6米，完全是由台风引起的，而不是地震的缘故。”

Thus the moraine soil and the necessary moisture requisite for the better class of meadow plants are at times combined about as perfectly as if smoothly outspread on a level surface.
因此，冰碛土和更好的草甸植物所需的必要水分有时会完美地结合在一起，就好像平滑地铺展在水平表面上一样。

When we're led by our ego, our main priority is to maintain the status of the eye in the world, and we're just focused on how external events affect us, and everything is very superficial and surface level.
当我们被自我意识引导时，我们的首要任务是关注自己在世上的地位，我们只关注外部事件如何影响我们，一切都非常肤浅。

水平集 Level set
（重定向自Level surface）
在数学领域中, 一个具有n变量的实值函数f的水平集是具有以下形式的集合
- { (x1,...,xn) | f(x1,...,xn) = c }
其中 c 是常数. 即, 使得函数值具有给定常数的变量集合.
当具有两个变量时, 称为水平曲线(等高线), 如果有三个变量, 称为水平曲面, 更多变量时, 水平集被叫做水平超曲面.
集合
- { (x1,...,xn) | f(x1,...,xn) ≤ c }
被称为 f 的 子水平集 .

Level set 水平集
（重定向自Level surface）
In mathematics, a level set of a real-valued function f of n real variables is a set of the form
that is, a set where the function takes on a given constant value c.
When the number of variables is two, a level set is generically a curve, called a level curve, contour line, or isoline. So a level curve is the set of all real-valued solutions of an equation in two variables x1 and x2. When n = 3, a level set is called a level surface (see also isosurface), and for higher values of n the level set is a level hypersurface. So a level surface is the set of all real-valued roots of an equation in three variables x1, x2 and x3, and a level hypersurface is the set of all real-valued roots of an equation in n (n > 3) variables.
