The mathematician James England has even developed a mathematical theory which states that life has to happen, that it's as miraculous as a rock rolling down a hill.

数学家詹姆斯·英格兰甚至创立了一个数学理论，用来说明生命是必然产生的，生命的产生就像岩石滚下山坡那样不可思议。

Instead of despairing, Camus imagined Sisyphus defiantly meeting his fate as he walks down the hill to begin rolling the rock again.

加缪没有绝望，而是想象西西弗斯在下山重新开始滚石时勇敢地面对自己的命运。

So that might involve steeper slopes, but it can sometimes even involve rolling rocks or logs onto a trail to keep up its difficulty quotient.

因此，这可能涉及更陡的斜坡，但有时甚至可能需要将岩石或圆木滚到小路上，以保持其难度系数。
