time-cost trade-off

While human achievements in mathematics continue to reach new levels of complexity, many of us who aren't mathematicians at heart ( or engineers by trade) may struggle to remember the last time we used calculus.

虽然人类数学成就的复杂性持续再创新高，但我们当中许多本身并非数学家(或者职业并非工程师）的人，可能很难记住我们最后一次使用微积分是什么时候了。
