... 硬碟(HDD)延迟以毫秒(milliseconds)计算,NAND延迟以微秒(microseconds)计算,而3D XPoint技术的延迟则是以奈秒(nanoseconds,十亿分之一秒)计算。举例来说, HDD在篮球场长度冲刺所需的时间,NAND能跑完一趟马拉松,而3D XPoint技术几乎可绕地球一圈。

So, let's think qualitatively for a second about what that means or what the real meaning of that is. What that is telling us is that according to Newtonian mechanics and Coulomb's force law, is that the electron should actually plummet into the nucleus in 0.1 nanoseconds.
让我们定性的想想,这意味着什么,这告诉我们,根据牛顿力学,和库仑定律,电子,在0。1纳秒内,就会掉到原子核里面。
If I'm running at nanosecond speed, 1000 n, the size of the problem, whatever it is, is 1000, and I've got a log algorithm, it takes 10 nanoseconds to complete.
