Whereas large animals swim by pushing against water with their fins or limbs, this approach is ineffective at very small scales.

而大型动物通过用它们的鳍或肢体滑水的方式游泳，这种方式在微观比例下是低效率的。

But until now, the movements have always been restricted to very small scales, typically across distances of a few hundred micrometers, and mostly in liquids.

但时至今日，移动的距离一直限制在很小的范围内，通常能移动几百微米的距离，且大部分都是在液体中移动。

According to string theory, space has six extra dimensions that we don't see because they're curled and tangled up at very small length scales.

根据弦理论，空间有6个额外维度，我们看不见，因为它们蜷缩纠缠在很小的范围里。

This is especially true at very large and very small scales (think astronomy or particle physics), but also liminal spaces or large sociotechnical systems that cannot be experienced completely or directly (think cyberspace, but also large infrastructure systems like power grids, interstrate highway systems, etc.).

"The physics of flight at such small scales is relatively poorly understood which makes designing small flying systems very difficult, " he told BBC News, adding that biological systems provided "critical insights into designing our own artificial flyers".

However, when the very mechanism installed to serve becomes the served, when the scales of fairness and power tilt to a small group of centralized leaders, a divided populous is inevitable as the quest for power dictates behavior.
