1907年时,爱因斯坦似乎没能预见到这样的时代,在这个时代,“镭射光钳”发射双重激光,从而困住灰尘一般大小的玻璃微粒,使它们悬浮在空中。
In 1907, Einstein likely did not foresee a time when dust-sized particles of glass could be trapped and suspended in air by dual laser beam "optical tweezers."
美国康奈尔大学的一位气候学家娜塔莉·马霍瓦尔德表示,迄今为止,科学家们一直都在设法获悉悬浮微粒在空中有什么作用。
Natalie Mahowald, a climate researcher at Cornell University, says so far, scientists have mostly tried to understand what those aerosols do while they're actually in the air.
