A comment on Brownian Motion.
Pollen grains are 10's of um, H2Os are 0.3 nm - 10^5 smaller. 10's of ng, vs 3e-14 ng - (10^5)^3 lighter. H2Os moving 600 m/s.
Imagine your body jerking around under a bombardment of relativistic bacteria.
The nanoscale mosh pit from hell.
Years back, a leading MEMS engineer giving a survey talk paused, and said with a deep deep well of feeling, "Brownian motion is the devil. The DEVIL."
