Looking at recent Friday videos, we’ve been spending a good amount of time in the microscopic world. Can you blame us, given the state of the macroscopic?

Regardless, given all of this microscope gazing, one has to ask the question, why don’t we have gigantic bacteria? The answer comes down to a question of diffusion and the relationship of surface area to volume, as shown in the video below.

So the good news is that giant bacteria is one less thing we have to worry about in 2020.
