Friends and family have often stated that I have a good memory. For me, having only one data point, my memory is ‘average’, though many will dispute that. I have referred to my memory as a virtual landfill of information, though in retrospect that doesn’t fit either. The term “landfill” implies that it is filled with garbage, or items that are no longer useful. Instead, I’ve come to compare the ideas bouncing in my head to a large tub full of Lego bricks. Each brick has the potential to construct a much larger cohesive structure. The same is true about the ideas in my head.
Today, we’ll return to high school biology. “Wait, what?!” That’s right, high school biology (and maybe a bit of algebra and chemistry sprinkled in). The lesson of diffusion in biology is that particles move from a higher concentration to a lower concentration. Furthermore, they also taught the lesson of osmosis, which is diffusion through a semipermeable membrane. I’ll admit that I remember a rather unhealthy quantity of high school lessons.
