i'm trying

Well, with work and being sick, I haven't gotten very far in my life sciences study. But I am noticing that, wow, i sure as hell didn't retain much. The first chapter is covering the basics of measurement used (metrics). I might have to read this chapter a couple times just to remember these ...or make some cheat sheets to hang above the computer. Did you know the herpes virus is 100 nanometers in diameter, four times the size of the polio virus?
