This is fascinating. I mean we all know the theory, but to actually see the cells under magnification puts you in range, and makes you wonder what else there is to know. And the answer is always MORE.
Education should work more practical application in with the theory. I'm looking at you, calculus!
I mean, calculus is a thorny issue in that it is mostly necessary for engineering, but is not usef for humanities. Not teach it, and STEM people will have jump of levels going college. Teach it, and humanities people will inevitably complain.
Personally, I think it is good to teach calculus just for the technical communication aspect.
Seriously. I'm in my 40s and this is the first time I've ever had any sense of scale for red blood cells. Very cool!
But it's hard to perceive the scale of the needle tip itself, so there's no good reference object for the scale. They should have included banana or something for the comparison.
