In a perfect world, elementary grade school kids could be set an series of simple arithmetic problems, based on the information contained within any number of peer-reviewed articles, published in highly reputable scientific journals, on the early wartime production of penicillin by penicillium fungus.
After all the basic arithmetic is dead simple, but unfortunately the scientists were allowed to fudge the vital numbers , time and again, all to better flatter the humans nominally in charge of the penicilliums' production, the patients be damned.
