Wikipedia states "Vitamin D toxicity, or hypervitaminosis D is the toxic state of an excess of vitamin D. The normal range for blood concentration is 20 to 50 nanograms per milliliter (ng/mL). However, the toxic state is known to be a value of 100 ng/ml or more in a clinical setting."
This is wrong because toxicity is not a pure function of vitamin D concentration. I'm above 100 ng/ml and yet my calcium is normal. The toxicity is purely a result of elevated calcium levels. The threshold level of D which causes this elevated level of calcium seems to vary significantly between individuals, and in any case, is much higher than the numbers that google or wikipedia gives you. At any rate the 4000 IU number is unscientific nonsense.
Also the point of reading Euclid is not really to learn geometry but rather to investigate and examine the oldest, most primordial expression of the idea that math should be formalized using a few axioms.
I don't think AoC is enough here becuase the wizards need to evaluate the choice function to get the representative from each equivalence class. AoC merely states that there is some function that maps each equivalence class to some element within that equivalence class. It doesn't tell you how to actually evaluate it, which is what the wizards need to do.
