The state of physics for most human bodies is "avoid things that are too hot/cold, electricity and heavy things requiere more energy to move, things fall when thrown up"

With those kind of basic ideas you can mostly survive and figure your way around. No one needs to check spin on electrons when living their day to day. Or the mass of a neutron star versus a blackhole

Similarly, nutrition science can be extremely specific about gut microbiome compositions and its effect in regulating specific hormones and so on. But most humans just need the guidelines of dont over eat, have mostly fish/legumes and veggies and be active (strength training and regular walks) to have a healthy life.

no one needs to know the exact frequency and voltage of your plug to be taught to not stick your giners on the wall, and no one needs to know the exact victamin C and iron content of spinach to know its healthier than ultraprocessed chips
