This is an interesting concept from my uncle. Not sure if it works or not.
As kids, our parents had a large map of the world on our bedroom wall, something which we saw every day from infancy until that house burnt down.
I think that wall map helped broaden what would otherwise have been a very parochial 1950s Aussie worldview.
In this day and age, there is another graphic, which didn’t exist in the 50s, which helps young people understand the context of life (including health issues) and that is a schematic diagram of the chemical metabolic pathways of single mammalian cell.
You would need a print shop to make a large enough wall graphic. The result is so complex that this diagram is something you could gaze at, every day for a decade, and see something new every time you looked at it. Anyone who became familiar with this diagram would posses a rare sense of context, especially whenever they were exposed to some over-simplified rubbish about health by their doctors or in the media.
The full download of this schematic is 40mb; https://heyliam.com/wp-content/uploads/2016/08/metabolic_pathways-1-scaled.png
Note that even this schematic is simplified: it doesn’t mention electrical or magnetic pathways.
Scientists have won Nobel Prizes forfiguring out little bits of this giant puzzle e.g.
Hans Krebs – Citric acid cycle and Urea cycle Otto Warburg – cellular respiration cycle Albert Szent-Györgyi – the biological combustion process, vitamin C and the catalysis of fumaric acid”.
Erwin Neher and Bert Sakmann – single ion channels in cells Manfred Eigen – extremely fast chemical reactions in cells Konrad Bloch and Feodor Lynen- the mechanism and regulation of the cholesterol and fatty acid metabolism in cells
If I was raising some small kids, this is what I would have this on their bedroom wall. It gives us a perspective of the majesty of mother nature.
