Caudwell’s Crisis in Physics does some of this but for quantum mechanics. You’d love the read.
Really its done science first approach then dialectics to examine the environment your project’s developed in for anything weird that will diminish understanding, then fix and repeat since there’s no such thing as perfection in reality. You don’t go in with dialectics first, that won’t do you good and just make you overly rigid without proper knowledge and limit your understanding of the situation at hand leading to silly errors. Gotta ground yourself in what is known of reality first.
It is neat for thought experiments for project design too and is a way to break out of the ‘its x or y or a mere continuum’ to noticing 'gee this doesn’t fit my data nor my problem, necessity v sufficiency for instance develops from this line of approach (and others, there are many tools in the tool kit, dia is just one) and is beyond helpful in life sciences.
Yes. If you’re poorer you struggle attaining popular beauty, which is very youth and fit oriented, even outside of obvious cosmetics, good sleep, good hydration, proper nutrition and movement help keep down microwrinkles and later on wrinkles along with keeping you toned looking. Then there’s things like temperature and the right amount of sunlight. Not to mention constant stress without relief.
Cheap cosmetics are more likely to irritate your skin and look off in certain lightening, expensive cosmetics are more forgiving and last longer, making me think of a cosmetics version of the Sam Vines boots theory. This applies to lotions and such to a degree. Clothing is an obvious one and fashion is fickle and fast.
I’ve noticed in the very, very impoverished rural area I live in people generally look a good 10-20 yrs older than they really are and just haggard and prematurely wrinkled. Worst I saw was some early 20yos at work I would have guessed easily for 40. Growing up in a similar area, some of my classmates in high school were already balding.
