Introduction to Scaling Laws

Galileo’s Discovery of Scaling Laws: https://www.mtholyoke.edu/~mpeterso/classes/galileo/scaling8.pdf
Days 1 and 2 of Two New Sciences

An example of such an insight is “the surface of a small solid is comparatively greater than that of a large one” because the surface goes like the square of a linear dimension, but the volume goes like the cube.5 Thus as one scales down macroscopic objects, forces on their surfaces like viscous drag become relatively more important, and bulk forces like weight become relatively less important. Galileo uses this idea on the First Day in the context of resistance in free fall, as an explanation for why similar objects of different size do not fall exactly together, but the smaller one lags behind.

It looks to me like best thing to do is accrue home equity (since it's partly shielded for financial aid purposes)&otherwise grin n bear it
It's pretty obvious that the 521 break mostly is a transfer from federal government to colleges and state budgets not to rich households.

huge popularity of "behavioral economics"among powerful people=largely excitement at how much more control they'd exert over stupider people

Time for Behavioral Political Economy? An Analysis of Articles in Behavioral Economics: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=1846184
This study analyzes leading research in behavioral economics to see whether it contains advocacy of paternalism and whether it addresses the potential cognitive limitations and biases of the policymakers who are going to implement paternalist policies. The findings reveal that 20.7% of the studied articles in behavioral economics propose paternalist policy action and that 95.5% of these do not contain any analysis of the cognitive ability of policymakers. This suggests that behavioral political economy, in which the analytical tools of behavioral economics are applied to political decision-makers as well, would offer a useful extension of the research program.

Research shows that Americans and conservatives can be less open to cues to change behavior.

Intermittent Fasting - Gwern.net
Our intuitive mental models are Aristotelian - strength or health are intrinsic qualities which can be developed by certain actions. But the reality is that exercise offers no intrinsic benefit to the body, no more than driving 10,000 miles in a car makes it more fuel-efficient or its tires more robust. Things wear down, in cars and cells. So why is exercise recommended? Because of the biological response to the damage caused by the exercise. Chemical pathways are activated, secretions unleashed, formerly silenced genes suddenly start expressing themselves, and things happen. Chemical cascades can be modified or interrupted by other chemicals, of course. We see proof of this in startling studies, like the consumption of antioxidants destroying the health benefits of exercise; why do antioxidants do that? Because the damage caused by exercise takes, in part, the form of oxidants, and the oxidants trigger some of those chemical pathways; the antioxidants neutralize & eliminate the oxidants, and so those pathways are muted or suppressed.

So much for exercise. Something similar is theorized about the much ballyhooed caloric restriction. It is not the number of calories that has any intrinsic meaning, which finesses any law of physics to enable greater longevity - it is the body’s reactions to the restriction that matters, the changing levels of sirtuin proteins. (Why would evolution not make this reaction the default reaction and would permit the organism to die before it absolutely had to? There are a number of models where aging helps genetic fitness, actually; just another reminder that Nature does not have our best interests at heart.) Presumably some of the pathways could be directly controlled by injecting additional enzymes even as calorie consumption remains intact, and for that reason a number of biotech/pharmacorps have been interested in the sirtuins and other chemicals linked to caloric restriction. All that matters is that the pathways get triggered. A little like a computer - it doesn’t care what a command or file means, it just cares whether the input satisfies whatever entirely arbitrary (from its point of view) criteria the computer holds at that moment.
