China

In the 1980s and early '90s, Japan seemed poised to overtake the United States. I remember "Japan-bashing", and concern there was too much Japan-bashing. But by and large, there was the sense Japan deserved its success. Their education system was better, it was thought; their people worked harder; we Americans had been caught lazy and short of discipline. One remedy was karate class for your kids.

Whether any of that was true is almost irrelevant. Discipline is a virtue, and karate practice hasn't ruined too many children.

Today we face a similar situation with China, and there is plenty of China-bashing. But I see little concern about the China-bashing and no reflection on why China has been able to do so well.

Instead, we say China is evil. Their government isn't a "democracy", in whatever watery sense of the word. Our own government is supposedly led by a fascist who was elected by a minority of voters, but at least it's democratic. We're told human rights are violated on an industrial scale in

Jonathan Blow on societal collapse

It's uncanny how closely this talk follows a line of reasoning I've been working on lately. If you're copied here, we may have discussed one or more of its aspects

Light

Light is made of photons.

Light has both color and brightness. Color is related to the energy of photons and brightness is related to the number of photons.

Color determines how light interacts with objects. Black surfaces absorb photons of all visible colors, while white surfaces reflect them. Glass is transparent to visible light; many materials are transparent to radio waves.

How many linear relationships in biology persist over more than 6 orders of magnitude?

Whether a given dose is hormetic or deleterious should depend on the stress on the animal at the time of exposure. I conjecture that wartime stress could be responsible for deleterious effects in Japanese bomb survivors at ~ 100mSv, compared to other exposure cases that suggest hormetic effects at that dose.

The doubling dose for double-strand breaks is about 1.5 Gy per cell cycle.[^1] That is, ROS from normal metabolism are worth about 0.3 Gy/hour. DNA repair machinery is nearly at capacity at that level, so an additional 1.5 Gy can be deadly. Exercise seems to derive its benefits from stimulating the same systems [^2][^3] and whether it is good or bad also depends on one's existing stress level. Exercising a fatigued person is deleterious, but exercising a sedentary person is beneficial.

If oxidative stress is hormetic, antioxidant supplements may be harmful.[^4]
