“The shorter wavelengths, those that we sense as violet and blue light, are more efficiently scattered than the longer wavelengths—those that we sense as orange and red light. When we look up on a cloudless day and admire the blue sky, we are witnessing the preferential scattering of the short waves in sunlight. ...
So why is the sunset red? The red of the sunset is what's left of sunlight after the air scatters the blue away. Since the atmosphere is a thin shell of gravitationally bound gas surrounding the solid Earth, sunlight must pass through a longer slant path of air at sunset (or sunrise) than at noon. Since the violet and blue waves are scattered even more during their now-longer slant path through the site than when the Sun is overhead, what we see when we look towards the sun is the residue—the waves of sunlight that are hardly scattered away at all, especially the oranges and reds. A blue sky makes a red sunset.”

“Storing data is so cheap it's essentially free, so data brokers record everything in the hopes that it will have value to someone. The data is aggregated by third parties, linked to individual identities, and sold like any other consumer data. It's not a conspiracy. It's an economy, but an economy these people know nothing about. They're tagged like sheep and have as much say in the matter as sheep.”

“Capitalist market economies are "composed of a collection of unequal individuals who compete for greater shares of money as the medium of exchange ... this model of community legitimates relations of domination either by denying they exist or treating them as inevitable."
