Examining 'The Witness': Light & The Science of Human Perception

In this episode, we are checking out the modernist color-lab bunker, and learning about the science of vision as The Witness continues to try and link-up first-person conscious experience and our third-person scientific models of the world. Highlights from this episode: 0:45 -- The core theme of this area, and why color is such a fascinating topic for The Witness -- "we can trace color so well from photons... through the retina and the brain", so it seems like a tantalizingly tractable place to understand the nature of qualia. 4:26 -- The island's volcanic geology, and how the wind and waves move around it 6:28 -- Color bunker vs Marsh tetrominoes, the relationship between these two modern-architecture, scientific/materialist-themed zones 9:36 -- The first puzzles, which don't engage with the color mechanic but just teach you to separate colors. 12:05 -- Why is the bunker a bunker? idk! But it is currently being used for agricultural experiments, as I mention at 8:25. 14:00 -- The physics of color perception, from photons to neurons! (Here is that cool python talk about color theory that I mention: https://medvis.org/2016/02/23/better-...) 21:21 -- How the brain does image classification, from the retina to abstract thoughts in the brain! But despite all this understanding, we don't understand where the subjective experience of color ("qualia") comes from... 29:38 -- More puzzles, and how yellow/cyan/magenta filters impact light, each of which remove one primary color (yellow removes blue, cyan removes red, magenta removes green). These are the first puzzles that actually engage with the color themes of the area. 30:04 -- Two-color-process movies from the 1910s! https://en.wikipedia.org/wiki/RG_colo... 40:18 -- More puzzle panels introducing complex intermediate colors and shades. 46:55 -- Exploring the monochrome rooms of the flower-tower! 50:57 -- Trying to reason through the elevator puzzle in the flower tower. 1:01:10 -- An Arthur Eddington quote about the absence of qualia in the empirical world of scientific description, and emphasizing the strangeness of the "real" world of photon wavelengths and differential equations. 1:07:12 -- Commenting on a minor colorblindness-accessibility complaint that people made about The Witness. But they aren't understanding that these puzzles are actually ABOUT the nature of color, rather than merely being symbolic designators of enemies/allies or etc. If you'd like, fill out this quick survey to let me know which video ideas you're most interested in: https://forms.gle/s8NQzjZeLL8VfSos6 And for more of my work, you can also visit https://jacksonw.xyz/ or peruse my writings on effective altruism at https://forum.effectivealtruism.org/u...
