The quiet architecture of an attention-free afternoon
On the best kind of afternoon, your desk catches a slice of sun and the only thing competing for your attention is the book in front of you. Reading on the web used to feel something like that. Then the pages started shaking and rearranging themselves around you.
What follows is an argument for reclaiming a little of that stillness—a way to turn any article into something that just sits still and lets you read.
Quote this in the essay intro—ties back to Carr's attention argument. Compare to James Bridle ch. 3.
Annotate anything
Take beautiful notes on any page.
Sticky notes and highlights in eight colors—drop them anywhere on the page. A built-in dictionary for words you don't know. And edit mode lets you reshape the page itself: cut clutter, fix the parser, mark it up like it's your own textbook.
en.wikipedia.org/wiki/Photosynthesis
Photosynthesis
Photosynthesis is the biological process by which plants, algae, and certain bacteria convert light energy into chemical energy. This energy is stored in the bonds of glucose molecules, synthesized from carbon dioxide and water.
The process takes place primarily in the chloroplasts of plant cells, where the green pigment chlorophyll captures photons across a broad range of visible wavelengths. Chlorophyll absorbs most strongly in the blue (around 430 nm) and red (around 662 nm) regions of the spectrum, reflecting green—which is why leaves appear green to the human eye.
Photosynthesis is the dominant source of atmospheric oxygen on Earth, and the ultimate basis of nearly every food chain on the planet.
Quiz Tues — memorize the two stages: light reactions, then Calvin cycle.
Mnemonic: Photons → ETC → ATP + NADPH. Prof. Chen said this 3x.
C4 vs CAM plants — ask Prof. Chen.
