Working on curriculum and I've fallen into the same sort of trap that I fell into, back in my college days, while researching papers. I'd always find interesting tangents and end up down several rabbit holes.

Today, I've explored the physics of light; followed the process of the albumen film processing method; learned more about the art styles of pictorialism, dadaism and surrealism; learned about propaganda from the Bolsheviks and how it transformed later under Stalin; realized how the photography I adore from the Farm Security Administration is also propaganda; rediscovered the poem by Lord Alfred Tennison "Charge of the Light Brigade" after seeing a photograph taken a year later by Roger Fenton.
