Urban Ore

Cycled south. Plenty of curlews, cormorants and pelicans basking in the afternoon sunshine. Nature reserves, freeways, bay views and industry side by side. Explored the industrial area that runs along the rail track, lots of stunning modernist warehouses and came across a great structure containing organised piles of detritus, called Urban Ore.

Picked up some 1950's documents on the Sun, and other great physics books, one of them 'Concepts of Motion'.
