The historical tech tree is a project by Étienne Fortier-Dubois to visualize the entire history of technologies, inventions, and (some) discoveries, from prehistory to today. Unlike other visualizations of the sort, the tree emphasizes the connections between technologies: prerequisites, improvements, inspirations, and so on.

My daughter asked me recently why I spend so many evenings on the phone talking about school lunches. I told her about the kids who get their trays taken away. Her face scrunched up in that particular way that children’s faces do when they encounter an injustice so fundamental it cannot be reconciled with their understanding of how the world should work.

Sagan got it before anyone else!

I am surprised by how normal France feels.  People want to say “The French this, the French that…” but to me they are fairly Americanized, often speak good English, and have few truly unique cultural habits these days.

They also seem reasonably well adjusted, normal mostly in the good sense, and thus of course somewhat boring too.

Walking and driving through the less salubrious parts of town is a useful corrective, but I do not feel the place is falling apart.
