An independent field guide to interesting things

Follow the
interesting
thread.

A building leads to a railway. A railway leads to a hidden river. One good question opens a whole city. This is a place for curious detours through London, transport, science and the worlds we invent.

The first thread · London

A city made of layers

London is never just one thing. Its older routes, buildings and infrastructure keep shaping the city that gets built over them.

Field note 001 · London, unlayered

The old city inside the new one

Start with a familiar street. Look at what it sits on, what it replaced, and what survived by finding a new use. A first note on reading London as a stack of decisions rather than a finished picture.

Why the detour?

Curiosity rarely
takes a straight line.

The Tangentarium is a home for connected curiosities. It begins in London: a place where transport, architecture, history and daily life overlap in plain sight.

From there, the same method can travel—to chemistry, to other cities, to the carefully built logic of fantasy. Each subject gets its own doorway; the shared thread is the pleasure of looking closer.
