research & field notes
Proofs, teardowns, experiment logs, and reading notes from across the four frontiers — where the community's explorations, and the founder's, get written down and shared. Rigorous, in the open, and readable whether you have a PhD or you're teaching yourself tonight.

the credential gap, quantified
Why the pre-credential 18–22 builder falls through every existing door in deep tech — and what the numbers actually say about who does frontier work.
drafting
reading the connectome: network control theory for people who skipped the prereqs
A ground-up walkthrough of controllability on brain graphs — the math, the intuition, and why it matters for BCIs, in plain language.
drafting
what a $200 quadruped taught me about control
Sim-to-real, cheap servos, and the gap between a controller that works in theory and one that survives contact with the floor.
planned
cold, coherent, cheap: notes toward a dorm-room qubit
What’s actually stopping a determined undergrad from running a two-qubit experiment, and which parts of the stack are getting cheaper fastest.
planned
propulsion from first principles — a reading list
The papers, textbooks, and back-of-envelope models to go from “rockets are cool” to actually reasoning about Δv, nozzles, and staging.
