ALL IS MOTION
A research programme on motion and the traces it leaves: how past activity produces them, and how it can be reconstructed from them.
Research proposition
Archaeological evidence is not simply a collection of objects. It is the observable residue of processes unfolding through time.
01 / The programme
From motion to trace. From trace to motion.
The programme works in two directions. The forward model runs from motion to trace: given a motion, what traces must it leave? The inverse model runs from trace to motion: given the traces, what motion made them?
Forward model: motion → trace
Start from a process — a body, a material, a movement — and predict the traces it must leave. A paper in draft, Technology as Boundary-Extending Motion, builds this for hominin evolution, tested against stone tools from Lomekwi 3, 3.3 million years ago, onward.
Inverse model: trace → motion
Start from the traces as they exist now — stones, deposits, distributions — and reconstruct the motions that produced them. The IEEE paper of 2025 builds this as signal reconstruction.
01
Motion
Processes occur through time. Change is fundamental.
02
Signal
Processes leave measurable information in their environment.
03
Trace
Archaeology encounters transformed and incomplete signals.
04
Reconstruction
Inference moves from observed traces toward generating processes.
05
Prediction
Models become useful when they generate testable expectations.
Steps 01 to 03 are the forward model; 04 and 05 the inverse. The two meet in the test: the forward model predicts the traces, and the inverse method must recover the motion from them.
02 / The way there
Simple to state. Not simple to get there.
Both directions sound obvious. Getting there means undoing the way archaeology has represented its evidence — as discrete objects, epochs and layers — and that is where every part of this site comes in.
Foundation
Why it is hard
Parmenides’ One, the infinite objects and infinite times problems, and Zeno’s arrow: the errors in the way, and the 2,500-year-old method that clears them.
Signal science
Trace to motion
How past activity becomes a signal, how the signal decays, and how it can be reconstructed: the inverse model, from SETI to the Record of Monuments and Places.
Archaeology
The evidence
Records, survey and excavation: the material the models are built from and tested against.
Engineering & design
Motion to trace
Robotics is measurable motion. Machines designed for repair and persistence, and the Astromech Droids series.
Industrial Automata
The project
Universal maintenance technology, built on the same principles.
Series & essays
The problems in action
Local and national history — Sligo, Streedagh, the round towers — where the method meets real places.
Robotics as the forward model
We cannot see the Stone Age. But we can rerun it.
No one watched the motions that made a stone tool 3.3 million years ago. But a machine can repeat them: build a body that moves, run the motion, and measure both the motion and the trace it leaves.
Robotics is measurable motion: the forward model in action, with the link between motion and trace known rather than inferred. That is why a droid sits beside the archaeology on this site.
We are going to rerun the Stone Age as best we can — and you’re invited along for the journey.
